Abstract

1,062,143. Valves. CATER- PILLAR TRACTOR CO. Aug. 24, 1965 [Sept. 16, 1964], No. 36379/65. Heading F2V. The control of a double-acting jack 14 is effected by valve spool having a centring spring 17, an operating lever 16 and a detent mechanism consisting of a pair of spring-loaded pins 24 that cooperate with an enlargement 25. A piston 26 is slidable in a cylinder in the spool and the cylinder is connected to passages 27, 28. Upon leftward shifting of the spool to direct pump pressure to the rod end of the jack via a pipe 22, the pressure in the latter also communicates with the piston through passages 27, 28. The piston 26 abuts a casing plug, so that when the jack reaches the end of its stroke a sudden pressure rise occurs in pipe 22 which causes the spool to move rightwardly overcoming the detent mechanism and enabling the spring 17 to centre the spool.
