Abstract

1,240,038. Valves. BLACK CLAWSON CO. 20 Jan., 1969 [18 Jan., 1968], No. 3224/69. Heading F2V. [Also in Division G3] A balanced bi-directional differential pressure responsive control valve forming part of an automatic pneumatic control system for a paper pulp refiner (see Divisions G2-G3) comprises a cylindrical housing 80 containing an air inlet port 65, outlet ports 82a, 82b for connection to an air motor in the control system and exhaust ports 86, 87. The housing is fitted with a hardened steel ported metering sleeve 90 whose ports communicate with passageways formed in a hardened steel spool 92, which slides in the sleeve 90 to a position determined by a control spring 100 and by the air pressure at inlets 115, 116 in the extremities of the housing. Normally, the spool 92 is maintained in a central position where its central lands 95 block the inlet port 65 and its passageways 96a, 96b respectively uncover a portion of the exhaust ports 86, 87, causing the outlet ports 82a, 82b to be vented to manifold. Variation of the pressure at inlet 116 causes movement of the spool 92 to the left or right with consequent variation of the connections of the inlet, outlet and exhaust ports, which variation restores the pressure at inlet 116 and returns the spool 92 to its central position.
