ABSTRACT:
A system for heating the operator's cabin of a machine powered by an internal combustion engine includes a primary oil conduit system wholly contained within the oil pan of the machine and having a high-pressure pump for feeding oil under heat and high pressure from the oil reservoir and back thereinto through a throttling element for heating the oil as it passes therethrough. A secondary oil conduit system operating under a pressure less than that of the primary system has an intermediate heat exchanger in heat exchange relationship with the oil heated by the first system, and has a heating heat exchanger located in the operator's cabin for supplying heat thereto. The secondary circuit contains liquid which is circulated by a circulating pump.
