A part of the auxiliary oil reservoir chamber is defined by a peripheral wall of the oil separation chamber. An introducing passage for introducing lubricant oil in the oil separation chamber to the auxiliary oil reservoir chamber is formed in the peripheral wall. The inlet of the introducing passage opens to the oil separation chamber on the inner surface of the peripheral wall. The outlet of the introducing passage opens to the auxiliary oil reservoir chamber. The main oil reservoir chamber is located below the auxiliary oil reservoir chamber in the direction of gravity. A drain port for draining lubricant oil in the auxiliary oil reservoir chamber to the main oil reservoir chamber is formed in a bottom wall of the auxiliary oil reservoir chamber.

摘要： A compressor compressing a fluid including lubricating oil includes, on the discharge side thereof, a first separation chamber for separating the lubricating oil by generating a swirling flow in the fluid. The first separation chamber includes: a circumferential wall; an inflow port that is formed in the circumferential wall and causes the fluid to flow into the first separation chamber; and a guiding plate extending from the circumferential wall. The guiding plate extends so as to face the inflow port in a direction where the fluid flows from the inflow port into the first separation chamber, and so as to deflect the fluid flow from the inflow port to guide it along an inner circumferential surface of the circumferential wall.

摘要： A mechanism for drawing in refrigerant to front compression chambers (28a) of a double-headed piston type compressor differs from a mechanism for drawing in refrigerant to rear compression chambers (29a). More specifically, the mechanism for drawing in refrigerant to the front compression chambers (28a) include suction valves (18a) configured by flap valves. The mechanism for drawing in refrigerant to the rear compression chambers (29a) is configured by a rotary valve (35). Thus, pulsation of the compressor is reduced, so that the generation of noise is suppressed. As a result, a quiet compressor is achieved.

摘要： A lubricating structure in a fixed displacement piston type compressor has a housing, a rotary shaft, a cam, a piston, a rotary valve and a rotary body. The housing defines a cam chamber, cylinder bores and a suction pressure region. The rotary shaft is rotatably supported by the housing. The cam is located in the cam chamber and is connected to the rotary shaft. The piston is located in each of the cylinder bores and engages the cam to reciprocate with rotation of the rotary shaft through the cam. The rotary valve connected to the rotary shaft includes an introducing passage and a supply passage that interconnects the introducing passage and the suction pressure region. The introducing passage introduces fluid into the cylinder bores through the supply passage. The rotary body connected to the rotary shaft includes a communication passage that interconnects the cam chamber and the suction pressure region.

摘要： A fluid filled type vibration damping device includes a first mounting member, a second mounting member, a main rubber elastic body, a flexible film, a partition member, a valve, a coil, a control-signals-generating circuit and a power amplifier circuit. The valve enables to switch the second orifice passage between an open state and a closed state. The second orifice passage communicates the pressure-receiving chamber and the equilibrium chamber with each other. The switch of the valve is performed by an electromagnetic force occurring by an electrical connection of the coil. Furthermore the control-signals-generating circuit is formed and disposed separately from the coil. The control-signals-generating circuit produces state switching control signals of the valve. Moreover the power amplifier circuit which supplies an electric-current to the coil by amplifying the state switching control signals, constitutes an actuator unit attached integrally to the coil, and is disposed separately from the control-signals-generating circuit.
