Abstract
The invention concerns a contraction engine or pump comprising two mutually spaced rigid elements (4, 6) connected to each other by at least one piston/cylinder system (8, 10) receiving an operational medium and of which at least one element is displaceable in the direction of motion of the piston/cylinder system. At least one expansible and contractile operational element (11) is connected to the two elements (4, 6) and is operationally connected with a fitting for liquid intake and exhaust and/or water vapor intake and exhaust and which will expand in the case of liquid and/or water vapor intake and will contract in the case of liquid exhaust and/or water vapor reduction. The cylinder (8) is connected to intake and exhaust conduits (12, 14) for the operational medium.
