A temperature difference pump has a stainless steel container provided with an inlet and outlet; on both sides is positioned a direction-of-flow determining device, such as a non-return valve, and both valves are positioned in the main direction of flow. The insulation encloses the stainless ...
The non-return valve and the thermostat valve are provided in respective lines (16, 17), which are branched from the supply line. The non-return valve allows a flow only from a direction of the supply line. A switching element (20) i.e. expansion element, controls the thermostat valve ...
Non-return valve for e.g. determining direction of flow of fluid within pipes for supercharged engine for tank regeneration of motor car, has venturi nozzle with two conical recesses, which are formed in valve housing or in part of housing...
