This application claims priority from India patent application number 201821006240, filed on Feb 19, 2018.
FIELD OF INVENTION
[1] This invention relates to Fueling valves, commonly known as Nozzles, also gun (due to its shape!), which are used for dispensing gasoline and such fluid into transport vehicles. Particularly, this invention relates to providing fuel identification and other information on the fueling valve.

BACKGROUND
[2] With the introduction of multi product dispensers (MPDs), a popular model of fuel dispensers which can dispense more than one variety of fuel from one station, there has been a dire need to have redundant and unambiguous identification of fuel being dispensed into any transport vehicle, lest inappropriate fuel gets dispensed causing irreparable damage to the engine system of the transport vehicle. The problem is graver when person filling fuel in the transport vehicle is not well versed with the multi product dispenser, since there are several manufacturers with their own different models.

[3] There are several attempts to solve this problem. Patent US5184655 discloses a boot having a message display platform supporting a message placard. Patent application US2010/0223826 discloses nozzle display arrangement integrated into the structure of the nozzle guard. Patent application EP3202706A1 discloses a product plate having mounting legs which are reversibly inserted into recesses provided in the counter - clamping surface provided on the dispensing valve. WO9315493A1 also discloses a device for placing information on a filler gun of a fuel pump. Several disclosures pertain to electronic displays, like US5184309, EP2505547A1.

[4] Let us familiarize with another situation when an MPD has a faulty nozzle and spare nozzle of different make is available. In such a situation, identification would be of different type and appearance. At times, the identification may be erroneous. Our invention is an effective and economical solution to address the gap.

OBJECTIVES
[5] The objective is to invent an arrangement for identifying specific fuel which is dispensed by a fuel dispensing valve, or nozzle.

[6] Another objective is to invent an arrangement which can be added at site.

[7] Another objective is to invent an arrangement which displays information in a defined manner.

[8] Another objective is to invent an arrangement which cannot be removed without leaving tempering trace or damage.

[9] Another objective is to invent an arrangement which is cost effective.

[10] Another objective is to invent an arrangement that is suitable for several makes of dispensing valves or nozzles.

SUMMARY OF INVENTION
[11] The present invention is an identification arrangement for fuel dispensing valve, comprising a badge pad, an identification badge and a valve envelope. The identification badge comprises an identification surface on an upper side on which identification information may be printed or disposed. There are provided a plurality of flexible legs on a lower side of the identification badge. The flexible legs have an entrapment channel there between. The entrapment channel is a pathway to accommodate another construction in the badge pad. Each flexible leg comprises a locking foot which further comprises a slope surface and an engaging surface, the slope surface and the engaging surface mating at an acute angle, preferably of value between 45º to 60º. There is provided a kink, which is a reduced cross section zone, near a root of each flexible leg. The badge pad comprises a holding surface, a lower surface, a receptacle having a curvatured edge running between the holding surface and a retaining surface provided on the lower surface. The badge pad further comprises a plurality of peripheral walls and optionally a means to selectively separate one or more of such peripheral walls. The means may be a notch on each peripheral wall wherefrom the peripheral wall can be broken away with the help of a gripping tool. The valve envelope is made of a flexible insulating material, which is generally an engineering thermoplastic. An internal volume of the valve envelope, when moulded, is upto about 10% less than a volume of the valve that is engulfed by the valve envelope. Consequently, the valve envelope is required to be stretch with sufficient manual forces in order that it be slipped on to the valve rather tightly. There is provided a recess and a bridge is carved by suitably removing some material of the valve envelope. The identification arrangement is situated on the valve body cap. The badge pad is axially positioned on the valve body cap such that the badge pad engulfs the valve body cap axially and then the badge pad cannot move in any direction other than a Y direction. The valve envelope is slipped on to the valve and possible movement of the badge pad in the Y direction is then also restricted. The identification badge is then pressed onto the badge though the recess on the valve envelope such that the bridge on the valve envelope is accommodated in the entrapment channel in the identification badge, and such that the slope surface of the boot glidingly interacts with the curvatured edge of the receptacle of the badge pad and the engaging surface of the locking foot is locked with the retaining surface of the badge pad. Any attempt to dislodge the identification pad from the badge pad causes partial or complete rupture of the flexible leg from the kink, rendering the identification badge unusable. The identification badge as per present invention wherein fits on a variety of dispensing valves or nozzles, including Elaflex, Tatsuno, Catlow, Husky and OPW, with or without the badge pad. In order to provide the identification arrangement on any dispensing valve at site, the recess and the bridge may be carved on respective valve envelope by a low-cost tool. As another embodiment, the identification arrangement has the identification badge disposed directly on a valve body cap having an integrated receptacle and an integrated curvatured edge.
