摘要： In a compressor that is configured to guide the lubricating oil separated from the discharged refrigerant by an oil separator to the radial bearing supporting the drive shaft, through an oil supply hole 29, a rotating member 30 that rotates together with said drive shaft is provided adjacent to the radial bearing on the drive shaft. Moreover, an outlet 29a of the oil supply hole 29 opens to the internal surface of a circular hole 31 that supports the rotating member 30. A channel 34 for restricting the flow rate comprises a gap defined between the rotating member 30 and the circular hole 31, and restricts the flow rate discharged front the oil supply hole 29 to the radial bearing, and at the same rime, the rotation of the rotating member 30 sweeps out foreign substances, such as sludge, from the outlet 29a of the oil supply hole 29.

摘要： An electric compressor includes a rotary shaft that is driven by an electric motor. The motor generates driving torque. Pistons compress gas in accordance with rotation of the rotary shaft. During one turn of the rotary shaft, the times when the net load torque generated by the pistons is minimum and the times when the driving torque of the motor is minimum occur at substantially the same rotation angles of the rotary shaft. Also, during one turn of the rotary shaft, the times when the net load torque is maximum and the times when the driving torque of the motor is maximum occur at substantially the same rotation angles of the rotary shaft. The driving torque is always greater than the net load torque. Therefore, the motor need not be large to generate sufficient torque.

摘要： An air conditioning apparatus for a vehicle that includes a multi-stage compressor, an internal heat exchanger, an external heat exchanger, a heat exchanger switching circuit, a cooling expansion passage and a heating expansion passage. The compressor has at least two cylinder bores, one bore being smaller than the other. Refrigerant is compressed in two stages. Refrigerant is conducted from the large cylinder bore to the small cylinder bore via an intermediate chamber. The heat exchanger switching circuit connects the intake chamber of the compressor to one of the heat exchangers depending on whether heating or cooling is desired.

摘要： A compressor including a compressing mechanism accommodated in a housing. The mechanism draws refrigerant from an intake chamber into a compression chamber and discharges the refrigerant from the compression chamber to the discharge chamber. A seal device prevents leakage of refrigerant from the internal space to the atmosphere between the drive shaft and the housing. An isolation chamber, which is separately formed in the housing, accommodates the seal device. A pressure reducing passage reduces the pressure of the isolation chamber to reduce the pressure difference applied to the seal device.

摘要： In a single-ended swash plate compressor, unbalanced thrust loads in either axial direction are reduced so that thrust loads acting on pistons in the direction of the front end are practically balanced by those in the direction of the rear end, for example, by connecting an intake chamber to a swash plate chamber by means of an adjustment valve to adjust the pressure in the swash plate chamber acting on the front end surfaces of the pistons to a suitable intermediate pressure by the action of the adjustment valve. In a single-ended swash plate compressor with pistons housed in both ends of a cylinder assembly comprising one set of pistons for guidance and another set for compression, discharge pressure is introduced into some of the cylinder bores housing guide pistons and intake pressure is introduced into the cylinder bores housing guide pistons into which discharge pressure is not introduced.

摘要： A variable displacement type gear pump has gear chambers, one of which is a specific gear chamber. A suction passage is formed in the housing so as to communicate with suction-side spaces. An outlet passage communicates with discharge-side spaces. A return passage returns the fluid discharged to the discharge-side space of the specific gear chamber to the suction passage. The return passage communicates with the suction passage at a confluence portion located upstream side of the suction-side space. An opening and closing valve opens the return passage in a small displacement operational state. A check valve is located between the discharge-side space of the specific gear chamber and the outlet passage for preventing the fluid discharged from the gear chamber other than the specific gear chamber from flowing into the discharge-side space of the specific gear chamber in the small displacement operational state.

摘要： Scroll compressors are taught that include an outer peripheral portion (23) of a movable scroll member (20) disposed opposite of an end face (13) of a stationary scroll member (10). At least one end portion (20, 23) has a shape that prevents contact when the movable scroll member (20) bends or deforms under high pressure. The contact avoiding shape or structure may be, for example, a tapered portion, a recessed portion or a step shaped portion.

摘要： A scroll-type compressor having a fixed scroll and a movable scroll. The fixed scroll includes a fixed base plate and a fixed volute wall extending from the fixed base plate. The movable scroll includes a movable base plate and a movable volute wall extending from the movable base plate. The movable volute wall has a distal end surface that faces the fixed base plate. A passage is formed through the movable volute wall and the movable base plate from the distal end surface. The passage reduces the area of the distal end surface of the movable volute wall, on which pressure is applied. This reduces the thrust load applied to the movable scroll and makes the compressor more reliable.

摘要： A scroll-type compressor has a front housing, a stationary scroll, and a rear housing arranged in this order. A movable scroll is arranged in a space formed in the front housing and the stationary scroll and opposed to the stationary scroll so that the movable spiral wall engages with the stationary spiral wall. A rotatable shaft is supported by the rear housing and extends through the stationary scroll base plate toward the movable scroll. An orbital rotating mechanism is arranged at the end of the rotatable shaft to cause the movable scroll to orbitally rotate. The orbital rotating mechanism and the rotatable shaft are arranged on the side of the movable spiral wall with respect to the movable scroll base plate.
