-27- RETARDING SYSTEM OF A GAS COMPRESSION RELIEF TYPE ABSTRACT OF THE DISCLOSURE A hydraulic reset mechanism is provided for an engine retarder of the compression relief type. The mechanism includes a pin valve and senses the force required to hold open an exhaust valve. When this force has decreased substantially from the force required to open the exhaust valve initially, the pin valve is opened in the hydraulic system to release the hydraulic pressure and permit the exhaust valve to close. The mechanism thereby assures that the engine exhaust valves are closed, or substantially closed, prior to the normal opening of the exhaust valves at the end of the power stroke of the engine without affecting the retarding horsepower produced by the engine brake.
