Definitions
- An acceptable gasoline dispensing nozzle must be readily adaptable to be received by all or virtually all standard tank fill pipes for use by untrained and trained personnel. It is contemplated that ultimately governmental regulations and controls will require standardization of all gasoline tank fill pipes with controls of vapor emission during fuel supply of all volatile fuels as well as increased safety standards.
- the connecting relationship between the supplying gasoline dispenser and the receiving vehicle tank fill pipe is the gasoline fill nozzle which usually is connected to the gasoline pump by means of a flexible hose line. It is most desirable to retain, where possible, at least many of the accepted conventional features or systems presently in use provided they may be integrated and interrelated with a tank fill pipe sealing member to provide safety features in which disengagement of the fill nozzle with the tank fill pipe will automatically terminate fluid flow. It is desirable that the nozzle geometry should be essentially the size and shape of those presently being used without any increased flow resistance. It is further desirable that the nozzle derive its power for operation either from the operator or from forces generated by the flowing fluid without dependence on any outside power source. Furthermore, there should be elimination of any possibility of sparking which may occur due to the generation of an electrical potential resulting from the flow of fluid. Preferably some thermal insulation may be desirable to reduce the discomfort experienced by an operator during cold weather operation.
- a fluid sensing system for a self-contained automatic shutoff.
- Several systems are available such as: static pressure in which cutoff is effected by small static pressure differentials when gasoline rises or covers the nozzle tip which translates pressure differential to operate a trip mechanism, buoyancy in which a float rises in a nozzle tip to trip a mechanism, vapor pressure in which a nozzle sealed in a fill pipe will transmit vapor pressure to a trip mechanism, and a vacuum trip in which the flow of gasoline through an air ejector develops air flow through a passage in the nozzle and air flow interruption increases the vacuum developed thereby tripping a shutdown mechanism.
- An additional feature desirable in a nozzle for dispensing gasoline is to prevent flow in the absence of positive fluid pressure to prevent the delivery hose from being emptied at the exupon tank fill or disengagement of the seal intentionally or inadvertently from the tank fill pipe.
- a further objective of this invention is to provide an automatic trip safety fill nozzle with a preconditioning and shutoff linkage to control a valve mechanism before fluid flow maybe initiated and for terminating fluid flow in the event of (a) tank fill, (b) seal release, loss of fluid pressure, among other occurrences.

- a fill pipe sealing assembly 31 is secured to the nozzle tube 15 through the collar 31 that is fixed in position 32 to retain the coil spring 33 in encircling position about tube 15.
- a fill pipe sealing member 34 made of any suitable resistant material which will not deteriorate readily when subjected to gasoline and gasoline vapors is yieldably biased by spring 33 into engagement with the intumed flange 20 of a fill pipe 19 when the discharge tube 15 is inserted properly and releasably latched as shown in FIG. 1.
- the face 35 of the seal member 34 is preferably resilient or spongy to obtain maximum seating of is preferably resilient or spongy to obtain maximum seating of the seal member and the intumed flange 20.
- a valve mechanism preconditioning link 36 is pivotally connected at 37 to the sealing member 34 at one end thereof and to a pivotal bell crank 38 at the other end thereof. Upon positioning the sealing member 34 from the unseated to the seated position, as shown in FIG. 2, bell crank 38 will rotate or pivot in a counterclockwise direction.
- the inlet passage 12 is provided with a handle 39 which may be suitably insulated, preferably on the exterior, to make the handle more comfortable to use during cold weather.
- An inlet valve assembly 40 shown in the seated position in FIG. 2, has a valve member 41 secured to valve assembly plunger 42 which extends through a packing gland 43 in the body boss 44 with a coil spring 45 exerting pressure against the packing 43 through the threaded packing nut 4l6.
- the upper end of the valve assembly in the inlet passage 12 has a coil spring 47 exerting pressure downwardly on the valve 41 with the spring being retained in the inlet valve assembly chamber 48 formed in the spring cover 49 that is threadably retained in the nozzle body.
- valve orifice 50 is restricted and fonns with the circumferential opening 51 a Venturi effect upon fluid flowing through the restricted opening 50 to create a suction through the passage 52 communicating with the circumferential opening 51.
- Passage 52 leads to the suction chamber 53 in the body adjacent to the valve assembly. Fluid will flow in the valve assembly open condition through inlet passage 12 through the orifice 50 into the chamber 54' before passing to the discharge passage 14 and tube 15.
- an inlet pressure chamber 55 partially formed in the closure cap 56 secured by bolts 57 to the nozzle body with a pressure-responsive diaphragm 58 extending through the chamber 55.
- Fluid entering inlet passage 12 will flow through the passage 55' into the fluid pressure chamber 55.
- a diaphragm connected plunger 59 extends downwardly from the diaphragm housing 60 through the opening 61 into the vacuum chamber 53.
- Coil spring 62 will normally urge the diaphragm 58 upwardly unless the force of spring 62 is overcome by the inlet pressure of the fluid to be dispensed.
- diaphragm 58 Upon proper pressure being exerted in chamber 55 by the fluid entering inlet passage 55, diaphragm 58 will be depressed urging plunger 59 downwardly into vacuum chamber 53 to engage the upper end 63 of plunger 64 that is connected to vacuum diaphragm 65 supported in the vacuum chamber 53.
- the ball cage 65' includes the cage ring 66 for engaging the balls 67 in the seated position about the depending suction diaphragm plunger 64.
- the plunger 64 is slidably guided in its movement within the outer trip rod or plunger 68 that is movable within the bore 69 formed in the body depending boss 70 forming an annular chamber for receiving the coil spring 71 which which normally urges plunger 68 upwardly in the ball cage 65'.
