摘要： PURPOSE:To prevent the excessive supply of oil for a compression chamber by a method wherein an oil path is closed by a control valve mechanism provided in an oil supplying path connecting the oil sump and the compression chamber under a condition that the compressor has been stopped. CONSTITUTION:Under a condition that the operation of the compressor is stopped, a pressure in the compression chamber 6 leaks to the side of a suction chamber 9 through a gap formed between a rotor 5 as well as vanes 8...8 and both side plates 3F, 3R, therefore, pressures of respective parts in the compression chamber 6 become the same as a suction pressure. As a result, pressures in a high pressure chamber 23 and a low pressure chamber 24 become the same in the control valve mechanism 21 for opening and closing a path, which is provided in the oil supplying path 20 connecting the oil sump 17 and the compression chamber 6. A spool 22 is energized toward the high pressure chamber 23 by a spring 25 and blocks the oil supplying path 20, therefore, supply of oil for the compression chamber 6 is stopped and the excessive supply of the oil may be prevented.

摘要： PURPOSE:To prevent a reversed flow of gas to the suction side due to the engagement of rotors during the suction, decrease the suction pulsation, suppress unpleasant noises, and improve the volume efficiency by inserting a baffle plate between a suction port and rotors. CONSTITUTION:When a male rotor 7 and a female rotor 8 are rotated, the inflow gas is introduced into a space formed by a tooth profile gap between the male rotor 7 and female rotor 8 and the inner peripheral surface of housing spaces 5, 6 and is shifted while being joined and compressed at the boundary portion between the housing spaces 5, 6. The gas entering a suction chamber 17 during the compression action is guided by a baffle plate 19 and is shifted to the tip portion 17a of the suction chamber, thus being made easy to enter into a compression chamber 25, and the volume efficiency is improved. In addition, the gas periodically blown up toward a suction port 18 when a tooth profile passes due to the rotation of both rotors 7, 8 is bent to the compression chamber side 25 by a baffle plate 19, thus inflicting no effect on the inflow gas.
摘要翻译：目的：为了防止由于吸力过程中转子的接合而导致气体向吸入侧的反向流动，通过在吸入口和转子之间插入挡板来减小吸入脉动，抑制不愉快的噪音并提高体积效率。构成：当阳转子7和阴转子8旋转时，流入气体被引入由阳转子7和阴转子8之间的齿廓间隙和容纳空间5,6的内周面形成的空间中，在容纳空间5,6之间的边界部分被接合并被压缩。在压缩作用期间进入吸入室17的气体由挡板19引导并移动到吸入室的顶端部分17a，从而容易进入压缩室25，并且提高了体积效率。此外，当由于两个转子7,8的旋转引起的齿廓通过时，气体定期地向吸入口18吹出的气体被挡板19弯曲到压缩室侧25，从而对流入气体没有影响。

摘要： PURPOSE:To prevent the breakdown of parts such as a rotor, a vane and the like when liquid compression happens as well as to improve the durability of a compressor, by setting a formation range for an intermediate pressure groove for the purpose of interconnection between the intermediate pressure groove and a vane back pressure chamber. CONSTITUTION:As shown in illustration, formed in front of a rear side plate, a semicircular intermediate pressure groove 28 interconnecting a compression chamber 17 starts its interconnection with a back pressure chamber 15a when the tip of a vane 16' is shifted to a position C at the initial stage of suction stroke, and this is formed so as to cause the back pressure chamber 5a of the succeeding vane 16' to separate from the intermediate pressure groove 28 when the compression chamber 17 formed by the vane 16' and a vane 16 going a head of the vane 16' is interconnected with a discharge port 19. With this, even when liquid compression happens in the compression chamber 17, pressure in the compression chamber 17 escapes to a discharge port 20 via the discharge port 19 whereby the compression chamber 17 will not come into a state of being unusual high pressure, thus the breakdown of related parts can be prevented.

摘要： PURPOSE: To mitigate over-compression by a method wherein an over-compression mitigating section, whose gap between the top surface of a piston and the end wall of a cylinder is larger than the same of a section around a delivery port, is provided at a distant position in a direction orthogonal to the moving direction of the piston.
CONSTITUTION: The top surface 68 of the piston 18 is provided with four sets of circular holes with bottom 72W75 at parts whereat the flow of refrigerant gas is precluded or distant parts from positions opposing to the delivery ports 42. According to this method, the volume of refrigerant gas is enlarged by a volume corresponding to the volumes of the bottomed circular holes 72W75 and the rate of volumetric change of the refrigerant gas in accordance with the advance of the piston 18 is reduced. Accordingly, the compressing rate of the refrigerant gas is reduced and the over-compression thereof may be mitigated.

