    摘要: A valve spool (70) for an oil pump assembly (10) that includes a pilot pressure relief valve (80) to provide pilot pressure relief that increases the stability of the pump assembly (10) and eliminates the delay between the change in the discharge pressure and the associated response to the pilot pressure. The valve spool (70) operates in response to the pilot pressure to increase or decrease the pump discharge pressure during vehicle operation. A chamber (72) within the valve spool (70) is in fluid communication with the discharge flow and pressure at one end and the pilot pressure at the other end. When the pilot pressure exceeds the discharge pressure, the relief valve (80) opens, allowing the discharge pressure and the pilot pressure to equalize.

    摘要: The present invention is a variable displacement pump system for delivering precisely controlled oil flow and pressure, including a variable displacement pump having an inlet passage, an outlet passage, a first chamber and a second chamber for controlling the displacement of the variable displacement pump. The present invention also includes a fluid control device for receiving fluid from the outlet passage, and selectively delivering fluid to the second chamber. Fluid is delivered from the inlet passage to the outlet passage from the variable displacement pump, and fluid is also delivered from the outlet passage to the first chamber and the fluid control device. When fluid pressure is greater in the first chamber relative to the second chamber, the displacement of the variable displacement pump will decrease, and when fluid pressure is greater in the second chamber relative to the first chamber, the displacement of the variable displacement pump will increase.

Of course, the vane pump may also be utilized in a wide range of power transmission and other fluid distribution applications. The vane pump of the invention may also use both hydrostatic and mechanical actuators to control the position of its containment ring or eccentric ring and hence, regulate the output of the pump. According to yet another aspect of the present invention, to prevent inlet flow restriction or cavitation, a valve may be provided to permit some of the pump outlet or discharge flow to bleed into the pump inlet to provide needed velocity energy to the fluid flow into the pump inlet. A system for lubrication of an engine using a fixed displacement pump for providing an engine speed input for controlling a second main variable displacement type oil pump and maintaining a target oil pressure in the oil pressure circuit. A solenoid valve is used for venting output of the fixed displacement pump to create a second target oil pressure characteristic or curve when desired.

Of course, the vane pump may also be utilized in a wide range of power transmission and other fluid distribution applications. The variable displacement vane pump of the invention may utilize both hydrostatic and mechanical assistance in radially positioning its vanes to ensure efficient and quiet operation of the pump and to facilitate priming of the pump. The vane pump of the invention may also use both hydrostatic and mechanical actuators to control the position of its containment ring or eccentric ring and hence, regulate the output of the pump. According to yet another aspect of the present invention, to prevent inlet flow restriction or cavitation, a valve may be provided to permit some of the pump outlet or discharge flow to bleed into the pump inlet to provide needed velocity and energy to the fluid flow into the pump inlet.
