Abstract
In a hydrodynamic heat generator for a motor vehicle with an internal combustion engine having a cooling water circuit with a circulating pump, the hydrodynamic heat generator comprises a generator housing part which is integrated with a pump housing part and defines a water space which is in communication with the pumping space and includes a bladed rotor and a bladed stator firmly supported in the generator housing part adjacent the water space and an electromagnetic clutch for engagement of the bladed rotor with a drive shaft which extends through the heat generator housing part into the pump housing part and carries, at its end in the pump housing part, an impeller for circulating the cooling water.
Claims5
A hydrodynamic heat generator for a motor vehicle with an internal combustion engine having a cooling water circuit with a water circulating pump having a pump drive shaft driven by said internal combustion engine and including a pump housing part to be mounted on said engine, said hydrodynamic heat generator comprising a generator housing part integrated with said pump housing part and defining a generator water space, said housing parts including passages providing for communication between said pump and said generator water space, a pump impeller mounted on said drive shaft in said pump housing part, a bladed stator firmly supported in said generator water space, a bladed rotor rotatably supported in said water space adjacent said stator, and an electromagnetic clutch also arranged in said generator water space for engagement of said bladed rotor for rotation with said drive shaft when the cooling water temperature is insufficient.
