- the playeragregat invention with the characterizing features of claims 1 and 11 has the advantage that a deformation of the pump chamber by hydraulic forces or by Einpress theory is avoided by ribs are provided on the pump chamber remote from the outside of the peripheral wall and / or by a shoulder to Pressing the pump part is provided in the pump housing, which is formed so thin-walled that the pressing forces do not reach deformation of the end wall of the pump chamber.
- the ribs according to claim 1 also reduces the area over which noises are transmitted from the track to the housing of the delivery unit. In this way, the noise behavior of the delivery unit is improved.
- the ribs are advantageously arranged in the axial region of the pump chamber and increase in this way the strength of the peripheral wall.
- FIG. 1 shows in section a delivery unit according to the invention and FIG. 2 shows a view of the pump part according to the invention according to FIG.
- FIG 1 shows in section an inventive delivery unit.
- the delivery unit has a pump housing 1 with at least one input channel 2 and an output channel 3.
- the input channel 2 of the delivery unit is connected for example via a suction line 6 with a reservoir 7, in which, for example, fuel is stored.
- the output channel 3 of the unit is connected via a pressure line 8, for example with an internal combustion engine 9.
- the delivery unit is a roller-cell pump whose operation is known for example from DE 103 33 190 Al.
- the pump housing 1 has a pump chamber 12, in which a rotor 13 is mounted eccentrically and rotatably.
- the rotor 13 is driven in rotation by an actuator 14, for example an electric motor, via a drive shaft 15.
- the pump chamber 12 is limited by two in the direction of a rotor axis 16 opposite end walls 19,20 and in the radial direction with respect to the axis 16 of a than
- Track formed peripheral wall 18 The first end wall 19 is formed on the rotor 13 facing the inside of a lid 21 and the second end wall 20 on the rotor 13 facing the inside of a pump part 22.
- the peripheral wall 18 is integrally formed on an annular collar 25 of the pump part 22.
- the pump part 22 has at least one outlet 23 from the pump chamber 12.
- a coating or a ring 26 may be provided on the inner side facing the pump chamber 12, which forms the raceway 24 for the sealing body 29 arranged in the rotor 13.
- the peripheral wall 18 can expressly also form the track 24 itself.
- a plurality of grooves 23 are arranged distributed over the circumference of the rotor 13.
- the grooves 23 extend through the rotor 13 in the axial direction from one end face of the rotor 13 to the other end face.
- the grooves 23 extend in each case from the outer periphery radially inward with two, for example, mutually parallel side edges and terminate in an example arcuate groove bottom 28.
- a sealing body 29 is provided, which is for example designed as a cylindrical roller.
- the sealing body 29 is movably mounted between the groove base 28 and the raceway 24. The sealing body 29 are moved during the rotation of the rotor 13 in the direction of the raceway 24 and are usually on the track 24 at.
- the lid 21 and the pump part 22 are surrounded by a cylindrical housing wall 32.
- the two parts 21,22 are frontally inserted into the housing 1, wherein the housing wall 32 is crimped and beaded at its lid 21 facing the end portion to the parts 21, 22 to be stored firmly in the housing 1.
- FIG. 2 shows a side view of the pump part according to the invention according to FIG.
- the circumferential wall 18 or the collar 25 with the raceway 24 is arranged eccentrically with respect to the rotor axis 16.
- the housing 1 with the housing wall 32 is provided centrally with respect to the rotor axis 16.
- the peripheral wall 18 or the collar 25 has, for example, a constant wall thickness over its circumference. Furthermore, the wall thickness of the peripheral wall 18 and the collar 25 is made comparatively small, in order to avoid an accumulation of material and the formation of voids.
- the lid 21 and / or the pump part 22 are made for example of plastic by injection molding. - A -
- ribs 34 are formed on the outer side 33 of the circumferential wall 18 or of the collar 25 facing away from the pump chamber 12.
- the ribs 34 enhance the strength of the peripheral wall 18 and the collar 25, respectively, so that the pumping chamber 12 is not deformed by the hydraulic pressure load on the pumping chamber 12 or due to vibration, but maintains its predetermined shape.
- the ribs 34 are arranged in the axial region of the pump chamber 12, for example, between the first end wall 19 and the second end wall 20. However, they can expressly extend beyond the second end wall 20. For example, they extend from the end 21 of the cover 21 of the pump part 22 over a predetermined length in the axial direction. In the radial direction with respect to the rotor axis 16, the ribs 34 extend from the outside 33 of the circumferential wall 18 to a housing wall 32.
- the ribs 34 are distributed over the circumference of the peripheral wall 18 and the collar 25, for example, uniformly or non-uniformly and are spaced apart in the circumferential direction, so that recesses are formed between them.
- At least one shoulder 40 is provided on the side of the end wall 20 facing away from the pump chamber 12 or facing the actuator 14, said shoulder being provided with the cylindrical one by means of an interference fit
- Pump housing 1 is non-positively connected and which is formed so thin-walled that initiated via the shoulder 40 pressing forces do not reach deformation of the end wall 20 of the pump chamber 12.
- This inventive design prevents the end wall 20 of the pump chamber 12 is deformed during the pressing of the pump part 22 into the pump housing 1. This could cause an increased friction on the rotor 13 or this could be completely blocked.
- the wall thickness s of the at least one shoulder 40 is smaller by a multiple than the radius r of the pump housing 1, for example 5 to 10 times smaller.
- the interference fit is mainly in the region of the shoulder 40 and not in the region of the pump chamber 12, so that the housing wall 32 of the pump housing 1 outside the shoulder 40 at most low forces on the pump chamber 12 exerts, however, cause no deformation of the pump chamber 12.
- the at least one shoulder 40 is arranged, for example, radially outside the pump chamber 12.
- a single shoulder 40 is provided which forms a closed ring.
- the annular shoulder 40 may also be interrupted, so that a plurality of teilringf ⁇ rmige shoulders 40 are present.
- the at least one shoulder 40 has on the side facing the pump housing 1 side not shown longitudinal ribs, for example, have Füschrrägen.
- the embodiment with the at least one shoulder 40 may be provided as shown in Figure 1 in combination with the ribs 34 according to the invention. However, it is expressly also possible to carry out the at least one shoulder 40 according to the invention without the ribs 34 according to the invention being formed on the circumferential wall 18, 25.
