Abstract
A hydraulic manifold assembly for variable actuation of engine valves. First and second plates have portions of flow passages integrally molded therein. The plates are formed preferably by injection molding of a suitable polymer, for example, glass-filled PPA, and are joined together as by cementing or preferably by fusion welding along mating surfaces to form the full pattern of flow passages. The assembly further comprises a retainer for retaining a plurality of individual solenoid-actuated valves in sockets formed in the plates. The retainer is similarly formed preferably by injection molding of a suitable polymer and is formed to function simultaneously as a positive crankcase ventilation (PCV) baffle.
Claims9
A retainer for holding a plurality of solenoid valves in a hydraulic manifold assembly for activation and deactivation of engine valves in an internal combustion engine, wherein said retainer is a positive crankcase ventilation baffle connectable to an intake manifold of said engine.
A retainer for holding a plurality of solenoid valves in a hydraulic manifold assembly for activation and deactivation of engine valves in an internal combustion engine, comprising:
- a) a hollow longitudinal member;
- b) a plurality of buckets attached to said member, each of said buckets being supportive of a one of said plurality of solenoid valves in operating position in said manifold;
- c) an entry aperture into said hollow longitudinal member;
- and
- d) an exit fitting for connection to an intake manifold of said engine.
