Patent ID: 11731255

Abstract:
This driving tool includes: a pressure accumulator (26) in which a compressible gas is accumulated; a striking part which operates in a first direction to strike a fastener with a pressure of the compressible gas; and a driving part which causes the striking part to operate in a second direction opposite to the first direction and to increase the pressure of the pressure accumulator (26). The driving tool further includes: a cylinder chamber (98) in which the compressible gas to be supplied to the pressure accumulator (26) can be contained; a holder (44) forming the pressure accumulator (26) and the cylinder chamber (98); a piston (97) which is disposed in the holder (44) and is operable to reduce the volume of the cylinder chamber (98); and a switching valve (92) capable of connecting and disconnecting the cylinder chamber (98) and the pressure accumulator (26).
