ABSTRACT:
A heater for heating liquid by friction includes a rotor rotatable within a housing filled with liquid, the rotor having passages arranged to expel liquid through friction orifices by centrifugal force from a pair of inlet cavities on opposite sides of the rotor. The outlets of the passages lie in a common plane on the periphery of the rotor whereas the inlets of alternate passages open alternately into the respective inlet cavities. The housing has a plurality of outlets lying in the plane of the rotor outlets with one of the housing outlets leading to a heat utilization device while the other housing outlets are connected to by-pass passages leading back into the housing through the side or sides thereof. The constant in-flow from the by-pass passages virtually eliminates cavitation while the pre-heated liquid in the passages adds to the heat of the liquid in the housing otherwise frictionally heated by rotation of the rotor.
