    Abstract: A two, three or four-way valve includes two stages each with working valve components linked by a feedback spring so that a first stage servo unit is auto-nulling and the stroke of the valve member in a second stage valve unit is proportional to the input current to the first stage. An inherently balanced clevis member in the first stage controls flow of pressurized control media, which in combination with direct pressure flow, controls the position of a spool member in the second stage. The spool in turn controls pressure flow to a either one or two metering or input/output flow ports. Transient movement of the clevis due to change in input current to a magnetic servo drive assembly is opposed by bending of the feedback spring arising from the associated movement of the spool, which returns the clevis to its centered null position and stops the spool.

    Abstract: A closed loop pressure controller system that sets, measures and controls the process pressure within a semiconductor process is shown. The system is commonly composed of a pressure sensor to collect the pressure information, a controller box that hosts the control electronics, and a valve to physically affect the conductivity of the inlet or outlet gas line and accordingly the process pressure. The present invention differs from the prior art by using closed-loop motor control of the valve, rather than the method of the prior art, where the valve position is controlled by a stepper motor actuator driven in an open loop fashion. It is demonstrated that the utility of such prior art open-loop configurations is limited by the fact that the achievable precision of the valve position is hindered by static friction in the valve system, and the non-linear character of the torque versus shaft-angle of the motor (among other error components). The method of the present invention more accurately positions the valve, and accordingly enhances the overall precision and allowable loop-gain of the pressure control system by providing the valve drive with feedback as to the actual angular position of the valve in extremely high resolution. The closed-loop motor control approach of the present invention has also been adapted to other semiconductor and vacuum processing applications, including linear and rotary feedthrough devices and impedance matching networks.

    Abstract: Hydraulic engine valve actuation systems and methods for internal combustion engines. The systems utilize a proportional valve to regulate the flow of a working fluid to and from a hydraulic actuator controlling the engine valve position. The position of the proportional valve is controlled by one or more high speed valves to control various engine valve parameters, including engine valve takeoff and landing velocities. Returning all valves to a known starting position between engine valve events avoids accumulation of errors in proportional valve positioning. Embodiments using spool valves for the high speed valves and the proportional valve, and spring return and hydraulic return for the engine valve, are disclosed. A specially shaped spool in the proportional valve provides enhanced control over the engine valve operation. Various further alternate embodiments are disclosed.

    Abstract: This invention generally concerns electronically controlled hydraulic valves for use in electro-hydraulically controlled transmissions. The proportional pressure control valve 20 includes a hollow cage 42 pierced by cage tank ports 52, cage clutch ports 54, and cage pump ports 56. The cage pump ports 56 receive fluid from a pump. The cage clutch ports 54 supply fluid to a hydraulic actuator. The cage tank ports 52 return fluid from the valve 20 to a tank from where fluid circulates back to the pump. Main spool 112 controls fluid flow between cage clutch ports 54 and cage pump ports 56 or cage tank ports 52. An electromagnetically operated pilot valve regulates fluid pressure applied to a control pressure surface 138. A feedback pressure passage 126, having a feedback restriction orifice 128, restrains the rate fluid flows between the cage clutch ports 54 and the feedback pressure surface 114.

    Abstract: A spool valve may be used in a subsea system with a single upstream pilot valve to control the spool valve. The spool valve opens and closes a main valve in response to fluid signals from the pilot valve. The main valve is connected to a source of pressurized supply fluid, which is selectively directed to a downstream apparatus. The spool valve and the main valve can be produced in an integrated design with a single body. In an alternative embodiment, the spool valve and main valve are separate with separate bodies. The spool valve may also be used in non-subsea systems.
