ABSTRACT:
A high-speed steam admission poppet valve structure in a steam engine employs a low-inertia valve element spring-biased into seated position in a valve seat in the end wall of a cylinder and employs a valve lifter member fixed to the face of the associated piston for cyclically unseating the valve element, the lifter member and the valve element having cooperable engageable surfaces of conforming configuration which are maintained in engagement in both the unseating and seating of the valve element for maintaining the sealing surface of the valve element both parallel to and centered in relation to the valve seat in the seating of the valve element.
The clearance volume of the cylinder may be adjusted manually or automatically to regulate the power output and efficiency of the engine.
