Patent number: 6659120Abstract: A vent control system having a closed biased vent valve is used to separate vapor and/or air from a liquid in an enclosed chamber. The closed biased vent valve has a float having an upwardly extending float arm which cooperates with a lever arm of the closed biased vent valve to prevent unintended release of vapor or liquid from the enclosed chamber. The upwardly extending float arm and the lever arm are coupled to one another when the float is located beneath a designated level in the enclosed chamber and are decoupled from one another when the float rises above the designated level. The vent control system is much less susceptible to vibration induced vent opening than a traditional vent valve. The vent control system is well suited for use in a fuel vapor separator that includes a housing having the enclosed chamber formed within it.Type: GrantFiled: August 9, 2002Date of Patent: December 9, 2003Assignee: Bombardier Motor Corporation of AmericaInventors: Richard P.

Patent number: 6453877Abstract: A fuel delivery system uses a single electric fuel pump to deliver fuel to a fuel injected engine and returns excess fuel to the single electric fuel pump via a vapor separator and two pressure regulators. A primer bulb draws fuel from a fuel tank with a fuel supply line and transfers the fuel to the single electric fuel pump. The single electric fuel pump delivers fuel to a fuel rail assembly, which enables fuel to be distributed to each fuel injector during engine operation. A fuel return line connects the fuel rail assembly to the single electric fuel pump via the vapor separator to remove excess fuel from the fuel rail assembly and to transfer the excess fuel back to the single electric fuel pump for re-circulation. The first pressure regulator maintains a substantially constant pressure within the fuel injectors while the vapor separator purges entrained gas from the excess liquid fuel to avoid vapor lock.Type: GrantFiled: November 28, 2000Date of Patent: September 24, 2002Assignee: Outboard Marine CorporationInventors: Peter E.
