An apparatus for supplying fluid of predetermined quantity comprises a supplying passage for supplying fluid, an opening and closing valve provided within the supplying passage, mechanism for opening the opening and closing valve, locking mechanism for locking the opening and closing valve in an open state, negative pressure generating mechanism for generating negative pressure upon supply of the fluid outside through the supplying passage, lock releasing mechanism for releasing the lock of the locking mechanism by the introduction of the negative pressure generated by the negative pressure generating mechanism atmosphere introducing mechanism for introducing atmosphere into the lock releasing mechanism to neutralize the negative pressure, solenoid valve for interrupting the atmosphere introduction by the atmosphere introducing mechanism, measuring device for measuring the flow rate of the fluid supplied through the supplying passage, and control signal transmitting device for transmitting and supplying the control signal to the solenoid valve when the measured flow rate of the fluid reaches a predetermined flow srate. The solenoid valve interrupts the atmosphere introduction by the atmosphere introducing mechanism according to the control signal. The lock releasing mechanism closes the opening and closing valve and releases the lock of the locking mechanism by the negative pressure upon interruption of the atmosphere introduction.

Apparatus for supplying fluid of predetermined quantity

A fuel supplying apparatus comprises a fuel supplying nozzle having an ejection pipe for ejecting fuel and a supplying passage for supplying the fuel to the ejection pipe, an opening and closing valve provided in the supply passage, a nozzle lever for opening the opening and closing valve, locking mechanism for locking the opening and closing valve in an open state, negative pressure generating mechanism for generating negative pressure upon supply of the fuel outside through the ejection pipe, lock releasing mechanism for releasing the lock of the locking mechanism by the introduction of the negative pressure generated by the negative pressure generating mechanism, atmosphere introducing mechanism for introducing atmosphere into the lock releasing mechanism to neutralize the negative pressure, solenoid valve for interrupting the introduction of the atmosphere by the atmosphere introducing mechanism when no current is introduced, and allowing the introduction of the atmosphere by the atmosphere introducing mechanism when introduced with current, and detection and current applying switch for detecting the insertion of the ejection pipe inside a fuel intake opening of a vehicle and the like and introduces current to the solenoid valve.
