<p>The machine has a housing (2a) which forms a chamber containing the working medium together with a heat-source (6) and sink (5). The regenerator (7) forms an intermediate heat-accumulator movable between source and sink, and the medium acts on a working piston (4). Compression movement of the piston generates medium flow from source to sink, and expansion movement flow in the reverse direction. The flow resistance offered by the regenerator causes its movement in relation to the medium. The source and skin can be situated near the piston dead-centre positions. They and the regenerator can form flat parallel components. The source can be situated between pistons and regenerator in the housing.</p> |
