ABSTRACT:
A hydraulic circuit for a tilt and trim unit of a marine outboard drive including an improved relief valve that has application in other uses. The relief valve includes a movable valve seat member and a movable valve member and the valve member is urged by the fluid pressure to be relieved into engagement with the valve seat member so that the seating pressure increases as the fluid pressure increases. When the set pressure is reached, the valve seat member is permitted to move away from the valve member, which is then held by a stop, so as to provide pressure relief.
