Definitions

• Electromagnetically controlled filling spout Electromagnetically controlled filling spout.
• the present invention relates to an electromagnetically controlled filling spout.
• a filling spout comprising a tubular body in which are mounted a valve extending opposite a valve seat and a magnetic actuating element associated with a coil. external to the tubular body and connected to the valve by an axial coupling member.
• the assembly thus formed is radially rigid so that to ensure precise positioning of the valve relative to the valve seat so as to achieve a satisfactory seal, it is not only necessary that the valve is guided precisely coaxially to the valve seat but also that the magnetic actuating element is guided very precisely coaxially with the valve, which results in very significant manufacturing constraints.
• valve and the magnetic actuating element must be mounted in a rigorously coaxial manner with one another and when the body of the filling spout is formed from several assembled elements, it is necessary that the body elements are mounted relative to each other in a rigorously coaxial manner.
• a first object of the invention is to provide a filling spout that works satisfactorily while being less expensive to manufacture than previous filling spouts.
• a second object of the invention is to propose a filling spout which can be easily adapted to different products.
• a filling spout of the aforementioned type in which the member coupling comprises two elements coupled in a connection comprising a radial clearance.
• the control function exerted by the magnetic actuating element is thus dissociated from the shutter function performed by the valve so that the different elements making up the filling spout can be produced separately and assembled in an arrangement in which they do not are not strictly coaxial without affecting the operation of the filling spout.
• the valve and the magnetic actuating element are mounted in separate body elements connected by a quick coupling member, and the coupling elements are separable. It is thus possible to quickly realize different combinations of the control member and the shutter member.
• one of the elements of the body ' is a coupling bracket C and the other member is a pin compor- as a head engaged between the branches of the stirrup. After opening of the quick coupling member, it is thus possible to dissociate the valve and the magnetic actuating element by a simple lateral offset of the latter relative to each other.
• the filling spout comprises a secondary shutter disposed downstream of the valve and rigidly connected to it, and the body of the filling spout has a restriction opposite the secondary shutter, l secondary shutter and the restriction having suitable dimensions and positioning so that when the valve is closed the secondary shutter has with the restriction facing a clearance just sufficient to retain by capillarity a liquid contained in the body between the valve and secondary shutter. Without risking interfering with the closing action of the valve, a quantity of product is thus maintained in the filling spout sufficient to avoid a defect in the formation of the jet of product when the valve is opened.
• FIG. 1 is a view in axial section of a filling spout according to the invention in a closed position of the valve
• FIG. 2 is a view similar to that of FIG. 1 in an open position of the valve
• FIG. 3 is a partial sectional view similar to that of FIG. 1 illustrating a variant of the outlet member of the filling spout
• FIG. 4 is a partial sectional view similar to that of FIG. 1 illustrating another variant of the outlet member of the filling spout
• FIG. 5 is a front view of an alternative embodiment of the valve
• FIG. 6 is an axial sectional view of an alternative embodiment of the magnetic actuating element.
• the filling spout according to the invention comprises a tubular body 1 comprising three body elements 1.1, 1.2 and 1.3 connected together by quick coupling members 2 and respectively containing the elements ensuring the functions control, shutter and outlet nozzle or secondary shutter of the filling spout according to the invention.
• the control function is provided by a magnetic actuating element 3 mounted to slide in the body element 1.1.
• the magnetic actuating element 3 comprises a solid magnetic core 4 provided at its periphery with guide fins 5 which ensure precise guidance of the core 4 inside the body element 1.1 while allowing the flow of a product between the core 4 and the internal face of the body element 1.1.
• the body element 1.1 is made of non-magnetic material, and is surrounded by a coil 6 connected by a supply wire 9 to supply means not shown to form an electromagnetic actuation device.
• the coil 6 is also surrounded by rings made of magnetic material 7 framing a ring 8 forming a permanent magnet, for example a ferrite ring whose permanent magnetization field extends in an axial direction of the coil 6.
• a ferrite ring whose permanent magnetization field extends in an axial direction of the coil 6.
