Abstract

A collector, in particular a refrigerant collector for a refrigerant circuit, in particular of a motor vehicle, which is formed with a tubular housing body with a circumferential wall and with a first end face and with a second end face, wherein the housing body at the first end face has a closable first opening, into which a sealing plug can be inserted for closing the first opening, wherein the sealing plug has a circumferential groove into which a sealing element can be inserted for sealing between the sealing plug and the circumferential wall, wherein the circumferential groove has a groove bottom, which slopes in the axial direction. A sealing plug is also provided.

Claims (17)

1 . A collector, the collector being a refrigerant collector for a refrigerant circuit of a motor vehicle, the collector comprising:

a tubular housing body with a circumferential wall and with a first end face and with a second end face;

a closable first opening arranged on the housing body at the first end face; and

a sealing plug that is inserted into the first opening for closing the first opening,

wherein the sealing plug has a circumferential groove into which a sealing element is adapted to be inserted for sealing between the sealing plug and the circumferential wall, the circumferential groove having a groove bottom that slopes in an axial direction,

wherein the groove is defined by a first side wall and a second side wall arranged spaced apart therefrom and by the groove bottom between the first and second side walls, wherein the first side wall adjoins a deeper end of the groove bottom and the second side wall adjoins a less deep end of the groove bottom,

wherein an inwardly facing side of the first end face of the housing body has an annular region, the annular region being a surface that slopes in the axial direction, and

wherein, in a fully inserted state of the sealing plug in the first opening of the housing body, an upper edge of the surface of the housing body that slopes in the axial direction contacts the first side wall of the groove at a point that is between a radially inner edge of the first side wall and a radially outer edge of the first side wall, and wherein the first side wall continuously faces a same direction perpendicular to the first side wall, from the radially inner edge to the radially outer edge.

2 . The collector according to claim 1 , wherein the first side wall extends radially further inward than the second side wall.

3 . The collector according to claim 1 , wherein the first side wall extends radially further outward than the second side wall so that the first side wall overlaps the second side wall radially outward.

4 . The collector according to claim 1 , wherein the groove bottom slopes axially outward from the first side wall to the second side wall.

5 . The collector according to claim 1 , wherein the annular region that slopes in the axial direction slopes outward axially in a direction from the second side wall of the groove towards the first side wall.

6 . The collector according to claim 1 , wherein a region enclosed by the annular region of the first end face of the housing body, the groove bottom and the first and second side walls of the groove is trapezoidal or triangular in cross section and receives the sealing element.

7 . The collector according to claim 1 , wherein the sealing element is an O-ring.

8 . The sealing plug for the collector according to claim 1 , wherein the sealing plug has a base body, wherein the sealing plug has the circumferential groove into which the sealing element is adapted to be inserted for sealing between the sealing plug and the circumferential wall of the collector, and wherein the circumferential groove has the groove bottom, which slopes in the axial direction.

9 . The collector according to claim 1 , wherein, in the fully inserted state of the sealing plug in the first opening of the housing body, a lower edge of the surface of the housing body that slopes in the axial direction contacts a radially outer edge of the second side wall of the groove.

10 . The collector according to claim 1 , wherein the sealing element contacts the groove bottom of the sealing plug when the sealing element is inserted in the groove.
