Abstract
An overrun air recirculation valve 1 of an exhaust-gas turbocharger compressor 2, having a valve housing 3 which has an interior 4, having a diaphragm 5 which is guided in the interior 4 and which has an edge-side sealing means 6; and having a connecting means 7 provided on the valve housing 3, wherein the sealing means 6 is in the form of a sealing means which acts in the radial direction R of the diaphragm 5.
Claims12
An overrun air recirculation valve (1) of an exhaust-gas turbocharger compressor (2), having
- a valve housing (3) which has an interior (4),
- a diaphragm (5)
- which is guided in the interior (4) and
- which has an edge-side sealing means (6);
- and
- a connecting means (7) provided on the valve housing (3),
- wherein the sealing means (6) is in the form of a sealing means which acts in the radial direction (R) of the diaphragm (5).
A method for the mounting of an overrun air recirculation valve (1) on a compressor housing (14) of a compressor (2) of an exhaust-gas turbocharger (13), having the following method steps:
- preassembling a valve housing (3), a diaphragm (5) and the other components of the overrun air recirculation valve (1) to form an overrun air recirculation valve cartridge;
- and
- fastening the overrun air recirculation valve cartridge to a fastening flange (15) of a compressor housing (14),
- wherein, during the course of the mounting of the overrun air recirculation valve (1), the diaphragm (5) is radially sealed off at the edge side in an annularly encircling receiving groove (16) of a fastening flange (15) of the compressor housing (14).
