摘要： A method of monitoring operation of a fuel system includes urging a fuel flow from a fuel source toward a pressure regulating valve via a fuel pump. A pressure of the fuel flow is detected at the pressure regulating valve, and a pump speed required to produce a selected pressure at the pressure regulating valve is detected. The pump speed is compared to a range of acceptable pump speeds, and an operational status of the fuel pump is determined based on a result of the comparison.

摘要： An example vane pump comprises a shaft driving a rotor. The rotor has a plurality of vane grooves, with a vane received in each of the plurality of vane grooves, and an under vane chamber for communicating a pressurized fluid into the grooves to bias the vanes radially outwardly of the rotor. A cam ring is positioned radially outwardly of the rotor. The cam ring is free to rotate with the rotor through friction from the vanes as the rotor rotates. An inlet delivers a fluid to be pumped into an inlet chamber, and an outlet receives the fluid pumped by the vane pump. An outlet for the fluid biasing the vanes communicates to a main outlet through a passage including a valve to increase the pressure of the fluid in the grooves.

摘要： In order to provide a control valve for reducing the pressure of a fluid flowing through a system, while also achieving the pressure reduction in an acoustically damped manner, the flow control valve utilizes pressure reduction chambers for reducing fluid pressure in an incremental manner together with a porous insert associated with the pressure reduction chambers for acoustically damping noise generated during the pressure reduction. The flow control valve includes a valve housing having a valve chamber in direct fluid communication with a fluid inlet and having a plurality of spaced openings through which the fluid inlet communicates with the fluid outlet. By utilizing these components in the valve, the pressure reduction chambers can be disposed generally intermediate the valve chamber and fluid outlet, and the porous insert can be disposed between the pressure reduction chambers and the fluid outlet, whereby the porous insert in the hollow valve housing will further reduce fluid pressure in an acoustically damped manner upstream of the fluid outlet.
