摘要： A Roots pump rotates a plurality of rotors by a pair of rotary shafts to draw gas. Each rotary shaft extends through a rear housing member of the Roots pump. An annular shaft seal is fitted around each rotary shaft and is received in a recess formed in the rear housing member. A helical groove is formed in a circumferential side of each rotary shaft. Each helical groove urges oil between the circumferential side of the associated shaft seal and the circumferential wall of the recess to move from a side corresponding to pump chambers toward a gear accommodating chamber when the associated rotary shaft rotates. This preferably prevents oil from leaking to the pump chambers.

摘要： Compressors may include a compressor housing having a compression chamber defined within the compressor housing. The compression chamber is preferably arranged and constructed to compress and discharge a fluid drawn into the compression chamber. A unit housing may be coupled to the compressor housing. A control device may be disposed within the unit housing and the control device preferably controls electric components of the compressor. Further, a suction passage is preferably defined to introduce the fluid into the compression chamber. The suction passage preferably penetrates through the unit housing so as to directly cool the control device due to the fluid flowing through the suction passage.

摘要： A displacement control apparatus controls the displacement of a variable displacement controller. A drive shaft of the compressor is driven by an engine. Torque acting on the drive shaft represents the displacement. The apparatus includes a control valve, an air conditioner controller and a compressor controller. The control valve changes the compressor displacement. The air conditioner controller produces a torque setting signal, which represents a target torque, to the compressor controller. The compressor controller changes the valve opening based on the torque setting signal such that the actual load torque matches the target torque value. Accordingly, the compressor is controlled according to the torque. The air conditioner controller may send the torque setting signal to an engine controller, which eliminates the need for load torque maps.

摘要： A refrigerant circuit includes a compressor and an expansion valve. The expansion valve is connected to a discharge muffler of the compressor by a high pressure conduit. The expansion valve is also connected to a suction passage of the compressor by a low pressure conduit. The high pressure conduit includes a condenser and the low pressure conduit includes an evaporator. A check valve is located between the discharge muffler and the high pressure conduit to selectively connect and disconnect the high pressure conduit with the discharge muffler. A relief valve is attached to the discharge muffler upstream of the check valve. If the pressure in the compressor is abnormally high when the check valve closes, the relief valve releases the abnormally high pressure from the discharge muffler. Therefore, if the check valve fails to function, the relief valve prevents the pressure in the compressor from being abnormally high.

摘要： A variable displacement compressor having a pressurizing passage, which extends through a cylinder block. The pressurizing passage connects a discharge chamber and a crank chamber. A valve is arranged in the pressurizing passage. A drive shaft rotates and produces centrifugal force that causes the valve to open the pressurizing passage. The pressure of the crank chamber is increased when the rotation of the drive shaft is accelerated thereby opening the pressurizing passage with the valve. This moves a swash plate such that its inclination, relative to a plane perpendicular to the drive shaft, decreases. As a result, the compressor shifts from a maximum displacement state to a minimum displacement state, which improves the acceleration performance of an engine connected to the compressor. Furthermore, the displacement of the compressor in the minimum displacement state is 50% of that in the maximum displacement state. This prevents an excessive decrease in the cooling capability of the compressor.
摘要翻译：一种可变排量压缩机，其具有延伸穿过气缸体的加压通道。加压通道连接排气室和曲轴室。阀设置在加压通路内。驱动轴旋转并产生使阀打开加压通道的离心力。当驱动轴的旋转加速时，曲柄室的压力增加，从而用阀打开加压通道。这使得斜盘相对于垂直于驱动轴的平面的倾斜度减小。结果，压缩机从最大位移状态向最小位移状态转变，这提高了连接到压缩机的发动机的加速性能。此外，压缩机在最小排量状态下的位移是最大排量状态的50％。这防止了压缩机的冷却能力的过度降低。

摘要： A compressor has a control valve that adjusts the pressure difference between a crank chamber and a cylinder bore for controlling the inclination of a drive plate. The control valve protrudes outward from the compressor housing. The compressor also has a support protruding outward from the front housing and a leg protruding outward from the cylinder block. The outer ends of the support and the leg extend further from the compressor than the furthest extremity the control valve. Therefore, when the compressor is placed on a flat surface, the support and the leg prevent the control valve from contacting the surface. This protects the control valve from damage during transport and handling.

摘要： A control valve for a variable displacement compressor. The control valve has a valve body for regulating a gas passage. A bellows actuates the valve body in accordance with an operating pressure introduced to a pressure sensing chamber. A solenoid biases the valve body with a force based on the electric current supplied to the solenoid. A cylindrical cap is fitted to a cylindrical portion provided on a housing of the control valve. The bellows is located in the pressure sensing chamber. The axial position of the cap in relation to the cylindrical portion is adjusted such that the bellows is positioned at a specific initial position when a pressure having a predetermined magnitude is introduced to the pressure sensing chamber and when a current having a predetermined value is supplied to the solenoid. The cap is secured to the cylindrical portion by crimping with the bellows positioned at the initial position.

摘要： A control valve in a compressor that adjusts the discharge displacement based on controlling of an inclination of a cam plate. The compressor includes a supply passage for connecting a discharge chamber with a crank chamber. The control valve is placed midway on the supply passage. The control valve has a valve body. The valve body moves in a first direction to open the supply passage and moves in the second direction to close the supply passage. A reacting member reacts to suction pressure. A first transmitting member is placed between the reacting member and the valve body. A solenoid is opposed to the reacting member with respect to the valve body. The solenoid urges the valve body in the second direction via a second transmitting member when the solenoid is excited. An urging device urges the valve body in the first direction, The first transmitting member connects the reacting member with the valve body to move the valve body toward or away from the reacting member. The urging device causes the valve body to fully open the supply passage when the solenoid is de-exited.

摘要： A compressor having a cam plate disposed in a crank chamber and mounted on a drive shaft. The cam plate is tiltable between a maximum inclined angle position and a minimum inclined angle position with respect to a plane perpendicular to an axis of the drive shaft according to a differential pressure in the crank chamber and in a cylinder bore. The cam plate varies the stroke of a piston based on an inclination thereof to control the displacement of the compressor. A supply passage connects a discharge chamber with the crank chamber to deliver the gas from the discharge chamber to the crank chamber. The supply passage has an inlet that is open in the discharge chamber. A control valve is disposed midway on the supply passage. The control valve adjusts the amount of the gas introduced into the crank chamber from the discharge chamber through the supply passage to control the pressure in the crank chamber. A filter is disposed at the inlet of the supply passage to filter the oil. The filter captures foreign matter mixed with the oil when the gas containing the oil is introduced into the supply passage from the discharge chamber.
