摘要： A scroll-type fluid machine in which: a fixed scroll and a moveable scroll are disposed in a housing; a fluid pocket, the volume of which varies, is formed between the fixed scroll and the moveable scroll; and a thrust plate for receiving the reaction force in the axial direction of pressure applied within the fluid pocket is disposed between the bottom plate of the moveable scroll and the housing. The scroll-type fluid machine is characterized in that at least the surface of the thrust plate facing the bottom plate of the moveable scroll is subjected to tin plating. As a consequence, it is possible to efficiently produce, at a low cost, a thrust bearing which is disposed between the bottom plate of the moveable scroll and the housing, exerts excellent seizure resistance, and has a high PV limit level and a low friction coefficient.

摘要： A rotary vane compressor comprises a cylinder having two closed ends defining a cylinder chamber in which is rotatably mounted a rotor. The rotor carries a plurality of radially movable vanes which move radially into sliding contact with the inner surface of the cylinder chamber during rotation of the rotor to compress a refrigerant gas. The rotor is rotationally driven by a rotor shaft rotatably mounted by bearings in the cylinder ends. To prevent destruction of the ozone layer, a refrigerant containing no chlorine, such as HFC-134a (1,1,1,2-tetrafluoroethane; CH.sub.2 FCF.sub.3) is used, and to compensate for the inferior lubricating properties of the chlorine-free refrigerant, the bearings are provided with a manganese phosphate coating of 10 .mu.m-15 .mu.m thickness to prevent cohesion and seizure of the mutually contacting surfaces of the bearings and rotor shaft.

摘要： There is provided an idling engine speed control apparatus which can economically and suitably control an idling engine speed in the case where a variable displacement type compressor with a variable displacement is mounted is a part of an automotive air conditioning system. A the time of idling, a duty ratio of a control valve current value sent as an external signal to a control valve is sent also to an engine controller, and the engine control apparatus controls the output of an engine on the basis of the duty ratio. For example, when the duty ratio becomes high from a small value, since the present operating state of the compressor is in the direction where the differential pressure becomes high and the displacement is increased, it is expected that a large load is applied to the engine. Thus, in this case, the engine output is controlled correspondingly to a large duty ratio and the idling engine speed is made high.

摘要： A gas compressor has a first chamber for receiving a low pressure refrigerant gas. A main body has a second chamber for drawing in the low pressure refrigerant gas from the first chamber and undergoing a compression operation to compress the low pressure refrigerant gas into a high pressure refrigerant gas. A third chamber receives the high pressure refrigerant gas from the second chamber. A fourth chamber receives a lubricating oil and is subjected to the pressure of the high pressure refrigerant gas from the third chamber. An oil passage has an inlet port opening into the fourth chamber and an outlet port opening into the main body. The lubricating oil from the fourth chamber is supplied to the main body through the oil passage due to a pressure difference between the third chamber and one of the first chamber and the second chamber. A pressure difference eliminating device releases the high pressure refrigerant gas from the third chamber to the first chamber upon stoppage of the compression operation in the second chamber to thereby eliminate the pressure difference between the third chamber and one of the first chamber and the second chamber.
