Abstract: In a manufacturing method of a valve plate for a compressor according to this invention, a punch die 43 formed with a convex and concave configuration at its tip end face 42 is set at a press machine 41, and the punch die 43 is depressed against a surface of a valve plate 9 to transfer the convex and concave configuration of the tip end face 42. Thus, peripheral portions of a suction port and a discharge port of the valve plate 9 are roughened.

Abstract: A refrigeration suction mechanism used in a piston type compressor. The compressor comprises a rotary shaft, a plurality of pistons, a compression chamber and a rotary valve. The pistons are arranged in a circumference of the rotary shaft to reciprocate in conjunction with a rotating motion of the rotary shaft through a cam member. An end surface of one of said pistons reciprocates in the compression chamber. The rotary valve includes an introducing passage which allows refrigerant to flow into the compression mechanism through an end opened on an outer surface of the rotary valve. The refrigeration suction mechanism comprises a suction passage and a reactive force transmitting mechanism. The suction passage communicates with the cylinder bore and intermittently communicates with the end of the introducing passage in conjunction with a rotating motion of the rotary valve.

Abstract: Variable displacement compressors 30 may include a rotor 7 that is press-formed from a plate W. The rotor 7 is fixedly mounted on a drive shaft 6 and is coupled to a swash plate 8 via a hinge device 20. The hinge device 20 preferably permits the swash plate 8 to rotate with the rotor 7 as well as the drive shaft 6 and also may permit the swash plate 8 to change its inclination angle relative to the rotor 7 as well as the drive shaft 6. The swash plate 8 may be coupled to a piston(s) 11 that reciprocates within a cylinder bore(s) 2a.

Abstract: A power transmission mechanism for power-transmittably coupling a rotating unit of a compressor (11) composed of a drive shaft (17), a rotating support (23) and a swash plate (27) with an engine (62), comprising a pulley (56) and an armature (58), both of which constitute a first rotating body provided on a side of the engine, a hub (57), which serves as a second rotating body coupled to the drive shaft of the compressor, and a helical spring (64), couples the first and second rotating bodies. The use of the helical spring can easily set a resonant frequency of a power transmission system outside a frequency band for troque variation produced on a side of the compressor or the engine. As a result, it becomes possible to suppress resonance of the power transmission system to prevent generation of noises and damage to the internal mechanism of the compressor.

Abstract: Variable displacement compressor may include a swash plate inclinably coupled to a drive shaft. A piston may be disposed within a cylinder bore and an end portion of the piston may be connected to a peripheral edge of the swash plate by a shoe. The piston preferably reciprocates within the cylinder bore in order to compress a refrigerant in response to rotation of the inclined swash plate. The inclination angle of the swash plate can be changed to change the compressor output discharge capacity. A rotor is preferably coupled to the drive shaft so that the rotor rotates together with the rotating drive shaft. A hinge mechanism connects the swash plate with the rotor by means of a guide on a rotary disk of the rotor. The hinge mechanism transmits torque from the drive shaft to the swash plate regardless of the inclination angle of the swash plate.

Abstract: A drive power transmission apparatus including a torsionally deformable spring capable of being torsionally deformed so as to permit a relative rotation between a rotor element and a drive shaft in response to a change in a load torque appearing in a drive-power-receiving unit, a releasing element operable to move the free outer end of the torsionally deformable spring from the power transmitting face of the rotor element when the relative rotation between the rotor element and the drive shaft increases due to an increase in the load torque beyond a predetermined limiting torque, and a mechanical elevation arranged in the rotor element for permitting the free outer end of the torsionally deformable spring to ride thereon to thereby promote separation of the spiral spring from the rotor element in order to interrupt the transmission of drive power.
