摘要： A shaft sealing assembly is located in a suction chamber of a swash plate type compressor to seal the space between a drive shaft and a housing. A first end portion of the drive shaft is supported by a first radial bearing. A second end portion of the drive shaft is supported by a second radial bearing. The suction chamber is closer to the first end portion of the drive shaft than the first radial bearing is. An axial passage is formed in the drive shaft to connect the suction chamber to the crank chamber. An inlet of the axial passage is closer to the second end portion than the second radial bearing is. An outlet of the axial passage is closer to the second end portion than the first radial bearing is.

摘要： A compressor has a housing and a cylinder block. The housing includes suction and discharge chambers. The cylinder block is fixed to the housing via a valve plate assembly. The valve plate assembly forms suction and discharge ports and suction and discharge valves. A partition wall is formed with the housing, and separates the suction chamber and the discharge chamber. The housing includes a first surface, and the cylinder block includes a second surface. At least one of the first and second surfaces is concave in shape. The cylinder block is screwed to the housing at the partition wall or a position closer to the central axis of the housing than the partition wall by a bolt so that the first surface faces the second surface.

摘要： A torque limiter to be operatively coupled to an engine is secured to the outer periphery of a driving shaft through screwing-engagement. The driving shaft and the torque limiter are screw-engaged and fixed to each other so that the torque limiter is pushed or urged against a seating face formed at the outer periphery of the driving shaft. The seating face abuts against the torque limiter restricting the screwing-movement of the driving shaft. Rotation force is transmitted between the driving shaft and the torque limiter via the seating face. A cylindrical member is disposed between the torque limiter and the seating face of the driving shaft. The cylindrical member is press-fitted and fixed to the outer periphery of the driving shaft, so that the power transmission between the driving shaft and the torque limiter is also performed through the press-fit portion between the cylindrical member and the driving shaft.

摘要： A seal is provided between the housing assembly of a variable displacement compressor and a rotary shaft to seal inside the housing assembly. The seal is retained in a retaining chamber, which is separated from a suction chamber and a control pressure chamber. A refrigerant passage is connected to the retaining chamber to feed a refrigerant to the retaining chamber to cause the refrigerant to contact the seal. The refrigerant passage includes a path extending from outside the housing assembly to the suction chamber through the retaining chamber. A restriction ring having a restriction function guides the refrigerant from the control pressure chamber to the retaining chamber and releases an internal pressure of the control pressure chamber.

摘要： The deformation of cylinder bores in a cylinder block is prevented. The cylinder block 19 is inserted into a front housing 11. The cylinder block 19 is fixed to the front housing 11 by tightening plural screws 38 which penetrate through the cylinder block 19, from an end surface 191 side thereof, to be screwed into an end wall 32 of the front housing 11. Plural deformation absorbing grooves 39 are provided on the end surface 191. Each one of the deformation absorbing grooves 39 is provided in each intermediate space between the adjacent paired cylinder bores 41.

摘要： A gasket 36 is interposed between an end face 341 of a front housing 11 and an end face 351 of a rear housing 12. A coned disc spring 37 is interposed between an end face 192 of a cylinder 19 and the end face 341 of the front housing 11. When the end faces 341, 351 are caused to approach each other so as to be joined together, the coned disc spring 37 is first held by the end face 341 of the front housing 11 and the end face 192 of the cylinder 19. When the end faces 341, 351 are caused to approach each other further so as to be joined together, the gasket 36 is held between the end faces 341, 351. Thus, it is ensured that the cylinder and the seal material interposed between the first housing and the second housing are held therebetween.

摘要： The compressor has a cooling structure to effectively cool a shaft seal device interposed between a housing of the compressor and a rotary shaft. The front housing has a through-hole through which the rotary shaft extends, and the shaft seal device is arranged in the through-hole. A passage (suction passage portion) is connected to the thorough-hole. An inlet from a portion of the passage to the through-hole is arranged right above the rotary shaft, and an outlet from the through-hole to a portion of the passage is arranged right below the rotary shaft. The passage is connected to a suction pressure region outside the compressor and to the suction chamber via the through-hole.

摘要： A piston compressor includes a front housing member and a rear housing member. A suction chamber and a discharge chamber are defined either in the front housing member or in the rear housing member. A cylinder block is accommodated in a space defined by the front housing member and the rear housing member to be isolated from ambient air. Cylinder bores are defined in the cylinder block. Pistons are accommodated in the cylinder bores. A drive shaft is connected to each piston and is supported by the cylinder block. The front housing member and the rear housing member are connected with each other, and the cylinder block is fixed to one of the housing members. The compressor is sealed in an improved manner.
