A hydraulic distribution valve having two substantially identical, molded plastic shells which are joined at their peripheries to form the distribution valve housing. A shaft is journaled within the housing and extends through one of the shells. A rotor is coupled to the shaft and is rotatably disposed within a rotor chamber defined by the housing. Each shell additionally defines a plurality of axially disposed cavities, where at least two of the cavities of the second shell communicate with the rotor chamber. The second shell also defines an inlet which communicates through a gallery which passes through a portion of the shaft and rotor for communication between the inlet and a control port which is defined by the rotor. The shaft and rotor can be rotated to align the exhaust port with a selected cavity to permit communication between the inlet and the selected cavity.

Hydraulic distribution valve

A valve made from substantially all plastic parts that has integrally molded valve seats. A unique valve disk comprises two identical, mirror-image, molded plastic parts. The parts are of thin-walled construction but are joined together to give the valve body a substantially thick cross section with elongated shear surfaces in the radial direction. End flanges on the seal disk parts mechanically trap the soft sealing material and provide the maximum depth along the force line of contact between the sealing seat and the seal disk. The valve body has a cylinder and a cylinder cap of identically molded, mirror-image parts which house a diaphragm that overlies a plastic domed piston. The domed piston is provided with radially spaced circular ribs for supporting the diaphragm against excess deflection.

Valve and actuator

Apparatus for separating water from oil employing a cylindrical, axially compressible, flow-through, oleophilic, hydrophobic reticular foam filter body covered peripherally with and bonded to a flow impervious flexible skin of resin impregnated fabric anchored at one end within a pressure vessel by a flow-through cap assembly sealing the adjacent end of the sleeve to the chamber wall. With the remainder of the sleeved filter body slidably retained and backed within such filter chamber, pressure applied intermittently to its opposite end compresses the filter body to squeeze oil accumulations therefrom. Cap means with one-way valve elements on such opposite end of the filter body permits flow of water through the filter body in one direction while obstructing reverse flow under fluid back pressure introduced into the downstream end of the pressure vessel so as to compress the filter body axially. Back-pressure fluid also entering the narrow gap surrounding the sleeve and the pressure vessel wall helps prevent binding of the accordioning sleeve therein during compression cycles.

Regenerable flow-through oil/water separation apparatus

A flow-through coalescing separator applicable to clean immiscible liquids and to dirt-carrying immiscible liquids, such as dirty oil and water mixtures. A normally retracted piston periodically backwashes and thereupon compresses the filter body in a pressure vessel so as to purge the filter body of accumulations of dirt and hydrocarbons. When the piston is thereafter being retracted by restoration of input liquid flow pressure, positive coupling of the piston to the filter body stretches it back to its original length and thereby to the full functioning open-pore condition despite wall friction and limited rebound capability of the filter body material. The system lends itself to manually controlled operation and to automatically controlled operation, either in the continuous flow-through mode or in the more frequently interrupted retention flow-through mode. In either mode the system provides predictably-metered backwash liquid volume determined by pressure vessel capacity from its input chamber to the working face of the piston.
