摘要： A three position digitally latched actuator actuated fluid control valve. The control valve includes a housing which has a cylinder port, a supply port and a return port. The control valve also contains an internal valve that moves between a first position, a second position and a neutral position. In the first position the internal valve provides fluid communication between the cylinder port and the supply port. In the second position the valve provides fluid communication between the cylinder port and the return port. In the neutral position the valve prevents fluid communication between the ports. The control valve has a first actuator and a second actuator that are actuated by digital pulses to move the internal valve between the first, second and neutral positions. The control valve may have a pair of springs that bias the internal valve to the neutral position, wherein the actuator can be actuated to latch the valve into the first position and the second actuator can be actuated to latch the valve into the second position.

摘要： The present invention is a fuel injection system having one or more fuel injectors and an electronic control system therefore. The preferred fuel injector has a double magnetic latching solenoid three-way or four-way spool valve that controls the flow of a working fluid that is used to control the discharge of fuel into the combustion chamber or intake manifold of an engine through the nozzle of the injector. The control system provides actuating current pulses to each of the solenoids to actuate and latch the solenoids to effect initiation and termination of the injection. Disclosed are control systems that provide a snap action in one or both actuating directions of the valve by electromagnetically retaining the valve in the latched condition until the force in the actuated solenoid builds to a high level, and then releasing the valve for higher acceleration to the actuated position. Also disclosed is an exemplary control system that senses the arrival of valve at the actuated position so that the actuating current pulse can be terminated as soon as possible so as to allow a strong current pulse drive, but of low total energy, for fast actuation of a relatively small valve. Other embodiments, features and uses of the invention are disclosed.

摘要： A fluid flow control valve which has a pair of solenoids that move a hollow ball valve between a first position and a second position. When the ball valve is in the first position, fluid is allowed to flow from an inlet port to a cylinder port. When the ball valve is in the second position, fluid is allowed to flow from the cylinder port to a drain port. The ball valve sits against one of two valve seats which are constructed from steel and a have radial shape that conforms to the shape of the ball. The hystersis of the steel maintains the ball valve in one of the two positions, so that power does not have to be continuously provided to the solenoids. The ball valve has a hollow inner chamber which significantly reduces the weight of the ball and increases the response rate of the control valve.

摘要： A fuel injector that contains no springs and is controlled by a valve assembly that has more than two modes of operation. The fuel injector includes a housing which has a supply port, a drain port and a cylinder passage that is in fluid communication with an intensifier. The intensifier moves between a first position and a second position within a fuel chamber. The fuel chamber is coupled to a fuel port. Movement of the intensifier into the second position pressurizes the fuel within the fuel chamber. The pressurized fuel opens a needle valve so that fuel is ejected through an aperture of the housing. The cylinder passage is coupled to a first fluid control valve and a second fluid control valve. Each control valve can be actuated between a closed position and an open position. When the first control valve is moved to the open position the supply port is in fluid communication with the cylinder passage so that a fluid flows through the passage to push the intensifier to the second position and eject fuel from the ejector. When the second control valve is actuated to the open position the cylinder passage is coupled to the drain port. The intensifier is coupled to a supply line that provides fluid to move the intensifier back to the first position. The needle valve is also coupled to the return line to move the needle back to a closed position.

摘要： A statically and dynamically pressure balanced fluid control valve. The valve contains a spool that is moved within an inner chamber of a valve housing by a pair of solenoids. The ports are symmetrically located on each side of a center port, wherein the resultant fluid forces on the spool are in opposite directions. The opposing forces create a net fluid force of approximately zero, so that the spool is dynamically pressure balanced when the valve is switched to a new position. The spool also has an inner channel and a pair of end openings that are in fluid communication with the inner chamber of the valve. When the spool is pulled to a new position, the end openings and inner channel allow fluid within the inner chamber to flow out of the space between the end of the spool and the housing. The flow of fluid through the end openings and inner channel prevent the formation of hydrostatic fluid pressure that will counteract the movement of the spool. The end openings and inner channel thus statically pressure balance the spool within the valve.
摘要翻译：静态和动态的压力平衡流体控制阀。该阀包括一个阀芯，该阀芯通过一对螺线管在阀壳体的内腔内移动。端口对称地位于中心端口的每一侧，其中所述线轴上的所得流体力处于相反的方向。相反的力产生大约为零的净流体力，使得当阀被切换到新位置时，阀芯是动态的压力平衡的。阀芯还具有内部通道和与阀的内部腔室流体连通的一对端部开口。当阀芯被拉动到新位置时，端部开口和内部通道允许内部腔室内的流体从阀芯的端部和壳体之间的空间流出。通过端部开口和内部通道的流体流动可防止静水流体压力的形成，从而抵消阀芯的运动。因此，端部开口和内部通道使阀门内的阀芯静压。

摘要： Fuel injectors and methods of fuel injection allowing direct control of the flow of fuel at an intensified pressure to the needle. A valve, typically a spool valve, is placed in the fuel passage between the intensifier actuation piston and the needle, and controlled by a control valve which may be independent of the control valve controlling the coupling of actuation fluid and a vent to the intensifier actuation piston. This allows achievement of intensification before initiating injection, and control of multiple injections in a single injection event while maintaining fuel intensification throughout the duration of the injection event. Various embodiments are disclosed, including embodiments having multiple intensifiers, having control of pressure over the needle, having two stage control valve systems for control of intensifier actuation fluid, and combining control of one of the intensifiers and the valve controlling flow of intensified fuel to the needle for injection.

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 control module which controls camless hydraulically driven intake and exhaust valves and an hydraulically driven fuel injector of an internal combustion engine. The module contains a valve assembly to control the intake valve, a valve assembly to control the exhaust valve and a valve assembly to control the fuel injector. 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 and the intake and exhaust valves. The hydraulic fluid opens and closes the intake and exhaust valves. The hydraulic fluid also actuates the fuel injector to eject a fuel into a combustion chamber of the engine. The electronic assembly of each module can be connected to a main microprocessor which provides commands to each assembly. Each electronic assembly processes the command, feedback signals from the hydraulically actuated devices and historical data to insure a desired operation of the fuel injector and intake and exhaust valves.
