Abstract

1389988 Stirling cycle engines UNITED STIRLING (SWEDEN) AB & CO KB 22 Aug 1973 39694/73 Heading F1S The invention relates to a multi-cylinder doubleacting Stirling cycle engine of the kind in which each cylinder contains a piston 34, 36 which separates a low temperature working space from a high temperature working space in the cylinder and each piston separates from each other two different charges of working gas, each piston having at least two axially spaced piston rings 38, 39. According to the invention each piston is provided with an internal cavity 37 having a volume greater than the swept volume of the cylinder and with at least one passage 40 connecting the cavity to a space at the outer surface of the piston between the two piston rings, means being provided for maintaining minimum cycle pressure in the cavity. As shown the piston rings co-operate with grooves in the piston and act as non-return valves which ensure that minimum cycle pressure is maintained in the cavity.