摘要： PURPOSE: To prevent leakage of oil through an on-off valve, by a method wherein the on-off valve, having a valve rod which is moved from a shut-off position to a communicating position when the solenoid of an electromagnetic clutch is excited, is located halfway along an oil feed passage interconnecting an oil reservoir and a compression chamber.
CONSTITUTION: A spool type on-off valve 86 is located in a front side plate 10 located halfway along an oil feed passage 82. With a solenoid 54 excited, rotation of a pulley 50 is transferred to a rotor 20, and simultaneously, an iron piece 90 is magnetized to move a spool 92 of the on-off valve 86 to a position where the spool is forced into contact with the iron piece 90 against a spring 96. This causes the oil feed passage 82 to be communicated with a communicating groove 94, and lubricating oil in an oil reservoir 78 to be fed to an oil groove 82 through the oil feed passage 82 by the discharge pressure of a compressor. The lubricating oil is admitted in the inner end part of a vane groove 60, and is fed in sliding surfaces between a rotor 20 and the front side plate 10, a vane 58 and the vane groove 60, and a rear side plate 12 and the rotor 20 to effect lubrication and sealing.

摘要： PURPOSE:To improve follow-up characteristics in an unload device, by installing a throttle valve in a suction passage of a compressor, and in time of a drop in suction pressure for a short period of time, keeping the throttle valve unoperated intact. CONSTITUTION:At the opening side part of a casing 96, a through hole 104 crossed at right angles with an empty chamber 98 is made up there. In this through hole 104, its flow passage area is formed so as to be throttled by a piston 100 in a state that the piston 100 moves forward against the energizing force of a spring 106. When operation gets started, suction pressure drops to some extent whereby a throttle valve 109 is set in motion, so that pressure inside an inner space 103 is gradually released via an interconnecting hole 108, and the opening of the through hole 104 grows large.

摘要： PURPOSE:To facilitate the changeover between loading and unloading by varying the amount of eccentricity of a rotor, in a device to obtain compression through the swinging rotation of said rotor and the extention and retraction of blades which are slidingly brought into contact with the outer surface of said rotor. CONSTITUTION:During unloading operation with an air-conditioning switch off, the spool 28 of a closing valve mechanism 26 closes a supplying passage 25b, a slider 8 is pressed to the right due to a spring 10, and a cam cylinder 11 and a rotor 13 are held concentrically with a rotary shaft 6. Therefore, in this state, the swinging rotation of the rotor 13 is not obtained if the rotary shaft 6 is rotated, without carrying out the compression of refrigerant. When the airconditioning switch is turned on exciting an electromagnet 30, the blockage of the supplying passage 25b due to the spool 28 is released allowing the slider 8 to travel to the left, and increasing the amount of eccenticity of the cam cylinder 11 with the rotary shaft 6. Thus, the rotor 13 is swingingly rotated due to the rotation of the rotary shaft 6 thereby compressing the refrigerant.

摘要： PURPOSE:To miniaturize the compressor and facilitate the manufacture thereof by a method wherein an unload hole is formed on a rotor casing at a part surrounding a compression chamber under a compression stroke while an unload valve is fitted into the unload hole. CONSTITUTION:The unload hole 60, vertical to the central axis of a rotor 20 substantially, is formed on the rotor casing 10 at the part surrounding the compression chamber under the compression stroke while the unload valve 64 is fitted into the unload hole 60. According to this method, the unload hole 60 may be opened by the relatively small amount of movement of the unload valve 64 and a sufficient delivery capacity decreasing effect may be obtained, therefore, an unload valve driving means may have a small size and the size of the compressor will never be englarged. The unload valve 64 is only sliding in the unload hole 60, therefore, the management of the clearance of the slide valve therefor may be loosened and the manufacture thereof may be facilitated.

摘要： PURPOSE:To permit to reduce the power load of the compressor by a method wherein the opening degree of a control valve is regulated by utilizing a pressure difference generated between both pressure chambers to control the supplying amount of refrigerant gas to the compressor. CONSTITUTION:The vacuum condition of the pressure chamber 12A is obtained in delayed timing due to the choking effect of a choking hole 15. The pressure difference is generated during this period between both pressure chambers 12A, 12B. The choking effect with respect to a suction pipeline 8 is obtained by the pressure difference and an effect to regulate the supplying amount of the refrigerant to the compressor 2 may be obtained. That means that a small capacity operating condition is obtained in the compressor 2 and the effect to reduce the power load of the compressor may be obtained in a value corresponding to the small capacity operating condition.

摘要： PURPOSE:To prevent a vane tip from imposing excessive pressure contact on the inner circumferential surface of a cylinder, by installing a high pressure groove, which makes discharge pressure act on a back pressure chamber of a vane, for the duration the vane tip is shifted to a position at the initial stage of suction stroke by way of a top position from the discharge completion position. CONSTITUTION:For the duration the tip of a vane 16' is shifted to a position at a suction stroke initial stage B by way of a top position T from an almost nearly discharge completion position A, a high pressure groove 26 to make the discharge pressure act on a back pressure chamber 15a of a vane 16 is installed. With this, for the said buration when compressive operation does not take place, pressure in the back pressure chamber 15a can be released from such pressure as higher than the discharge pressure whereby the tip of the vane 16' avoids pressing excessively on the inner circumferential surface of a cylinder 1, reducing power loss to a degree, and wear in a vane 16 or the like can be lessened. Also, for the duration the vane 16' is shifted to a position corresponding to the succeeding vane 16 to form a compression chamber 17 at a time when the compression chamber 17 is interconnected to a discharge port 19, from the suction stoke initial stage B, an intermediate pressure groove 28 to interlock the back pressure chamber 15a is installed, thus an unusual high pressure ratio of the compression chamber 17 is prevented.
