Abstract
Hose coupling component, especially for a hose connection between a turbo charger and an air cooler in an internal combustion engine, comprises a pipe sleeve (12) of pressed sheet metal, which has a peripheral flange (16) to be fixed by means of a V-shaped clamp to a corresponding mirror image flange on a complementary coupling component. The sleeve has a groove (18) for a gasket in the flange and has a circumferential depression (15) for indexing a hose (1) forced onto the coupling component.

Method of manufacturing a hose coupling component, comprising a pipe sleeve, which is provided at a first end with a peripheral flange projecting from a lateral surface of the sleeve, said flange having a side facing towards a second end of the pipe sleeve and inclined towards said first end, said flange forming an outer limitation of a circumferential groove which is open towards said first end for a gasket ring, said pipe sleeve also having between its ends a portion with a circumferential profile, wherein
- a bowl is pressed from a sheet metal element,
- the upper edge portion of the bowl is folded, so that said flange and the circumferential groove are formed,
- the bottom of the bowl is cut away, and
- a portion between the flange and an opposite end of the sheet metal element is press rolled so that a profile in the form of a depression is formed in the lateral surface of the pipe sleeve.
Hose coupling component, comprising a pipe sleeve, which is provided at a first end with a circumferential flange extending from a lateral surface of the sleeve, and having a side facing a second end and inclined towards the first end, said flange forming the outer limitation of a circumferential groove open towards the first end, for a gasket ring, said pipe sleeve having between its ends a portion with a peripheral profile,
- the pipe sleeve comprises a pressed sheet metal element, which has at a first end a folded edge portion, forming said flange and said circumferential groove, said pipe sleeve having a profile portion in the form of a depression in a lateral surface of the pipe sleeve between the flange and its opposite end.
A hose coupling component, comprising:
- a pipe sleeve having a first end and a second end;
- a circumferential flange arranged on said pipe sleeve at the first end thereof;
- said flange having a side facing toward said second end, wherein said side is inclined toward said first end;
- a first circumferential groove arranged in said flange, said groove being open towards said first end of the pipe sleeve;
- a second circumferential groove arranged around said pipe sleeve at a location between said flange and said second end.
