Device for amplifying the output of a driven machine

Stirling engine

A membrane concentrator mirror comprises a rigid, circular-segment-shaped frame-like basic body with a hermetically closed bottom wall, the basic body having a union device for connection with a conduit leading to a device for generating sub-pressure, a membrane being hermetically stretched over the basic body in such a way that it is deformable under the influence of a sub-pressure, and this membrane consisting of a plurality of membrane segments the outer end of which is limited in a circular segment shape, the membrane segments being connected with one another along radially extending rims. An improvement of the optical quality and a reliable connection of different membrane sections is to be achieved. To this effect the membrane segments are connected with one another in such a way that rigid, radially extending clamping profiles secure the radially extending outer rims by means of clamping devices.

In the case of a heat engine, in particular a Stirling engine, comprising a displacement piston and a working piston which are coupled together in a housing sealed in a leak-proof manner against the outside so that they can oscillate in a linear direction, in which case the gas space between the displacement piston and the working piston is connected to the gas space between the displacement piston and the housing by way of a heater, a cooler and a regenerator arrangement to which an external source of heat may be connected, in order to make possible the take-off of mechanical energy from the closed housing for external use, provision is made for one magnetic or magnetizable coupling device (9, 15) located within the housing (1) to be connected at least with the working piston (2) and there is also a corresponding magnetic or magnetizable coupling device (8, 18) outside the housing (1) which is movably mounted in parallel with the piston travel.
