込機の操作弁構造。 This driving machine drives fasteners using compressed gas supplied into the accumulator as power, and is equipped with a main valve and a sub-valve that can be operated from the outside.The main valve is connected to the accumulator, and the sub-valve is connected to the main valve. In a driving machine having a structure in which the width valve communicates with the drive valve and the driving machine moves when both the main valve and the sub-valve are open, the sub-valve has a valve seat at its upper end. A valve body is located below the valve body and is slidably fitted inside the valve cylinder and seals gas by contacting the valve seat at the bottom dead center position. It has a plunger that can be operated from above, and a spring B provided between the valve body and the plunger.The spring load of the spring B at the top dead center position of the plunger is equal to The load is set to be smaller than the downward pressing force caused by the pressure, and the upper part of the valve body has a contact surface A, and the contact surface B that contacts the contact surface A when the valve body moves upward is the valve body. The operating valve structure of the driving machine is characterized by being installed indoors.
