Definitions
- the invention relates to a positive displacement pump with the Features of the preamble of claim 1.
- a positive displacement pump is already known from DE 41 07 720 A1, whose the two chambers of the pump housing space separating, guided wing on both Front ends each movable in the longitudinal direction of the wing guided and on the inner peripheral wall of the housing space wearing sealing strip.
- these are in Cross-section T-shaped, the T-beam is convexly curved on the outside in cross section and accordingly the peripheral wall only along a surface line touched.
- the middle ledge is on the front with one in the wing molded longitudinal groove movable in the longitudinal direction of the wing engaged so that the sealing strips when the drive shaft rotates under the action of centrifugal force automatically attach to the inner wall of the housing.
- Positive displacement pumps of this embodiment are therefore suitable e.g. not for the evacuation of a brake booster a motor vehicle, since in this case even small ones Speeds an evacuation must be ensured.
- the invention is therefore based on the object Provide positive displacement pump, which also without problems Motor vehicles can be used.
- the optimal material pairings become.
- the components that are heavily used are made of a harder material, e.g. Metal and / or ceramic manufactured, the components being kinematically strong be claimed, i.e. which often accelerates and decelerates are made of a lighter material.
- connection is a metal-plastic connection, Metal-ceramic connection, metal-plastic-ceramic connection or plastic-ceramic connection.
- the plastic can be a polyether ether ketone (PEEK), Polyether sulfide (PES), syndiotactic polystyrene (SPS) or a polyphenylene sulfide (PPS).
- PEEK polyether ether ketone
- PES Polyether sulfide
- SPS syndiotactic polystyrene
- PPS polyphenylene sulfide
- the positive displacement pump according to FIG. 1 comprises in a known manner Way a pump housing 10, one in its e.g. circular cylindrical housing space 12 eccentrically mounted Pump rotor 16, the drive shaft 14 rotatably is connected in a rotationally fixed manner and radially in this slidably guided rotor blade 18, which at its Wing ends each carries a sealing strip 20 or 22.
- the pump rotor 16 preferably has a hollow cylindrical one Rotor shell 24 in which one along its Inner diameter extending inner wing guide strip 26 is provided, in which the rotor blade 18 is radial is slidably received. 28 denotes inner rotor webs for stiffening the rotor shell.
- the rotor 16 is for Drive shaft 14 as a guide for the wing 18th slotted and plugged onto the shaft 14, inserted or molded.
- the housing space 12 is, for simplicity's sake, not is shown, tightly closed on both ends, the drive shaft 14 the one housing end wall penetrated liquid-tight.
- At the housing space 12 are also an inflow and an outflow line connected to a fluid to be promoted To be able to supply and discharge positive displacement pump.
- the sealing strips 20, 22 of the rotor blade 18 are in the Cross section preferably U-shaped and overlap one with their U-legs 30, 32 the wing tips preferably over the entire Wing width molded guide bar 34.
- the sealing strips 20, 22 for In the longitudinal direction of the rotor blade 18 these are preferred with two spaced apart and parallel to each other provided guide pieces 36, 38 equipped to integrally formed the connecting web 40 of their U-legs 30, 32 are and extend parallel to these, their Length is preferably less than that of the U-leg 30, 32.
- the guide pieces 36, 38 each engage in one blind hole-like recess 42 and 44 and so also an exact alignment of the sealing strips 20, 22 transversely to the longitudinal direction of the wing.
- the U-leg connecting web 40 of the sealing strips 20, 22 is preferably designed in cross section so that it on the outside at the same time a sealing edge 46 is defined.
- an energy store preferably in the form a leaf spring 48 is provided, which constantly tries to relevant sealing strip 20 or 22 in the direction of To shift or circumferential inner wall of the housing space 12 to keep in touch with this.
- a compression spring 50 or 52 can be introduced, on which the ledge guide pieces 36, 38 are supported (FIG. 3).
- the rotor blades 18 and the sealing strips 20, 22 are preferably designed as a molded plastic part, the Rotor blades 18 in particular for the purpose of uniform material distribution in the spraying process, for example with three of these in Transverse direction parallel to its flat sides, Flat slot-like recesses 54 is equipped.
- the Pump rotor 16 can also be stored centrally in the housing space 12 if the latter has an oval peripheral shape.
- the positive displacement pump according to FIGS. 5 and 6 comprises one Flange body with a pump housing 61 forming Cylinder cup 62, a pump drive shaft mounted in this 63 with attached rotor 64 and one in one the recess running rotor center, as Whole with 65 marked, two-part wings.
- the sealing strips 66 face the wall of the cylinder pot 62 provided with a concave radius 68 (Fig. 5). Consequently there are two lines of contact at 69 and 70, which in Interaction with the flat wing sections 65 ', 65' ' to seal the chambers in front of and behind the wing 65 serve. Radii 71 are at the ends of the sealing strips 66 and 72 are provided, which ensures optimal resealing is achieved.
- the rotor 64 is towards the drive shaft 63 as a guide for slotted the wing 65 and plugged onto the shaft 63, inserted or molded.
- This change in length is due to the radial mobility of the Wing sections 65 ', 65' 'balanced.
- the adaptation to the variable length in the angle of rotation happens through that Pressing the sealing strips 66 and taking the Wing 65 through the drive shaft 63 through the shaped spring 67 or by a corresponding compression spring, which the Wing sections 65 ', 65' 'apart and with this connected sealing strips 66 to the Pressed on cylinder wall.
