Abstract: A dual passage valve with four way controls comprises a synchronized poppet combination reciprocally mounted within the valve housing. There is a bore axially formed in the housing with two fluid passageways located at the proximal and distal ends of the bore. There are also inlet and outlet ports formed in the housing with the inlet port extending radially from the bore, and the outlet port having conduits extending into the two fluid passageways. The synchronized poppet combination selectively encloses and opens the bore to the two passageways allowing fluid to traverse through, stops at, and reverse from the valve synchronously in a one-stroke linear motion within the bore. The synchronized poppet combination distinctively dictates the fluid flow traffic and strictly forbids any disorderly fluid flow states within the valve.

Abstract: A digitally controlled valve system is composed of the main fluid control valve with a displaceable flow control portion (spool) that is controllably displaced by a digital pressure generator that generates digitally incremented pressure changes which operate against a biassing pressure or spring to displace the spool in a direct relationship to the pressure provided by the pressure generator. In one version, a main valve directs flow to either a high or a low pressure-control valve each of which is biassed toward a closed position by a pressure substantially equivalent to the pressure drop of flow of fluid through the main valve which pressure closes the valve stop flow when the pressure drop is too high (i.e. flow through the main valve is throttled). The flows through the valves are selectively adjusted via the digitally-generated pressure from the digital pressure generator. In another version of the invention the two pressure control valves are replaced by a two direction control valve that directs flow to or from the main valve which is connected to an output line. The flow rate is dependent on the spool displacement of the main valve. The position of the spool of the two direction control valve in the later version is adjusted based on the pressure drop across the main valve. Properly sizing of the flow passage orifices (and biassing pressure i.e. springs) in the main valve provides a valve system where the flow varies directly with the amount of pressure applied to displace the spool of the main valve.

Abstract: In a housing, there is formed, in series, a first end cavity, a first cylinder cavity, a pressure cavity, a second cylinder cavity and a second end cavity. The cavities are separated by walls which include orifices. Two identical valve members are located in the housing. The first valve member has a piston and a valve plug in the first end cavity and a valve plug in the pressure cavity. The second valve member has a piston and a valve plug in the second end cavity and a valve plug in the pressure cavity. Pressure in the pressure cavity acts on the confronting ends of the two valve members. A two position control rod, in a first position, connects pressure to the piston in the first end chamber and connects the second end chamber to return. The piston has a larger area than the second end of the valve member, creating a force differential which moves the first valve member endwise inwardly. Pressure acting on the second end of the second valve member moves it endwise outwardly. The same control rod, in its second position, connects the second piston with pressure and the first piston with return. Pressure acting on the second end of the first valve member moves it endwise outwardly. Pressure acting on the second piston moves the second valve member endwise inwardly. Such movement of the valve members moves the valve plugs to open and close orifices in the separator walls, to switch pressure and return between two paths leading from the valve assembly.

Abstract: A multiplexed hydraulic control system which avoids the use of a rotary multiplexer and thereby allows for random selection of the multiplexed outlet ports and variable dwell times for the respective ports. A single hydraulic input is multiplexed among a plurality of hydraulic outputs. A control system provides two types of signals: (1) modulation signals selected from a plurality of multiplexed input signals for producing a modulating hydraulic flow, and (2) selector signals for operating on the multiplexer means to route the modulated signal to the appropriately selected channel.

Abstract: An improved pneumatic control valve apparatus which uses poppet valves as the primary valve components. The poppets are in a pair of poppet valve assemblies, each assembly containing a pair of spaced poppets on a shiftable shaft biased in one direction to cause the poppets to close respective valve seats and to open the valve seats when the shaft moves in the opposite direction. A roller diaphragm is used to couple the shaft to an adjacent support of the assembly. As the shaft moves in the opposite direction against a bias force, the roller diaphragms of each assembly flex in a rolling action to coordinate the movements of the poppets and the shaft. The poppets will simutaneously open their respective valve seats so that the same amount of fluid will flow through the valve seats and thereby assure precision movements of the shiftable parts of the work-producing device with which the poppet valve assemblies are coupled. The poppet valve assemblies of the present invention can be controlled by a control unit, such as a piezoelectric transducer operable as a function of the polarity and magnitude of a voltage applied to the transducer.

Abstract: A pilot operated directional control valve having a diaphragm held between a passage block which has a feeding port, at least one loading port and at least one discharge port, and an opposed control block which has pilot pressure passages. The ports of the passage block open into the end face of the passage block adjacent to the control block through respective fluid passages. The pilot pressure is exerted on the diaphragm by the pilot pressure passages to control the fluid connection between the ports of the passage block. The fluid passages are located in a concentric arrangement.The diaphragm has a center valve portion with an annular valve portion therearound. The two valve portions can be independently controlled by the pilot pressure acting thereon to control the fluid connection between the two adjacent fluid passages.

Abstract: The disclosure is directed to a valve arrangement for controlling a linear or rotary hydraulic motor. The valve is connected to a pump which acts as a pressure medium source by the valve means and to a tank. The tank connection may be either direct or indirect. The arrangement of the present invention includes at least one seat valve located in a main flow connection between the pump and a port of the motor. Each of the seat valves would adjust the flow in the main flow connection to the motor via a pilot flow adjustable by a pilot valve. The pilot flow originates from the main flow through the seat valve.

Abstract: A hydraulic control system comprising a hydraulic actuator having opposed openings adapted to alternately function as inlets and outlets for moving the element of the actuator in opposite directions and a variable displacement pump with loading sensing control for supplying fluid to said actuator. A pair of meter-in valves are provided to which the fluid from the pump is supplied and a pilot controller alternately supplies fluid at pilot pressure to a meter-in valve for controlling the displacement of movement of the meter-in valve and the direction and velocity of the actuator. Alternately pilot pressure from the pilot controller is applied simultaneously to both of the meter-in valves in conjunction with the venting of one of two load drop check valves to provide a regenerative mode.A line extends from the meter-in valve to its respective opening of the actuator and a meter-out valve is associated with each line of the actuator for controlling the flow out of the actuator when that line to the actuator does not have pressure fluid from the pump applied thereto. Each meter-out valve is pilot operated by the pilot pressure from the controller.In a modified form, utilizing a single actuator, the hydraulic control system includes a single meter-in valve associated with one opening of the actuator.
