摘要:
A variable capacity type compressor has a swash plate (16), pistons reciprocating in the cylinder bores, a suction chamber (7a), and a discharge chamber (7b) with a check valve (33) downstream. The check valve (33) has a valve element (72) arranged in the case (71) for cooperation with the valve seat (70). The case (71) has a flow passage through the communication hole (71b) to the outside circuit. An annular groove is formed in the outer peripheral surface (72f) of the valve element (72) to allow the flow of leaking gas from the clearance between valve element (72) and valve housing to the exterior.
摘要:
A fluid machine, in which the step of mounting a filter on a flow passageway can be easily automated and the latitude of filter arrangement is improved, is disclosed. A mounting recess is formed on the inner bottom surface of a rear housing. An inlet to a gas feed passageway opens to the bottom of the mounting recess. A control valve for adjusting the displacement of the compressor is arranged on the way of the gas feed passageway. A filter including a support ring and a filter member made of a woven wire in a shape of a cylinder with one end covered is fixedly secured in the mounting recess by press fitting. The head of the filter member is formed to project beyond the inner bottom surface when the filter is mounted in the mounting recess.
摘要:
The seizure resistance of an Al-based flame-sprayed layer formed on the swash plate of a swash-plate type compressor is increased to such a level comparable to that of a flame-sprayed bronze layer. The Al-based flame-sprayed layer of the present invention contains: from 12 to 60% of Si and granular Si particles dispersed in the matrix thereof, and at least one dispersing phase of graphite carbon, amorphous carbon and carbon, the crystallizing degree of which is between the graphite carbon and amorphous carbon, and MoS 2 .

Mounting a filter on a flow passageway of a variable displacement refrigerant compressor can be easily automated. A mounting recess is formed on the inner bottom surface of a rear housing. An inlet to a gas inlet passageway (31) opens to the bottom of the mounting recess (72). A control valve (32) for adjusting the displacement of the compressor is arranged on the way of the gas inlet passageway. A filter (71) including a support ring (74) and a filter member (73) made of a woven wire in a shape of a cylinder with one end covered is fixedly secured in the mounting recess by press fitting. The head of the filter member (73b) is formed to project beyond the inner bottom surface (13c) when the filter is mounted in the mounting recess.
摘要:
A variable capacity type compressor has a swash plate (16), pistons reciprocating in the cylinder bores, a suction chamber (7a), and a discharge chamber (7b) with a check valve (33) downstream. The check valve (33) has a valve element (72) arranged in the case (71) for cooperation with the valve seat (70). The case (71) flow passage through the communication hole (71b) to the outside circuit. The communication hole (71b) is shaped in a triangular shape so that its opening area is smaller than that of a communication hole of a check valve opening area is proportional to a valve lift.
