NOZZLE AND KEYED FLUSH FACE RECEIVER
First Claim
1. A fluid nozzle comprising:
- a fluid inlet formed in a nozzle base;
a poppet rigidly coupled with and extending outward from the nozzle base, the poppet having a poppet end surface;
a seal ring having a seal ring end surface disposed between a pull-back collar end surface and the poppet end surface, where the seal ring is movable between a first position that prevents fluid flow through the fluid nozzle, and a second position that forms an annular fluid outlet that allows fluid flow through the fluid nozzle;
a tubular ball ring disposed around an outer surface of the seal ring, the ball ring comprising at least one opening for housing a tumbler, where the tumbler is configured to engage a surface feature of a keyed receiver and selectively allow the seal ring to move to the second position or to maintain the seal ring in the first position in response to the at least one opening being positioned to correspond with the surface feature.

Abstract
An apparatus and system are disclosed for fluid transfer. The apparatus includes a fluid nozzle having a nozzle base. A poppet is rigidly coupled with the nozzle base. The poppet includes a poppet end surface. The fluid nozzle also includes a seal ring having a seal ring end surface disposed between a pull-back collar end surface and the poppet end surface. The seal ring is movable between a first position that prevents fluid flow through the fluid nozzle, and a second position that forms an annular fluid outlet that allows fluid flow through the fluid nozzle. The fluid nozzle also includes a tubular ball ring disposed around an outer surface of the seal ring. The ball ring includes at least one opening for housing a tumbler, which is configured to engage a surface feature of a keyed receiver. The system includes a fluid receiver and the fluid nozzle.

12. An apparatus for selectively allowing fluid flow, the apparatus comprising:
-
a base forming a fluid inlet; a nose collar extending from the base and forming a fluid outlet, the base and nose collar forming a fluid flow path; and a ball ring slidably disposed within the nose collar, the ball ring comprising a plurality of openings, where each of the plurality of openings is configured to maintain a tumbler or to remain vacant, and where the ball ring locks positionally with reference to the nose collar in response to one of the plurality of openings having a tumbler that is urged towards the nose collar by a surface feature of a keyed receiver. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A fluid transfer system comprising:
-
a fluid nozzle comprising; a base forming a fluid inlet; a nose collar extending from the base and forming a fluid outlet, the base and nose collar forming a fluid flow path; and a ball ring slidably disposed within the nose collar, the ball ring comprising a plurality of openings, where each of the plurality of openings is configured to maintain a tumbler or to remain vacant, and where the ball ring locks positionally with reference to the nose collar in response to one of the plurality of openings having a tumbler that is urged towards the nose collar by a surface feature of a keyed receiver; and where the keyed receiver comprises; a tubular cylinder having an inlet and an outlet, where the tubular cylinder has a keyed outer surface that comprises the surface feature, where the surface feature extends annularly around the surface of the tubular cylinder.
