Adhesion is constituted), it is possible to balance connects between the stator core 2 and rotor (not shown) of eccentric worm pumps along spiral helicine
The prestressing force that tactile line lacks.
Fig. 4 A to Fig. 4 E show by formpiston 11 manufacture can hydraulic pressure adjustment stator 5 distinct methods step.The formpiston
11 (specifically referring to Fig. 4 B and Fig. 4 C) have copied helical orbit 12-1,12-2 of intermediate cavity 6, and (it is relative in the stator 5 for making
And put), especially region 8, does not form between stator core 2 and stator outer housing 3 in the stator 5 for making glue in the region
Attached (with reference to Fig. 2).
The formpiston 11 has formed in substantially rectangular basic configuration, and it has longitudinal axis L 11GF of centre.The energy of formpiston 11
It is enough to be rolled up together in the form of cylinder around the second longitudinal axis L 11, therefore longitudinal axis L 11GF of centre and the second longitudinal axis
L11 is abreast oriented.The longitudinal axis of the template cylinder 11Z therefore equivalent to volume together of the second longitudinal axis L 11.
The side (it is parallel with central longitudinal axis L11GF of formpiston 11) of formpiston 11 is direct in rolled-up formpiston 11Z
It is adjacent, and while parallel to the second longitudinal axis L 11 and parallel to middle longitudinal axis L 11GF.So rolled-up formpiston
11Z define especially at least one, preferably two helical orbit 12-1,12-2, therefore they are subsequently in the (ginseng of stator 5 for making
According to Fig. 3) middle composition.
The rolled-up formpiston 11Z is so arranged on the inside of stator outer housing, second longitudinal axis or rolled-up mould

Uncoated adhesive in the region 31 that the formpiston 11Z for coming is covered.Elastomer can be inserted in stator outer housing 3 now, stator iron
Core 2 can be constituted in conventionally known mode, wherein be particularly, so-called rotor core is in order to form (the reference of rotor receiving portion 4
In Fig. 1) pushing the elastomer of stator core 2.Here passes through elastomer and metal stator outer cover of the adhesive in stator core 2
Firm connection is produced between 3.
After the elastomer is hardened, it is sticked in the interior mask surface of stator outer housing 3, and be such region it
Outward, i.e., it is applied in the interior mask surface of stator core 2 without adhesive in this region.Rotor core is removed.Wait behind
Inner space defines so-called bore of stator or rotor receiving portion 4 (with reference to Fig. 2), and the rotor of eccentric worm pumps is subsequently located at
In the rotor receiving portion, and the conveying moved in the conveying direction is internally formed in rotor receiving portion 4 by rotary motion
Chamber.
Especially in Fig. 4 B as shown in Fig. 4 C, formpiston 11 is so constituted, i.e., the region for being covered by formpiston 11
12 by the way that formpiston 11 is correctly rolled in the form of template cylinder 11Z, around the longitudinal axis of rolled-up template cylinder 11Z
Line L11 forms two helical orbits 12-1,12-2.The longitudinal axis of formpiston 11Z that is rolled-up and being arranged in stator outer housing 3
L11 especially overlaps with the longitudinal axis L 3 of stator outer housing 3 or the longitudinal axis L 5 of stator 5.
In addition it can also be seen that two helical orbits 12 of rolled-up formpiston 11Z are from side especially in Fig. 4 B and Fig. 4 C
