Patent number: 8746207Abstract: An internal combustion engine includes a muffler configured to reduce exhaust gas noise. The muffler has a housing defining an interior and an exterior. A choke valve is configured to control a flow of air in a carburetor and a thermally responsive element is coupled with the choke valve and configured to move the choke valve in response to a temperature change in the thermally responsive element. A thermally conductive member has a first portion positioned in the interior of the muffler and extending through the muffler housing to the exterior of the muffler, and a second portion positioned exteriorly of the muffler and coupled to the thermally responsive element. The thermally conductive member is configured to conduct heat from exhaust gases within the muffler to the thermally responsive element.Type: GrantFiled: July 3, 2013Date of Patent: June 10, 2014Assignee: Briggs and Stratton CorporationInventors: Christopher J. Drew, David W. Branski, Chad J. Gartzke, William H. Mayer, Benjamin R. Miller, Dawn N. Traynor, Gene Zimmerman, Jean-Paul Benjamins

Patent number: 8495995Abstract: An internal combustion engine includes a muffler configured to reduce exhaust gas noise, a choke valve configured to control a flow of air in a carburetor, a thermally responsive element coupled with the choke valve and configured to move the choke valve in response to a temperature change in the thermally responsive element, and a thermally conductive member. The muffler has a housing defining an interior and an exterior. The thermally conductive member has a first portion positioned in the interior of the muffler in direct contact with the exhaust gases and extends through the muffler housing to the exterior of the muffler. The thermally conductive member also has a second portion positioned exteriorly of the muffler and coupled to the thermally responsive element, the thermally conductive member configured to conduct heat from exhaust gases within the muffler to the thermally responsive element.Type: GrantFiled: June 23, 2010Date of Patent: July 30, 2013Assignee: Briggs and Stratton CorporationInventors: Christopher J. Drew, David W. Branski, Chad J. Gartzke, William H. Mayer, Benjamin R. Miller, Dawn N. Traynor, Gene Zimmerman, Jean-Paul Benjamins

Patent number: 8413760Abstract: A muffler for an internal combustion engine includes a first shell includes a flexible portion, an intake conduit, and a second shell coupled to the first shell. The intake conduit extends outwardly from the first shell and is configured to be inserted into an exhaust port of an engine. The flexible portion surrounds the intake conduit. Upon attachment to the engine, compression force is stored via elastic deflection of the flexible portion of the first shell, thereby pressing the intake conduit into the exhaust port such that a seal is formed.Type: GrantFiled: July 16, 2012Date of Patent: April 9, 2013Assignee: Briggs & Stratton CorporationInventors: Christopher J. Drew, John R. Schneiker

Patent number: 8251173Abstract: An engine includes an exhaust conduit having an exhaust port on an end of the exhaust conduit. The exhaust conduit has an angled inside surface that has a cross section that widens toward the exhaust port. The engine further includes a muffler having a housing with an intake pipe. The intake pipe is inserted through the exhaust port such that the intake pipe is wedged into the angled inside surface of the exhaust conduit.Type: GrantFiled: July 23, 2009Date of Patent: August 28, 2012Assignee: Briggs & Stratton CorporationInventors: Christopher J.
