Mitral Valve
The valve
The function of back pressure valve is to prevent back flow to the pump in case there is an obstruction on downstream side of valve.
because the inlet valve has to hold back pressure from the gas pump where as the exhaust valve has nothing to hold back but the compression of the ignited fuel and such a force is applied at the face of the valve. the face of the valve is in the cylinder so the force is a push not a pull meaning a bigger exhaust valve is not needed because the valve dose not have to fight back to keep it's self closed.
