other Embodiment approach

[0046] Other implementations are also possible. For example, timers may include discrete components and / or other integrated timers (eg, 556 timers). Or for example, control circuit 22 may be configured to provide power to solenoid 26 using any suitable frequency and / or amplitude modulation technique and using digital and / or analog components.

[0047] Accordingly, cutout solenoids in fuel systems have been disclosed. The cut-off solenoid can minimize blowback or flashback because fuel stops flowing in the fuel circuit when the engine is shut off. Additionally, several embodiments have been disclosed for controlling the amount of energy used by the trip solenoid and minimizing the heat dissipated thereby. The power consumed by the solenoid may be controlled by a control circuit, which may include, but is not limited to, an embodiment having a microcontroller and one or more timers. Accordingly, the drive circuit and control circuit may provide a first amount of power to the ...

Abstract

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.

Description

[0001] REFERENCE TO CO-PENDING APPLICATIONS [0002] This application claims the benefit of US Provisional Application No. 61 / 860,301, filed July 31, 2013, which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure generally relates to fuel cutoff solenoids. Background technique [0004] Some fuel systems include solenoid valves to control fuel flow. The solenoid consumes power and when energized generates and transfers heat to adjacent components. This is inefficient from a power standpoint and the heat may affect the operation or performance of adjacent components and / or fluids contained or flowing within adjacent components. Contents of the invention [0005] A fuel system in at least some embodiments includes a carburetor having a fluid passage, a solenoid, a valve, a drive circuit, and a control circuit. The valve can be moved by a solenoid between an open position allowing fluid flow through the fluid passage and a c...
