Abstract
A heating system for heating the oil of a machine having a hydraulic or lubricating oil system includes a high-pressure supply pump and a throttling element for heating the medium while reducing the pressure, the pump supplying the lubricating points of the machine at the reduced pressure either via the pressure-reducing element or via a by-pass thereto with a low flow resistance. Heat removed from the heating medium by a heat exchanger may be transferred to the service cabin of the machine for space heating purposes.
