Definitions
- the invention relates to a vane pump according to Preamble of claim 1.
- Vane pumps of the type mentioned here are known from DE 28 35 816 A1. You assign one Rotor on, in the peripheral wall wings receiving slots are introduced. The rotor rotates within a contour ring, the preferably forms two crescent-shaped conveying spaces, that are passed through by the wings. In the Rotation of the rotor results in bigger and smaller becoming spaces. In operation of the vane pump there are suction and pressure areas. at a contour ring of the type mentioned here there are two separate pump sections with each a suction and a pressure area.
- the side of the print area is limited on the outlet or delivery side by means of a close-fitting pressure plate and on the Conveyor side opposite side for example through the housing of the vane pump.
- the vane pump has two tight pressure plates on the rotor, with the An opening is located on the delivery side opposite the pressure plate having a fluid connection between a preferably lower pressure range and one creates a closed pressure chamber. This will a pressure built up in this pressure chamber, which the The pressure plate bends slightly towards the rotor and presses close to the rotor. The one in the funding area built up pressure leads in the same way to a Acting on the pressure plate on the conveyor side a force that pushes this pressure plate close to the rotor presses.
- the Fluid connection in the opposite of the delivery side Pressure plate a passage area that less than 1/3 of the passage area of the outlet opening the delivery-side pressure plate.
- the Invention has the closing the pressure chamber Pressure plate that has an opening for connecting the includes lower pressure area with the pressure chamber, a further relatively small opening that from Pressure room in the other overhead Print area opens.
- an opening is provided which is built in Location of the upper pressure area with the pressure chamber combines.
- the print area below is sealed by the pressure plate to the pressure chamber.
- An advantageous embodiment also consists in the pressure plate opposite the delivery side to be provided with two openings, each one Connection between a print area and the Establish pressure room and the high hydraulic Exhibit resistance. The sum of the two Resistance must exceed a value that to avoid a short circuit in the cold start phase necessary is.
- FIG. 1 For a better understanding, let's start with general based on Figure 1 on the structure of a vane pump To be received.
- This includes a housing 1, in which a channel leading to an outlet 3 is provided.
- a consumer for example a power steering device with a fluid, for example hydraulic oil.
- the housing has a circular interior 5 on which receives a contour ring 7 and a rotor 9, in the peripheral surface wing 8 receiving Slots are introduced.
- the rotor 9 is over a drive shaft 11 rotated so that the wings 8 move within the contour ring 7, whose interior 5 is designed so that two crescent-shaped, also referred to as production rooms Open spaces are formed by the wings be run through. Between two circumferentially seen - neighboring wings are so-called Vane cells when the rotor rotates get smaller and bigger. This will Suction and pressure areas formed.
- the end faces the contour ring 7 and the rotor 9 are applied Sealing surfaces on the pressure plates 17.1 and 17.2 be formed.
- the vane pump is designed so that Hydraulic oil in the pressure area to the inside of the Rotors lying undersides of the wing - the so-called Under wing area - and this with Pressure applied. Through the in the lower wing area prevailing overpressure are the wings from the Slits are pressed radially outwards and thus lie sealing on the inside of the contour ring.
- FIG. 2a shows an essentially annular groove 25 intended for the lower wing areas.
- FIG. 2b shows an essentially annular groove 25 intended for the lower wing areas.
- four independent, essentially ring segment-shaped Grooves 27 formed.
- Figure 2a shows that the kidney-shaped Pressure areas 23 of the pressure plate on the pressure chamber side 17.2 merge into round channels 29. At least one or both channels 29 have a passage area, that is, flowed through cross-sectional area, that less than a 1/3 of the passage area of the Pressure areas 23 of the delivery-side pressure plate 17.1.
- the vane pump according to Figure 3a has both on the outlet or delivery side F of the rotor as also on the opposite pressure chamber side D a pressure plate 17.1 or 17.2. Both pressure plates 17 lie close to the contour ring and rotor 51 and are said to have a leakage of Prevent hydraulic oil from the pressure areas.
- the representation of the delivery-side pressure plate 17.1 in Figure 3a leaves two outlet channels 53.1 and 53.2 recognize each having a fluid connection between a pressure area and a conveyor respectively Create outlet area 55.
- the pressure chamber side is on the opposite side Pressure plate 17.2 on the rotor 51.
- she also has a channel 59, which is a fluid connection between a pressure range lower in the figure UD and a pressure chamber 61 produces.
- This pressure chamber 61 is on the one hand by the pressure plate side pressure plate 17.2 and on the other hand formed by the housing.
- the embodiment shown in Figure 3b differs different from the one just described in that the opening into the lower wing area Opening 63 not in the pressure plate on the pressure chamber side 17.2 but in the delivery pressure plate 17.1 is provided.
- the Channel 59 of the pressure plate 17.2 not the lower one Print area but assigned to the upper print area. A change in the way the two work This results in pressure plates after the start-up phase However not.
- FIG. 3c A third embodiment can be seen in FIG. 3c, which essentially corresponds to that in FIG 3a embodiment corresponds.
- the pressure plate side pressure plate 17.2 a small, in essential ventilation channel 65 is provided, the connection between the Pressure chamber 61 and the upper pressure area creates.
- the cross section of the channel 65 is dimensioned so that that its hydraulic resistance in particular for cold hydraulic oil with high viscosity is very large. Resistance should be on everyone Case be so large that in the cold start phase Oil flow from the lower pressure range over the pressure chamber 61 and the channel 65 in the upper pressure range, where the short circuit prevails, and then into the suction area is almost prevented.
- this ventilation channel 65 exists in accumulating in the upper area of the pressure chamber 61 To let air escape. Therefore this is Vent channel 65 the overhead pressure area assigned. Through the ventilation achieved with it the pressure chamber 61 can reduce noise achieve.
- Figure 3d shows a further embodiment, in which the pressure plate side pressure plate 17.2 two Has channels 71.
- the upper channel 71.1 connects the upper pressure area with the pressure chamber 61, the lower channel 71.2 the lower pressure range with the Pressure chamber 61.
- the cross sections of the two channels 71 are chosen so that the sum of the two individual hydraulic resistors for a viscous, cold oil is so big that almost no oil flow between the two pressure ranges developed by the pressure chamber 61.
- this pump is related to the venting function regardless of location, since each is in the upper Area of the pressure chamber regardless of the installation position there is a ventilation duct through which the accumulating air can escape.
- FIGS. 3e and 3f show two further exemplary embodiments shown how a pressure room side hydraulic resistance can be realized, for example instead of according to the small cross sections Figure 3d, can be used. So you can on the one hand provide a web 77 on the housing, which Oil flow in the cold start phase between lower and limited upper pressure range. In addition to the arrangement of the web 77 on the housing is of course also can be formed on the pressure plate 17.2, as in FIG. 3f shown. Other configurations are of course also possible hydraulic resistance is conceivable.
