うになした空気工具における正逆転切換バルブ。 A switching valve device is provided in a part of the air supply path that leads to the air motor, and the valve device is connected to a bushing with holes that connect to the air supply path and exhaust path on the air motor side and the main valve side, and a spring pressure inside the bushing. The switching valve is slidably inserted into the switching valve, and the switching valve has two independent inner chambers for forward/reverse switching and a pneumatic chamber for resetting formed on the outer periphery of the switching valve. A passage formed in the switching valve and a small hole conduct the switching valve, and the switching valve in the pushed-in state is maintained at the pressure in the air chamber, and when the air supply is stopped, the internal pressure in the air pressure chamber decreases. A forward/reverse switching valve for air tools that automatically returns.
