摘要： A valve plate or end cap includes a running surface having a pair of arcuate kidney ports formed thereon. The running surface also includes a plurality of pressure gradient grooves formed on the running surface, each pressure gradient groove having a proximal end adjacent to a respective one of the ends of one of the kidney ports and a distal end. The distal end of one of the pressure gradient grooves associated with one kidney port may overlap the distal end of a pressure gradient groove associated with the other kidney port. The distal end of at least one of the pressure gradient grooves is located outside the circumference of a pitch circle that passes through the center of each kidney port. The distal end of at least one of the other pressure gradient grooves is located inside the pitch circle circumference.

摘要： A vehicle air conditioning system includes a pressure reducing device that is operatively coupled to a condenser downstream therefrom. An evaporator is operatively coupled to the pressure reducing device downstream therefrom. A refrigerant flow booster is operatively coupled to the evaporator downstream therefrom and a compressor is operatively coupled to the refrigerant flow booster downstream therefrom, the compressor also being operatively coupled to the condenser upstream therefrom. The refrigerant flow booster increases the flow of gaseous refrigerant to the compressor, in particular, when the compressor is operating at slower speeds.

摘要： A low power rotation compressor includes a base, a rotation disk, a piston structure, and a casing. When the rotation disk is rotated, the piston structure is moved by rotation of the rotation disk, to co-operate with the cylinder structure and the slide-way, to press the air contained in the air collection container of the casing into the pressure storage container of the casing, thereby producing a required pressure simultaneously. Thus, the low power rotation compressor may use a low power motor to obtain a higher pressure and a higher air exhaust rate, thereby increasing the efficiency and decreasing the cost.

摘要： An axial piston rotary power device can be configured as a four-cycle and two-cycle internal combustion engine, a compressor, a pump, a fluid-driven motor or an expander. The device includes an external stator housing, an internal axial stator and a rotary cylindrical block attached to an end shaft that can rotate within the annular enclosure formed by the two stators. The cylindrical block contains a plurality of cylindrical cavities arranged as pairs of working cylinders. Each cylindrical cavity encloses a double-acting piston assembly comprising two piston heads connected to a middle portion having a pair of axially spaced apart roller cam followers that make roller contact with a guide cam surface protruding from the inside of the external stator housing. The action of the cam roller followers on the guide cam imparts rotation to the cylindrical block when the piston assemblies reciprocate within their respective bores.

摘要： When a suction pressure is lower than a set suction pressure, and a crank chamber pressure is higher than a control pressure in a second supply passage, a first valve body reduces an opening degree of a suction passage, and a second valve body opens a bleed passage. When the suction pressure is higher than the set suction pressure, and the crank chamber pressure is higher than the control pressure, the first valve body increases the opening degree of the suction passage, and the second valve body opens the bleed passage. When the crank chamber pressure is lower than the control pressure, the first valve body reduces the opening degree of the suction passage, and the second valve body closes the bleed passage.

摘要： A variable displacement swash compressor includes a housing, a drive shaft, a swash plate, a link mechanism, a piston, a conversion mechanism, an actuator, and a control mechanism. The swash plate is rotatable together with the drive shaft in a swash plate chamber. The conversion mechanism reciprocates the piston in a cylinder bore. The actuator is operative to change the inclination angle of the swash plate. The actuator is rotatable integrally with the drive shaft. The actuator includes a partitioning body, a movable body, and a control pressure chamber. The control mechanism changes the pressure of the control pressure chamber to move the movable body. The movable body and the link mechanism are located at opposite sides of the swash plate.
