On/off solenoid ball valves of the invention comprise at least one inlet port; at least one pressure control outlet port; at least one exhaust port; at least one check valve positioned between the pressure control outlet port and the exhaust port; and at least one bypass orifice positioned to allow inlet fluid flow to the pressure control outlet port irrespective of whether the valve is in the 'on' or 'off' position. Because of their ability to provide unique and controlled flows, valves of the invention are able to be used in applications previously off limits to on/off solenoid ball valves.

A lead frame has slots therein for bayonet type connection to electrical terminals provided on a solenoid valve or group of valves. Projections on the lead frame are disposed between the slots and upon bayonet connection to the terminals closely interfit a web disposed between the terminals on the solenoid. Preferably, support stanchions are provided for the terminals and may be integrally molded with the web.

A hydraulic fluid cam providing variable valve actuation in an engine is disclosed. In one embodiment, the hydraulic fluid cam is adapted to vary valve timing while holding valve displacement constant. In another embodiment, the hydraulic fluid cam is adapted to vary valve displacement, while holding valve timing constant. Some embodiments are adapted to vary both valve timing and displacement simultaneously to optimize engine performance.

A three-prong integrally formed resilient seal for sealing the juncture of three gasketed members. The seal has a common region having an embedded strain distributor of stiffer material than the remainder of the seal which is integrally formed, preferably by insert molding as a one-piece member.

A solenoid operated valve has first flux collector, bobbin with coil and an armature assembled onto a valve body with a tubular housing received over the body and first portions of the housing, in the form of tabs, deformed over the bobbin flange to retain the assembly. A second flux collector with adjustable pole price is then assembled adjacent the bobbin and retained in place by deformation of second portions of the housing. The pole piece is accessible exteriorly for adjustment through the end of the housing.

Solenoid operated valve and method of making same

An electro-hydraulic manifold assembly for deactivation of the valves of one bank of cylinders in a V-10 engine. One solenoid valve controls flow of oil to the hydraulic valve lifter/lash adjuster of a single or first cylinder, a second valve controls flow of oil to the lifters/lash adjusters of cylinders two and five and a third valve controls oil flow to the lifters/lash adjusters for cylinders two and three by taking advantage of the common base circle position of the cams for the paired cylinders.

A Lifter Oil Manifold Assembly or LOMA has a metal deckplate with a non-metallic valve mount/stiffener having elastomeric seals on the surface contacting the deckplate. The electrically operated valves for controlling flow to individual valve lifters are mounted on bosses formed on the valve mount/stiffener. A bracket retains the valves on the valve mount/stiffener and the valve mount/stiffener on the deckplate when assembled on the engine by through bolts.
