Definitions
- the invention relates to a lubricant valve for oil pumps of internal combustion engines to optimally provide the bearings and sliding surfaces of the motors to reduce wear with lubricant.
- valves are arranged in the lubricant circuit, downstream of the oil pump, which open as cold-start valves in the start-up phase of the engine, since cold lubricating oil has a high viscosity and so long avoid pressure spikes until the lubricating oil has heated so far that its viscosity ensures control over another arranged in the oil circuit control valve.
- This control valve is required in addition to the cold start valve in the oil circuit to ensure optimum oil pressure in continuous operation of internal combustion engines, since the used for the supply of lubricant to internal combustion oil pumps, such as gerotor or gear pumps, with increasing engine speed generate an increasing lubricant flow, ie promote more lubricant than for Lubrication of the bearings and sliding surfaces of each engine is required. Therefore, as the speed increases, the pump discharge pressure would also increase.
- the control valve located in the oil circuit of internal combustion engines now serves to ensure a nearly uniform oil pressure in the gallery over all engine speed ranges.
- control valve is described in the prior art, for example in EP 1 529 958 B1 or DE 60 2004 010 989 T2.
- This prescribed there control valve has a production and assembly technically complicated structure and a complicated component geometry.
- this design is very sensitive to dirt, so that entrained by the lubricant abrasion, or foundry sand can easily store in the control valve and under unfavorable conditions for jamming the valve piston, and thus can lead to a total failure of the scheme.
- control valve introduced in EP 1 529 958 B1 can not be used as a cold start valve.
- the invention is therefore based on the object to develop a lubricant valve for oil pumps of internal combustion engines, which eliminates the aforementioned disadvantages of the prior art, in particular the functions of a cold-start valve and a control valve combined with minimal space in itself, it is constructed so that it is insensitive to the entrained by the lubricant abrasion and / or molding sand, thereby high flow rates possible, also constructed in terms of manufacturing and assembly technology cost, and can be produced inexpensively, and beyond even in extreme conditions always robust, reliable and trouble-prone working.

- a double piston 12 consisting of a arranged in a control piston 13 cold start piston 14 which is guided linearly displaceable in a arranged in the control piston 13 cold start piston guide 15 ,
- Essential to the invention is in this context that arranged in the control piston 13 inner piston guide, the cold start piston guide 15, in which a cold start piston 14 is arranged as an inner piston, wherein the piston head 16 of the control piston 13, the cold start piston guide 15 opposite the piston rod 17 is disposed at the from Spaced piston head 16 of the control piston 13 spaced a separate piston 18 is arranged, which projects beyond the piston rod 17 in the form of a spacer rod 19. It is also characteristic that in the piston head 16 of the control piston 13, the working piston 18 adjacent the inflow bores 20, and in the cylinder wall 21 of the cold start piston guide 15 of the control piston 13, the piston head 16 adjacent the outflow holes 22 are arranged.
- the cold start piston 14 is designed as a unilaterally open, multi-stage cylinder piston, which is arranged adjacent to the guide cylinder 23 in an open in the cold start piston 15 of the control piston 13 slidably disposed guide cylinder 23 with a Federstromring Chemistry 24 and a Federstromring Chemistry Cylinder diameter smaller lock cylinder 25 is made, which with its lock cylinder jacket
- the control block 34 is arranged r arranged the furskoben 18.
- the arrangement of the invention by means of a prestressed compression spring 30, the inlet holes 20 in the control piston 13 sealing, in The control piston 13 pressed cold-start piston 14 is preferably also characterized by the fact that both the control piston 13 as well as the cold start piston 14 are made of the same material, for example steel.
- the construction according to the invention simultaneously enables the double piston 12 to be prefabricated separately together with the compression spring 30, and it can also be tested separately for its cold-starting function safety even before installation.
- valve spring chamber 31 via a damping bore 35 with the oil pan, the working chamber 33 via the pressure channel 8 with the pressure kidney 5 and the control chamber 34 via a control bore 36 to the control channel 9 are connected.
- the solution according to the invention also enables high flow rates.
- the inventive arrangement of only a few, compact, easy to manufacture, usually multifunctional assemblies in conjunction with the flow guide according to the invention, as well as the valve assembly according to the invention in the pump housing that allows the Lubricant valve according to the invention not only manufacturing technology is inexpensive to produce, but that it is very well preassembled due to the structure of the invention, tested before installation, and can be installed easily, quickly and inexpensively in the oil pump
- the lubricant valve according to the invention works because of the large pressure bearing surfaces and flow cross sections, even under very extreme conditions of use always robust, reliable and störunan stricture.
- a wear plate 37 with a passage bore 38 is arranged between the compression spring 30 and the valve seat 7 arranged in the pump housing 1.
