Abstract
A self-aligning jet pump assembly for draining a liquid trap has a jet pump nozzle and a nozzle carrier that are self-aligning.
Claims20
A jet pump assembly comprising:
- a unitary nozzle carrier having a wall with an entrance port;
- wherein the nozzle carrier has a longitudinal passage extending through the nozzle carrier and in fluid communication with the entrance port;
- a unitary venturi nozzle having an inlet and a nozzle tip forming an outlet;
- wherein the venturi nozzle is configured to fit to the nozzle carrier in the longitudinal passage so that alignment of a longitudinal axis of the nozzle with a longitudinal axis of the venturi nozzle is affected only by the fit of the nozzle carrier to the venturi nozzle;
- and wherein the nozzle tip extends past the entrance port and is in fluid communication with the entrance port when the venturi nozzle is fit to the nozzle carrier.
2 more elements
A jet pump assembly comprising:
- a nozzle carrier having an entrance port;
- wherein the nozzle carrier has a longitudinal passage extending through the nozzle carrier and in fluid communication with the entrance port;
- wherein the nozzle carrier has a carrier portion extending from a first end to the entrance port, and a diffuser portion extending from the entrance port to a second end opposite the first end;
- a venturi nozzle having a body portion with an inlet, and a nozzle portion with a nozzle tip forming an outlet;
- wherein the body portion is configured to fit to the carrier portion in the longitudinal passage so that alignment of a longitudinal axis of the venturi nozzle with a longitudinal axis of the nozzle carrier is dependent only on the carrier portion and the venturi nozzle;
- and wherein the nozzle portion extends past the entrance port with the nozzle tip directed into the diffuser portion when the body portion is fit to the carrier portion.
3 more elements
A jet pump assembly comprising:
- a unitary nozzle carrier having a wall with a first entrance port;
- wherein the nozzle carrier has a longitudinal passage extending through the nozzle carrier and in fluid communication with the first entrance port;
- wherein the wall has an additional entrance port extending through the nozzle carrier in fluid communication with the longitudinal passage, and spaced angularly from the first entrance port;
- a unitary venturi nozzle having an inlet and a nozzle tip forming an outlet;
- wherein the venturi nozzle is configured to fit to the nozzle carrier in the longitudinal passage so that alignment of a longitudinal axis of the nozzle with a longitudinal axis of the venturi nozzle is affected only by the fit of the nozzle carrier to the venturi nozzle;
- wherein the nozzle tip extends past the first entrance port and is in fluid communication with the entrance port when the venturi nozzle is fit to the nozzle carrier;
- and
- wherein the venturi nozzle has a first stepped shoulder configured to abut an outer end surface of the nozzle carrier when the venturi nozzle is fit to the carrier portion in the longitudinal passage so that a clearance exists between the nozzle tip and the nozzle carrier.
