Abstract:
A control system for deactivation of valves in a multiple-cylinder internal combustion engine having a pressurized oil source and hydraulically-operable deactivation valve lifters, comprising:a) a hydraulic manifold having a plurality of oil galleries connected between said oil source and said lifters; b) a plurality of independently-controllable solenoid control valves disposed on said manifold and extending into said galleries, said control valves being operable for activation and deaactivation of lifters associated with one or more of said cylinders by controlling the flow of pressurized oil to said associated lifters; and c) a lead frame connector/retainer mounted on said manifold for retaining said control valves in said disposition on said manifold and for carrying electrical signals to said control valves for activation and deactivation of said lifters.
