ABSTRACT:
A hot gas reciprocating apparatus is disclosed in which a displacer piston and power piston operate within a cylinder due to flow of medium gas which is heated and cooled through a heater and a cooler. The cylinder is divided into a upper chamber and lower chamber by the displacer piston, and the lower chamber is defined between displacer piston and power piston. The upper chamber and lower chamber are connected with one another through the heater, a regenerator and the cooler, whereby the medium gas flows into the lower chamber from the upper chamber or vice versa. The heater, which receives heat from heat sources, projects radially from the cylinder to extend over the heat source; and the cooler projects radially from the cylinder on an opposite side from which heater extends. The heater and cooler are axially spaced from one another along the axis of the cylinder. Thus, a high temperature difference between the heater and cooler is obtained to accomplish highly efficient operation of the hot gas reciprocating apparatus.
