Definitions

  • This invention relates to nozzle assemblies and more particularly to nozzle assemblies suitable for dispensing liquified petroleum gas.
  • a dispensing nozzle having a connector adapted to couple the nozzle to a tank or the like and valve means operable by a lever to open and close the nozzle characterised by the provision of locking means operable to prevent uncoupling of the connector whenever the lever is in its position which opens the valve.
  • a dispensing nozzle having a connector adapted to couple the nozzle to a tank or the like, a reservoir within the nozzle in communication with the fluid entering the nozzle, a main valve operable to open and close the nozzle, pressure release means operable to reduce the pressure at the main valve at the commencement of opening of the main valve.
  • a dispensing nozzle comprising a body adapted to be connected to a supply of fluid, an outlet through which the fluid is dispensed from the nozzle, a fluid reservoir within the nozzle in communication with the supply of fluid, a main valve normally held closed by the pressure within the reservoir, pressure release means adapted to reduce the pressure at the main valve and means for operating the pressure release means so as to reduce the pressure in the reservoir and then to operate the main valve so as to open the nozzle.
  • the pressure release means is in the nature of a dashpot defined by a fixed cylinder and a movable piston valve.
  • Fig. 1 is a front perspective view of a dispensing nozzle according to one embodiment of the invention.
  • Fig. 2 is a rear perspective view of the dispensing nozzle shown in Fig. 1
  • Fig. 3 is a cross-sectional view of the dispensing nozzle shown in Figs. 1 and 2 with the main valve closed,
  • Fig. 4 is an enlarged, partially cutaway view similar to
  • Fig. 3 but with the main valve open
  • Fig. 5 is an enlarged, cutaway view of the lever locking arrangement prior to engagement
  • Fig. 6 is a view similar to Fig. 5 with the lever locked in the open position.
  • the nozzle assembly shown in the drawings includes a hollow body 10 having a connector piece 11 adapted to be connected to a supply line.
  • the nozzle is operated by lever 12 that pivots about lever pin 13 and which is protected by guard 14.
  • a swivel nut 15 mounted over the outlet end 16 of the nozzle extends rearwardly towards the lever guard 14.
  • the swivel nut 15 rotates on balls 17 that are accessible through ball plug 18.
  • the swivel nut 15 has a threaded insert 19 by means of which the nozzle is connected to a L.P.G. tank of, say, a vehicle (not shown). Whenever the nozzle is open, rotation of the swivel nut 15 with respect of the body 10 is prevented by pin 20 engaging one of recesses 21 formed around the rear face of the swivel nut 15 whenever the nozzle is open.
  • the coupler portion of the nozzle includes a pressure release means comprising a dashpot system that consists of a cylinder 22 and a piston valve 23.
  • a dashpot system that consists of a cylinder 22 and a piston valve 23.
  • the cylinder 22 is located within a valve body 24, the hollow interior of which constitutes the gas reservoir, and is held in position by filter body 25 which supports a filter 26 and which is secured by means of circlip 27.
  • a nose piece 28 is biased towards the position shown in Fig.
  • a nose piece spring 29 positioned between the recessed end face of nose piece 14 and the recessed front face of a slide sleeve 30 that is mounted around the front end of the body 10 and the valve body 24.
  • An "0" ring 31 seals the valve body 24 with respect to the body 10 and slide sleeve spring 32 connected between a rearwardly facing shoulder of the slide sleeve 30 and a forwardly facing shoulder of the valve body 24 acts as a return spring which comes into operation when the nozzle is being disconnected.
  • a piston valve seat 33 located at the downstream end of the valve body 24 is engaged by the front end of the piston valve 23 when the nozzle is closed.
  • An "O" ring 34 at the end of valve body 24 seals the valve body 24 with respect to the centrally located, rearwardly extending projection of the nose piece 28 when the nozzle is open.
  • the nose piece 28 has a gas passageway 35 and an actuating abutment 36.
  • the swivel nut 15 is connected to an adaptor on the L.P.G. tank of a vheicle and in so doing, the nose piece 28 is forced to the right of Fig. 3 against the operation of nose piece spring 29 to close the gap between
  • the trigger lever 12 is then operated by moving its 10 lower end to the right in Fig. 3 whereby its upper end pivots about pin 13 and drives the valve body 24 towards the nose piece 28.
  • the abutment 36 of the nose piece 28 then lifts the front face of the piston valve 23 from its seat 33.
  • the pressure within the dashpot formed by the cylinder 15 22 and piston valve 23 is normally set by flow of L.P.G. from the body 10 through a bleed hole 37 on the axis of the cylinder 22.
  • the piston valve 23 is lifted from its seat 33, the pressure in the dashpot chamber is reduced by leakage through the annular gap described above to enable 20 easy opening of the main valve 23, 33 by further movement of the lever 12.
  • the main valve 23, 33 is fully opened by further movement of valve body 24 towards the nose piece 28 (caused by further movement of lever 12) which moves the valve seat 25 33 away from the front end face of piston valve 23 against the action of spring 32.
  • the pin 20 engages one of the recesses 21 to prevent rotation of the swivel nut 15 .
  • the lever 12 is held in the open position by a latch 41 which mounted on pin 42 in the guard 14 and biased by latch spring 43 - see Figs. 5 and 6.
  • the hooked end 44 of the latch 41 engages latch pin 45 in the end of the lever 12.

Abstract

Un ajutage distributeur comprend un corps (10) pouvant être relié à une source de gaz de pétrole liquéfié par un raccord (11) et au réservoir de gaz d'un véhicule par une insertion filetée (19) dans un écrou tournant (15). Le gaz est appliqué au réservoir à l'intérieur du corps de soupape (24) par le raccord (14) et est livré à travers une soupape principale ayant un siège de soupape (33) et une soupape à piston (23). La soupape à piston (23) et le cylindre de soupape (22) forment un amortisseur "dashpot" mis sous pression par le gaz s'écoulant par le passage (37). Le gaz sort par un écart annulaire entre la soupape à piston (24) et le cylindre de soupape (22) dès que la soupape (23) se sépare de son siège (3) afin de réduire la pression dans le "dashpot", ce qui permet d'ouvrir aisément la soupape principale. L'écrou tournant (15) est retenu par un goujon (20) qui pénètre dans un creux (21) parmi une pluralité de creux formés du côté postérieur de l'écrou lorsque l'ajutage est ouvert.
