Definitions
- the invention relates to a pump, for example for pumping lubricating oil of an internal combustion engine, in particular a multi-stroke vane pump, in which the rotating group comprises a rotor with at least radially movable vanes, a stroke contour on which the vanes with their wing heads slide sealingly, and two axial side covers, such as side plates or housing walls.
- Such pumps are known. They have axial inlet openings and outlet openings in their side plates, which must be separated according to their pressure ranges, for example by sealing devices or the like, and therefore cause a large axial overall length in vane pumps of this type.
- the components of the known rotation groups such as. B. side plates made of sintered steel and contour rings made of solid steel or sintered steel, correspondingly thick-walled and thus require both a large radial and axial space.
- a pump for example for conveying lubricating oil of an internal combustion engine, in particular a multi-stroke vane pump, in which the rotary group has a rotor with at least radially movable vanes, a stroke contour on which the vanes with their wing heads slide sealingly, and two axial side covers , such as side plates or housing walls, wherein the stroke contour and a first axial side plate are represented by a sheet steel pot.
- the tin pot can preferably be produced by deep drawing.
- a pump is preferred in which a second axial side plate is represented by a sheet steel cover.
- a pump according to the invention is characterized in that the sheet metal cover has an embossed shoulder, the outer contour of which has the shape of the stroke contour.
- the sheet metal cover after insertion in the tin pot covers the rounding of the tin pot, which is caused by the deep-drawing process, and thus creates tight sealing gaps within the rotating group.
- the sheet metal cover can be produced by fine stamping or fine cutting.
- a pump according to the invention is characterized in that the suction openings are represented by radial openings in the tin pot.
- the rotary group has a narrow construction, since the suction channel can be arranged radially around the tin pot and does not have to be arranged axially on the opposite side of the pressure channel.
- a pump is also preferred in which the outlet openings are represented by axial openings (pressure kidneys) and optionally at least one radial opening in the tin pot.
- the radial outlet opening can be closed by a temperature switching valve or a pressure switching valve and thus creates a switchable delivery area.
- a pump according to the invention is characterized in that the temperature switching valve has an overtravel spring. This has the advantage that after the radial outlet opening is closed by the temperature switching valve, if there is a further expansion of a thermal expansion element due to an increase in the temperature of the
- the expansion element can perform an additional expansion path against the overtravel spring without deformation or destruction.
- a pump is preferred in which the tin pot of the rotating group and, if appropriate, the temperature switching valve or pressure switching valve are integrated in a plastic housing.
- the plastic housing is preferably injection molded and therefore does not require any post-processing. The advantage is that a rotary group encapsulated in sheet metal is integrated in a plastic housing and the advantages of the two types of material can thus be exploited.
- Another pump according to the invention is characterized in that the axial outlet opening of the switchable delivery area can be closed by a spring tongue check valve.
- the shape of the spring tongue check valve has the Shape of the stroke contour curvature.
- the spring tongue check valve is mounted on a pin made of plastic in the plastic housing. The spring check valve is also protected against overexpansion by a stroke stop in the plastic housing. This design of the spring tongue check valve has the advantages, on the one hand, of being very inexpensive and, on the other hand, of being integrated in the pump in a space-neutral manner.
- a pump according to the invention is characterized in that the tin pot has a notched or stamped cold start ring which, in the cold operating state, guides the wings outwards under the wings in accordance with the stroke contour and directs them against the stroke contour. Furthermore, a pump is preferred in which the rotor has grooves or depressions for receiving the cold start ring. A pump is also preferred in which the sheet metal cover has a notched or stamped cold start ring.
- a pump according to the invention is distinguished by the fact that the sheet metal cover has embossed sheared kidneys, that is to say pressure kidneys without through-openings, which only bring about axial pressure surface compensation for the rotor in the pressure area.
- a pump in which the radial outlet opening or openings of the switchable delivery area open into a channel that opens directly into the suction area of the second, non-switchable delivery area. This has the advantage that low flow losses and favorable ducting lead to a low-energy, pressure-free circulation of the switchable delivery area.
- Figure 1 shows a top view of the open pump.
- Figure 2 shows the section B-B of Figure 1.
