    摘要: A protective apparatus for preventing the infiltration of contaminants in a fluid-operated percussion device, having a striking tool (3) that is guided to move in a housing (2) and is driven by a percussion piston in the striking direction (arrow 1), and a seal (7) that is supported at least indirectly on the housing (2), on the one hand, and on the striking tool (3), on the other hand, and has a securing segment that is fixedly disposed with respect to either the housing or the striking tool. The seal (7) is disposed between the inner guide portion (5b) of the striking-tool guide and the theoretical striking plane (4) of the percussive piston on the striking tool (3), when seen in the direction opposite the striking direction (arrow 1), such that the countersurface (3e) for the seal, which countersurface moves relative to the securing segment (7a) of the seal (7) and is in contact with the seal, is unaffected by wear.

    摘要: A fluid-activated, percussive impact tool has a piston therein that reciprocates longitudinally but not rotationally. The piston activates a wrap spring clutch to rotate the drill steel. A removable splined nut in combination with the tool's housing restrains rotation of the piston, while permitting longitudinal reciprocation of the piston.

    摘要: A pneumatic rock drill which has a pneumatic percussion unit with a piston which slidably engages the cylinder in which it reciprocates. Preferably clearances of less than less than about 0.00125 inches per inch of piston diameter and greater than about 0.00075 inches where clearances are diameter are maintained to assure a fluid film between the piston and the cylinder wall. The clearances are based on diameters. The piston of the pneumatic drill has at least one stem section which slidably engages a distributor.The rock drill has a pneumatic motor connected to the percussion unit and engages a distributor of the percussion unit. A air motor gear in the pneumatic motor is rotatably mounted on the distributor.The exhaust is employed to lubricate the bearings and gearing which turn the striker bar.
