Abstract
A two piston Stirling engine which includes a heat exchanger arrangement placing the cooler and regenerator directly adjacent the compression space for minimal cold duct volume; a sealing arrangement which eliminates the need for piston seals, crossheads and piston rods; and a simplified power control system.
Claims3
A Stirling cycle engine comprising:
- a compression piston reciprocal in a cold compression space and an expansion piston operated from a common crank shaft reciprocal in an expansion space out of phase with respect to each other;
- said pistons reciprocating along axes which are angularly disposed to one another, such that a V-configuration engine is formed;
- cooling means;
- regenerator means;
- said regenerator means being positioned immediately adjacent the cooling means;
- said cooling means being axially aligned immediately adjacent the cold compression piston so as to minimize cold duct volume;
- and heating means coupled with said regenerator and said expansion space completing the Stirling cycle.
