Abstract
1354648 Percussive tools ATLAS COPCO AB 18 Sept 1972 [17 Sept 1971] 43209/72 Heading B4C [Also in Division F2] A valve in a pressure fluid actuated tool, e.g. a nut runner, screw driver, grinding machine, blowing nozzle or a chipping hammer as shown, comprises a control valve 15, Fig. 1, formed by a hollow elastomeric element 27 open at one end towards a pressure fluid inlet 25 and deformable by a radial rod 36 or 37 to define an axial flow channel from the inlet to the appropriate outlet channel 28 or 32. Thus the valve can be used as shown to control flow of pressure fluid to the hammer piston 16 of the impact motor via channel 28, chamber 29 and disc valve 17, and also to independently control flow of pressure fluid through channel 32 and exhaust passage 20 to blow away the chippings. The element 27 has a pair of stiffening ribs 42, 43 which may be wire reinforced Fig. 7 (not shown). The element may be of frusto-conical form, Fig.2 (not shown). Projection 35 prevents rotation of the element. After removal of threaded bush 44, the element can be removed by blowing it out with compressed air delivered through passages 20, 47.
