摘要： A piston compressor includes a rotary valve (35) having a suction guide hole. A plurality of introducing passages are formed in a cylinder block to connect compression chambers to the rotary valve (35). The inner circumferential surface of each cylinder bore has a suction auxiliary recess (61), which is connected to the outlet of the corresponding introducing passage in the circumferential direction of the cylinder bore at the end of the cylinder bore facing a valve assembly. Therefore, the compressor reduces suction resistance of gas at the beginning of the suction stroke without enlarging introducing passages formed in the cylinder block.

摘要： A vehicle air conditioning apparatus includes a refrigerant circulation circuit. The vehicle air conditioning apparatus has a variable displacement type compressor (10), a first pressure monitoring point (P1), a second pressure monitoring point (P2) and an oil separator (12) in the refrigerant circulation circuit. Also, the vehicle air conditioning apparatus has a control valve (CV) in the compressor. The compressor compresses refrigerant gas. Displacement of the compressor is variable. The refrigerant gas includes oil. The second pressure monitoring point is located more downstream than the first pressure monitoring point. The control valve controls the displacement based on differential pressure between the first and second pressure monitoring points. The oil separator is located between the first and second pressure monitoring points in order to separate the oil from the compressed refrigerant gas, thereby the oil separator serves as means for manifesting the differential pressure.

摘要： A refrigeration suction mechanism used in a piston type compressor. The compressor includes a cam member mounted on a rotary shaft for the integral rotation with the rotary shaft. The rotary shaft has a refrigerant passage extending therethrough. The cam member converts a rotation of the rotary shaft to a linear reciprocating movement of pistons in cylinder bores arranged around the rotary shaft. Each of the cylinder bores defines a compression chamber by the associated piston. The refrigerant being introduced to, compressed in and discharged from the compression chamber when the piston is in a suction stroke, a compressing stroke and a discharge stroke respectively. A reaction force is generated in the compression chamber and acts on the piston when the piston (29, is in the discharge stroke. A rotary valve (35, 36, located adjacent to the rotary shaft (21, includes an introducing passage (31, 32, 57, that is in communication with the refrigerant passage. A suction passage 33A, 34A, is connected to each cylinder bore (27, 27A, 28, at its one end and selectively connected to and disconnected from the introducing passage (31, 32, 67) in accordance with the rotation of the rotary valve (35, 36, The reaction force acting on the piston (29, is transmitted to the rotary valve (35, 36, to urge the rotary valve (35, 36, 63) against the other end (331, 341, 581) of the suction passage 33A, 34A, connected to the cylinder bore (27, 27A, 28,

摘要： A piston type compressor has introducing passages, each extending from one of compression chambers, and a cylindrical rotary valve located between a suction pressure zone and the introducing passages. An opening of each of the introducing passages has an advanced area a part of that is inclined relative to an axial direction and a circumferential direction of the rotary valve. The rotary valve has a residual gas bypass passage. The residual gas bypass passage connects a high pressure introducing passage through the introducing passages, which communicates with the high pressure compression chamber after the discharge stroke ends, to a low pressure introducing passage, which communicates with the low pressure compression chamber. When a high pressure opening of the residual gas bypass passage starts to be connected with the opening of one of the introducing passages, an advanced area of the high pressure opening of the residual gas bypass passage extends along the advanced area of the opening of the introducing passage.

摘要： A piston type compressor includes a housing, a refrigerant gas passage and a rotary valve. The housing defines a suction pressure region. The refrigerant gas passage interconnects the suction pressure region with at least a compression chamber. The rotary valve includes a suction guiding hole which forms a part of the refrigerant gas passage. The suction guiding hole connects each compression chamber by turns with the suction pressure region as the rotary valve is rotated. The suction guiding hole communicates with a plurality of the compression chambers at least at early and last stages in a suction process. The suction guiding hole has a predetermined area per unit length in a rotational direction of the rotary valve. The predetermined area gradually increases from a preceding side of the rotation of the rotary valve to a middle and gradually decreases from the middle to a following side of the rotary valve.

摘要： A rotary valve operationally connected to a rotary shaft is housed so as to be slidably rotatable in an accommodation hole formed in a cylinder block. A suction valve mechanism functions so as to introduce refrigerant gas in a suction chamber into a compression chamber. A gas suction passage leading from the suction chamber to the compression chamber can be opened and closed in synchronism with rotation of the rotary shaft. In an outer circumferential surface of the rotary valve is formed a groove constituting a part of a gas vent passage for introducing the refrigerant gas in a crank chamber into the compression chamber.
