    摘要: A swash plate (15) of a swash plate type compressor includes a slide-contact film (32, 33) having a metal layer, which is formed on a slide-contact surface (152, 153), which slide-contacts shoes (18), through sintering, and a resin layer (322, 332), which is formed on the metal layer. By using the metal layer, which is formed through sintering, the bonding of the resin layer and the metal layer is guaranteed, deficiencies such as cracking of a slide film and seizure are prevented, and the slide-contact characteristic relative to the shoes is improved.

    摘要: An air conditioning system 100 may include a compressor 101 having a driving chamber 110, a cooling circuit 151, a heating circuit 152 and capacity controllers 301, 401. The compressor 101 may have a suction port 115, a discharge port 120, a driving unit 130 provided within the driving chamber 110. The driving unit 130 decreases compressor output discharge capacity when pressure within the driving chamber 110 increases. The first capacity controller 301 and the second capacity controller 401 are provided in series onto the capacity control passage 321, 323, 421. The first capacity controller 301 opens the capacity control passage 321, 323 when compressor suction pressure Ps results predetermined low-pressure state during operation of the cooling circuit 151 and the second capacity controller 401 opens the capacity control passage 323, 421 during operation of the cooling circuit. As the result, the heat exchanger 159 in the cooling circuit 151 is prevented from being frosted. The first capacity controller 301 opens the capacity control passage 321, 323 during operation of the heating circuit 152 and the second capacity controller 401 opens the capacity control passage 323, 421 when compressor discharge pressure Pd results predetermined high-pressure state during operation of the heating circuit 152. As the result, the heating circuit 152 is prevented from being damaged by an abnormally high discharge pressure.

    摘要: The present invention provides a piston type compressor in which vibration and noise due to interference between the piston and the cam plate can be suppressed by preventing the rotation of the piston, and at the same time, it is possible to improve the productivity and accomplish the cost down. According to the present invention, the piston type compressor comprises a housing including a crank chamber and a cylinder block. A cylinder bore is formed in the cylinder block. A piston is accommodated in the cylinder bore so as to reciprocate. The piston is operatively connected to the cam plate. The piston reciprocates accompanying with rotation of the drive shaft so that drawing and discharging of a refrigerant is performed. A rotation preventing portion is formed on the piston, and a groove facing the rotation preventing portion so as to have clearance is formed on an inner circumferential surface of the crank chamber. By means of the abutment of the rotation preventing position with the groove, the rotation of the piston is prevented. The groove is formed to have draft smaller than that of other portions in the casting forming process.

    摘要: A lip seal comprises an elastomer lip member (12) having its rear supported with a pressure resisting back-up ring (13), and a synthetic resin lip member (14) arranged on a rear side of the elastomer lip (12). On the inner circumferential surface of the seal lip portion (124) of the elastomer lip member (12), helical grooves (125) generating a pumping action of a fluid introducing direction from an inner space (S1) of machine side when a shaft (2) rotates are formed. When a pressure in the inner space (S1) of machine is 1 MPa, by making a contact width between the seal lip portion (124) of the elastomer lip member (12) and a shaft (2) at least 0.6 mm, so that a surface pressure maximum portion of the seal lip portion (124) of the elastomer lip member (12) to the shaft (2) is biased or maldistributed toward its rear side, whereby a fluid introdution by said helical grooves (125) is performed satisfactorily (Fig. 1).

    摘要: According to the structure for damping the pulsations of discharge pressure of a compressor of the present invention, in the annular discharge chamber 28 divided on the outer circumferential side in the rear housing 5, two bulkhead sections 35 are extended from positions on both sides of the outlet 23 in the circumferential direction in such a manner that they are separate from each other. The end portion of each bulkhead section 35 is extended to halfway between the first discharge port section 20 and the second discharge port section 21. The flow path from the first discharge port section 20 to the outlet 23 is directed to the opposite side to the outlet 23 and then turned back to the outlet 23. Therefore, the length of the flow path from the first discharge port section 20 to the outlet 23 becomes relatively long.

    摘要: A torque limiting mechanism for transmitting power from an external drive source (Eg) to the drive shat (17) of a compressor (C). A pulley (33), which is coupled to the external drive source, has elastic members (44). A hub, which is attached to the drive shaft, has engaging portions (41). A coupler member (59) is located between the pulley (33) and the hub (38). The coupler member is engaged with the elastic members (44) and with the engaging portions (41) such that power is transmitted from the pulley to the hub. The urging members urge the coupler member (59) such that the coupler member is disengaged from the engaging portions (41). When power is transmitted from the pulley to the hub, the elastic members (44) maintain the coupler member (59) engaged with the elastic members (44) and with the engaging portions (41). When load generated due to power transmission exceeds a predetermined level, the elastic members (44) are deformed such that the coupler member (59) is disengaged from the elastic members (44). When disengaged from the elastic members (44), the coupler member is disengaged from the engaging portions (44).
