Abstract
1386974 Valves HYDRAULIC INDUSTRIES Inc 22Febl972 [2Novl971] 5500/74 Divided out of 1386971 Heading F2V The subject-matter of this Specification is the same as that described in Specification 1,386,971 but the claims relate to the adjustable stop mechanism disposed at one end of the spool. An extension 141 of the spool extends freely through a screw-threaded member 140 adjustably engaged in the body of the valve and has an adjustable nut 148 attached at its end. Adjustment of the nut 148 and the member 140 can determine the limits of movement of the spool in two directions.
