Abstract

1407307 Hydraulic control of machine slides COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL 21 May 1973 [23 May 1972] 24206/73 Heading F1P When a pilot valve 58, Fig. 2, is in the position shown, fluid passes through a line 28 and moves a spool 3 to the right by forcing a plunger 34, Fig. 1 against a stop 36. This permits pressurized fluid to pass from a chamber 12, Fig. 2, into a line 21 and a chamber 57 of an hydraulic ram 42, thus moving the body of the ram to the right. When an adjustable stop 45 on the body of the cam abuts a member 47 the spool 3 is pulled back to its central position by links 48, 51, 38. The spool 3 is held centralized by a combination of the action of the mechanical linkage to the ram and the pressure of fluid in the control duct 28. With the pilot valve 58 in the opposite position to the one shown the spool 3 and ram body move to the left. Adjustable throttles 59, 60, 62 control the speed of movement of the ram body. A push-button by-pass valve 63 allows rapid movement when desired.
