Abstract
A drive unit for a compressor which is used in a heat pump. The drive unit includes a fuel-injection internal combustion engine which is coupled with the compressor and a starter associated with said engine and is fed from multiphase electric power supply lines. The starter is connected to the electric power supply by means of a switch. The starter is constructed as an electromagnetic drive motor having a stator and a rotor secured to the engine crankshaft and serving at least partly as a flywheel. The coil windings on the stator are fed current from the power source.
