Title: Metering and cutoff devices for fluids
IPC: G05D7/00
Filed: 1964-07-03
Abstract: 1,040,646. Dispensing fuel. D O V E R CORPORATION. July 3, 1964 [July 11, 1963], No. 27535/64. Heading A4T. A metering and cut-off device, which may be used with a petrol dispensing nozzle, Fig. 1, contains an hydraulic motor 20 driven by the passage of fluid between portions 2 and 3, and a valve 18 operated by a cam follower 52 in contact with a cam 45, which is driven by the motor 20 through speed reduction gearing 31-38. The cam 45 has a notch 53 to allow the cam follower 52 to close the valve when a predetermined amount of fluid has passed through the metering and cut-off device. The quantity of fluid to be dispensed is adjusted by depressing a knob 41 to disengage gears 38 and 37, and setting a pointer on the knob 41 against an appropriate mark on a dial 42, which movement simultaneously rotates shaft 40 and cam 45. The gear wheel 38 may have a toothless circumferential section 62 which when orientated adjacent wheel 37 causes the cam follower 52 to open valve 18 but renders the metering and cut-off device inoperative to allow the fluid to be dispensed manually using the dispensing nozzle. The metering and cut-off device may be set to cut off when the amount of fluid dispensed is slightly less than that desired and the extra amount is delivered manually. To prevent the valve 18 being opened while the main nozzle valve is open and causing an uncontrolled flow of fluid, a double poppeted valve 18 is used and the cam 45 is formed with a steeply inclined surface 57 making it difficult to rotate the knob 41 and shaft 40 unless the main valve is closed and the fluid pressures on both sides of valve 18 are substantially equal. The dispensing nozzle may have a venturi device 74 which closes a main valve in the nozzle when fluid outside reaches this point. The operating handle 70 may be held open by a latch 72.
