Definitions
- the invention relates to a ⁇ lford- and vacuum pump with a
- Pump housing a rotor rotatably mounted in the pump housing, a rotor slidably mounted in the rotor whose vane tips abut the inner peripheral wall of a pump chamber and divide it into a suction chamber and a pressure chamber, wherein the wing extends transversely to the axis of rotation of the rotor, and with a in the Saugraum opening inlet and a discharge from the pressure chamber outlet.
- vacuum pumps are known in which a rotor in a pump housing is arranged eccentrically, with which a wing is rotated in a pump chamber.
- the wing touches with its wing tips, the inner peripheral surface or inner peripheral wall of the pump chamber and is thereby displaced oscillatingly in the rotor.
- Such vane pumps have the significant advantage that they are simple and have a low weight.
- the suction chamber formed in the pump chamber has an inlet which is arranged axially and the pressure chamber formed in the pump chamber has an outlet which lies in the inner peripheral wall of the pump chamber and has a check valve.
- the invention is based on the object, a ⁇ l desk- and
- the pump on the one hand has a small space, on the other hand has a high oil flow volume, is simple and also has a low power loss.
- Vacuum pump of the type mentioned above wherein the inlet and the outlet are arranged in the inner peripheral wall of the pump chamber.
- Vacuum pump are the inlet and the outlet in the radial direction, which has the significant advantage that the oil undergoes only small deflections, ie not from an axial direction of flow into a radial Direction or circumferential direction must be deflected, but flows radially into the pump chamber and flows out of this again radially.
- this aspect plays a minor role, since gases have a relatively low mass.
- this aspect is no longer negligible, but plays a crucial role, since axially inflowing liquids must be accelerated by the wing, which requires additional energy.
- the wing has a constant length.
- the wing can of course be provided in the form of a truss structure with extending in the longitudinal direction of the wing and / or parallel to the axis of rotation channels or depressions. As a result, weight is saved, whereby the inertial forces can be reduced and the wing can be accelerated and decelerated with less effort. In this way, the wear of the wing tips is reduced.
- the inlet and the outlet are in the same cross-sectional plane.
- Another alternative embodiment provides that the inlet and the outlet are arranged axially offset from one another.
- the inlet and the outlet in the radial direction extending wall surfaces. This means that the inlet and the outlet expand radially outward within the wall of the pump housing. In this way flow losses are reduced.
- Pump housing has two pump chambers and each pump chamber is closed with a housing cover.
- each pump chamber is closed with a housing cover.
- a rotor arranged with a wing, whereby the suction or volume capacity of the oil supply pump increases, in particular doubles, is.
- Oil-gas mixture and in the other pump room promoted a gas, in particular extracted.
- the rotor of two, in particular axially successively arranged rotor sections is formed, each rotor section is inserted into one of the two pump chambers.
- This embodiment has the advantage that only a single drive is required, and driven with this drive both rotor sections.
- Such ⁇ l boss- and vacuum pump is easy to control and has a high flow rate.
- the pump chambers may have the same or different volumes.
- a rotor portion is provided with a peg-shaped axial end and the other rotor portion with an axial sleeve-shaped end, wherein the one end of the spigot is inserted into the other end of the sleeve.
- a simple storage is created by the fact that the sleeve end of a rotor section in the pump housing, in particular in the partition wall between the two pump chambers, is mounted.
- the sleeve end of a rotor section forms the bearing for the journal end of the other rotor section. Lubrication of these bearings is advantageously carried out via the at least one of the two pump chambers promoted lubricating oil.
- a simple rotational coupling of the two rotor sections is carried out according to the invention in that the two ends of the rotor sections are connected to each other via a splined profile, a tongue and groove connection or a polygonal profile. This ensures that the two rotor sections are coupled together in the direction of rotation, in axial Direction but can be moved against each other. As a result, manufacturing-related game, temperature-induced changes in length of the rotor and the pump housing and the like can be compensated.
- the two pump housings can be connected in series or in parallel.
- the pump can be adapted to the required conditions with regard to the delivery volume and the suction pressure.
- a serial circuit of the subsequent pump chamber is larger than the previous pump room.
- the two pump chambers are arranged axially behind one another in the pump housing and are simultaneously penetrated axially by the rotor.
- This embodiment has the significant advantage that the pump has the above properties and that it is also quick and easy to install, which can be done in particular by machine.
- a housing wall in which at least one of the rotor sections is mounted.
- This housing wall forms the bottom for both pump chambers, each pump chamber is closed by its own, separate cover.
- the rotor sections are offset in the direction of rotation by 90 ° in the rotor chambers.
- the pumping noise of the oil feed and vacuum pump is considerably reduced and the pulsation of the oil feed and vacuum pump is minimized.
- the power consumption of the pump is much more uniform.
- Vacuum pump valve-free so that this also reduces power losses.
- Figure 1 is a side view of the invention ⁇ l boss- and vacuum pump, the inlets and the outlets shows;
- FIG. 2 shows a section M-II according to FIGS. 1, 3 and 4;
- FIG. 4 shows a section IV-IV according to FIG. 1.
- FIG. 1 shows an oil feed and vacuum pump, generally designated 10, as used, for example, for crankshaft extraction, cylinder head suction or turbocharger extraction of excess oil.
- the ⁇ l bulk- and vacuum pump 10 has a pump housing 12, which is designed substantially cylindrical and is closed at the two end faces with lids 14 and 16. From the cover 14 projects a stub axle 18, which can engage a (not shown) drive.
- the pump housing 12 in particular in its wall, there are two inlets 22 and two outlets 24 which, as can be seen from FIGS. 3 and 4, open into a suction space 26 or open out of a pressure space 28.
- an oil drain 30 can be seen, on which excess lubricating oil from the bearing 32 ( Figure 2) is removed.
- FIG. 2 shows a longitudinal section N-II according to Figures 1, 3 and 4 and it is clearly the pump housing 12 can be seen, which has a substantially H-shaped in cross-section.
- a rotor designated generally by 34 is used, which has two rotor sections 36 and 38.
- the rotor section 36 carries the axle stub 18 passing through the cover 14 and has on its opposite side a sleeve-shaped end 40 which is mounted in the bearing 32 of the pump housing 12 or a housing wall 42. In this sleeve end 40 engages a pin end 44, which is thereby mounted in the sleeve end 40.
- the spigot end 44 and the sleeve end 40 have a complementary splined profile, wherein the reference numeral 46, a tooth of the plurality profile is shown.
- the opposite side of the rotor portion 38 has a bearing pin 48 which is mounted in the housing cover 16.
- wings 50 and 52 are mounted such that they can be moved transversely to the axis of rotation 54. In this case, the wing tips 56 and 58 abut on the inner circumferential wall 60 of the two pump chambers 62 and 64.
- the wall surfaces 66 extend in the radial direction with respect to the axis of rotation 54.
- both the inlet 22 and the outlet 24 are designed valve-free. They open directly in the radial direction into the suction chamber 26 or from the pressure chamber 28.
- the inlet 22 and the outlet 24 of each pump chamber 62 and 64 are in the same cross-sectional plane IH-III or IV-IV.
- the inlets 22 and outlets 24 are in the same cross-sectional planes III - III and IV - IV.
