2,802,491 Patented Aug. 13, 1957 2 I the main valve 2 is associated with a piston 9 as de scribed in that application.

The by-pass 11 leads to two injectors 12a and 12b and to two pressure intakes 13aand 13b which are located at different levels'in the tank to be filled. The intakes 13a and 13b are connected to the cylinder9b at different heights by the conduits 15a. and 15b.

Finally, a cock 5 controls a by-pass 1c of the conduit 1 supplying the liquid, as described in the parent application; j

The operation of this device is as follows:

'In orderto fill the tank, the cock 5 is opened and the pressure liquid, by acting on the face 9d, lifts the piston 9 and the valve 2. The opening of the said valve 2 en-. ables the liquid to penetrate into the tank and into the conduit 11. The jets 12a and 12b send forth streams of substantially cylindrical shape, the cross-section of which is substantially equal to the cross-section of the orifices of the jets 12a and 12b and which streams strikethe pressure intakes 13a and in the preceding examples.

The pressures produced in the intakes 13a and 13b are transmitted via the conduit 15a and 15b to the chamber 9e. The cock 5 is now closed. The intakes 13a and 13b maintain within the chamber 9e a pressure which suffices to keep the valve 2 open despite the thrust exerted on the piston by the liquid coming from the conduit 1. When the liquid level reaches the ejector 12b, the pressure of the intake 13b falls and the liquid within the chamber 9e is urged through the conduit 15b which acts as an escape and causes the pressure to .fall :in the chamber 9e., The valve 2 closes until the piston .9'blocks the conduitlSb and the flow therefore continues. at reduced speed until the ejector 12a is in its turn immersed in the liquid. Atthis moment the pressure of the intake 1 3a falls, the liquid inthe chamber 9e is evacuated through the conduit 15a, and the valve 2 is completely closed;

It should be pointed out that the by-pass 1c and th cock 5 might be eliminated, a spring being then provided in the chamber 9e, to urge the valve towards its open position. The mere force of the said spring is alone insuflicient to prevent the closure of the valve 2 when the flowv of liquid through the conduit 1 is normal. On the other hand, the force of this spring alone is sufiicient to open the valve 2 when the pressure of the fluid in that part of the main conduit 1 which is situated up-stream of the main valve 2 falls. .In this case, at the moment when this part of the main conduit 1.is subjected to pressure, the valve 2 is opened and the pressure intakes 13a and 13b come into action immediately creating pressure in the chamber 9e .which, with the aid of the said spring, suffices to keep the valve 2 open. When the action of the said intakes 13a and 13b ceases, the force of the said spring, which is now the only force, is insufficient to oppose the closing of the valve2 under the effect of the liquid pressure for a normal flow. The valve 2 thus closes automatically and'only reopens when the pressure has dropped sufficiently. This arrangement also enables the receptacle to be emptied through the filling orifice.

In most of the examples described in the parent application, the jet 12 and the tube 13 are arranged in an enclosed chamber 11c. The existence of the said chamber, although recommended, is not necessary, particularly in the case in which the jet 12 and the tube 13 are liable to be flooded by the liquid located within the receptacle which is to be filled, as shown in Figure 6 of the parent application.

The device shown in Figure 2 differs from that shown in Figure 5 of said application Serial No. 319,985 more particularly by the following points:

(a) The end of the chamber 11c which accommodates the member 13 is open instead of closed;

gb) .The press-button 5 of Figure 5 is replaced by a,

member a controlled by a lever 5 similar to the lever of the nozzles shown in Figures 1 to 4 of the parent application; v "-(c)The shaft 7 is rigidly secured to the valve 20;

(d) The conduit 9 which is closed as 'in Figure'S by the two auxiliary valves 20 and 20a, is also closed in certain positions up-stream of the said va lves 20land 20a by a third auxiliary valve 20b which is subjected to the action of a spring; 7 V

(e) A ball 24a is located in a cavity 24 which opens into the chamber 11c and is so inclined that in the positions corresponding to normal use of the nozzle the ball 24 remains in the cavity 24a and emerges therefrom in all other positions;

(f) A plug 25a consisting of a readily fusible material seals a conduit 25 which-connects the chamber 90 to the exterior; V

