摘要： A plunger is shiftable in response to a trigger operation by a user. A valve piston has a valve piston chamber therein for slidably accommodating the plunger and an axial bore into which the plunger is inserted. An air passage connects the valve piston chamber to an atmosphere via a clearance between the plunger and the axial bore of the valve piston. A seal member is provided to seal the clearance between the plunger and the axial bore of the valve piston. And, a relief passage is formed on at least one of the plunger and the axial bore of the valve piston to open the air passage, thereby allowing compressed air to exit from the valve piston chamber to the atmosphere under a condition where the plunger is engaged with the axial bore of the valve piston.

摘要： A percussion tool comprises a cylinder 3 communicated to a pressure accumulating chamber 16 storing pressurized air therein, and a piston 4 slidable in the cylinder 3 when pressurized air is introduced into the cylinder 3 from the pressure accumulating chamber 16 and pressure of the introduced air is applied on the piston 4. A circular groove 6 is recessed on a peripheral surface of the piston 4, the peripheral surface adjacently facing to an inside wall of the cylinder 3. A piston ring 10 is accommodated in the circular groove 6, so as to provide a hermetical sealing between the piston 4 and the cylinder 3. And, a ring bumper 11 made of resilient member is provided in the circular groove 6 adjacent to the piston ring 10 in a sliding direction of the piston 4.

摘要： A rigid member is configured to move a valve member to separate the valve member from an engaging part when a push lever moves from a lower dead center to an upper dead center. A resilient member is configured to move the valve member to separate the valve member from the engaging part when the push lever moves from the lower dead center to the upper dead center. A switching part selects one of the rigid member and the resilient member to move the valve member to separate the valve member from the engaging part. When the switching part selects the rigid member, a fastener driving operation is performed regardless of an order of a pulling operation and a pressing operation. When the switching part selects the resilient member, the fastener driving operation is performed only when the pulling operation is executed after the pressing operation is executed.
