Abstract

446,040. Valves. ULDALL, P., Lallaguda, Deccan, India. April 1, 1935, No. 10104. [Class 135] An automatically closing valve opened by a pump device comprises a piston 13 raised within a sleeve 16 by depressing a handle 3 to open a ball-valve 20 in a partition 17a, drawing up the loosely fitting hollow part a carrying the valve b to allow water to pass from the inlet 4 to the outlet 6. The piston 13 is hollow and the nut 12 securing the rod 10 is perforated ; on the down-stroke a ball-valve 14 in the piston base opens to allow the water beneath it to pass to the upper side, this water passing into the supply channel by ports 27, 26 on the up-stroke.
