摘要： A piston type compressor has a housing, a crank chamber and a drive shaft supported by the housing. A front restriction and a rear restriction are located in the housing. The front and rear restrictions restrict axial movement of the drive shaft. The front restriction restricts forward movement of the drive shaft. The rear restriction restricts rearward axial movement of the drive shaft. A first clearance is located between the rear end of the drive shaft and the rear restriction when the drive shaft is restricted by the front restriction. A second clearance is formed between the piston and a valve plate when the drive shaft is restricted by the front restriction and when the piston is in the top dead center position. The first clearance is narrower than the second clearance. The method of assembly the piston easily sets the first clearance.

摘要： A compressor has a front housing, cylinder block and a rear housing. The housings and cylinder block are secured to one another by a plurality of bolts. A plurality of pistons reciprocally move in cylinder bores to compress gas. Each of said bolts has a shaft extending through the housings and the cylinder block. A cam plate is supported on a drive shaft for integral rotation therewith to convert the rotation of the drive shaft to reciprocal movement of a piston in the cylinder bore. The piston rotates about its axis in accordance with rotation force transmitted from the cam plate and abuts against the shaft of the bolt, which extends in close proximity to the piston. The rotating piston abuts against the shaft so that the rotation thereof is restricted. The shaft has a diameter greater than that of a threaded portion formed at an end of the bolt. Since the threaded portion is smaller, the threaded portion does no damage to the piston during assembly.

摘要： A compressor includes pistons slidably accommodated in cylinder bores. A head and a skirt are formed at the ends of the piston. The head has a peripheral surface that always contacts the inner surface of the cylinder bore. The skirt is coupled with a swash plate. An annular space opens to the side of the piston. The annular space is located between the head and the skirt. A recess is located on the inner wall of a front housing and extends longitudinally in the axial direction of the piston. A projection is integrally formed on the skirt of the piston to engage with the recess. Rotation of the piston about its axis with respect to the cylinder bore is restricted by the engagement of the projection with the recess. A force acting on the piston in a direction transverse to the axis of the piston is received by the recess through the projection.

摘要： A compressor having a cylinder bores and pistons are disclosed. Each piston moves in the associated cylinder to compress gas therein. Each piston slides on an inner peripheral wall of an associated cylinder to seal a compression chamber. Each piston includes an outer peripheral surface and cavities. The outer peripheral surface has a seal to seal the cylinder and a pressure receiving surface to receive reaction forces from the wall of the cylinder. A low friction layer is formed on the pressure receiving surface. The layer facilitates the sliding movement of the piston with respect to the cylinder.

摘要： A method for machining a variable displacement compressor piston. The piston is connected to a swash plate by a pair of semi-spherical shoes. One end of the piston has a slot for receiving the swash plate. The slot includes a pair of opposed walls. Each wall has a concave spherical recess for supporting one of the shoes. When forming the recesses, a tool having an asymmetrical spherical cutter is placed between the slot walls in the piston. Then, the piston is rotated about a machining axis that is perpendicular to the axis of the piston and intersects the midpoint between the walls. Then, the tool is moved such that the center of the cutter is located on the rotation axis of the piston. This forms the recesses on the walls such that the recesses conform to a single sphere, the center of which is located on the axis of the piston.
