摘要： The dimension of a compressor is decreased, to facilitate the installation of the compressor in a limited space, by installing a relief valve (50) in such a manner that the relief valve (50) does not protrude from the outer peripheral surface of a closed housing (1) of a compressor, in which a compression mechanism, incorporated in a closed housing, is driven by an external drive source via an electromagnetic clutch.The means for achieving the above object is to assemble the relief valve (50) to the closed housing (1) in such a manner that the relief valve (50) does not protrude from the outer peripheral surface of the housing (1) in order to discharge gas to the outside when the gas pressure in the closed housing (1) increases abnormally.

摘要： An oil pump for a closed type compressor of the present invention is mounted in the inside bottom of a closed housing. In the oil pump, a rotor is driven to revolve by an eccentric shaft formed at the lower end of a rotary shaft for driving a compressing mechanism while the rotor is formed with a projection which is inserted into a slot of a cylinder chamber in order to inhibit the rotation of the rotor. In this arrangement, the root of the projection is cut away so that the projection is prevented from interfering with angled portions of an opening of the slot.

摘要： A scroll fluid machine has a stationary scroll having a first end plate and a first spiral wrap projecting from one side of the first end plate. The first spiral wrap has a tip end. A swivel scroll has a second end plate and a second spiral wrap that projects from the one side of the second end plate. The second spiral wrap has a second end tip, and the first and second spiral wraps are engaged with each other. A first thin steel plate is provided on one side of the end plate between the first end plate and the second tip end. A first thin steel plate has a surface side that faces the second tip end. Further, a second thin steel plate is on one side of the second end plate between the second end plate and the first tip end. The second thin steel plate has a surface side that faces the first tip end. Both of the first and second thin steel plates are provided with conformable layers on the surfaces facing the tip ends. The conformable layers comprise a material that is softer than the first and second tip ends so that during operation a gap between the center portion of the tip ends and the opposite scroll end plate does not become too large. A leakage passage is provided in at least one of the thin plates so as to interconnect a central compression chamber formed by the spiral wraps and the outer circumferential chambers.

摘要： A scroll machine has a sealed housing divided into a high-pressure side and a low-pressure side by a discharge cover, a stationary scroll and a swivel scroll housing within the low-pressure side of the sealed housing, a frame with legs fixed within the sealed housing, a support spring through which the stationary scroll is attached to the top ends of the legs of the frame, and an intermediate pressure chamber formed by sealingly engaged parts of the rear portion of the stationary scroll and an inner surface of the discharge cover so that the stationary scroll will be pressed against the swivel scroll by hydraulic pressure introduced into the intermediate pressure chamber. The frame is plug-welded to the sealed housing at a plurality of points lying along the outer circumferences of the legs of the frame, the top ends of the legs of the frame are connected to each other with a reinforcing plate or the legs are fitted to the inner surface of the housing, so as to prevent lateral displacement of the stationary scroll and the breakage of sealing members at the parts defining the intermediate pressure chamber.

摘要： In a scroll type machine, such as a scroll compressor, the difference in level between the axial end surface of a wear-resistant plate (40) installed at the periphery of the end plate (17) of an orbiting scroll (16) and the axial end surface of the end plate (17) is set within 0.+-.10 .mu.m. This difference in level (.delta.) is set to this range to prevent wear of the wear-resistant plate and the end plate of the orbiting scroll and to prevent deterioration in the performance of the scroll-type compressor so that a scroll-type compressor with high performance and high reliability can be realized.

摘要： A scroll-type fluid machine in which the high-pressure chamber side (36) of a back pressure chamber (6a) using a fixed scroll (11) made of an aluminum base material can be fully sealed. The fixed scroll (11) is made of an aluminum base material, and a discharge cover (2) is made of a ferrous material. Between the U seals (35) interposed between the high-pressure chamber (36) side of the back pressure chamber (6a) and the low-pressure side, at least the U seal (35a) on the high-pressure chamber (36) side is made of glass-reinforced polytetrafluoroethylene resin, and is installed so as to be pressed against the fixed scroll (11). The U seal withstands a high temperature and large pressure difference and is installed so that the sliding mating part of the U seal (35a) is not the fixed scroll (11) made of an aluminum base material which is easily worn, but the discharge cover (2) made of a ferrous material which is less prone to wear.
