Abstract:
1. An integrated jet fluid level shutoff sensor and fuel tank vent assembly for sensing a predetermined level of fuel within a fuel tank while fully venting the fuel tank, comprising: a sensor base section including a sensor inlet for receiving fuel from a fuel supply and a sensor outlet for returning fuel from the sensor; a fuel channel connected in communication between the sensor inlet and sensor outlet, the fuel channel including an outlet orifice and an inlet orifice spaced apart by a cutout section, the outlet orifice being aligned with the inlet orifice to conduct a stream of fuel across the cutout section to the inlet orifice, the cutout section exposing the stream of fuel between the outlet orifice and the inlet orifice to the contents of the fuel tank, whereby fuel in the fuel tank reaching the cutout section will interrupt the stream of fuel, thereby interrupting flow of fuel through the jet sensor; a protective shield having an upper end and a lower end, said upper end mounted to said sensor base section, said protective shield surrounding said cutout section, and said lower end being open to the contents of the fuel tank to permit fuel in the fuel tank to reach the cutout section through said lower end; at least one interior vent channel in the sensor base section for communication with the interior of the fuel tank; and at least one vent outlet port in communication with said at least one interior vent channel to fully vent the fuel tank.
