Definitions

  • the present invention relates to an oil pan for a motor vehicle engine.
  • the invention finds a particularly advantageous application in the field of lubrication of motor vehicle engines.
  • the object of the invention is to increase the mileage traveled between two emptying of the engine oil circuit without this increase deteriorating the lubricating qualities of the oil used.
  • one solution consists in increasing the quantity of oil circulating in the engine. For this purpose, one can consider increasing the size of the oil pan.
  • the volume available for this purpose is limited by the environment of the engine, namely the ground clearance, other engine functions and accessories, as well as the deflections of the connecting rods and crankshaft that do not allow to increase the level of the engine. at the risk of sparging and emulsion formation.
  • This known device however, has the disadvantage of requiring a bypass circuit which, by hypothesis, reduces the amount of oil reserved for the actual lubrication.
  • this circuit is complex since it implements many ducts, nozzles, shut-off valves, calibrated valves, etc.
  • the technical problem to be solved by the object of the present invention is to propose an oil tank for a motor vehicle engine. which would make it possible very simply and at low cost the desired increase in the amount of lubricating oil of the engine.
  • said oil tank comprises a main tank fed by oil return from the low engine, and at least one additional tank fed by oil return from the top engine and comprising oil transfer means to said main tank.
  • the oil tank according to the invention consists of at least two compartments which can be contiguous, and not distant as in the known device described above. It is, on the one hand, the main tank, equivalent to the bowl usually present in a motor vehicle engine, and whose volume is limited by the travel of the rods, and, secondly, at least one tank complementary located in the available volumes close to the main tank, apart from the travel of the connecting rods.
  • This (these) tank (s) complement (s) allows (tent) to substantially increase the usable oil volume while forming at lower cost a single compact oil tank compact. The volume increase thus obtained can reach 50% or more.
  • the oil tank according to the invention does not require any supply of the additional tank by sampling on the main circuit. There is therefore no need for conduits, valves, valves, or miscellaneous accessories, which represents a great simplification of implementation and a significant saving compared to the known device of the state of the art.
  • said oil transfer means is constituted by an overflow device.
  • the additional reservoir is fed by a conduit opening substantially in the bottom of said complementary reservoir.
  • Figure 1 is a sectional view of an oil tank according to the invention.
  • Figure 2 is a perspective view of the oil tank of Figure 1.
  • the invention is not limited to the presence of a single complementary reservoir, but that it can also implement a plurality of complementary reservoirs arranged between them so as to make best use of the available volumes. near the main reservoir.
