Abstract: A cam switch assembly is actuated by movement of a member, such as a part of a convertible top that is pivoted about a first pivot axis toward and away from a surface that is fixed relative to the pivot. The cam switch comprises a holder for at least one switch that is attached to the member. A cam switch actuator having an arm is attached to the holder at a second pivot axis. The cam switch actuator opens and closes the switch as the cam switch actuator is pivoted relative to the holder about the second pivot axis. The arm has a first lost motion connection to the movable member in a first direction. The member has a second lost motion connection at the first pivot axis that is aligned with the first direction when the member is moved into engagement with the surface. The member is movable relative to the surface in a first direction and the arm is permitted to move relative to the surface without changing the angular orientation of the cam switch actuator relative to the holder.

Abstract: A marine engine tilt and trim unit having a trim cylinder with a polymer ball bearing seat. The polymer seat reduced chatter during trim operations.

Abstract: A vehicle convertible top is moved by hydraulic cylinders between extreme raised and lowered positions. The cylinder ends are connected to ports in a reversible hydraulic pump in one end of an elongated housing, which has a reservoir in the other end, separated by a pump cap. The pump cap houses two fluid circuits connecting the pump to the ends of the cylinders. Each circuit has an end of cycle hydraulic locking device comprising a normally-closed valve and a valve actuator. The circuit valves are alternately opened by pump pressure to pressurize one end of the cylinders to alternately raise and lower the top. The opened valve closes when the pump ceases operation, preventing fluid backflow through the one circuit to the pump. This hydraulically locks the top in extreme raised and lowered positions to facilitate top latching and tonneau installation.

Abstract: A vehicle convertible top has hydraulic cylinders for moving the top between extreme raised and lowered positions. The cylinders each have a pair of fluid translating ports each connected to ports in an elongated housing. A reversible hydraulic pump is in one end of the housing, while a reservoir is in the other end, separated by a pump cap. The pump cap houses two fluid circuits each connected to a housing port and each including an end of cycle hydraulic locking device which comprises a normally-closed valve and a valve actuator in each circuit. In one direction of pump operation, one of the valves is opened by pressure fluid in the one circuit to enable the outflow of the pressure fluid to the cylinders. The other valve is forced open by its actuator, in response to pressure in the one circuit, to enable the return flow of fluid to the pump through the other circuit. The one valve closes when the pump ceases operation, preventing fluid backflow through the one circuit to the pump.
