LIQUID SUPPLYING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a liquid supplying apparatus with a simple structure which does not require a solenoid valve and a control wire corresponding to each supply gun. SOLUTION: The liquid supplying apparatus comprises a single or a plurality of sub pipe lines 7 having a supply gun branched from a tip of a main pipe line 6 connected to a liquid supply source 2 and a pressure switch 12 for sensing an internal pressure provided on the main pipe line 6. It further comprises a control means for activating a pump 3 of the supply source to supply liquid and set detection pressure to a specified pressure when the detection pressure of liquid in the main pipe line 6 is lower than the specified pressure.
