Abstract

A fuel supplying apparatus with a remote control preset mechanism which comprises a preset operation part provided at a readily reached position on a fuel supply nozzle or on a hose adjacent to the nozzle and a main preset mechanism provided at a position remote from the preset operation part and effecting presetting by signals transmitted from the preset operation part. The preset operation part and the main preset mechanism are connected by relatively few signal transmitting wires. The preset mechanism emits a valve closing signal when a preset numerical value and a numerical value obtained from signals transmitted by the signal emitting part of the flowmeter, corresponding to the quantity of fuel which has been supplied, coincide with each other. The fuel supplying apparatus stops its supply of fuel in response to the valve closing signal.

Claims

1. A fuel-supplying apparatus with a remote control preset mechanism comprising a structure means extending above a fuelsupplying service area, a fuel reservoir, a fixed conduit having one open end in the fuel reservoir and extending through the structure means, said fixed conduit having a second open end, a movable fuel-supplying conduit having one end connected to said second open end of the fixed conduit and a forward end including a delivery nozzle, said movable fuel-supplying conduit being suspended from the structure means and adapted to be raised upwardly and lowered downwardly, a stop valve provided on the fixed conduit, a flowmeter located in the fixed conduit to measure the quantity of fuel discharged from the nozzle through the fixed conduit and the movable fuel-supplying conduit, said flowmeter including a signal emitting part for emitting signals corresponding to the measured flow quantity, an indicator provided on the structure means and displaying the measured amount of the flowmeter, a preset operation part provided on the movable fuel-supplying conduit at a position such that said preset operation part can be readily operated by an operator supplying the fuel and emitting preset pulse signals corresponding to a desired preset numerical value of the fuel to be supplied, said preset operation part comprising a dial which can be turned through an angle corresponding to the desired numerical value, means for sequentially emitting the preset pulse signals corresponding to the turning angle of said dial, and means for emitting shunt signals at the start and completion of the turning of said dial, preset means provided in the indicator and presetting said desired numerical value by counting the pulse signals transmitted from the preset operation part, and wires extending from the preset operation part to the preset means through the movable fuel-supplying conduit and transmitting the pulse signals emitted by the preset operation part to the preset means, said preset means comprising a counting circuit for counting pulse signals, a register which receives and registers the result of the counting by said counting circuit of the presetting pulse signals transmitted from said pulse signal emitting means of said preset operation part and effects shifting by the shunt signal transmitted from said shunt signal emitting means of said preset operation part thereby presetting said desired numerical value, means for comparing the preset value transmitted from said register and the result of counting by said counting circuit of the pulse signals transmitted from said signal emitting part of the flowmeter and emitting a valve closing signal when the preset value and said result of counting coincide with each other, and means for transferring said valve closing signal to said stop valve as a signal for closing said stop valve.

2. A fuel-supplying apparatus with a remote control preset mechanism comprising a structure means extending above a fuel-supplying service area, a fuel reservoir, a fixed conduit having one open end in the fuel reservoir and extending through the structure means, said fixed conduit having a second open end, a movable fuel-supplying conduit having one end connected to the second open end of the fixed conduit and a forward end including a delivery nozzle, said mOvable fuel-supplying conduit being suspended from the structure means and adapted to be raised upwardly and lowered downwardly, a stop valve provided on the fixed conduit, a flowmeter located in the fixed conduit to measure the quantity of fuel discharged from the nozzle through the fixed conduit and the movable fuel-supplying conduit, said flowmeter including a signal emitting part for emitting signals corresponding to the measured flow quantity, an indicator provided on the structure means and displaying the measured amount of the flow-meter, a preset operation part provided on the movable fuel-supplying conduit at a position such that said preset operation part can be readily operated by an operator supplying the fuel and emitting preset pulse signals corresponding to a desired preset numerical value of the fuel to be supplied, preset means provided in the indicator and presetting said desired numerical value by counting the pulse signals transmitted from the preset operation part, and wires extending from the preset operation part to the preset means through the movable fuel-supplying conduit and transmitting the pulse signals emitted by the present operation part to the preset means, said preset operation part comprising an insertion mechanism, a card having a construction corresponding to a desired preset numerical value adapted for being inserted in said insertion mechanism, a mechanism for discharging said inserted card from said insertion mechanism at a constant speed, a first signal emitting means for emitting by each figure pulses in a number corresponding to the preset numerical value of said card as preset pulse signals in cooperation with the discharging of said card by said card discharging mechanism, and a second signal emitting means for emitting a card insertion completion signal when said card is completely inserted into said insertion mechanism, and said preset means including means for receiving and counting the signals transmitted from the signal emitting part of the flowmeter and sending out a signal for closing the stop valve when the counted value coincides with the preset numerical value.

3. The fuel-supplying apparatus as claimed in claim 2 wherein said preset mechanism comprises a counting circuit for counting pulse signals, a memory circuit for receiving and storing the result of the counting by said counting circuit of the preset pulse signals transmitted by each figure from said first signal emitting means of said preset operation part thereby effecting presetting of said desired numerical value, a switch means provided between said counting circuit and said memory circuit closing by the signal transmitted from said second signal emitting means and opening by a first signal transmitted from said signal emitting part of the flowmeter, means for comparing the preset value transmitted from said memory circuit and the result of counting by said counting circuit of the pulse signals transmitted from said signal emitting part of the flowmeter and emitting a valve closing signal when said preset value and said result of counting coincide with each other and means for transferring said valve closing signal to said stop valve as a signal for closing said stop valve.
