Abstract:
The invention concerns a self-powered remote control device comprising transmitting means (8, 9, 10), a feeder circuit (6, 7) connected to said transmitting means, a generator supplying electric power connected to the feeder circuit, and control means (3) associated with the electric power generator. The generator comprises at least a piezoelectric element (1) receiving mechanical stresses produced by actuating the control means and supplying electric power to the feeder circuit. The invention also concerns an apparatus comprising at least a self-contained control device actuated by a mechanical action member (4, 52). The invention further concerns an electric installation comprising means for receiving signals transmitted by at least a self- powered control device.
Abstract:
A rotary piston machine includes a first spheroidal element (10) including pistons (18) and/or cylinders and a second spheroidal element (16) including pistons and/or cylinders (19), wherein the first element (10) can move relative to the second element (16). The machine can be used as part of a pump, compressor, or engine.
