高圧エア貯留室とを備えた空気圧式釘打機において、上
記１次圧と２次圧との圧力比の逆比よりも大きいな作用
圧の受圧有効面積比を有する大面積部と小面積部とを備
えたピストン弁を１法王エア供給側と高圧エア貯留室と
の間に介設し、上記大面積部に１次圧を作用させる一方
、小面積部に２次圧を作用させ、１次圧の供給時には高
圧エア貯留室と大気との連絡を遮断するとともに、上記
１次圧の供給停止により上記高圧エア貯留室を大気に開
放することを特徴とする空気圧式釘打機の安全バルブ。In a pneumatic nailing machine equipped with a booster that boosts the pressure of 1st air supplied from the outside to create high pressure 2nd air, and a high pressure air storage chamber for storing this high pressure air, the above primary pressure and A piston valve having a large area part and a small area part having a pressure receiving effective area ratio of the working pressure which is greater than the inverse ratio of the pressure ratio with the secondary pressure is installed between the air supply side and the high pressure air storage chamber. The primary pressure is applied to the large-area part, while the secondary pressure is applied to the small-area part, and when the primary pressure is supplied, communication between the high-pressure air storage chamber and the atmosphere is cut off, and the A safety valve for a pneumatic nailer, characterized in that the high-pressure air storage chamber is opened to the atmosphere by stopping the supply of primary pressure.
