ABSTRACT:
A pressure relief device for a throttle-type engine exhaust suppressor comprises a valve bore opening into the exhaust pipe in the region of an end face of the throttle valve when the throttle valve is in closed position. The valve bore incorporates a spring loaded valve poppet. When a predetermined back pressure is established in the exhaust pipe, the valve poppet opens against the spring pressure and provides a bypass around the throttle valve.
