Abstract

1306927 Valves BROOM & WADE Ltd 16 March 1970 [17 March 1969] 13910/69 Heading F2V [Also in Division F1] A manually operated control valve assembly for controlling the supply of compressed air to a reversible rotary motor 13 (see Division F1) comprises a cylindrical spool 32 slidably mounted within a sleeve 5 itself slidably mounted in a bore 31, both spool 32 and sleeve 5 being urged to the left as shown, in the off position by compressed air admitted via inlet 1 to the bore 31. The sleeve thus uncovers a port 43 to admit air to a chamber 4 of a relay valve 39 to bias its spool 7 to the left against a spring 8, whilst a sealing head 36 on the end of the spool 32 seats on the end of the sleeve 5 to prevent air reaching the motor via port 10, passage 11 and spool 7. Initial manual pressure on a trigger 6 on the end of the spool 32 lifts the head 46 off the sleeve 5, thus admitting air to the motor which exhausts into chamber 15. Further pressure on the trigger 6 moves the spool 32 and sleeve 5 together relative to the bore 31, the sleeve now connecting port 43 to atmosphere via port 18 and passages 19, 20 and 21 thus allowing spring 8 to move spool 7 to the right to reverse the admission and exhaust connections to the motor so reversing its rotation.
