Abstract
A pressure relief system for an internal combustion engine compression relief engine brake is disclosed. The pressure relief system comprises a bi-stable ball relief valve associated with the high pressure hydraulic system together with damping means adapted to damp out rapidly the oscillations of the ball valve during the period of its opening so as to maximize the flow of hydraulic fluid through the bi-stable valve and minimize the time required to relieve the pressure in the high pressure hydraulic system of the compression relief engine brake. The damping means comprises a spring controlled ball valve guide which inhibits premature reseating of the bi-stable ball valve and maximizes the average opening of the valve during its operating period.
