Definitions

  • the invention relates to a device for dispensing liquid fuels from a storage tank by means of a nozzle provided with a fuel nozzle and gas nozzle, to which the fuel is supplied by a fuel pump arranged in the lower part of a fuel pump with the interposition of a measuring unit with a pulse generator for determining the amount of fuel flowing through, and which Extraction of the gas escaping during fuel delivery is provided with a gas recirculation channel which is connected to a gas line opening into the storage tank, in which a gas pump is arranged which can be driven by a hydraulic motor which in turn is driven by the fuel delivered by the fuel pump.
  • Such devices for dispensing liquid fuels from a storage tank are known from DE-PS 36 13 453.
  • this known device is used as a hydraulic motor, e.g. drives the gas pump via a gear transmission, uses the measuring unit, which in turn is driven by the fuel delivered by the fuel pump in the manner of a liquid motor. This ensures that the amount of gas extracted is proportional to the amount of fuel dispensed.
  • the invention has for its object to develop a device for dispensing liquid fuels of the type described in such a way that with little technical effort and without intervention in the sealed parts of the pump, existing pumps can be easily retrofitted.
  • the solution to this problem by the invention is characterized in that the hydraulic motor and the gas pump are formed as vane units in a common housing and with a common shaft and between the fuel pump and the measuring unit outside the verifiable and sealed parts of the fuel pump, which essentially consist of the measuring unit , the pulse generator, a calculator and display devices for the amount and price of the fuel dispensed are arranged.
  • both the hydraulic motor and the gas pump as vane units in a common housing and with a common shaft results in a compact unit that can be retrofitted even in the limited space of existing dispensers. Since the installation of the hydraulic motor takes place according to the invention between the fuel pump and the measuring unit, no parts of the gas pump that are subject to calibration and lead sealing are touched, so that re-calibration of the gas pump is not necessary either in the case of subsequent installation or in later maintenance and repair work.
  • the speed of the common shaft of the hydraulic motor and gas pump can be monitored for the purpose of comparison with the pulses received by the computer of the pulse generator driven by the measuring unit.
  • the device shown in Fig. 1 is used to dispense liquid fuels from a storage tank 1, which is normally underground.
  • the fuel in this storage tank 1 is drawn in via a fuel line by means of a fuel pump 3, which is arranged together with a gas separator in a so-called monoblock in the lower part of a fuel dispenser 4.
  • the fuel drawn in by the fuel pump 3 from the storage tank 1 is fed to a measuring unit 5, which is usually designed as a piston knife and is provided with a pulse generator 6.
  • This pulse generator 6 generates a number of pulses corresponding to the flow rate determined by the measuring unit 5, which are forwarded via a pulse line 7 to a computer 8 which determines the output quantity determined by the measuring unit 5 and the associated price of the fuel, and display devices 9 Display of delivery quantity and associated price controls.
  • the fuel emerging from the measuring unit 5 passes through an adapter 10 into a fuel nozzle 11, at the end of which a fuel nozzle 12 with a gas suction nozzle 12a is arranged for filling the respective fuel tank.
  • the device In order to prevent the fuel containing volatile constituents from being released and the gas displaced by the liquid when filling the fuel tank from escaping into the atmosphere, the device is provided with a gas recirculation into the storage tank 1.
  • This gas return comprises a gas return duct 13 running in the dispensing hose 11, which is preferably formed by the dispensing hose 11 consisting of two coaxial running hoses, one medium, for example the fuel, flowing in the outer hose and the inner hose being designed as a gas return duct 13.
  • a gas line 14 is connected to this return duct 13, which leads into the storage tank 1.
  • a gas pump 15 is arranged in the gas line 14, which is driven by a hydraulic motor 16, which in turn is in the fuel line 2 is arranged between the fuel pump 3 and the measuring unit 5.
  • the gas pump 15 and the hydraulic motor 16 are designed as vane cell units which are arranged in a common housing 17.
  • This cylindrical housing 17 is closed at the end by a housing cover 18, which is sealed off from the housing 17 by means of seals 19.
  • a shaft 21 is mounted in the housing covers 18 via roller bearings 20, on which two cellular wheels 22 are fastened by means of a wedge 23.
  • Pallets 24 are slidably guided in radial slots of these cellular wheels 22. These pallets 24 interact with an eccentric bore of an intermediate housing 25 surrounding the respective cellular wheel 22.
  • the connection piece 27 for the inflow and outflow of both the gas pump 15 and the hydraulic motor 16 are - as is apparent in particular from FIG. 5 - formed in the respective housing cover 18.
  • the vane cell unit shown in FIGS. 2 to 5, which forms the gas pump 15 and the hydraulic motor 16 driving this gas pump 15, is installed as a compact unit in the fuel line 2 between the fuel pump 3 and the measuring unit 5, as is shown in the schematic representation of FIG. 1 can be seen.
  • the gas pump 15 and the hydraulic motor 16 are shown as individual units for better understanding.
  • the gas line 14 is connected to the gas pump 15 with the installation of a flame arrester 28.
