Working principle
Open the oil gun,then the pressurized oil will open the main valve(Fig 1.),the oil flows into container through body and the pipe. At the same time the high speed oil runs through the umbrella main valve(Fig 1.)and produces the minus air pressure.The air flows through the diaphragm up(Fig 2.)to the vacuum chamber,safely cut off the upper hole(Fig 3.)and then the air goes through the separate channel of the oil pipe(Fig 4.),and enters in order to keep the pressure balance.The oil gun works block normally.If the oil is full and the oil level will block the air flow mouth and make the vacuum produce the minus pressure to move the diaphragm upwards;the tie-bar will lose balance with the effect of the spring to close the main valve.At last,the self-sealing process is completed.
