(23), wherein, when in the first relative position the projection (22) of the first ring structure (20) rest on the prominent of the second ring structure (21)
When rising on (23), the most described ring structure has ratio and the projection (22) of the first ring structure (20) ought be applied in the second relative position
Construct in the reverse projection (29) between the projection (23) of the second ring structure (21) and the projection (23) of the second ring structure (21)
Bigger axial dimension when being applied in the structure reverse projection (28) between the projection (22) of the first ring structure (28).
6. according to the fluid machine described in claim 5, it is characterised in that all of stair-stepping of the first ring structure (20) dashes forward
Play (22) and be respectively provided with identical height in the axial direction, and all of stair-stepping projection of same second ring structure (21)
(23) it is respectively provided with identical height in the axial direction, thus ring structure (20,21) is two phase para-positions each other being defined
Put and can be connected with each other in the case of two different axial dimensions are provided.
7. according to the fluid machine described in claim 5, it is characterised in that at least one ring structure (20,21) stair-stepping
Projection (22,23) has the height that at least two is the most different, thus ring structure (20,21) is defined plural
The relative position of each other in providing in the case of plural different axial dimension and can be connected with each other.
8. according to the fluid machine according to any one of claim 5 to 7, it is characterised in that the hole of the first ring structure (20)
(26) quantity in the corresponding hole (27) in the second ring structure (21) of quantity is multiplied by tying at ring of the different axial dimension of offer
The quantity of the relative position between structure (20,21).
9. according to the fluid machine according to any one of aforementioned claim 1 to 4, it is characterised in that the first ring structure towards
There is on the face of the second ring structure the projection of the ramped shaped being spaced in the circumferential, and, the second ring structure is towards first
There is the projection of the ramped shaped being spaced in the circumferential, wherein, when the projection of the first ring structure rests on the face of ring structure
During the prominence of the second ring structure, then the relative position through the definition between described ring structure can infinitely set axially
Size and and then axial gap between minimum dimension and full-size.
10. according to the fluid machine described in claim 9, it is characterised in that the hole of one of ring structure is configured to screwed hole, and
The hole of another ring structure is configured to the elongated hole of the bending extended in the circumferential.
