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 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 through the flange. A pin is supported in each support hole. The ends of each pin are received in guide holes. 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： 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： 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： 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.

摘要： A control valve for controlling displacement of a variable displacement compressor having a suction chamber, a discharge chamber, a control chamber, and a pressurizing passage. The control valve adjusts the amount of refrigerant sent to the control chamber from the discharge chamber to control the compressor displacement. The control valve includes a valve body for adjusting the opened area of the pressurizing passage. A solenoid urges the valve body in a first direction with a force corresponding to the value of the current fed to the solenoid. A first and second pressure chamber are partitioned by a diaphragm in the valve. A target value of the pressure difference between the first and second pressure chambers is determined by the urging force of the solenoid. For a given constant solenoid current, the compressor seeks the target value that corresponds to that current. The solenoid requires only a relatively small current range, even if carbon dioxide is used as the refrigerant. Also, the valve minimizes the compressor displacement when it receives no current.
