Abstract
1337369 Valves COMMERCIAL SHEARING & STAMPING CO 25 Feb 1972 [20 May 1971] 8810/72 Heading F2V Each of a number of control sections arranged in a bank between inlet and outlet manifolds has a groove 30 on each abutment face to convey leakage fluid from supply ports 36, 37 to exhaust ports 28, 29, the various ports being surrounded by an 0-ring 38 intersecting the groove 30. The supply ports connect via inclined passages 34, 35 with chambers 24, 25 connectible alternately to work ports 26, 27 via passages 22a, 22b and 23a, 23b in spool 21, the non-pressurized work port being connected to exhaust at 28 or 29.
