摘要： Multi-stage intensifiers for injectors of pressurized fluid (e.g., fuel) allowing selection of intensified injection fluid pressure and thus fluid injection flow rate by selectively applying actuating fluid supply pressure to one or more of the multi-stage intensifiers. In a disclosed embodiment, two coaxial unequal sized intensifier pistons are used, with a control valve controlling selective pressurization of either the relatively smaller intensifier piston, or pressurization of both the relatively smaller intensifier piston and the relatively larger intensifier piston to control the intensified injection fluid pressure and flow rate of injection. Other embodiments, including ones using multi-stage intensifiers mechanically coupled together, controlled by different types of control valves and having more than two stages are also disclosed.

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.

摘要： A valve module that can be assembled to an internal combustion engine chamber. The valve module may have a first intake valve, a second intake valve, a third intake valve, a first exhaust valve and a second exhaust valve. The valves may be driven to an open position by hydraulically driven first pins. The exhaust valves may further have hydraulically driven second pins. The additional pins may increase the hydraulic forces which allow the exhaust valves to be opened even when there is a large pressure in the combustion chamber. The first pins of the exhaust valves may be controlled by a microprocessor controlled first control valve. The second pins may be controlled by a microprocessor controlled second control valve. The separate control valves and additional hydraulic force of the second pins may allow the microprocessor to open the exhaust valves at any point during a cycle of a combustion engine.

摘要： An intensified fuel injector which has at least one lateral or side drain passage. The fuel injector may include a valve body which has longitudinal axis. The valve body may have a fuel chamber that is hydraulically coupled to a fuel supply port and at least one nozzle opening. An intensifier moves within the fuel chamber. The intensifier is hydraulically coupled to an intensifier chamber and also connected to a biasing spring. The spring is located within a spring chamber that is hydraulically coupled to the drain passage. The drain passage may extend through the valve body in a direction that is substantially perpendicular to the longitudinal axis of the body. The orientation and position drain passage minimizes the diameter or cross-sectional area of the fuel injector by eliminating a longitudinal passage typically found in fuel injectors of the prior art.

摘要： A flow control valve that has a solenoid operated pump that moves a poppet between an open and a closed position. The valve has a housing with an inlet, an outlet and a housing chamber that can allow fluid to flow from the inlet to the outlet. The poppet is located within the housing chamber and is adapted to move from an open position to a closed position, to control the flow of fluid through the valve. Attached to the poppet is a pump that has a first pump chamber separated from a second pump chamber by a wall. The wall has a first one way valve that allows fluid to flow from the second chamber to the first chamber. The second chamber has a diaphragm attached to a solenoid. The solenoid is provided with a series of energizing pulses that move the diaphragm and cause the second chamber to expand and contract. The pumping action of the second chamber causes fluid to flow into the first chamber. The first chamber thereby expands and moves the poppet into the open position. When the pump is turned off, a return spring moves the poppet back into the closed position.

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 control valve that has a pair of solenoids which move a spool between first and second positions. The spool and housing are constructed from a magnetic steel which maintains the spool in either the first or second position. The spool is located within a valve chamber of a housing which has at least two fluid ports. The valve controls the flow of fluid between the ports in accordance with the position of the spool. The valve can be constructed to be either a two-way, three-way or a four-way valve. The spool has an inner chamber which is in fluid communication with both the valve chamber and the drain port of the valve. The inner chamber insures that the ends of the spool are balanced and that a hydraulic pressure does not build up in the valve chamber.

摘要： A camless intake/exhaust valve for an internal combustion engine that is controlled by a solenoid actuated fluid control valve. The control valve has a pair of solenoids that move a spool. Energizing one solenoid moves the spool and valve into an open position. The valve spool is maintained in the open position by the residual magnetism of the valve housing and spool even when power is no longer provided to the solenoid. Energizing the other solenoid moves the spool and valve to a closed position. The solenoids are digitally latched by short digital pulses provided by a microcontroller. The valve is therefore opened by providing a digital pulse of a short duration to one of the solenoids and closed by a digital pulse that is provided to the other solenoid. The valve may be opened by a plurality of pins. One of the pins may engage a stop so that the valve is initially opened with a relatively high force and then moved into the fully opened position with a lower force.
