AIR GUN CAPABLE OF ENHANCING A SEALING PROPERTY BY MAXIMALLY REDUCING ABRASION RATE DURING REPETITIVE OPERATIONS OF A VALVE ACCORDING TO OPENING AND CLOSING OF COMPR ESSED AIR EXHAUSTION

摘要

PURPOSE: An air gun is provided to maximize output quantity of compressed air by using a unique nozzle structure and to enhance spraying effects by reducing noise due to compressed air spray.;CONSTITUTION: An air gun comprises a nozzle (300), a valve body and an air gun body (100). The air gun body comprises a valve chamber (150) in which an air passage (120) is formed inside and which is connected to the air passage as being crossed; and a pulling lever (110) which is rotatably combined in one side of the valve chamber by using an axis pin (140). The valve body comprises a Teflon seal (220) and a cushion packing (230) installed in one-way direction of the valve chamber in order; a piston (210) which is slidingly elevated by pulling the pulling lever as being penetrated through the Teflon seal and the cushion packing in a closed state; an opening and closing valve (240) which opens the air passage by elevating the piston; a compressed spring (250) which elastically supports one side of the opening and closing valve; and an air-tight cap (260) which seals the other side of the valve chamber by elastically supporting the opening and closing valve by pressing the other side of the compressed spring.;COPYRIGHT KIPO 2013
