Abstract
A Stirling cycle engine having its cylinders ganged together by connecting through a cross connect passage and valve the cold variable volume chamber of one cylinder with the compression chamber of a cylinder in which the displacer piston and the power piston are ninety degrees (90.degree.) out-of-phase with the pistons in the first cylinder. The displacer piston and power piston in each cylinder are connected by a sealed piston rod so that the two pistons move in unison. Each cylinder's power piston is connected by means of a connecting rod to a means for converting the reciprocating motion of the power piston into rotational motion. Each cross connect passage is provided with a valve which allows a working fluid to pass from the cold variable volume chamber of one cylinder to the compression chamber of any cylinder which is ninety degrees (90.degree.) out-of-phase with the displacer piston of the first cylinder. This valving feature allows the engine to be reversed and throttled. Each displacer cylinder is provided with an annular groove regenerator which is adapted to accept a thermally conductive material for conducting heat to and from the working fluid thereby operating in th…
