Abstract
The disclosure illustrates a gate type valve which is actuated to block off the exhaust system of an internal combustion engine thereby creating a back pressure which retards rotation of the engine. The gate valve has a series of ports which are selectively uncovered by appropriate inputs to the valve actuator to minimize force requirements when the valve is opened and to limit the amount of engine valve float at relatively high R.P.M.
