Patent number: 11137279Abstract: A liquid level sensor includes a liquid level responsive member that moves in response to changing liquid level, an electrically conductive contact associated with the liquid level responsive member, a circuit including a rectifying element and a) one or more conductive elements, or b) one or more resistive elements or c) one or more conductive elements and one or more resistive elements, wherein the contact is arranged to engage at least one of the elements in a, b, or c, and a power supply. The power supply is adapted to provide a voltage to the circuit causing a current flow in a first direction in the circuit wherein the current flows through the contact and to provide a current flow in a second direction in the circuit wherein the rectifying element prevents current flow through the contact.Type: GrantFiled: January 30, 2018Date of Patent: October 5, 2021Assignee: Walbro LLCInventors: Robby L.

Patent number: 11085407Abstract: In at least some implementations, a fuel supply module includes a reservoir and a fuel pump carried by the reservoir. The reservoir may include a body and a lid that define an internal volume to contain a supply of fuel, and the reservoir may include an inlet through which fuel enters the internal volume and an outlet from which fuel is discharged from the fuel supply module. The fuel pump is carried by the reservoir and has a first inlet communicating with the internal volume to take fuel into the fuel pump from the internal volume and a second inlet spaced above the first inlet relative to the direction of the force of gravity to take fluid or vapors into the fuel pump from the internal volume. The fuel pump includes an outlet from which fluid is discharged for delivery to an engine through the reservoir outlet.Type: GrantFiled: September 1, 2017Date of Patent: August 10, 2021Assignee: Walbro LLCInventors: Eric D. Anderson, Travis P. Baur, Elton J. Fisch, Cyrus M. Healy, Kevin L. Israelson, Gerald J. LaMarr, Jr., Robby L. Linton, Edward J. Talaski

Patent number: 10907537Abstract: In at least some implementations, an ignition system for a combustion engine includes analog circuit components arranged to control ignition events at an engine speed below a first threshold of engine speed and a microprocessor to control ignition events at engine speeds higher than the first threshold. Hence, ignition can be controlled at lower engine cranking speeds to facilitate starting the engine at lower engine rotational speeds.Type: GrantFiled: March 19, 2018Date of Patent: February 2, 2021Assignee: Walbro LLCInventors: Martin N. Andersson, Cyrus M. Healy, Robby L. Linton

Publication number: 20200269409Abstract: A power tool may include an engine, a tool driven for movement by the engine, a brake mechanism coupled to the tool, a charge forming device coupled to the engine and a transmission member operably coupled to the brake mechanism and a throttle valve of the charge forming device. The brake mechanism inhibits movement of the tool in an engaged position of the brake mechanism and permits movement of the tool in a disengaged position of the brake mechanism. The charge forming device is coupled to the engine to provide a combustible fuel and air mixture to the engine, and the throttle valve is movable between a first position and a second position. The transmission member is operably coupled to the brake mechanism and the throttle valve so that the throttle valve is moved away from the first position when the brake mechanism is moved to the engaged position.Type: ApplicationFiled: September 28, 2018Publication date: August 27, 2020Inventors: Matthew A. Braun, Cyrus M. Healy, Robby L. Linton

Patent number: 10408182Abstract: A fuel system that in at least some implementations includes a carburetor having a fluid passage, a solenoid, a valve, a driver circuit and a control circuit. The valve may be moved by the solenoid between an open position permitting fluid flow through the fluid passage and a closed position at least partially inhibiting fluid flow through the fluid passage. The driver circuit and control circuit are communicated with the solenoid to contribute to providing power to the solenoid and controlling actuation of the solenoid. The driver circuit and control circuit provide a first magnitude of power to the solenoid to initially change the solenoid from its closed position to its open position and a second magnitude of power to maintain the solenoid in its open position wherein the second magnitude of power is less than the first magnitude.Type: GrantFiled: March 24, 2017Date of Patent: September 10, 2019Assignee: Walbro LLCInventors: Gerald J. LaMarr, Jr., Robby L. Linton