• the coil 6 is further covered by plates of magnetic material 10 whose periphery is in contact with the rings 7.
• the ferrite ring 8 is preferably dimensioned to exert on the actuating element magnetic 3 a force almost equal to the weight of this element and the equipment associated with it, so that a very low current in the coil is enough to cause a displacement of the magnetic actuating element 3.
• the body element 1.2 contains a valve 11 associated with a guide rod 12 comprising guide fins 13 mounted to slide in a cylindrical bore 14 of the body element 1.2. At its upper part, the bore 14 comprises a chamfer 15 forming a seat for the valve 11 (see FIG. 2).
• the valve 11 has a hub 16 on which is mounted an O-ring. as 17. In the embodiment of FIGS. 1 and 2, the hub 16 has a length greater than the diameter of the O-ring 17 so that the O-ring 17 is mounted on the hub 16 with an axial clearance allowing the seal 17 to slide on the hub, allowing efficient cleaning of the valve.
• the coupling member comprises a C-shaped bracket 19 connected to the magnetic actuation member 3 by a connecting rod 20.
• the branches of the caliper 19 surround a pin 21 comprising a rod 22 fixed to the valve 11 and a head 23 engaged in the caliper 19.
• the rod 22 and the head 23 are mounted in the caliper with a radial clearance so that the precise sliding of the magnetic actuating member 3 in the body element 1.1 and the precise sliding of the valve 11 in the body element 1.2 are not affected even if the body elements 1.1 and 1.2 are not rigorously coaxial.
• the body element 1.3 contains a secondary shutter 24 which is fixed, for example by screwing, to the lower end of the guide rod 12 of the valve.
• the secondary shutter 24 comprises an elongated conical lower part 25 extending opposite a conical restriction 26 of the body element 1.3.
• the secondary shutter 24 is mounted at the lower end of the guide rod 12 of the valve, the latter not being equipped of the O-ring 17.
• the hub 16 of the valve is then engaged in the body element 1.2 until the hub 16 protrudes and the seal 17 is put in place.
• the body element 1.3 is fixed to the body element 1.2.
• the magnetic actuating member 3 is engaged in the body element 1.1 then the assembly comprising the valve 11 is presented first of all in an offset manner opposite the body element 1.1 to bring the head 23 to the level of the opening of the caliper 19 then the body element 1.2 is brought coaxially to the body element 1.1 to engage the head 23 between the branches of the caliper 19.
• the body elements 1.1 and 1.2 are then assembled by means of the quick coupler 2.
• the O-ring 17 bears on the seat 15 and the secondary shutter 25 extends near the restriction 26 in the body element 1.3.
• the dimensions and the relative positioning of the conical part and of the restriction 26 are provided so that in the closed position of the valve as illustrated, the conical part 25 of the secondary shutter is spaced from the restriction 26 with just enough play to retain the product contained in body elements 1.2 and 1.3 by capillary action.
• the magnetic actuating element 3 is offset downward relative to the coil 6, the bracket 19 bearing on the head 23 of the pin 21. For the opening of the valve, the coil is supplied and the element magnetic actuation 3 is driven upward as illustrated in Figure 2. In this position, the valve 11 is open and the secondary shutter 24 is in a position allowing a flow of the product.
• the elongated part 25 of the secondary shutter 24 achieves with the restriction 26 of the element body 1.3 a passage which maintains the flow of the product according to a laminar regime.
• Such a secondary shutter is useful for packaging product which tends to foam during turbulent flow such as milk.
• FIG. 3 illustrates an alternative embodiment in which the secondary shutter has been removed and the body element 1.3 contains only anti-foam grids 27.
• This embodiment can be used in particular for water conditioning.
• FIG. 4 illustrates another alternative embodiment in which the secondary shutter 28 has a low height, which makes it possible to reduce the size of the assembly obtained when it is not necessary to ensure a laminar flow of the product. at the outlet of the spout.
• FIG. 5 illustrates an alternative embodiment of the valve in which the hub 16 is provided with a skirt 29 in which notches 30 are produced, which makes it possible to obtain a more gradual evolution of the flow during opening or closing the valve.
