Abstract
A heat recovery device may include a circuit. During operation of the heat recovery device, a working medium may circulate. The circuit may include a conveyor to convey the working medium. An evaporator may be arranged downstream of the conveyor and may evaporate the working medium. An expander may be arranged downstream of the evaporator and may expand the working medium. The expander may have a shaft that may pick up a torque at the expander. A condenser may be arranged downstream of the expander and may condense the working medium. A tank may be connected to the circuit. The tank may define a volume for the working medium. An adjustor may change the volume of the tank for the working medium. A non-return valve may be arranged between the tank and the condenser, and may prevent a flow of the working medium in a direction of the condenser.
