Gas expansion units, to convert thermal energy into motor energy as a hot water motor, has closed pressure vessels with injection openings for hot and cold water, and a short circuit pipe between them for pressure compensation

摘要

The invention relates to an assembly of gas expansion elements for a device for converting thermal energy into motor energy in particular for a hot-water motor. Said assembly comprises two closed pressure containers (9, 10), which are filled with a gas or gas mixture, are actively connected to the device and have an upper injection opening (7, 8) for hot and cold water. The assembly is provided with a short-circuit pipe (11) between the two pressure containers (9, 10), said pipe comprising at least one controllable valve (12, 13) for equalising the pressure between the pressure containers (9, 10), after the gas or gas mixture has performed its work.
