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.
Claims12
In an internal combustion engine having an oil distribution system normally operable at a predetermined pressure level, said system including a main oil conduit, a pump for suctioning oil from an oil sump of the engine and feeding the oil to oil distributing points or galleries of said oil distribution system, an oil heating system comprising solely said oil distribution system wherein said pump comprises a high-pressure pump producing a pressure of about one order of magnitude higher than said predetermined level, a pressure-reducing element in said conduit between said pump and said oil distributing points for reducing the oil pressure flowing therethrough and thereby increasing the oil temperature before the oil reaches said oil distributing points or galleries of said oil distribution system.
