摘要： A scroll member has a scroll wall having an axial end having a transverse surface on which a groove 20 is cut along the spiral direction of the scroll wall, to which groove a seal member contacting a facing scroll member is received. The scroll wall has a radially inner portion having a width larger than the width of the remaining part of the scroll wall. At the radially inner portion, the groove is also widened. When molding the scroll member, a recess deeper than the depth of the groove to be machined is created. The groove is obtained by machining the scroll member as molded by a milling tool. The widened portion of the groove is formed by moving a milling tool along a closed trajectory, so that the recess is left un-machined.

摘要： A variable displacement compressor is disclosed that draws refrigerant from a suction pressure zone and discharges the refrigerant to a discharge pressure zone, and controls displacement according to a pressure in a control pressure chamber. The compressor has a cam body, pistons, a supply passage, a release passage, and an on-off valve. The inclination angle of the cam body is changeable based on the pressure in the control pressure chamber. A piston reciprocates in each cylinder bore as the cam body rotates. The supply passage supplies the refrigerant in the discharge pressure zone to the control pressure chamber. The release passage releases the refrigerant in the control pressure chamber to the suction pressure zone. The on-off valve selectively opens and closes the release passage in response to changes of the temperature. The on-off valve shuts off the release passage when the temperature is equal to or higher than a predetermined temperature.

摘要： A variable displacement compressor includes a swash plate guiding member that rotates integrally with and inclines relative to a drive shaft, a swash plate supported by the guiding member, and a piston engaged with the swash plate via a shoe. A clutch is located between the guiding member and the swash plate. The clutch is switched between an engaged state, where the clutch permits the guiding member and the swash plate to rotate integrally, and a disengaged state, where the clutch permits the guiding member and the swash plate to rotate relative to each other. Therefore, the compressor is capable of switching between a state where improving the displacement controllability is prioritized and a state where reduction of mechanical loss between the swash plate and the shoes is prioritized.

摘要： A variable displacement compressor has a control valve for controlling the displacement of the compressor. When the pressure in a discharge chamber of the compressor (discharge pressure) is equal to or higher than a first threshold value, a controller executes a limiting control for limiting the discharge pressure. During the limiting control, the controller gradually decreases a duty ratio, which is sent to the control valve, such that the displacement of the compressor is gradually decreased. When the duty ratio is decreased to a reference duty ratio, the controller sets the duty ratio to zero %. As a result, the compressor displacement is minimized and the discharge pressure is lowered. Therefore, the pipes of an external refrigerant circuit does not receive excessive load based on high discharge pressure.
摘要翻译： 可变排量压缩机具有用于控制压缩机的排量的控制阀。 当压缩机的排出室中的压力（排出压力）等于或高于第一阈值时，控制器执行用于限制排出压力的限制控制。 在限制控制期间，控制器逐渐减小发送到控制阀的占空比，使得压缩机的位移逐渐减小。 当占空比降低到参考占空比时，控制器将占空比设置为零％。 结果，压缩机排量被最小化并且排出压力降低。 因此，外部制冷剂回路的管道基于高排出压力不会受到过大的负荷。

摘要： A control valve in a compressor that adjusts the discharge displacement based on controlling of an inclination of a cam plate. The compressor includes a supply passage for connecting a discharge chamber with a crank chamber. The control valve is placed midway on the supply passage. The control valve has a valve body. The valve body moves in a first direction to open the supply passage and moves in the second direction to close the supply passage. A reacting member reacts to suction pressure. A first transmitting member is placed between the reacting member and the valve body. A solenoid is opposed to the reacting member with respect to the valve body. The solenoid urges the valve body in the second direction via a second transmitting member when the solenoid is excited. An urging device urges the valve body in the first direction, The first transmitting member connects the reacting member with the valve body to move the valve body toward or away from the reacting member. The urging device causes the valve body to fully open the supply passage when the solenoid is de-exited.
