Abstract
A silencer for a vehicle includes a noise dampening mesh material and a silencer housing component forming a receptacle for the noise dampening mesh material. The silencer housing component includes an outer wall and an end wall. The outer wall extends circumferentially around a center axis of the silencer housing component. The end wall forms a concavity. A retarding structure including at least one wall is arranged in the concavity and projects from the end wall. The retarding structure is configured to reduce a rate of gas egress through gas outlet passages of the silencer.
Claims18
A silencer for a pneumatic component for a vehicle, the silencer comprising:
- a noise dampening mesh material;
- a silencer housing component defining a receptacle for the noise dampening mesh material, the silencer housing component comprising:
- an outer wall extending circumferentially around a center axis of the silencer housing component, the outer wall comprising a first axial end and a second axial end, wherein a mounting structure for mounting the silencer housing component is arranged at the first axial end of the outer wall, wherein several gas outlet passages are formed through the silencer housing component in at least the outer wall;
- an end wall extending from the second axial end of the outer wall towards the center axis;
- and
- a retarding structure configured to reduce a rate of gas outflow through the several gas outlet passages during at least part of an exhaust operation, the retarding structure comprising at least one wall arranged in a concavity, wherein the concavity is formed by the end wall, and wherein the retarding structure projects from the end wall towards the first axial end.
A method of exhausting gas in a vehicle, the method comprising:
- exhausting the gas through a silencer, wherein the silencer comprises a silencer housing component defining a receptacle for a noise dampening mesh material, the silencer housing component comprising:
- an outer wall extending circumferentially around a center axis of the silencer housing component, the outer wall comprising a first axial end and a second axial end, wherein a mounting structure for mounting the silencer housing component is arranged at the first axial end of the outer wall, wherein several gas outlet passages are formed through the silencer housing component in at least the outer wall;
- an end wall extending from the second axial end of the outer wall towards the center axis;
- and
- a retarding structure comprising at least one wall arranged in a concavity wherein the concavity is formed by the end wall and wherein
- the at least one wall projects from the end wall towards the first axial end;
- wherein exhausting the gas comprises reducing a rate of gas outflow through the several gas outlet passages during at least part of an exhaust operation by the retarding structure.
