摘要： In a displacement type fluid machine wherein a space is formed by the inner wall surface of a cylinder and the outer wall surface of a displacer when the center of the cylinder is located on the center of the displacer, and a plurality of working chambers is formed when the positional relationship between the displacer and cylinder is for a gyration, the wear is reduced between the cylinder and displacer. Sliding portions between the displacer 5 and a cylinder 4 are fed with a lubricating oil 12 by forming an oil-feeding groove 5c in the surface of the displacer 5 so as to extend from the central portion of the displacer 5 to the vicinity of a suction port 7a, and feeding the lubricating oil 12 from the central portion of the displacer 5, so that the wear can be reduced.

摘要： A horizontal type rotary compressor including a compression element having a cylinder, a shaft having a crank thereon, a pair of side plates concurrently serving both as bearings of the shaft and as side walls of the cylinder, a roller fitted onto the crank, and a vane so arranged as to slide in a groove of the cylinder and have a tip end thereof contacted with the roller rotating in accordance with the rotation of the crank and an appropriate end thereof urged by a spring to make a reciprocating movement along the groove are provided within a case. A pumping chamber is defined by a rear face of the vane, the groove of the cylinder and the side plates. One of the side plates is formed with a suction port capable of sucking thereinto the oil within the case while the other of the side plate is formed with a discharge port for transmitting the oil in the pumping chamber to an oil feeding passage. An oil feeder means for use in the horizontal type rotary compressor is a space provided at the exit of the suction port of the side plate having the suction port and the suction port opens downwardly so that the feeding of a sufficient or stable amount of oil is ensured even when the surface level of the oil is lowered.

摘要： A horizontal compressor including an electric motor and a compressor element mounted in a case serving concurrently as an oil sump. The compressor element includes a cylinder, a shaft having a crank, a roller fitted to the crank for eccentric rotation along inner side surfaces of the cylinder, a vane moving in reciprocatory movement in a bore of the cylinder while abutting against the roller, two side plates located on opposite sides of the cylinder, one of the two side plates being formed with a suction port for a lubricant and the other side plate being formed with a discharge port for the lubricant, and a pump chamber defined by a back of the vane, the bore of the cylinder and the two side plates. The suction port is in the form of a tapering port including a small diameter portion directly adjacent the pump chamber and a large diameter portion directly adjacent the case; the discharge port is in the form of a tapering port including a small diameter portion directly adjacent the lubricant feed passage and a large diameter portion directly adjacent the pump chamber; and a space is provided at least to the suction port in a position in which the space is in communication with the small diameter portion of the suction port.

摘要： A horizontal type rotary compressor comprising radial partitioning walls in a discharge silencer. A slant portion is formed in the partitioning walls thereby enabling the oil within the discharge silencer to be discharged to the outside of the silencer. Thus, a noise generation due to a cavity resonance in the discharge silencer and an impact noise of a discharge valve in the oil may be prevented. At the same time, a carbonization of the oil, caused by an increase of the oil temperature, may also be prevented.