- the wear plate 37 prevents incorporation of the compression spring 30 in the valve seat 7 of the pump housing 1.
- the arranged in the wear plate 37 passage bore 38 also allows unimpeded inflow and outflow of the lubricating oil in / from the valve chamber 31 during displacement of the cold start piston 14th
- a pressure compensation chamber 39 is arranged inside the piston head 16 of the control piston 13, which connects all inlet bores 20 arranged in the piston bottom 16 and can be completely closed by the lock cylinder cover 27 of the cold start piston.
- a drain hole 40 is arranged between the bearing 2 and the valve spring chamber 31, so that the emerging from the bearing point 2 leakage fluid is derived defined.
- FIG. 3 now shows the lubricant valve according to the invention, shown in FIGS. 1 and 2, in its control function during a cold start.
- the oil pump initially conveys the highly viscous oil and builds after some
- the assemblies of the lubricant valve according to the invention are now sized, i. the piston surfaces and the spring force of the compression spring 30 are coordinated so that at a pump pressure of 11 bar, the integrated in the lubricant valve cold start valve starts with its control function.
- the pressure on the pressure for example, to 11 bar, increased at which the integrated in the lubricant valve cold start valve to start its control function ,
- the voltage applied in the working chamber 33 builds pressure on the Einströmbohronne 20 in the pressure compensation chamber 39, which acts on the lock cylinder cover 27 of the cold start piston 14, wherein, as already explained, the compression spring 30 is dimensioned so that at a pressure of 11 bar the Cold start piston 14 moves in the cold start piston guide 15 of the cylinder 21 of the control piston 13, while the cold start chamber 32 "opens", so that the highly viscous oil from the pressure channel 8 via the working chamber 33, the inflow bores 20, the Pressure compensation chamber 39, the cold start chamber 32, via the arranged in the cylinder wall 21 of the control piston 13 outflow holes 22 can flow directly into the overflow channel 10 to the oil pan.
- the present in the inventive solution, aerodynamically favorable structure, as well as the large, available flow cross-sections cause the solution of the invention also allows greater flow rates during cold start and is insensitive to the entrained by the lubricating oil abrasion and / or foundry sand.
- the warming engine causes the lubricating oil located there to warm up and a gallery pressure builds up.
- This gallery pressure eliminates the force balance existing during the cold start, and leads to a displacement of the working piston 18, which now accommodates the normal control operation of the lubricant valve according to the invention with a warm engine as a control piston.
- FIG. 4 shows the lubricant valve shown in FIG. 1 in its control function when the engine is running warm in continuous operation.
- a gallery pressure of, for example, 4 bar and a pump pressure of, for example, 6 bar was selected.
- the pressure applied in the control channel 9 gallery pressure causes that on the trained as a diaphragm control bore 36, which absorbs pressure surges and thus decisively determines the "softness" of the control, lubricating oil enters the control chamber 34.
- This lubricating oil from the gallery acts on the control chamber 34, and thus the working piston 18 with the gallery pressure of, for example, 4 bar, so that the working piston 18, for example, in the pressure channel 8 and thus in the working chamber 33 applied pump pressure of 6 bar, by means of Piston rod 17 the control piston 13 along its piston guide 11 moves so far that it opens the overflow 10, and thus a bypass line for the "excess" volume flow directly from the pressure kidney 5 via the pressure channel 8 into the working chamber 33 and from there into the overflow 10th to the oil pan free.
- the connected to the piston 18 via the piston rod control piston 13 thus takes on the concern of a gallery pressure in the control channel 9 on its normal control operation. That is, when opening the overflow channel 10, the pressure in the cold start chamber 32 is reduced, and the shooting cylinder cover 27 is pressed by the compression spring 30, the pressure compensation chamber 39 sealingly against the piston head 16 of the control piston 13.
- the compression spring 30 presses the free end of the spacer rod 19 in the end position, i. against the screw plug.
- FIG. 5 shows the design of an oil pump for internal combustion engines shown in FIG. 1 with a lubricant valve according to the invention integrated in the pump housing when the engine is at a standstill in a design modified relative to FIG.
- the free end of the spacer rod 19 is located on the valve seat 7 of the pump housing 1, or on a between spacer rod 19 and valve seat 7 arranged wear plate 37, which incorporating the free end of the spacer rod 19 in the valve seat 7 of the pump housing 1 prevents, which consists for example of aluminum.
- the compression spring 30 is applied to a locking screw.
- a lubricant valve for oil pumps of internal combustion engines which combines the functions of the cold start valve and the control valve in a minimal space in itself, it is constructed so that it against the entrained by the lubricant abrasion and / or Resilient sand is insensitive, thereby enabling high flow rates, also constructed in terms of manufacturing and assembly technology cost, and can be produced inexpensively, and beyond Even under extreme operating conditions, it is always robust, reliable and immune to interference.
