| description | REVERSIBLE AIR-OPERATED PERCUSSIVE ACTION MACHINE FOR DRIVING HOLES IN THE GROUND A reversible air-operated percussive action machine for driving holes in the ground has a housing accommodating a hammer capable of reciprocating therein. An air distributor is arranged in the hammer in the form of a fixed tube and a valving member movable relative to the tube. Defined between the tube and valving member is an accumulating chamber provided with a means for communicating it with an air reeding line. An air restricting means is further provided for discharging air from the accumulating chamber when the supply of compressed air to the air feeding line is terminated. The valving member is spring-load-ed relative to the tube by a spring means arranged to that during feeding compressed air to the accumulating chamber the valving member is acted upon by a pressure force directed counter to the action of the spring means. |
