Definitions
- the invention relates to an oil-sealed rotary vane vacuum pump with an oil pump, the pumping chamber is equipped with supply lines for oil and gas.
- the oil with gas preferably air a reduction in the operating noise of the vacuum pump reached.
- a rotary vane vacuum pump with the features of the generic term of claim 1 is from DE-A-3922417 known.
- the gas and oil feeds into the pumping chamber the oil pump according to the prior art are such arranged that the oil pump first only air and then only sucks oil. This is achieved in that the Distance between the air intake openings on the one hand and oil, on the other hand, is so large that the intake opening is only released for oil when the next slider already the circulating funding volume separated from the air intake.
- a simultaneous intake of air and oil is not possible.
- the previously known solution therefore uses an oil pump with at least three evenly over sliders ahead of the circumference. Only because of that ensures that oil is also in the start-up phase of the pump is sucked in.
- the present invention is based on the object an oil-sealed vacuum pump of the type mentioned to be designed such that their supply with a gas-oil mixture is particularly simple.
- the pump 1 shown comprises the assemblies housing 2, rotor 3 and drive motor 4.
- the housing 2 has essentially the shape of a pot with an outer wall 5, with the lid 6, with a Inner part 7 with the scoops 8, 9 and the bearing bore 11, with the end plate 12 and the bearing piece 13, which close the scoops 8, 9 at the end.
- the Axis of the bearing bore 11 is designated 14.
- Between outer wall 5 and inner part 7 is located the oil space 17, which partially during the operation of the pump is filled with oil.
- oil eyes 18, 19 in the cover 6 maximum, minimum Oil level. Oil filler and drain plug are not shown.
- the oil sump is designated by 20.
- the rotor 3 is located within the inner part 7 is formed in one piece and has two end faces Anchor sections 21, 22 and one between the Anchor sections 21, 22 located bearing section 23 on.
- the anchor sections 21, 22 are provided with slots 24, 25 equipped for two sliders 26, 27.
- the representation according to Figure 1 is chosen so that the respective slide spaces 28, 29 lie in the plane of the drawing.
- the slide slots 25, 26 are each of the associated Milled end face of the rotor, so that in exact slot dimensions can be achieved in a simple manner can.
- the bearing section 23 lies between the anchor sections 21, 22. Bearing section 23 and bearing bore 11 form the only bearing of the rotor.
- Anchor section 22 and the associated scooping space 9 have a larger diameter than the anchor section 21 with the scooping space 8.
- Anchor section 22 and scooping space 9 form the high vacuum stage.
- the inlet of the high vacuum stage 9, 22 with the intake manifold 30 in connection stands the inlet of the high vacuum stage 9, 22 with the intake manifold 30 in connection.
- the outlet of the high vacuum stage 9, 22 and the inlet of the fore-vacuum stage 8, 21 via the housing bore 31 in connection extends parallel to the axes of the scoops 8, 9.
- the outlet of the forevacuum stage 8, 21 opens into the oil space 17. There the oily gases calm down and leave the pump 1 through the outlet port 33.
- the inlet and outlet openings are clear of the two pump stages not shown in Fig. 1.
- the housing 2 of the pump is expedient from as few as possible Parts built up. At least that the two scoops 8, 9 and wall sections comprising the oil chamber 17 5, 7 should be formed in one piece.
- the bearing piece is coaxial with the axis 14 of the bearing bore 11 13 with a bore 35 for a rotor drive equipped. This can be the shaft 35 of the Drive motor 4 be.
- the embodiment is between the free end face the drive shaft 36 and the rotor 3 a coupling piece 37 provided. The way of coupling the coupling piece 37 with the drive shaft 36 on the one hand and with the rotor on the other hand is not described in detail. It is explained in more detail in DE-A-43 25 285.
- the pump shown is equipped with an oil pump. This consists of the in the bearing piece 13 of the Scooping space 45 embedded in the engine side with the therein rotating oval eccentric 46.
- the eccentric is a Locking slide 47 on, under the pressure of the coil spring 48 stands.
- the eccentric 46 of the oil pump is a component of the coupling piece 37. It is either fixed or positive - only with axial play - with the coupling piece 37 connected.
- the oil pump 45, 46 is 64 via a first channel from the oil space 17 and a second channel 65 oil from the Oil sump 20 supplied.
- the air-oil mixture leaving the oil pump enters channel 66 which enters the bearing bore 11 (mouth 67) opens.
- mouth 67 is the bearing pin 23 with a continuous radial bore 68 provided, of which an axial bore 69 with a nozzle 70 branches in the direction of the slide gap 28.
- the location of the mouth 67 of the channel 66 on the one hand and the mouth of the radial bore 68 in the journal 23 on the other hand is chosen so that oil from channel 66 only can then briefly enter the bore 68 when the slider 26 take their T position.
- the vacuum pump according to the invention is a one-stage Pump, then the relevant portion of the oil-air mixture flows over the bores 66, 68, 69 and the slide gap 28 into the scooping chamber 8 and arrives from there back into the oil space 17. Just a very small one Part of the oil gets into the bearing gap between the bearing bore 11 and journal 23 and supplies this storage with lubricating oil. It flows through the bearing gap and then also reaches the scooping chamber 8. Is the vacuum pump - As in the embodiment of Figure 1 shown - trained in two stages, a third occurs Oil-air partial flow in the bearing gap of the bearing 11, 23 in the direction of high vacuum pump stage 9, 22. Would Oil-air mixture get into the high vacuum stage, then would the air contained in the oil the final pressure behavior of the vacuum pump.
- the bearing pin 23 has a circumferential groove 74 equipped, at the height of which a bore 75 opens communicates with the intermediate vacuum (bore 31).
- Figure 2 shows a plan view of the bearing piece 13.
- the circular scoop 45 of the Oil pump let in there is a in the scoop oval-shaped rotor 46, the locking slide 47 of lies below.
- the direction of rotation is indicated by an arrow featured.
- an oil supply 81 In the volume that increases its volume (right of the gate valve 47) opens first an oil supply 81.
- Via a laterally branching groove 82 it stands with the back of the locking slide 47 in Connection, supplies it with lubricating oil and causes a pressure relief in the gate valve slot.
- An air supply 83 opens out offset by the angle ⁇ the scooping space 45. This is also designed as a groove and stands with the air supply duct 64 ( Figure 1) in Connection.
- the oil-air mixture drawn in depends on the respective delivery volume promoted to outlet 84. This is formed from a groove that communicates with channel 66 ( Figure 1) stands.
- the size of the angle ⁇ (azinuthal distance of the Air supply from the oil supply) depends on the proportion of Air in the oil-air mixture. By changing the angle ⁇ can be influenced on this part.
- the size of the angle ⁇ is between 5 ° and 90 °, preferably 30-40. It is essential that - this also applies for rotors designed differently than shown - while a significant part of the intake bunny both oil and air is also sucked in.
