摘要： In a variable displacement type gear pump, each of a main gear pump portion and a sub gear pump portion has a drive gear, a driven gear engaging with the drive gear, and an urging portion applying radial load to the drive and driven gears. A bypass passage returns fluid in a discharge-side space of the sub gear pump portion to a suction passage. An opening and closing valve opens the bypass passage in a small displacement operational state. A drive shaft supports the main drive gear and the sub drive gear. A driven shaft supports the main driven gear and the sub driven gear. The drive gears and the driven gears are rotated in accordance with a rotation of the drive shaft. The drive and driven shafts transmit the radial load in the main gear pump portion to the sub gear pump portion in the small displacement operational state.

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： A motor-driven compressor performs suction, compression, and discharge of refrigerant. The compressor has four cylinder bores and four pistons. A swash plate is integrally rotated with a drive shaft. A transmission mechanism transmits rotation of the swash plate to the pistons. The ratio of the discharge pressure to the suction pressure when the discharge displacement of the compressor is maximum, that is, the compression ratio, is in a range of 2 to 4.5. The compressor is constructed to permit the size of the motor to be minimized.

摘要： An improved scroll compressor having a movable scroll that orbits without being inclined. The compressor has a fixed scroll formed in the housing. The movable scroll is accommodated in the housing and mates with the fixed scroll. The movable scroll is driven by a drive shaft via a crank mechanism. A flange is formed at the periphery of the movable scroll and lies perpendicular to the drive shaft. A groove is formed in the housing. The groove is slightly wider than the thickness of the flange. The flange is slidably accommodated in the groove. Support holes extend in the housing. A pin is supported in each support hole. The ends of each pin are received in guide holes through the flange. Since engagement of the flange and the groove prevents the movable scroll from being inclined, the pin is maintained parallel to the guide holes and follows the wall of the guide holes. As a result, uneven wear of the pins and the guide holes is avoided.
摘要翻译：一种改进的涡旋压缩机，其具有可旋转而不倾斜的可动涡旋件。压缩机具有形成在壳体中的固定涡旋盘。动涡旋盘容纳在壳体中并与固定涡旋件配合。动涡旋盘通过曲柄机构由驱动轴驱动。法兰形成在可动涡旋件的周边并垂直于驱动轴。在壳体中形成凹槽。凹槽比凸缘的厚度略宽。凸缘可滑动地容纳在槽中。支撑孔延伸到外壳中。每个支撑孔支撑销。每个销的端部通过法兰被接收在引导孔中。由于凸缘和凹槽的接合防止可动涡旋件倾斜，所以销保持平行于导向孔并跟随引导孔的壁。结果，避免了销和引导孔的不均匀磨损。

摘要： A wave cam is rotatably and integrally mounted on a drive shaft of a compressor. Pistons are connected to cam surfaces of the wave cam via shoes. The shoes move relatively to the cam surface along a predetermined orbital path. The predetermined orbital path defined on the cam surfaces is ground by bringing a grinding surface of a grinding stone, attached to a rotary shaft, into contact with the cam surfaces. During grinding, the grinding surface is perpendicular in respect with the cam surface. The axis of the grinding stone coincides with the axis of the rotary shaft.

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.
