Abstract
A fuel pump module includes a reservoir having a jet pump attached to the outer surface of the reservoir. The jet pump includes a pump body which is ultrasonically welded to the reservoir and a jet nozzle which extends from the pump body towards an inlet to the reservoir. An alignment device or the jet pump engages an alignment device on the reservoir to ensure that the jet nozzle will be in accurate alignment with the inlet of the reservoir.
Claims27
A fuel pump module comprising:
- a reservoir having an inlet and an outlet;
- a fuel pump disposed within said reservoir, said fuel pump being operable to pump fuel from said reservoir through said outlet leading from said reservoir;
- a pressure regulator assembly in communication with said outlet for maintaining a specified fluid pressure at said outlet;
- a jet pump attached to an outer surface of said reservoir, said jet pump being in fluid communication with said pressure regulator assembly, said jet pump being operably to pump fluid from outside said reservoir through said inlet and into said reservoir.
A method of attaching a jet pump having a jet pump body and a jet nozzle extending from said jet pump body to a reservoir having an inlet, said method comprising:
- providing a first alignment device on said jet pump;
- providing a second alignment device on said reservoir;
- aligning said jet nozzle with said inlet of said reservoir by engaging said first alignment device with said second alignment device;
- and
- securing said jet pump to said reservoir.
A fuel pump module comprising:
- a jet pump defining a jet pump body, a jet nozzle extending from said jet pump body and a first alignment device;
- a reservoir defining a second alignment device;
- wherein:
- said jet pump is attached to said reservoir by engaging said first alignment device with said second alignment device and then securing said jet pump body to said reservoir.
