Abstract: A solenoid operated metering pump for displacement of exact amounts of fluid pumped by reciprocation of pumping piston incorporating integral check valve has an elongated valve housing with solenoid operator serving as pump actuating means attached to one housing end while the other housing end is adaptable to serve as the fluid pumping means including an appropriate housing bore passing therethrough and adaptable to receive a differential diameter piston assembly slidably movable therein to reciprocate when solenoid operator becomes electrically cycled inducing fluid flow through appropriate pump chamber created therein between piston and housing bore portion provided with fluid supply port having a detachable check valve with a simple floater for a directional flow control therethrough, means of piston actuation from a first position checking flow and discharge of the fluid delivered to the pump chamber to a second position discharging exact fluid quantity per each stroke of pump reciprocation, and means of

Abstract: Universal momentary contact diverter valve is operated directly by axially disposed solenoid operators at each end of an elongated valve housing having a bore passing therethrough to receive a valving spool therein in an operable relationship with said solenoid operators so as to enable spool shifting directly to result in diversion of fluid flow passing therethrough and fluid exhaust therefrom via passages incorporated therein, energization of operator coils electrically accomplished momentarily by an application of voltage-overcharge-pulse to yield higher than conventional magnetic force.

Abstract: A simple momentary contact diverter valve is operated directly by axially disposed solenoid operators at each end of an elongated valve housing having a bore passing therethrough to receive a valving spool therein in an operable relationship with said solenoid operators so as to enable spool shifting directly to result in diversion of fluid flow passing therethrough between fluid supply and exhaust ports incorporated therein, energization of operator coils electrically accomplished momentarily by an application of voltage-overcharge-pulse to yield higher than conventional magnetic force resulting in more than conventionally accepted pull force spool experiences, thereby increasing capability of handling fluid pressures substantially above those attainable by direct solenoid operated valves of this type.

Abstract: A drastically simplified directional solenoid valve with top fluid inlet and bottom fluid exhaust ports employs a conventional electrical bobbin coil with a solenoid iron conveniently secured thereto in line with a simplified axially movable solenoid plunger in an operable relationship with a simple seal at the exhaust port, preferably of O-ring configuration, between a first plunger engaged position inside the seal to maintain valve normally closed when the solenoid coil is not energized electrically and a second position with plunger retracted from the seat of the seal when the coil is electrically energized turning said iron into a magnet with pull force capable of lifting the plunger from the seat to render valve open to exhaust while the plunger is being held against the iron until the coil becomes de-energized at which time the plunger is automatically shifted back to the first valve closed position against the seat by either the drag forces fluid flow provides or by additional biasing force of a compre

Abstract: A throttle valve for high pressure letdown includes an elongated valve housing with pressure reducing valve section which contains a plurality of conical baffles spaced therein along the length thereof stretching between a high pressure fluid supply port entering said valve housing through housing wall perpendicularly and an axially disposed fluid exhaust port for low pressure discharge of the fluid subjected to torture pathway accompanied by multitude flow reversals with only limited fluid expansion and contraction processes induced thereto forcing fluid expansion when it passes large diameter edge of one baffle first before it is forced to contract immediately thereafter when passing small diameter orifice of another baffle spaced a short distance away until all baffles along the way are crossed extracting huge energy amount from high pressure fluid to result in a low pressure fluid exhaust from the valve, including means for flow and pressure drop modulation by varying position of baffles relative to net f

Abstract: A linear pull actuator converts working fluid such as halogenated hydrocarbons into vapor by electrical heating element housed inside a shell, generating a vapor pressure against a rolling membrane secured inside actuator so as to respond to the vapor pressure linearly delivering an end force to an integral first piston and tube assembly which is adaptable to axially move inside the housing proper against spring biasing means along with an externally mounted second piston of a piston and rod assembly secured thereto by a spring so as to have rod end passing centrally through the tube protrude a distance out of the shell end for a position change from a first rod end protruded when electrical heater is not energized electrically to a second rod end retracted position with work when pulled away by the pistons due to the vapor pressure of the working fluid when the electrical heater is energized electrically, de-energization of the electrical heating element electrically returns the rod end to the first protrude

Abstract: A three ported momentary contact diverter that doubles as a mixer valve, having a housing with a central bore passing therethrough including an axially movable elongated stem slidably received therein,and closed at each end by electrical solenoid operators, allows a pressurized fluid flow from a first fluid supply port to a second fluid receiver port when neither of the solenoids is electrically energized, and reverses the fluid flow from the first fluid supply port to a third fluid receiver port when simultaneously both solenoid operators become electrically energized momentarily to permit pressurized pilot fluid from the supply port to entersolenoid cavity via internally piloted fluid passages inside said elongated stem initiating each with a separate pilot opening in an overlapping relationship at the opposite sides of a central stem piston, comprising valving means, so as to permit pressurization of a first stem end by said pilot fluid while a second stem end is de-pressurized, with resultant stem movemen

Abstract: An internally piloted shut-off valve for use with cryogenic fluids incorporates a short valve housing with normally closed valve closure means incorporated therein and fluid passages with ports for fluid flow therethrough including an elongated extended stem protruding therefrom on top of which a solenoid operator is received in the stem end opening so as to define a cavity therein housing a large piston interconnected with the valve closure means by an internally piloted concentric tubing disposed coaxially with the stem and, in combination with large piston, comprising valve actuating means which permit the use of conventional solenoid operator and a trickle of cryogenic fluid converted to vapor inside pilot passage of the tubing and supplied to the cavity at atmospheric temperature when solenoid is enerized, creating pressure differential therein capable of maintaining valve open until the solenoid operator is de-energized, allowing valve closing automatically.
