Abstract
A driving apparatus for a Stirling cycle engine is disclosed. The engine has a diaphragm on a rod connecting each compression piston and a driving mechanism. The diaphragm separates a space of the compression piston back pressure side and a driving chamber. A crank axle has at least one crank pin with two compression pistons connected to the crank pin of the crank axle. The pistons are located on opposite sides of the crank axle. The diaphragms of the two compression pistons perform the capacity change of the piston back pressure sides 180.degree. out of phase relative to one another.
Claims7
In a Stirling engine, a driving apparatus comprising:
- at least two compression pistons;
- a driving mechanims for each compression piston;
- a rod interconnecting each compression piston with its respective driving mechanism;
- a diaphragm on each rod closing off a space of the compression piston back pressure side and permitting a change in the volumetric capacity of the space, means for releasing pressure from the spaces of the compression piston back pressure sides;
- and
- a crank axle having at least one crank pin, the at least two compression pistons being connected to a common one of said crank pins of said crank axle and located on opposite sides of said crank axle, said diaphragm of the two compression pistons changing the volumetric capacity of the piston back pressure sides 180.degree. out of phase relative to one another.
