    摘要： An internal combustion engine that contains a controller which controls different components such as a fuel injector, an exhaust valve and a by-pass valve of a pump with digital control signals. The engine may have an hydraulically driven fuel injector which ejects a volume of fuel into an internal combustion chamber. The flow of air into the internal combustion chamber and the flow of exhaust gas out of the chamber may be controlled by camless hydraulically driven intake and exhaust valves. The hydraulic actuation of the fuel injector and valves are controlled by solenoid actuated latching fluid control valves. The operation of the injector and the valves is controlled by a controller which provides digital signals to actuate and latch the solenoid control valves. The digital signals consume minimal power and actuate the valves at relatively high speeds. The engine further contains a pump that pumps the hydraulic fluid to the control valves. The pump system contains an hydraulically driven solenoid actuated latching by-pass valve which can be opened to couple the outlet of the pump with a return line. Latching the by-pass valve into an open position allows the output of the pump to be dumped to the return line without requiring additional work from the pump to maintain the by-pass valve in the open position. The by-pass valve can be opened by a digital control signal from the controller. The controller can open and close the by-pass valve to control the rail pressure provided to the control valves.

    摘要： A positive displacement pump assembly (10) which has a hydraulically controlled intake check valve (60) that is controlled by a three-way solenoid control valve (80). The intake valve (60) contains a one-way check valve (64) that opens when the pump piston (18) is on an intake stroke and normally closes when the pump piston is on a power stroke. The check valve further contains a hydraulically controlled piston (76) that can open the check valve during the power stroke so that the output fluid of the pump flows to drain. The piston is controlled by the solenoid control valve. The control valve has a pair of digitally latched solenoids (88, 90). The output pressure of the pump can be regulated by energizing one of the solenoids and applying hydraulic pressure to the piston to open the check valve during the power stroke of the pump. The pump is preferably a dual piston (18, 24) wobble plate (30) pump that incorporates a pair of hydraulically controlled intake check valves that are both controlled by a single solenoid control valve.

    摘要： Disclosed is a control module (10) which controls camless hydraulically driven intake and exhaust valves (20, 22) and a hydraulically driven fuel injector (18) of an internal combustion engine. The module (10) contains a valve assembly to control the intake valve (20), a valve assembly to control the exhaust valve (22) and a valve assembly to control the fuel injector (18). The valve assemblies preferably each contain a pair of solenoid actuated two-way spool valves. The solenoids are actuated by digital pulses provided by an electronic assembly within the module. The solenoid actuated spool valves control the flow of a hydraulic fluid to and from the fuel injector (18) and the intake and exhaust valves (20, 22). The hydraulic fluid opens and closes the intake and exhaust valves (20, 22) as well as the fuel injector (18).

    摘要： A pump module that controls and varies the pressure of a fluid within a hydraulic system. The module includes a housing which has an inlet port (24), an outlet port (26) and a return port (28). The inlet port (24) is typically coupled to a pump. The return port (28) is typically connected to a fluid reservoir. The outlet port (26) is typically connected to a working device such as the fuel injector of an internal combustion engine. The module contains a spring loaded variable volume accumulator which maintains the fluid pressure at the outlet of the module. The module also has a three-way valve that provides fluid communication between the inlet port (24) and the outlet port (28) when in a first position, and fluid communication between the inlet port (24) and the return port (28) when in a second position. The module further includes a pressure transducer (52) that senses the fluid pressure at the outlet port (26) and provides a corresponding pressure feedback signal to an electronic controller.

    摘要： Integrated latching actuators are disclosed which may be used as direct replacements for nonlatching actuators in various applications. The integrated latching actuators comprise a magnetically latching actuator with control electronics packaged therewith so that actuation and release may be controlled through a single control line. The integration of the actuator and control electronics eliminates many potential failure modes of conventional latching actuators and results in greatly reduced power consumption, particularly in low duty cycle applications. Various embodiments are disclosed, including embodiments that may operate directly on microprocessor outputs without special drive circuitry.
