摘要： A swash plate type compressor includes a cylinder blocks having a crank case which communicates with a suction port and a plurality of bores formed therein. The ends of each bore are covered with a pair of housings. The bores communicate with discharge chambers. A drive shaft is rotatably placed within the cylinder blocks. A swash plate is rotatable in the crank case, and is mounted on the drive shaft. A plurality of pistons are drivably coupled to the swash plate, and are reciprocotable in their respective bores. As the pistons reciprocate, a refrigerant in the crank case is sucked into each bore and is compressed therein. The compressed refrigerant is discharged into the discharge chambers from the bores. A passage for transporting the refrigerant between the discharge chambers is formed along the axis of the drive shaft. Seals are provided between the cylinder blocks and the drive shaft for sealing the gap between the discharge chambers and the crank case.

摘要： A swash plate type compressor comprising a swash plate accommodated in a swash plate chamber. Front and rear housings are attached to the cylinder block to form suction chambers and discharge chambers, respectively. A refrigerating medium is introduced from a suction inlet to the suction chambers via the swash plate chamber and discharged from the discharge chambers. A drive shaft is fixed to the swash plate for reciprocally moving pistons. The drive shaft has a discharge passage in the form of an axial bore formed in the drive shaft for connecting the front discharge chamber to the rear discharge chamber. The discharge passage is thus isolated from the suction system.

摘要： A compressor comprises a cylinder block having cylinder bores formed radially spaced from and circumferentially distributed equidistantly about the cylinder longitudinal axis. Pistons are slidably received in the respective bores for reciprocation therein executing alternately suction and discharge strokes. The compressor also has a discharge valve assembly for controlling discharge of a compressed fluid from each of the bores into a discharge chamber, which assembly is axially movable between a first position in which the assembly is abutted against an end wall of the block and a second position in which the assembly is spaced from the end wall of the block to define a narrow space therebetween to interconnect the bores with each other. When the assembly is pushed toward the second position by the pressure of the compressed fluid during initial running of the compressor, bypass channels interconnect the cylinder with the discharge chamber.

摘要： A swash plate type compressor is provided with a front and rear cylinder blocks having a crank case connected to a suction port. The cylinder blocks include a plurality of cylinders, and are connected to a front and rear housing sections for covering the cylinders. Each housing section contains a discharge chamber. A drive shaft is rotatabley supported by the cylinder blocks. A swash plate is mounted on the drive shaft and is rotatably disposed within the crank case. Two-head pistons move within their respective cylinders in cooperation with the swash plate. The refrigerant is drawn into, and compressed in each cylinder. Thereafter, it is discharged into the external refrigerating circuit through the front and rear discharge chambers, and a final discharge port. A discharge passage includes a hollow primary passage which is provided within the drive shaft. The primary passage communicates with the front and rear discharge chambers. A groove is provided on an inner wall of the primary passage. As the drive shaft rotates, the groove separates the refrigerant from the lubricating oil mixed with the refrigerant. An oil passage is provided between the discharge chamber and the crank case. The separated oil flows from the discharge chamber to the crank case, through the oil passage, and is used again in lubricating the components of the compressor.

摘要： A wave cam 17 is rotatably supported by a drive shaft 13 in cylinder blocks 11, 12. Front and rear cam surfaces 17A, 17B of the wave cam 17 are defined by the surface of a predetermined imaginary cylindroid. Semi-spherical shoes 18, 19 are interposed between each cam surface 17A, 17B and each double-headed piston 16, which is accommodated in each cylinder bore 11a, 12a. Each shoe 18, 19 has a spherical surface 18a, 19a and a flat surface 18b, 19b. An imaginary circumference C0 corresponding to the arrangement of centers Q1, Q2 of the spherical surfaces 18a, 19a of the shoes 18, 19, respectively, is defined on each cam surface 17A, 17B. An imaginary circumference C1 corresponding to the arrangement of axes L1 of each cylinder bore 11a, 12a is also defined on each cam surface 17A, 17B. The center of both circumferences C0, C1 coincide with an axis L0 of the drive shaft 13. The radius R1 of the circumference C0 is larger than the radius of the circumference C1. Integral rotation of the drive shaft 13 and the wave cam 17 reciprocates each piston 16 in the cylinder bores 11a, 12a via the shoes. The centers Q1, Q2 of each spherical surface orbits outside of the circumference C1 on the associated cam surface 17A, 17B.

摘要： A wave cam type compressor includes cylinder blocks. A drive shaft is rotatably supported in the center cylinder blocks. A plurality of cylinder bores are defined about the drive shaft in the cylinder blocks. A wave cam, mounted on the drive shaft, comprises opposing cam surfaces. A width of second portions which move a piston to its bottom dead center position is more narrow than a width of first portions which move a piston to its top dead center position. The pistons are connected to the wave cam by way of shoes. The shoes move along a predetermined path on the cam surfaces. The shoes and the wave cam convert the integral rotation of the drive shaft and wave cam to a reciprocating movement of the pistons to compress fluid introduced into the cylinder bores.

摘要： A wave cam type compressor is described. Cylindroid blocks are provided to support a drive shaft and to contain a plurality of cylinder bores centered around the drive shaft. A wave cam attached to the drive shaft has cam surfaces on the front side and the rear side. The cam surfaces are composed of convex surfaces only. Pistons in the cylindroid blocks are operated by the wave cam through shoes. Each shoe has a spherical surface and a flat surface. The spherical surface is fitted in a recess formed on the piston, while the flat surface makes line contact with the cam surface of the wave cam. The shoes move relative to the wave cam on a predetermined circular path on the cam surfaces. The rotation of the wave cam together with the drive shaft is converted to reciprocating motions of the pistons in the cylinder bores with the aid of the shoes and wave cam, thus achieving compression of a fluid supplied to the cylinder bores.
