Abstract
The invention relates to a silencer for exhaust systems of motor vehicles with an internal combustion engine. The silencer includes an exhaust gas flow pipe for guiding exhaust gas with an exhaust gas inlet opening, an exhaust gas outlet opening having a flow connection to the exhaust gas inlet opening, and a longitudinal center axis. It furthermore has at least one actuable adjustment body for influencing the flow of the exhaust gas in the exhaust gas flow gas pipe, the at least one adjustment body being arranged downstream of the exhaust gas inlet opening. Moreover, the silencer includes at least one bypass channel, which has a flow connection to the exhaust gas flow pipe, runs past the at least one adjustment body and has an exhaust gas outlet opening.
Claims22
A silencer for exhaust systems of motor vehicles with an internal combustion engine, the silencer comprising:
- an exhaust gas flow pipe for guiding exhaust gas with at least one exhaust gas inlet opening, at least one exhaust gas outlet opening, which has a flow connection to the at least one exhaust gas inlet opening, and a longitudinal center axis;
- at least one actuable adjustment body to influence a flow of the exhaust gas in the exhaust gas flow pipe, wherein the at least one actuable adjustment body is arranged downstream of the at least one exhaust gas inlet opening, and said at least one actuable adjustment body is movable between an open position and a closed position, said at least one actuable adjustment body being mounted in an adjustment body receiver;
- and
- at least one bypass channel defined by a bypass body, which has a flow connection to the exhaust gas flow pipe, and said at least one bypass channel has at least one exhaust gas outlet opening, said bypass body being a separate insert from said exhaust gas flow pipe, at least a portion of said bypass body extending through said adjustment body receiver.
A silencer arrangement for exhaust systems of motor vehicles with an internal combustion engine, comprising at least one silencer, the at least one silencer comprising:
- an exhaust gas flow pipe for guiding exhaust gas with at least one exhaust gas inlet opening, at least one exhaust gas outlet opening, which has a flow connection to the at least one exhaust gas inlet opening, and a longitudinal center axis;
- an adjustment body receiver comprising a bypass body opening;
- at least one actuable adjustment body to influence a flow of the exhaust gas in the exhaust gas flow pipe, said at least one actuable adjustment body being connected to said adjustment body receiver, wherein the at least one actuable adjustment body is arranged downstream of the at least one exhaust gas inlet opening, and said at least one actuable adjustment body is movable between an open position and a closed position;
- and
- a bypass body comprising at least one bypass channel, which has a flow connection to the exhaust gas flow pipe, and said at least one bypass channel has at least one exhaust gas outlet opening, said bypass body opening receiving at least a portion of said bypass body, said bypass body being a separate and distinct insert structure from said exhaust gas flow pipe.
A silencer for exhaust systems of motor vehicles with an internal combustion engine, the silencer comprising:
- an exhaust gas flow pipe for guiding exhaust gas with at least one exhaust gas inlet opening, at least one exhaust gas outlet opening, which has a flow connection to the at least one exhaust gas inlet opening, and a longitudinal center axis;
- at least one actuable adjustment body to influence a flow of the exhaust gas in the exhaust gas flow pipe, wherein the at least one actuable adjustment body is arranged downstream of the at least one exhaust gas inlet opening, and said at least one actuable adjustment body is movable between an open position and a closed position;
- and
- a bypass body defining at least one bypass channel, said at least one bypass channel being in fluid communication with said exhaust gas flow pipe, said at least one bypass channel having at least one exhaust gas outlet opening, said bypass body being a separate and distinct insert from said exhaust gas flow pipe, said bypass body comprising a plurality of flow chambers.
