Abstract

A heat generator suitable for heating the cab or passenger compartment of a motorized automobile vehicle comprises an enclosure inside which are mechanical friction means adapted to be driven by the motor of the vehicle. These friction means are operable with a variable clamping force. A heat transfer liquid is circulated through this enclosure. The clamping force of the friction means is varied in inverse proportion to the speed at which friction means are driven by the motor. Thus the clamping force on the friction means is reduced as the motor speed increases, so that the quantity of heat produced is largely independent of the rotation speed of the motor.
