Abstract
A piston type power plant operable by any suitable pressure fluid available such as natural gas from a well for stationary applications, etc., or by compressed air in either stationary or mobile applications such as driving generators, saw mills or vehicles, etc., and embodying novel valve actuation and control means.
Claims4
A power plant adapted to have its pistons and its valves operated by a pressure fluid comprising, in combination;
- a piston and cylinder type engine having a drive shaft rotatable by the reciprocating pistons;
- and inlet manifold connected to a source of pressure fluid and an exhaust manifold;
- a unitary inlet and exhaust valve means positioned between and connected to each cylinder and said manifolds;
- timing means including a pressure fluid distributor connected to each of said unitary valve means for admitting pressure fluid thereto to move it cyclically to inlet position for admitting pressure fluid to said cylinders to reciprocate said pistons;
- and spring means for returning each of said unitary valve means to exhaust position upon the completion of each of said piston's working stroke.
