摘要： A compressor bypass passage has an inlet portion and an outlet portion which is connected to the suction passage. The inlet portion of the bypass passage has an opening which is able to be open to the compression chamber when the compression chamber is in a decreasing volume stroke, thereby to spill the refrigerant from the compression chamber into the suction passage. A control pressure chamber is formed in the housing. A valve member is arranged in the inlet portion of the bypass passage. The valve member is actuated in response to a variety of pressures of the refrigerant in the control pressure chamber for adjusting the area of the opening of the inlet portion of the bypass passage. A pressure supply passage for supplying a refrigerant, which pressure is higher than the pressure in the suction passage, is connected to the control pressure chamber. A spill passage for spilling a part of the refrigerant interconnects the control pressure chamber to the suction passage. A pressure control valve is arranged in the pressure supply passage or in the spill passage for controlling the pressure in the control pressure chamber.

摘要： A rotary vane type compressor provided with a rotor member arranged eccentrically in the cylindrical housing. Vane plates are radially slidably arranged in the rotor member, so that the vane plates always contact an inner cylindrical surface of the housing. Valve means are provided for a positive close-off of the supply of oil during non-operation of the compressor while maintaining a supply of oil in a necessary amount during operation of the compressor. The compressor further includes an oil reservoir arranged in the rotor member for storing an amount of oil to be directed to a pair of bearing units.

摘要： A rotary compressor includes a cylindrical-shaped housing, a rotor rotatably mounted in the housing and formed with diametrically extending slits, and a pair of movable vanes each slidably disposed in each of the slits with its opposite ends extending beyond the associated slit in abutting relation to the inner surface of the housing. The clearances between the movable vanes and the slits of the rotor are made larger about the central portion of the rotor than adjacent to the outer periphery thereof by making each of the vanes thinner about its central portion than at its opposite end portions or making each of the slits wider about the central portion of the rotor than adjacent to the outer periphery of the rotor. With the arrangement, shearing stresses caused by shearing of oil in the compressor can be suppressed to thereby reduce a loss in the torque of the compressor, and the maximum stress on the movable vanes can be limited below an allowable stress to improve the anti-breakage characteristics of the vanes.
摘要翻译：旋转式压缩机包括：圆筒形壳体，可旋转地安装在壳体中并形成有径向延伸狭缝的转子和一对可动叶片，每个可动叶片可滑动地设置在每个狭缝中，其相对端延伸超过相邻狭缝的邻接关系到壳体的内表面。通过使每个叶片围绕其中心部分比在其相对的端部处更薄，或者使每个叶片的中心部分比其相对的端部部分更薄，使得可动叶片和转子的狭缝之间的间隙围绕转子的中心部分比其外周更大围绕转子中心部分的狭缝比与转子的外周相邻。通过该结构，可以抑制由压缩机中的油的剪切引起的剪切应力，从而减少压缩机的扭矩损失，并且可动叶片上的最大应力可以限制在允许应力以下以改善抗断裂叶片的特点。

摘要： A rotary compressor is provided with a rotary valve arranged rotatably in the housing unit. The rotary valve is partially exposed to an interior space of the housing unit. The interior space is divided into a plurality of variable working spaces. A return port is formed in the rotary valve for feeding a cooling medium into an inlet port from the working space. A quantity of the cooling medium discharged from the working space through an outlet port is changed in accordance with the rotation of the rotary valve controlled by the actuator.

摘要： A rotary compressor formed with an unloading port maintaining a working space in communication with a suction chamber and opened and closed by a valve, to vary the capacity of the compressor. The internal pressure of the working space is sensed in a compression stroke or this pressure and the pressure of a fluid drawn by suction are both sensed, so as to open and close the valve based on the sensed internal pressure of the working space or the pressure differential between the internal pressure of the working space and the pressure of the fluid drawn by suction, to give suitable hysteresis to the operation characteristics of the on-off valve to stabilize the operation of the on-off valve.

摘要： A rotary compressor including a housing having therethrough a cylindrical bore, end plates attached to the housing to close the open axial ends of the bore respectively, an eccentric rotor rotatable in the bore and vanes slidably mounted in the rotor. A working chamber defined between the adjacent pair of vanes communicates with a discharge chamber outside of the housing through a discharge opening in the wall of the housing. First and second passages have their respective one ends opening to the cylindrical bore and the respective other ends communicating with the discharge chamber. The one end of the first passage is positioned at a location or adjacent thereto where the leading one of the adjacent pair of vanes is positioned when the working chamber defined therebetween has its volume starting to decrease. The one end of the second passage is positioned at a location where the one end of the second passage together with the discharge opening is opened to one of the discharge chambers with the latter having its volume decreased and communicating with the discharge opening. First and second check valves respectively in the passages are opened only when the working chambers respectively associated with the passages have therein pressures higher than respective predetermined values.

摘要： A system for measuring amounts of particulates exhausted from a vehicle internal combustion engine, such as a diesel engine, has a dilution tunnel into which exhaust gas is introduced and mixed with and diluted by clear air. One part of the diluted gas is introduced into a first sampling arrangement in which a first filter is provided for collecting particulates of dry soot and another part of the diluted gas is introduced into a second sampling arrangement in which a second filter is provided for collecting particulates of soluble organic fraction (SOF). The amounts of dry soot and SOF are calculated in a real time manner in accordance with the pressure drops across the filters on the basis of the time differential of the signals output from pressure transducers provided for each filter.
