STIRLING ENGINE AND METHODS OF OPERATION AND USE

摘要

A double acting, miller cycle, reciprocating piston with dual rotary displacer, stirling engine is provided. Configurable as a heat pump, a heat engine, or as a combination with one side driving the other, the engine is completely closed, sealed and pressurized with the piston ring as the only internal seal. A miller cycle is created by allowing transfer of the working fluid (typically hydrogen gas) past the piston to balance working fluid pressure only at the extremes of the piston stroke. Two coordinated rotating displacers service opposite sides of one piston. Each displacer manages heat flow, according it its length and shape, through one side of the length of its encasing tube into and out of the working fluid through the other side of the length of its encasing tube. The dead space between the piston and the displacer holds regenerator material.

主权项

1. A double acting stirling engine in which a working fluid exerts force against a reciprocating piston comprising:
an elongated cylindrical heat exchanger connected at right angle, through regenerator material, to the piston cylinder with an elongated rotating displacer, of such mass as to serve as a flywheel, inside said heat exchanger, coordinated with said piston, that moves said working fluid from the heat input side, at which time said working fluid expands and exerts an increase of force on said piston, to the heat extraction side, where said working fluid contracts and reduces the pressure exerted upon said piston, thus completing one cycle while a similar though not necessarily identical heat exchanger and displacer perform the same sequence against the second side of said piston 180 degrees out of phase such that each direction of said piston is productive with said parts arranged according to FIG. 1.