- Figure 3 shows in cross section the tin pot and the rotor.
- Figure 4 shows a detail of the tin pot and the sheet metal cover.
- Figure 5 shows in cross section the rotating group and the temperature switching valve.
- Figure 6 shows in cross section the temperature switching valve in the open state.
- Figure 7 shows the pump housing with the check valve.
- FIG. 8 shows the section D-D from FIG. 7.
- FIG. 9 shows in cross section an embodiment of the cold start ring
- Figure 10 shows in cross section a further embodiment of the cold start ring
- FIG. 9 shows the section C-C from FIG. 7.
- the pump according to the invention in its housing is shown in supervision without a cover.
- the tin pot 1, in which the stroke contour is shown, contains the other parts of the rotating group such as. B. the wings 3, which are arranged in radial slots 5 slidably in the rotor 7.
- the rotor 7 has a recess 9, in which, for. B. engages the crankshaft of an internal combustion engine and thus drives the lubricating oil pump. In this case one speaks of a so-called shaft neck pump.
- the rotation group is arranged with the tin pot 1 in a plastic housing 11 and is closed by the sheet metal cover, not shown here.
- the rotation group, completely encapsulated in sheet steel, has the advantage that the friction pairings do not change here.
- the tin pot 1 is partially surrounded within the plastic housing 11 by a channel 13 which is acted upon by the suction pressure of the pump.
- the shape of the stroke contour forms two pressure areas 15.1 and 15.2, in which the cells between the wing, rotor, cam ring and side plates shrink and thus expel the pressure medium, and two suction areas 17.1 and 17.2, in which the corresponding cells enlarge and suck in medium.
- the function of such a double-stroke vane pump is known and need not be explained further here.
- a temperature switching valve 19 is arranged inside the housing, which has an expansion element within a housing 21, which can press a valve sealing plate 25 against the force of a return spring 27 against the sheet metal pot 1 via a pin 23 when the lubricating oil rises.
- the tin pot 1 In this position, not shown here, in the tin pot 1 there is a radial opening from which the pressure kidney 15.1 can deliver pressure oil into the intake duct 13 as long as the temperature switching valve remains in this open state. The oil expelled from the pressure kidney 15.1 thus passes without pressure via the channel 13 to the suction kidney 17.2 of the second pump half and is therefore sucked in by the pump without major losses.
- the tin pot 1 has one or more radial openings in the suction area of the suction kidney 17.2.
- the suction kidney 17.1 of the first pump part here has invisible radial openings in the tin cup 1 through which oil can be sucked in from the suction channel 29.
- the suction channel 29, like the suction channel 13, is connected to the suction connection 31, from which the oil from the internal combustion engine area, such as, for. B. the oil pan, can be sucked.
- the oil is then discharged through the lubricating oil pump in the pressure channel 32 and fed to the internal combustion engine under pressure via the pressure connection 34.
- a pressure relief valve is arranged in the area 36 of the plastic housing, which opens when the maximum permissible pressure in the pressure area 32 is exceeded and in turn supplies the excess oil to the suction area 29 via the outflow channel 38.
- FIG. 2 shows section B-B from FIG. 1.
- the tin pot 1 is embedded in the plastic housing 11.
- the tin pot 1 contains the rotating group and thus, among other things, the rotor 7 shown here in cross section.
- the rotating group is closed off by a sheet metal cover 40.
- the stroke contour, as shown in FIG. 1 is drawn directly into the sheet metal, and the sheet metal base 42 of the tin pot forms the first axial side plate of the rotating group.
- the cover 40 has a shoulder 44 which projects into the upper edge of the tin pot 1, which also has the shape of the stroke contour in its outer contour and which thus represents the second axial side plate of the rotating group.
- a plurality of radial openings 46 and 48 are made in the tin pot 1 in the suction area.
- the suction openings 46 and 48 open into the suction channels 29 and 13, which are shown in a top view in FIG.
- FIG 3 the design of the tin pot 1 in the plastic housing 11 and the rotor 7 is shown enlarged. It can be seen that the tin pot 1 has a rounding 50 at its upper end, which is caused by the deep-drawing process in terms of production technology.
- the rotor 7 has two grooves 52 on its side surfaces, into which a so-called cold start ring 54 engages.
