Abstract

The invention concerns a refrigerant compressor arrangement with a compressor having a suction inlet, a casing, in which the compressor is located, a suction socket, which is in communication with the casing, a suction opening in the casing, which is connected with the suction socket, and a telescopic pipe, which is located between the suction inlet and the suction opening in the casing. It is endeavored to manufacture a refrigerant compressor arrangement in a cost-effective manner. For this purpose, the suction opening is surrounded by a drawing through in the casing wall, whose inner wall forms a sliding surface for the telescopic pipe.

Claims (26)

1. A refrigerant compressor arrangement with a compressor comprising: a suction inlet, a casing, in which the compressor is located, a suction socket, which is connected with the casing, a suction opening in the casing, which is in communication with the suction socket, and a telescopic pipe, which is located between the suction inlet and the suction opening in the casing, wherein the suction opening is surrounded by a drawing through formed in the casing wall, and extending outwardly therefrom, whose inner wall surface remains in sliding contact with the telescopic pipe, the surface allowing pivotal movement of the telescopic pipe.

2. The arrangement according to claim 1 , wherein the telescopic pipe projects through the drawing through and has a protrusion arrangement on a section projecting from the drawing through, said protrusion arrangement forming, together with the outer frontside of the drawing through, a movement limitation device.

3. The arrangement according to claim 1 , wherein the suction opening has an increasing diameter at both ends thereof.

4. The arrangement according to claim 1 , wherein the drawing through is directed outwards from the casing.

5. The arrangement according to claim 1 , wherein the suction socket surrounds the drawing through with a fixing section.

6. The arrangement according to claim 5 , wherein the fixing section surrounds the drawing through with a distance to all sides.

7. The arrangement according to claim 2 , wherein an annular chamber is formed between the suction socket and the section of the telescopic pipe projecting from the drawing through.

8. The arrangement according to claim 1 , wherein the suction opening is surrounded by a plane surface.

9. The arrangement according to claim 1 , wherein the drawing through is surrounded by a plane surface.

10. The arrangement according to claim 9 , wherein the suction socket is supported on the plane surface.

11. The arrangement according to claim 5 , wherein at the end facing away from the casing, the suction socket has a cylinder section, which includes a closed end section, the cylinder section having a predetermined break point.

12. The arrangement according to claim 11 , wherein the fixing section and the cylinder section are connected by means of a corrugated pipe-like section.

13. The arrangement according to claim 12 , wherein in the area of the corrugated pipe-like section, the cylinder section has an inner diameter reduction.

14. The arrangement according to claim 1 , wherein the suction socket has a smaller wall thickness than the casing.

15. The arrangement according to claim 1 , wherein the telescopic pipe has a bearing surface on the compressor, which is, at least in sections, made to be spherical.

16. The arrangement according to claim 1 , wherein the compressor has a supporting surface surrounding the suction inlet, said supporting surface having, at least in sections, a spherical shape.

17. The arrangement according to claim 16 , wherein the suction inlet is formed on a suction muffler located on the compressor, the outer wall of said suction muffler being made of a plastic material.

18. The refrigerant compressor arrangement according to claim 1 , wherein the drawing through is formed integrally with the casing wall.

19. The refrigerant compressor arrangement according to claim 1 , wherein the sliding surface of the drawing through allows tilting movement of the telescoping pipe therein.

20. A refrigerant compressor arrangement with a compressor comprising:

a suction inlet;

a casing, in which the compressor is located;

a suction socket, which is connected with the casing;

a suction opening in the casing, which is in communication with the suction socket; and

a telescopic pipe, which is located between the suction inlet and the suction opening in the casing;

wherein the suction opening is surrounded by a drawing through formed in the casing wall, and extending outwardly therefrom, whose inner wall surface remains in sliding contact with the telescopic pipe, the surface allowing pivotal movement of the telescopic pipe; and wherein the drawing through is formed such that the suction opening has an increasing diameter at both ends thereof.
