摘要： A variable displacement vane pump has a pressure controlled valve moveable between first and at least second valve positions based on an output pressure of the pressurized lubricant delivered through the outlet. The pressure controlled valve provides an integrated fail safe function to the pump when an electrical valve fails. The pressure controlled valve is inactive in the first position for an output pressure below a threshold level, allowing an electrical valve (current, solenoid, pulse width modulation (PWM) valve) to selectively control pressure in the control chamber under normal operation of the pump. In fail safe regulation mode, the electrical valve function is disabled and the pressure controlled valve is active in its second position, controlling pressure in the control chamber. Channels and vents in the pump can be opened and closed based on selective movement of the valve when the outlet pressure is at or above a threshold level.
摘要翻译： 可变排量叶片泵具有压力控制阀，其基于通过出口输送的加压润滑剂的输出压力在第一阀位位置和至少第二阀位置之间移动。 当电动阀故障时，压力控制阀为泵提供了一个集成的故障安全功能。 压力控制阀在第一位置处无效，输出压力低于阈值水平，允许电动阀（电流，螺线管，脉宽调制（PWM）阀）在泵的正常运行下选择性地控制控制室中的压力 。 在故障安全调节模式下，电气阀功能被禁用，压力控制阀在其第二位置处于活动状态，从而控制控制室中的压力。 当出口压力等于或高于阈值水平时，可以基于阀的选择性运动来打开和关闭泵中的通道和通风口。

High lubricant pressure in a control chamber (54) causes the control ring (28) to be moved to a low pumping volume direction against the pretensioning element (74). A pump outlet cavity (14) is connected fluidically to the control chamber (54). The control ring (28) is provided with a pressure-relief-valve (52, 52') integrated into the control ring (28) and connecting or disconnecting the control chamber (54) with the pump compartment (19

摘要： A variable capacity vane pump (20) is provided having a pump control ring (44) that is moveable to alter the capacity of the pump (20). A control chamber (60) is formed between the pump casing (22) and the control ring (44). The control chamber (60) is operable to receive pressurized fluid to create a force to move the control ring (44) to reduce the volumetric capacity of the pump (20). A primary return spring (56) acts between the control ring (44) and the casing (22) to bias the control ring (44) towards a position of maximum volumetric capacity. A shaft is coupled at one end to the control ring and a second end of the shaft is positioned a predetermined distance from the casing (22). A secondary return spring (62) is mounted about the shaft and is configured to engage the control ring (44) after the control ring (44) has moved a predetermined amount. The secondary return spring ( 62) biases the control ring (44) towards a position of maximum volumetric capacity. The secondary return spring ( 62) acts against the force of the control chamber ( 60) to establish a second equilibrium pressure.
