Waste heat utilization system for internal combustion engine of motor car, has setting unit comprising actuator that adjusts stroke of adjustable piston arranged within cylinder that encloses balancing chamber of pressure reservoir

摘要

The system has a waste heat utilization circuit (19) in which working fluid (20) is circulated. A conveying device (22) drives the working fluid in the flow direction (21). A vaporizer vaporizes the working fluid. A pressure reservoir (33) incorporates a balancing chamber (34) that is filled with the working fluid and fluidly attached to the waste heat utilization circuit. The pressure reservoir includes a cylinder that encloses the balancing chamber. A setting unit (35) comprises an actuator that adjusts stroke of an adjustable piston arranged within the cylinder.
