Abstract

1503842 Valves COMMERCIAL SHEARING Inc 13 Jan 1976 [13 Jan 1975] 01266/76 Heading F2V In a direction control valve for fluid motors with pressure compensating means dependent on a pressure difference, a valve member 12 cooperates with inlet, work and outlet chambers 17, 15, 13 and has an axial chamber 20 containing a spool 102. Movement of the valve member 12 to left or right causes pressure difference between the ends of spool 102 from either work and inlet or work and outlet chambers so that flow via the spool is dependent on #p.
