Patent number: 10215130Abstract: A choke system for an internal combustion engine includes a carburetor having a choke valve disposed in a passage; a cooling fan providing a variable air flow; an air vane moveable in response to the variable air flow; an air vane linkage coupling the air vane to the choke valve, the air vane linkage operating the choke valve by the movement of the air vane; a manually operated choke control; an override linkage coupling the choke control to the choke valve; and a thermally responsive member configured to engage the override linkage to retain the choke in a partially open position above a threshold temperature. The choke control may be moved to a first position in which the choke control overrides the thermally responsive member and the air vane linkage to maintain the choke valve in a closed position.Type: GrantFiled: February 10, 2012Date of Patent: February 26, 2019Assignee: Briggs & Stratton CorporationInventors: Michael R. Visuri, Jeff J. Steenbergen, Timothy J. Kwiatkowski, Adam J. Hellman, Andrew J. Perez, Casey E. Groh

Patent number: 10167766Abstract: An engine assembly includes a crankcase, shaft, blower housing, and cooling fan. The shaft is rotatably coupled to the crankcase and defines a rotational axis. The blower housing includes an internal space. The cooling fan is disposed within the internal space, includes a plate defining an upper surface, and is positioned to rotate with the shaft about the rotational axis. The cooling fan includes a band having an inner band radius and an outer band radius. The cooling fan includes a plurality of reversed fins extending between the band and the upper surface and between a root adjacent to the rotational axis and a tip adjacent to the outer band radius, each fin offset at an angle measured in a counterclockwise direction from a plane passing through the rotational axis and the tip to a plane passing through the root and the tip when viewed from above the cooling fan.Type: GrantFiled: May 12, 2016Date of Patent: January 1, 2019Assignee: Briggs & Stratton CorporationInventors: Brett Birschbach, Rodney John Balzar, Jeffery P. Feist, Casey E. Groh, Brian Johnson, Randall J. Klotka, Darwin A. Podhola, Ryan Sullivan, Matt Martinek, Brian Paul

Patent number: 9429107Abstract: A choke system for an internal combustion engine includes a carburetor having an air intake, a choke valve disposed in the air intake, and a choke lever coupled to the choke valve, wherein the choke valve is movable between a closed position and an open position, a mechanical linkage coupled to the choke lever, and a solenoid attached to the carburetor and coupled to the mechanical linkage so activation of the solenoid moves the choke valve, wherein the solenoid is activated in response to activation of a starter system of an internal combustion engine, thereby moving the choke valve via the mechanical linkage to the closed position.Type: GrantFiled: February 22, 2013Date of Patent: August 30, 2016Assignee: Briggs & Stratton CorporationInventors: Casey E.
