A manifold has a supply inlet communicating with a plurality of spaced supply ports; and, has associated with each supply port a separate control pressure passage. A gasket has a plurality of spaced bosses, each with a valving cavity with an electrically operated valve received and ported in the cavity. Each valving cavity has a supply port communicating with one of the supply ports on the manifold and a control pressure outlet port communicating with one of the control pressure passages on the manifold. A plurality of electrically conductive strips are embedded in the gasket and each is connected to a terminal pin in a receptacle shell formed on the gasket. The remote end of each of the conductor strips is exposed adjacent a valve and makes contact with a terminal on the valve when the valve is received in the respective valving cavity. A common retaining bracket is attached to the manifold and retains the valves and gasket as an assembly on the manifold.

A load bearing valve body has an annular collector groove supplied by radial ports connected to an inlet in the end of the valve body. An annular sleeve type armature has a plurality of arcuate slots located thereon to axially valve the collector groove upon solenoid energization.

A one-piece filter cartridge is formed by inserting an open ended cylindrical screen and an end screen for the cylindrical screen in a mold and overmolding with engineered resinous material to form spaced annular and axial support ribs for the screen material. The cartridge is suitable for use in an hydraulic circuit for filtering bi-directional and radial flow without backwashing trapped particles from flow in one axial direction. One of the ribs has an annular groove for a seal ring for sealing about the cartridge upon insertion in a flow passage.

A solenoid valve and manifold assembly for installation on an engine and connecting with hydraulic circuits in the engine for de-actuating the combustion chamber valves of selected cylinders of the engine. A manifold deck is formed with the valving channels and ports therein for connecting to the hydraulic circuits. A gasket is formed with solenoid valve mounting bosses and valving passages as a unitary member and is retained on the manifold deck by a retaining plate preferably stamped from sheet stock with clearance holes received over the valve mounting bosses and secured to the manifold deck over the gasket for sealing the gasket thereon. The valves are inserted in the bosses and retained by a preferably stamped bracket and the bracket, retaining plate and gasket secured to the manifold deck by common fasteners. A common electrical lead frame is received over the valve terminals for making electrical connection to the valves. The assembly of valves and the manifold deck may then be attached to the engine as a unit.

A technique of assembling a solenoid operated valve to a hydraulic manifold in which the manifold has provided thereon undercut stanchions disposed on opposite sides of a cavity communicating with fluid valving passages. A U-shaped bracket with a central aperture is received over the solenoid and a first pair of tabs which engage lugs disposed respectively on opposite sides of the valve body function to prevent relative rotation between the bracket and valve. The bracket has a pair of oppositely extending resiliently deflectable spring arms each having a pair of second tabs thereon; and, the spring arms are deflected on the stanchions upon user insertion of the valve body into the cavity. The spring arms resiliently engage the undercuts to prevent removal of the valve, and the second tabs engage the sides of the stanchions to prevent relative rotation of the bracket and valve.
