Abstract
Stirling engine which may be used as a heat pump, which consists of a hot half and a cold half. Both halves are connected by two lines which constitute a counterflow heat exahnger or in which a counterflow heat exchanger is mounted. Moreover, a mutual shaft, to which in the hot half a large and a small piston are mounted and to which in the cold half a large and a small piston are mounted, connects both parts. For every up or down going movement of the shaft, a complete Stirling cycle is performed. If desired, the shaft may be replaced by a hydraulic interconnection.
Claims6
A Stirling motor comprising:
- a hot motor part comprising,
- a first pair of mutually coupled pistons, including a first large piston and a first small piston which are movable in a reciprocal manner, and
- a first assembly including a first large cylinder and a first small cylinder in which said first large piston and said first small piston respectively move, wherein said first assembly is configured to allow fluid to be exchanged between the first small cylinder and the first large cylinder;
- a cold motor part comprising,
- a second pair of mutually coupled pistons, including a second large piston and a second small piston which are movable in a reciprocal manner, and
- a second assembly including a second large cylinder and a second small cylinder in which said second large piston and said second small piston respectively move, wherein said second assembly is configured to allow fluid to be exchanged between the second small cylinder and the second large cylinder;
- a shaft or a hydraulic interconnection connecting the hot motor part and the cold motor part;
- and
- a counterflow heat exchanger coupled to said hot and cold motor parts by two tubes so as to mutually thermally interconnect the first large cylinder in said hot motor part with the second large cylinder in said cold motor part, and the second small cylinder in said hot motor part to the second small cylinder in said cold motor part.
