Abstract

608,780. Valves closing, with rush of fluid. DANIELSON, J. A. Jan. 15, 1946, No. 1394. [Class 135] A cut-off valve, e.g. for incorporating in the compressed air supply line of a pneumatic tool, comprises a ball G, Fig. 1, which normally rests in a curved seating 10 at the inlet end of the lower inclined wall 9 of the casing with a small segment of the ball surface exposed to the inlet opening 1a so that an excessive rate, of air flow, e.g. due to the removal of the tool, forces the ball on to a seating 12 surrounding the outlet opening 7 and cuts-off the supply of air. On replacement of the tool, leakage of air through a byepass 13 controlled by an adjustable grub-screw 14 permits air pressure to build up between the ball and the tool and unseats the ball. Movement of the ball from its normal position uncovers an escape passage 21, and a reed 23 positioned across the outer end of this passage provides an audible warning signal.
