摘要： A pressure relief valve includes a valve body having a valve seat fluidly positioned between an inlet and an outlet. A valve member is movable among a first position, a second position, and a third position. The valve member is in contact with the valve seat and fluidly blocks the inlet from the outlet at the first position. At the second position of the valve member, the inlet is fluidly connected to the outlet via a small flow area. The inlet is fluidly connected to the outlet via a large flow area when the valve member is at the third position. An electrical actuator is attached to the valve body and is operably coupled to move the valve member when energized. The valve member includes an opening hydraulic surface exposed to fluid pressure in the inlet when at the first position. A spring is operably positioned to bias the valve member toward the second position when the valve member is at the third position.

摘要： A control system for controlling a device, the device having at least two functional elements, each functional element being controlled by a control signal, is disclosed in the present disclosure. The control system may include detecting means operatively connected to the device and configured to monitor the operation of the device, and to generate a signal indicative of an operating condition of the device.

摘要： In an engine equipped with a common rail fuel injection system, the engine can sometimes experience an overspeed condition, and the pump may respond to this overspeed condition with self-actuation even in the absence of any control signal. In order to prevent an over pressurization condition, a liquid supply into a pumping chamber of the pump is limited during a retraction stroke of a pump plunger by energizing an electrical actuator coupled to a spill valve, to move the spill valve toward a closed position. The electrical actuator is de-energized during a pumping stroke of the pump plunger to allow the spill valve to more toward an open position. Liquid from the pumping chamber is discharged through the spill valve during the pumping stroke, but over pressurization is avoided by limiting the amount of liquid that can enter the pumping chamber during the retraction stroke.

摘要： A common rail fuel system includes a common rail supplied by an inlet metered high pressure pump and fluidly connected to a plurality of zero-leak fuel injectors. An electronic controller controls pressure in the common rail predominantly responsive to a rail pressure error when outside of an overshoot avoidance condition corresponding to the error being less than a first threshold and a time rate of change of the error being greater than a second threshold. Pressure in the common rail is controlled predominantly responsive to the time rate of change of the error during the overshoot avoidance condition.

The spacer has a generally ring-shaped body, which has first and second facing surfaces separated by a thickness. The spacer is positioned between a movable member of the pump and a stationary member of the pump such that the first facing surface of the spacer is contactable with the movable member and the second facing surface is contactable with the stationary member. The spacer has at least a fluid receiving groove formed in at least one of the first and second facing surfaces.

摘要： A method for controlling transfer from use of a first injection waveform type to use of a second injection waveform type in a hydraulically-actuated electronically-controlled fuel injection system of an engine includes sensing an engine speed and an engine load when the first injection waveform type is selected and storing the sensed engine speed and the sensed engine load. An actual engine speed is thereafter compared with the stored engine speed and an actual engine load is thereafter compared with the stored engine load. Transfer from use of the first injection waveform type to use of the second injection waveform type is prevented unless at least (i) a difference between the actual engine load and the stored engine load exceeds a predetermined load amount, or (ii) a difference between the actual engine speed and the stored engine speed exceeds a predetermined speed amount.
