Patent number: 9540976Abstract: A particle filter (2) for filtering exhaust gas in an internal combustion engine includes a housing and a filter element. A simplified installation and/or simplified replacement of the filter element (5) and/or improved sealing of the housing (4) results if the filter element (5) is supported in an inner jacket (9), which is supported radially in an outer jacket (12) and is arranged so as to be axially movable in the outer jacket (12). The inner jacket (9) is axially supported on a ring (24), which is supported axially on a cover (22) that closes an installation opening (20) of the housing (4) via at least one supporting element (25) in order to transmit pressure forces. A muffler (1) is provided having such a particle filter (2), wherein a section of a muffler housing (3) of the muffler (1) forms the housing (4) of the particle filter (2).Type: GrantFiled: May 7, 2013Date of Patent: January 10, 2017Assignee: EBERSPÄCHER EXHAUST TECHNOLOGY GMBH & CO.

Patent number: 9399938Abstract: An exhaust gas treatment device (1) includes a combustion waste gas inlet pipe (2), an outlet pipe, an essentially gas-tight inner housing (7) fluidically connected with the inlet pipe and fluidically connected with the outlet pipe. The inner housing receives a particle filter (4). A connection element (9) is arranged in a connection area (8) of the inner housing. The connection area fluidically faces the outlet pipe (3), for mechanically connecting the particle filter with the inner housing. An oxidation catalytic converter (5) is arranged upstream of the particle filter in the inner housing for catalyzing an oxidation reaction of the combustion waste gas. A counterpressure monitoring point (10, 11, 12) is provided fluidically between the oxidation catalytic converter and the connection element for measuring a counterpressure exerted by the particle filter during the operation of the treatment device. An internal combustion engine (24) is provided with the treatment device.Type: GrantFiled: September 25, 2014Date of Patent: July 26, 2016Assignee: Eberspächer Exhaust Technology GmbH & Co.

Patent number: 8646573Abstract: The present invention relates to an exhaust gas treatment device for an exhaust system of an internal combustion engine, more preferably of a road vehicle with a housing, in which at least one exhaust gas treatment element is arranged and mounted by means of a bearing mat and with an outlet pipe which is fluidically connected to an outlet chamber formed in the housing. The risk of a contamination of the bearing mat with water can be reduced with a separating bottom which is arranged in the housing and separates the outlet chamber from a collecting chamber. The separating bottom includes several passage openings through which the outlet chamber is fluidically connected to the collecting chamber and which are each enclosed by a collar protruding into the outlet chamber.Type: GrantFiled: February 23, 2011Date of Patent: February 11, 2014Assignee: J.

Patent number: 8336301Abstract: The present invention relates to an exhaust gas treatment unit for an exhaust system of a combustion engine, in particular of a motor vehicle, includes a housing, a plurality of exhaust gas treatment elements, which are arranged in the housing and through which a parallel flow is possible. The unit further includes an outlet nozzle, which penetrates a side face of the housing, and an outlet space disposed in the housing, whereby the outlet of at least one of the exhaust gas treatment elements opens into the outlet space. The rigidity and/or effectiveness of the exhaust gas treatment unit can be improved by means of a funnel body disposed in the outlet space, and comprising a funnel surface which is permeable to exhaust gas. The funnel body connects an outlet end of one of the exhaust gas treatment elements with the outlet nozzle.Type: GrantFiled: May 5, 2009Date of Patent: December 25, 2012Assignee: J.
