摘要：
An air plunger is described. The air plunger comprises an upper barrel and a lower barrel slidably received by the upper barrel. An air seal is fixed to the lower barrel and slidably engages with the upper barrel. A nozzle is attached to the lower barrel opposite to the upper barrel. A stop mechanism prohibits the upper barrel from disassociating with the lower barrel.
