Abstract
A heat recovery apparatus having a circuit that during operation circulates a working medium. The circuit may include an evaporator to evaporate the working medium, an expander arranged downstream of the evaporator to expand the working medium, and a condenser arranged downstream of the expander configured to condense the working medium. The expander may include a shaft to draw a torque at the expander. An injector pump may drive the working medium. The injector pump may include a driving fluid inlet, a suction inlet, and an injector outlet. The driving fluid inlet may be fluidically connected to the circuit between the evaporator and the expander. The suction inlet may be fluidically connected to the circuit between the condenser and the evaporator. The injector outlet may be fluidically connected to the circuit between the suction inlet and the evaporator.
