Abstract

1340017 Rock drills ATLAS COPCO AB 19 April 1971 [19 Feb 1970] 22146/71 Heading B3C [Also in Division B4] An hydraulic rotary percussion rock drill comprises a housing 10, a piston 12 for producing the percussive action on the drill 19, first and second pressure chambers 25, 34, a fluid pressure distribution valve 42 connected to the chambers 25, 34 by respective first and second passages 50, 51, and a pressure accumulator device 32 connected to the first chamber 25, the valve 42 being shiftable under control of the piston movement alternately to pressurize the first passage 50 and drain the second 51, and vice versa. The drill 19 is rotated by an hydraulic motor 20 geared to a sleeve 17, which sleeve is drivingly co-operable with a splined drill shank 18.