The operation of this latter type of nozzle is as follows:

In order to fill a tank, the end of the hose-cock is inserted into the said'tank until the orifice 17 islocated at the stop level which is to cause the cessation of the filling. After the operator'has set-the supply .pump in operation, he presses on the lever 5 against the spring 16. This has as'its immediate effect the removal ofthe valve from its seating. The valve 20a then opens, despite the action of the spring 10, because of the pressure prevailing in that part of the conduit 1 which is situated up-stream of the valve 2, the valve 20b remaining off its seat. Under these conditions, the up-stream pressure is transmitted to the face 9d of the piston. Under. the influence of the various pressures acting on the assembly consisting of the valve 2 and the piston 9, the valve '2 opens until the valve 20 isoVertaken' by the shoulder of the conduit 9 said shoulder forming the seat of the valve 20. The conduit 9] is then. againclosed. Two cases may occur:

First case.The flow through the by-pass 11 is insuflicien-t toensure in the intake 13 a pressure whichis of itself sutficient to keep the valve 2 open. In this case, as soon as the conduit 91 is closed, the valve 2 tends to be closed until it reaches a position slightly less open than the position corresponding to closing of the conduit 9 by the valve 20. Thus it is possible to regulate as desired the quantity of the flow by displacing the lever 5 more or less, but it must be pointed out that the closing of the hose-cock is no longer automatic and depends on the will of the operator.

Second case.The flow in the by-pass 11 is suflicient to ensure a pressure in the intake 13 suflicient to maintain the valve 2 open. In this case, the liquid flows away through the slot 11a in the by-pass 11 and emerges from the jet 12 in the form of a stream which strikes the pressure intake 13 as in the case of Figure 5 of said application Serial No. 319,985. As described with referenceto that figure, the valve 2 also tends to a large opening but is prevented therefrom in this case by the valve 20 which forms a stop. The instant at which the valve 20 serves as a stop depends on the state of compression of the spring 16, which depends on the wish of the operator. Thus the latter can, by means of the lever 5, regulate the extent to which the spring 16 is compressed and so regulate the degree of opening of the valve 2.- When the opening of the latter is sufliciently large, the valve 20b closes the inlet up-stream of the-conduit 9 this latter action not causing any inconvenience since the pressure of the intake 13 on the face 9d is suflicient to maintain the valve 2 in its open position. When the liquid in the tank reaches the orifice 17, the air no longer arrives by the conduit 19 and the orifice 18. The stream of liquid issuing from the nozzle 12 fans out immediately after egress from the said nozzle and loses speed. The pressure drops and possibly disappears altogether-in the intake 13. The pressure on the face 9d therefore falls. The resultant pressure acting on the valve 2 and piston 9 is then such that the valve 2 closes. Closure of the valve 2 then shuts the by-pass 11 but during this displacement, the valve 20b, the cross-section of which is larger than that of the inlet of the conduit 9 stays forced on its seat by the liquid pressure on its up -stream side, despite the return action of the spring 4b, which neutralises the effect of the opening'of the said conduit 9 by the valve consequence of the descending movement of the piston 9, the lever 5 still being supposed to be held in one of its opening positions. After the closure of the valve 'Z'du'e to the pressure drop in the intake 13, if' the operator completely releases the lever 5, the pressures on the two faces of the valve 2% are equalised as a result of the presence of a slot forming by-pass in the disc of said valve and the valve 2% is dislodged by the action of the spring 4b. The apparatus can then function again.

If the operator does not. release the lever, the valve 20 remains open and impedes the balance between the pressures on the two faces ofthe valve20b. The .la'tte'r thus remains seated and preventsifurtherflowr p If, bymistake, theoperator dropsthe hos'e-cock-while it is pouring, the said hose-cock;cannot be :kept balanced in a normal jpouring position, since the ball 24a. emerges from its cavity 24- byits own v weight and locates itself in the trajectory of the stream issuing from the member-12, whence there results a disturbance in the chamberll'c and premature closing of the valve 2.

.If a fire breaks out inthe vicinity. of the hose-cock the temperature rises and ends by melting the plug 25a, so that the pressure in the chamber 9 is relieved through the conduit 25 and the flow stops. I I claim: V I
