Patent ID: 7588017

Claim:
A fuel delivery module for a vehicle comprising: a reservoir constructed and arranged to be mounted in a fuel tank of a vehicle, the reservoir having an opening in a bottom thereof permitting fuel to enter the reservoir, a fuel pump in the reservoir, the fuel pump including a high pressure portion and a low pressure portion, the fuel pump being constructed and arranged to draw fuel from the reservoir and send fuel from the high pressure portion to an engine of a vehicle, a jet assembly including a jet nozzle having an inlet fluidly connected with the low pressure portion of the fuel pump, and a venturi tube associated with the jet nozzle, the jet assembly being associated with the opening in the reservoir and constructed and arranged so that when a sufficient fuel flow from the low pressure portion of the fuel pump is sent through the jet nozzle and venture tube, fuel is drawn into the reservoir through the opening, and by-pass structure connected between the high pressure portion of the fuel pump and the inlet of the jet nozzle, the by-pass structure being constructed and arranged such that under certain conditions when the flow of fuel from the low pressure portion of the fuel pump alone is insufficient to operate the jet pump assembly, fuel is selectively permitted to flow through the by-pass structure from the high pressure portion of the fuel pump to the inlet of the jet nozzle ensuring that a sufficient flow of fuel is present at the jet assembly to draw fuel into the reservoir.
