    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.

    The heat exchanger 5 may be either water-oil or air-oil, and an additional heat exchanger may be air-oil, placed in the control cabin or the cabin of the vehicle for heating.
    The heating device (FIG. 3) contains an additional heat exchanger 10 connected to the engine oil pipe 4 in parallel between the main heat exchanger 5 with the first bypass 6 and the lubrication points 8 and equipped with an additional drain pipe 23 and an oil distribution valve 24 installed in it coming through the pipeline 23. In the line between the connection point 25 and the additional heat exchanger 10
    5, throttle element 26 is placed. The additional heat exchanger 10 is equipped with an air-oil 1m.
    A heating device (Fig. 4) for an air-cooled engine, in which the main heat exchanger 5 is filled with air-oil and is used to heat the interior of the car.
    The device is equipped with an element 27
    5 of adjusting the air between the hot air duct 28 and the exhaust duct 29.
    The heating device operates as follows (Fig. 1).
    0 Lubricating oil supplied by the oil pumping pump 2 through the suction pipe from the crankcase 1 filled with lubricating oil of the internal combustion engine with water cooling, is fed through the pressure reducing element 3 or via the bypass control control 12 via the main 4 to the lubricating points 8 of the internal combustion engine . Due to the high-pressure pump 2, the lubricating oil is compressed to a pressure of about 150 bar, and thereafter, with the release of heat, the pressure is released in the first pressure lowering element 3. The pressure level required for the lubrication points 8 is achieved by setting 1 in the oil line 4 branch of the second pressure reducing element 14, whereby the lubricating oil can be sent directly to the oil crankcase 1 of the engine
    A third pressure reducing element 15 is installed behind the lubrication points 8 in the main oil line 4 with a lower pressure level than that of the element 14. From the branch with the element 14, the lubricating oil can flow to the lubricating points of the internal combustion engine or through the oil / water main heat exchanger 5 or through the bypass 6, which is provided with the control body 7. The main heat exchanger 5 is in communication with the lubrication system of an internal combustion engine. The cooling water is pumped by the cooling water pump 17 and flows through the heat exchanger 5 and the supply line to the internal combustion engine block provided with cooling water tanks 18. Through the return duct, it enters the circulation radiator 19 washed by cooling air, and from there again to the cooling water pump 17.
    The radiator 19 has a bypass pipe 20 controlled by a thermostatic valve 21, so that the radiator 19 can be bypassed predominantly depending on the cooling water temperature due to the bypass pipe 20. Subsequently, the cooling water of the internal combustion engine serves as the heat carrier of the additional heat exchanger 10 for heating air for heating the passenger compartment. Additional heat exchanger 10 is installed in the bypass pipe parallel to the radiator 9 and the bypass pipe 20 and is connected to the return and supply pipe of the heating device - (Fig. 2). The lubricating oil comes after a branch equipped with the second pressure reducing element 14, or directly to the oil-air additional heat exchange.

    Nick 10 for heating the passenger compartment of the car and accordingly for cooling the return oil or through the bypass conduit controlled by the third control member 22 can flow to the lubrication points 8 of the internal combustion engine.
    An oil or air main heat exchanger 5 installed in the main oil line 4 can be bypassed via bypass 6 which is under the control of the first control unit 7. In this case, the additional heat exchanger 10 is filled with lubricant oil only when heating of the driver's cabin is required. In all other cases, the lubricating oil is supplied to the lubrication points 8 of the internal combustion engine through the third bypass and the third control element 22. As additional cooling of the lubricating oil is required, element 7 directs lubricating oil to the main heat exchanger 5, where it receives additional cooling.
    An exemplary embodiment of the heating device according to FIG. 3 is identical to the exemplary embodiment of FIG. 2. After element 7, the main oil on line 4 is connected directly to the lubricating points 8 of the internal combustion engine and to the third, lower pressure element 15 associated with them. However, in front of the lubrication points 8 of the internal combustion engine, the lubricating oil can fill the oil-air secondary heat exchanger 10 through the throttle element 26. This bypass oil pipeline is controlled by the distribution valve 24, so that the lubricating oil flowing through the bypass oil pipeline , can almost without pressure flow back through the drain pipe 23 into the crankcase. The oil-air supplementary heat exchanger 10 installed in the bypass pipe serves to heat the air that heats the interior of the car. Moreover, the lubricating oil, directed in front of the lubrication points into the branch and having a pressure of five or six bar, necessary for supplying the internal combustion engine with lubricating oil, further releases the pressure in the throttle valve.
    element 26 bypass pipeline with heat. In this case, the heat can be additionally used in an additional oil-air heat exchanger 10 for heating the driver's cabin,
    In the heating device (FIG. 4), the heated lubricating oil can flow after branching with element 14 through the main oil line 4, the oil-water heat exchanger 5 mine, to the lubricating currents 8 of the internal combustion engine. In addition, the heated oil can give off the heat needed to heat the car’s cabin air in the oil-air heat exchanger 5. In addition, the cabin air is supplied by the fan through the oil-air heat exchanger 5 and through the air regulation element 27 is sent to the environment or through the heating channel 28 to the passenger compartment of the car or through the exhaust channel 29. Thus, thanks to the air regulation element 27, it is possible to use an oil-and-oil heat exchanger 5 at the same time for cooling reverse lubricating oil and in order to heat the interior of the car. Since interior heating or cooling of lubricating oil is not necessary, lubricating oil is directed through bypass 6 directly to the lubricating points of the internal combustion engine, which is preferable to quickly heat the lubricating oil, in particular, immediately after starting the engine.
