Abstract
An improved compression release retarder for internal combustion engines is disclosed. The improvement comprises hydro-mechanical mechanisms incorporated principally into the slave piston and adjustable stop which assures a prompt closing of the engine exhaust valve following a compression release event and provides means to advance the opening of the exhaust valve to begin the compression release event. The mechanism is automatic in that the exhaust valve opening advance mechanism alters the valve train lash to a predetermined level whenever the engine retarder is operated and the exhaust valve closing mechanism acts in response to the decrease in engine cylinder pressure during the compression release event.
