Abstract:
An exhaust valve arrangement includes a cylinder having a top end, an exhaust conduit connected to the cylinder by an opening in the top end of the cylinder, the opening comprising a valve seat, a valve member comprising a valve stem and a valve head on the valve stem, the valve member being movable between a closed position in which the valve head is received in the valve seat and an open position in which the valve head is spaced from the valve seat, and a resilient member arranged to urge the valve member to a closed position. A piston is mounted relative to the valve stem, the piston being disposed in a second cylinder in flow communication with the exhaust conduit and arranged such that a change in pressure in the exhaust conduit changes a degree of compression of the resilient member.
