Fuel dispensing nozzle assembly
First Claim
1. A fuel system nozzle for use with a fuel dispensing system including a fuel dispenser and a fuel dispensing hose, comprising:
- a housing having at least one opening located at one side thereof;
a trigger located on the housing;
a dispensing valve selectively removable from within said housing and through said at least one opening, said dispensing valve selectively coupleable to said fuel dispensing hose;
a spout member located substantially opposite said at least one opening;
means for maintaining said dispensing valve within said housing, said maintaining means adapted to withstand application of a predetermined pulling force tending to separate said dispensing valve from within said housing, so that when a pulling force greater than said predetermined force is applied between said spout and said dispensing hose, said maintaining means will fracture and said valve will separate from said housing and stay with said dispensing hose; and
a linear member coupled to said trigger and disposed in said housing, said linear member located proximate to said dispensing valve such that activation of said trigger translates via said linear member to cause said dispensing valve to open.

Abstract
A fuel dispensing nozzle including three calculated break points is provided. The first break point is provided in the spout which is calculated to fracture upon application of a force orthogonal to the axial direction of the spout. The nozzle comprises a housing having at least one opening for a dispensing valve to be selectively removably received within. A coupling or maintaining member is provided for maintaining the dispensing valve within the housing. The maintaining member is adapted to withstand application of a pre-determined force tending to separate the dispensing valve from the housing. The maintaining member allows separation of the housing and dispensing valve when the pre-determined force is exceeded. This maintaining member is the second break point. The third breakaway feature is provided in the construction of the housing which is designed to fracture prior to fracture of the gas pump or hose if the first or second break points do not fracture.

20. A fuel dispensing nozzle for use with a fuel dispensing system including a fuel dispenser and a fuel dispensing hose, comprising:
-
a housing having at least one opening located at one side thereof; a dispensing valve selectively removable from within said housing and through said at least one opening; a spout member located substantially opposite said at least one opening; said dispensing valve releasing from said housing upon application of a pulling force across said spout and said fuel dispensing hose greater than a predetermined pulling force in a direction axial to fluid flow within said dispensing valve; and said spout member having a substantially annular location therealong defined by a plurality of aperatures there-through and adapted to selectively fracture upon application of a torque across said spout and said fuel dispensing hose greater than a predetermined torque in a direction substantially orthogonal to fluid flow through said spout member. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

- 31. A fuel dispensing nozzle comprising a house having at least one aperture located at a first end thereof, a dispensing valve selectively removable from within said housing through said at least one aperature, and a spout member for dispensing fuel located at a second end of said housing, said spout member having a substantially annular location therealong defined by a series of circumferentially disposed aperatures and adapted to selectively fracture along said annular location defined by said aperatures upon application of a torque greater than a predetermined torque.

36. A fuel dispensing nozzle, comprising:
-
a housing having at least one opening; a dispensing valve selectively removable from within said housing and through said at least one opening; means for maintaining said dispensing valve within said housing, said maintaining means adapted to withstand application of a predetermined forced tending to separate said dispensing valve from within said housing; and said housing and said dispensing valve each comprising a flange, and said maintaining means including a ring with a plurality of stubs thereon, said stubs being arranged to engage said flanges, thereby preventing separation of said dispensing valve from said housing. - View Dependent Claims (35)
