A first passageway communicates between the control chamber and a first port and a second passageway communicates between the control chamber and a second port. A control valve is associated with at least one of the passageways to permit fluid flow therethrough and to urge the valve member into one of a seated or lifted position.

Abstract: A drain valve has an inlet (36) for liquids and small solids, an accumulation chamber (37) and an outlet (17). The outlet has a seal (13) which is connected to an air-activated piston (12). The piston is in turn connected to a positive air pressure inlet (18) via an air communication path (19) and a closure (22). The closure (22) is opened by a closure activation means (29), causing positive air pressure to flow to the piston (12), which briefly causes the outlet seal (13) to be opened, allowing liquids and small solids from the accumulation chamber to be expelled. Upon de-activation by the closure activation means (29), the closure (22) recloses, blocking the supply of positive air pressure to the piston (12).

Abstract: A diaphragm-type control valve for irrigation systems has an outer clam-shell housing that encloses a vertically reciprocable diaphragm assembly. A primary valve seat inside the housing is engaged and disengaged by a seal on the underside of the diaphragm to open and close the valve by connecting and disconnecting its inlet and outlet passages. Pressurized water from a lower inlet chamber of the valve travels through a small metering orifice in the center of the diaphragm assembly to an upper pressure control chamber above a flexible membrane of the diaphragm assembly. A solenoid actuated pilot valve is operatively coupled to the upper pressure control chamber for venting pressurized water therefrom to permit the diaphragm assembly to move upwardly to open the valve. A filter screen is mounted to the underside of the diaphragm assembly to prevent debris from clogging the metering orifice, clogging the small passages of the pilot valve, or fouling the solenoid.

Abstract: A valve controlled by the same medium it handles and released by a preferably electromagnetically activated control valve. Contaminants in the medium that clog up the control bore in servocontrolled valves that employ a differential piston, a relief bore that can be closed off with a control valve, and a control bore that connect a pressure connection with a control space prevent the valve from closing. A mechanism that is especially simple in design is proposed to constantly keep the control bore clean during operation. The control space accommodates a wire spring that rest against the differential piston and against the valve housing and extends through the control bore. The motion of the piston is accompanied by a relative motion between the control bore and the spring that results in a constant cleaning action. The valve is especially practical in water lines and has the advantage of constant self-cleaning on the part of the control bore.

Abstract: The pressure relief valve is debris resistant, self-cleaning, and self-actuating in a cryopump. It includes an o-ring carried by a valve member within a valve cylinder. In opening, the valve member moves away from an end port to open vent ports in the side of the valve cylinder while withdrawing the o-ring to a debris free and protected region of the valve. As the valve member is moved into the closed position in response to an atmospherical pressure differential, a wiper ring cleans debris from the inner surface of the valve cylinder. A taper is provided on the inner surface of the cylinder to release compression on the vacuum sealing o-ring upon opening and to compress the o-ring as the valve member moves to the closed position. The wiper ring is expansible in order to provide a wiping action along the entire taper and prevent debris from reaching the o-ring. The end of the valve cylinder opposite to the end port serves as a shock absorber as the valve is opened.

Abstract: A pan-type liquid distribution assembly or fractionator which regulates the liquid flow through distribution tubes and, at the same time, provides for clearing away of unwanted fouling material which, in the past, has served to detract from the operation by plugging or partially plugging the liquid pour-points. Adjustment of the flow through, and/or, the unfouling of, the liquid pour-tubes can be performed from a point external of the fractionator, so as not to interfere with the ongoing operation of the fractionation column. A further feature is the ability to adjust liquid flow through each individual tube to alter the distribution pattern of the liquid across the top of a packed fractionation bed.
