Universal adapter

Abstract

A universal adapter includes a main tube for a combined suction unit and blasting unit. The main tube has a first connecting section for connection to a suction line of the suction unit and a second connecting section for connection to a working chamber. In order to reduce the number of suction adapters needed to connect to different openings in working chambers, the second connecting section is made of a flexible material and has a cutout in its periphery that extends from a free end of the second connecting section in the direction of the longitudinal axis of the main pipe.

Claims

1. A universal adapter, comprising: a main tube for a combined suction unit and granulate blasting unit, said main tube having a longitudinal axial direction, a first connecting section to be connected to a suction line of the suction unit and a second connecting section being configured to be connected to a working chamber; said second connecting section being formed of a flexible material, said second connecting section having a free end and said second connecting section having a periphery with a cutout formed therein for changing a diameter of said free end of said second connecting section; and said cutout extending from said free end in said longitudinal axial direction.

2. The universal adapter according to claim 1, wherein said cutout is V-shaped.

3. The universal adapter according to claim 1, wherein said first connecting section is formed of a flexible material.

4. The universal adapter according to claim 1, wherein said first connecting section has a free end expanding conically.

5. The universal adapter according to claim 1, wherein said main tube is formed as a single part having said connecting sections formed of a flexible material.

6. The universal adapter according to claim 1, which further comprises a sealing collar disposed on said main tube, said sealing collar being adjustable between a sealing position projecting beyond said free end of said second connecting section and an installation position exposing at least said cutout.

7. The universal adapter according to claim 1, wherein said main tube has a periphery and a tube hole formed in said periphery of said main tube and oriented toward said second connecting section.

8. The universal adapter according to claim 7, wherein: said main tube has a longitudinal axis extending in said longitudinal axial direction; and said tube hole has a longitudinal axis enclosing an angle of 10 to 60 with said longitudinal axis of said main tube.

9. The universal adapter according to claim 7, wherein: said main tube has a longitudinal axis extending in said longitudinal axial direction; and said tube hole has a longitudinal axis enclosing an angle of 15 to 40 with said longitudinal axis of said main tube.

10. The universal adapter according to claim 7, wherein: said main tube has a longitudinal axis extending in said longitudinal axial direction; and said tube hole has a longitudinal axis enclosing an angle of 20 to 30 with said longitudinal axis of said main tube.

11. The universal adapter according to claim 7, wherein said main tube has a middle section disposed between said first and second connecting sections, and said tube hole is disposed in a region between said second connecting section and said middle section.

12. The universal adapter according to claim 7, wherein said main tube has a side opposite said cutout, and said tube hole is disposed on said side of said main tube opposite said cutout.

13. The universal adapter according to claim 1, wherein said cutout has opposing end faces approaching one another and reducing a diameter of said second connecting section in an installed condition of said second connecting section in an opening of a working chamber.

14. A universal adapter, comprising: a main tube for a combined suction unit and granulate blasting unit, said main tube having a longitudinal axial direction, a first connecting section to be connected to a suction line of the suction unit and a second connecting section to be connected to a working chamber; said second connecting section being formed of a flexible material, said second connecting section having a free end and said second connecting section having a periphery with a cutout formed therein; said cutout extending from said free end in said longitudinal axial direction; and a sealing collar disposed on said main tube, said sealing collar being adjustable between a sealing position projecting beyond said free end of said second connecting section and an installation position exposing at least said cutout.

Description

BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWING

(1) FIG. 1 is a diagrammatic, perspective view of a universal adapter;

(2) FIG. 2 is a top-plan view of the universal adapter of FIG. 1; and

(3) FIG. 3 is a bottom-plan view of the universal adapter of FIG. 1.

DETAILED DESCRIPTION OF THE INVENTION

(4) Referring now in detail to FIGS. 1 to 3 of the drawings as a whole, there is seen an embodiment of a universal adapter 1. The universal adapter 1 has a main tube 2 produced from a textile-reinforced plastic that has a V-shaped cutout 5 in its second connecting section 4 to be disposed in various openings of working chambers (not shown in this case) of, for example, different cylinder heads. The cutout 5, which penetrates the tube casing, extends toward a first connecting section 3 in the direction of a longitudinal axis of the main tube 2 starting from an end face 8 of the second connecting section 4 and makes it possible to compress or upset the second connecting section 4 in the region of the cutout 5 so that the diameter changes due to opposing end faces of the cutout 5 approaching one another. The second connecting section 4 can accordingly be disposed in openings of working chambers with different diameters.

(5) A sealing collar 6 is disposed coaxially to the main tube 2 and is shown in its installed position in FIG. 1 to FIG. 3. In the installed position, the accessibility to the second connecting section 4 allows it to be easily disposed in an opening of the working chamber. After placement of the second connecting section 4, the sealing collar 6 is then moved toward the free end of the second connecting section 4 until its sealing surface running parallel to the end face 8 lies against the surface in the region around the opening in which the second connecting section 4 is disposed.

(6) A tube hole 7 penetrating the tube casing and being disposed on the side opposite the cutout 5 runs toward the second connecting section 4 in a middle region of the main tube 2. The tube hole 7 makes it possible to provide a blasting tube (not shown herein) through the use of which an abrasive is introduced into the working chamber.

(7) The following is a summary list of reference numerals and the corresponding structure used in the above description of the invention: 1 Universal adapter 2 Main tube 3 First connecting section 4 Second connecting section 5 Cutout 6 Sealing collar 7 Tube hole 8 Face