- the cold start ring 54 is notched or stamped out of the tin pot 1 and also has the shape of the stroke contour on a reduced scale.
- This cold start ring thus engages within the rotor grooves 52 under the wings and lifts them along the contour so far that they slide and seal approximately on the contour ring, even if the wings are not pressed out by centrifugal forces or by additional pressure forces under the wing. This ensures that the wing heads rest securely on the contour ring even at cold starts and at low engine speeds.
- the interaction of the tin pot 1 with the sheet metal cover 40 is shown in particular. Due to the manufacturing process, the rounding 50 is caused by the deep-drawing process in the tin pot 1, but this would be problematic for the wings as a sealing surface or tread. Therefore, the sheet metal cover 40, which can be produced as a flat component with a manufacturing process other than deep drawing, has a more sharp-edged deformation of the shoulder 44, which covers the rounding 50 and thus ensures a sufficient sealing of the rotating group on the top of the rotor 7 and the wing heads , Thus, the wings are housed within the right-angled rotation group room with their side walls and their wing head in a sufficiently sealing manner.
- FIG. 5 shows a cross section of the rotating group and the temperature switching valve.
- the temperature switching valve is extended by the elevated temperature of the lubricating oil and closes an opening 56 in the pressure region with its valve body 25.
- the pressure kidney 15.1 from FIG. 1 cannot deliver into the unpressurized circulation of the channel 13 and thus feeds into the pressure channel 66 via a check valve 64, which will be described in more detail later, which means that both
- the temperature switching valve 19 is accommodated with the housing of the expansion body 21 in a separate cover 62, the expansion element housing 21 being supported on a web 60 of the cover 62 with a so-called overtravel spring 58.
- the overtravel spring 58 secures the expansion element and the housing against overexpansion by further temperature increase and expansion of the expansion element, which works as follows: First, when the temperature increases, the expansion element extends the actuating rod 23 against the force of the spring 27 and thus with the Valve body 25 close the pressure opening 56.
- the temperature switching valve is open, i.e. shown in the cooled state.
- the valve closing body 25 has moved away from the radial pressure opening 56 of the tin pot 1, and the pressure oil from the area 15.1 can now flow via the opening 56 into the channel 13 for unpressurized circulation up to the suction port 17.2 from FIG. 1.
- the spring cup 68 also serves to guide the actuating pin 23 of the temperature switching valve.
- the return spring 27 has pushed back the actuating pin and the cooled expansion element via the spring cup 68.
- FIG. 7 the rotation group has been removed from FIG. 1, so that the arrangement of the check valve 64 can be seen in an underlying pressure channel 70.
- the pressure channel 70 and the spring leaf 72 of the check valve 64 are adapted to the stroke contour, so that the spring leaf 72 of the check valve 64 can close the pressure kidney 15.1 from FIG. 1.
- the check valve 64 is mounted in the housing 11 by means of a plastic pin 74 and is fixed by the tin pot against the plastic housing after it has been inserted.
- FIG. 8 shows the section D-D from FIG. 7 and thus the stroke end stop 76 of the valve leaf 72.
- FIG. 9 shows in section C-C the plastic pin 74 which supports the spring leaf 72 in the plastic housing 11.
- FIG. 10 shows an alternative of the cold start ring 54.1 to the representation of the cold start ring 54 in FIG. 3 in cross section.
- the cold start contour 54.1 is pressed out of the tin pot 1 by means of an expression and thus engages under the wing 3, which is mounted in the cam ring 7, and thus guides the wing 3 along the stroke contour of the metal cover 1.
- FIG. 11 shows a further variant of the cold start contour 54.2, which is produced from the tin pot 1 by material displacement and can therefore also guide the wing 3 here against the contour.
- the axial tolerances of the pot depth can be eliminated if the lid 40 is pushed open in a controlled manner.
- Axial and radial openings are provided in the pressure range of the switched stage.
- the openings in the radial direction with the temperature switching valve or a pressure switching valve are used for unpressurized circulation.
- the oil is flushed out of the pressure side back into the suction chamber for the next suction stage. Due to the channeling obtained in this way, there are only minor flow losses due to deflection.
