Definitions

  • the invention relates to an internal combustion engine according to the preamble of the first claim.
  • DE-OS 28 25 870 describes an internal combustion engine with a cooling oil and lubricating oil circuit connected in parallel, both circuits being acted upon by a common oil pump.
  • a heat exchanger oil cooler
  • This bypass line is controlled by a thermostatic valve, which directs the oil through the oil cooler from a certain oil temperature and below it through the bypass. So that the lubricating oil circuit is primarily supplied with oil when the oil pressure is too low, a priority valve is arranged in the cooling oil circuit, which only allows passage through the cooling oil circuit above a certain oil pressure.
  • thermostatic valve in a bypass line of the heat exchanger, as described in DE-OS 28 25 870, is intended to conduct the oil through the bypass line at low temperatures.
  • the object of the invention is, while avoiding the disadvantage just mentioned, to equalize the oil pressure in an internal combustion engine upstream of the heat exchangers with simple means, so that it is almost independent of the oil temperature.
  • the throttle is advantageously arranged in the flow direction in front of the first point of the internal combustion engine to be cooled, in order to ensure that the entire internal combustion engine is heated.
  • a simple, inexpensive embodiment of the throttle is to design it as a bore in the housing of the internal combustion engine.
  • a priority valve is arranged in the cooling oil circuit, which consists of a spring-loaded piston guided in a bushing.
  • the throttle is advantageously integrated into the priority valve, a gap being expediently arranged between the piston and the bushing through which the cooling oil flows when the valve is open.
  • Fig. 1 shows an oil circuit of an internal combustion engine, wherein the cooling oil and lubricating oil circuit 5, 6 are acted upon by a common oil pump 3.
  • a pressure relief valve 4 is arranged, which controls the discharge into an oil return line 18 and thereby limits the maximum oil pressure.
  • the oil delivered by the oil pump 3 is divided into two partial flows, one of which forms the cooling oil circuit 5 and the other the lubricating oil circuit 6.
  • An oil filter 8 is arranged upstream of this in the flow direction so that only cleaned oil enters the motor 7 in the lubricating oil circuit 6.
  • a priority valve 9 is installed in the cooling oil circuit 5, which has the task of supplying the lubricating oil circuit 6 primarily with oil.
  • a throttle 2 is arranged in the cooling oil circuit 5, two heat exchangers, namely an engine oil cooler 10 and a heater 11, being arranged in the flow direction behind the engine 7 in front of an oil holding valve 12.
  • the engine oil cooler 10 is controlled by a thermostat 13, which only releases the flow through the engine oil cooler 10 at a certain predeterminable temperature of the oil.
  • the heater 11 is located downstream of the engine oil cooler 10, a heater valve 14 also enabling or blocking the flow to the heater 11.
  • a control valve 15 is arranged in the inflow thereof, which regulates a bypass 16 to the heater 11.
  • the oil pressure upstream of the heat exchangers is equalized by the throttle 2 and the risk of the heat exchangers bursting is thereby reduced.
  • Fig. 2 shows the same arrangement of the cooling oil circuit as shown in Fig. 1, only the cooling oil circuit is acted upon by a separate oil pump 17.
  • the priority valve 9 shows a priority valve 9 with an integrated throttle for installation in the cooling oil circuit of an internal combustion engine.
  • the priority valve 9 consists of a bushing 19 with a valve inlet 22 and valve outlet 23, a piston 20 loaded by a spring 24 being guided in the bushing 19.
  • a gap 21, which is designed as a throttle is arranged between the piston 20 and the bushing 19.
  • the piston 20, held by the spring 24 sits sealingly on a valve seat 25 at the valve inlet 22 and thereby blocks it.
  • the piston 20 is moved against the spring force in the bushing 19 and the oil flows through the valve inlet 22 through the gap 21, i. H. the throttle into the valve outlet 23.
  • the arrows in FIG. 3 represent the flow of the oil in the open state of the priority valve 9.
  • throttle cross section is selected in a suitable manner, only a temperature-dependent amount of oil will pass through the throttle, while the other part of the oil is available for other purposes.
  • a throttle therefore equalizes the oil pressure upstream of the heat exchangers by reducing the flow rate, in contrast to a thermostatic valve, which blocks the oil flow through the heat exchanger below a certain temperature and thereby causes the oil pressure in the heat exchanger to drop abruptly.
