Mechanical engine driven water pump

Abstract

A mechanical engine driven water pump is disclosed for converting energy from an input heat source to a reciprocating mechanical output for powering the water pump. The mechanical reciprocating engine comprises an engine bore having an input port and an output port. An engine piston is disposed in the engine bore. An engine valve assembly is slidably mounted to the engine piston for communicating the input port and the output port with opposed sides of the engine piston for effecting reciprocal motion of the engine piston. A piston shaft is connected to the reciprocal motion of the engine piston to provide the reciprocating mechanical output the water pump. A stuffing box is interposed between the mechanical reciprocating engine and the reciprocating mechanical output for providing a positive seal for the mechanical reciprocating engine. The heat source may comprise a solar heat source, a geothermal heat source, a byproduct heat source or the external burning of a petroleum product.
