摘要： A compressor has a plurality of cylinder bores defined around a rotary shaft in a cylinder block and a plurality of double-headed pistons accommodated in the respective cylinder bores. The pistons compress refrigerant gas in a plurality of front and rear compression chambers defined in the bores in the front and rear of the respective pistons according to the rotation of a cam plate mounted on the rotary shaft. The compressor has bearing that receive thrust loads applied to the rotary shaft during operation of the compressor. The pistons create a net thrust load determined by the difference between the maximum of the sum of loads applied to the front sides of the pistons by the refrigerant gas in the front compression chambers and the maximum of the sum of loads applied to the rear sides of the pistons by the refrigerant gas in the rear compression chambers. The pistons transfer the net thrust load to the rotary shaft in a predetermined direction.

摘要： A reciprocating compressor includes double headed pistons forming front and rear sets of compression chambers on either side thereof and a pair of tapered rotary valves arranged for introducing a coolant gas into the compression chambers. The valves are urged into contact with valve chambers by springs and a drive shaft is urged in one axial direction by a prestress mechanism. The valve urging force for one rotary valve is different from the valve urging force for the other rotary valve, so that the rotary valves operate at different times and over different distances and the movements of the rotary valves are controlled to move the drive shaft in the same axial direction as the direction of the prestress mechanism.

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： In a variable displacement compressor that draws, compresses, and discharges refrigerant gas, the displacement is adjusted by varying the inclination of a cam plate in accordance with the difference between the pressure in a crank chamber and the pressure in cylinder bores. A pressurizing passage connects the crank chamber to a discharge passage. A bleed passage connects the crank chamber to a suction chamber. A displacement control valve is externally controlled and varies the pressure in the crank chamber by adjusting the opening size of either the pressurizing passage or the bleed passage. A suction control valve closes a duct between the suction chamber and an evaporator when the pressure in the crank chamber exceeds a predetermined level to prevent an excessively high pressure in the crank chamber.
