Abstract
A valve control apparatus particularly suited for a diesel engine brake. There is an hydraulic actuator having a piston which contacts the valve stem of an exhaust valve. The actuator is independent of the exhaust valve opening mechanism. There is a device, such as an electromagnetically activated valve, which can releasably shut off a flow of fluid from the hydraulic actuator after the exhaust valve is opened by the exhaust valve opening mechanism. The exhaust valve is prevented from closing until a flow of fluid from the hydraulic cylinder is permitted just before top dead center of the compression stroke.
