Lynn A. Dietrich - Chambersburg PA
Assignee:
Walter Kidde & Company, Inc. - Clifton NJ
International Classification:
F16K 2900
US Classification:
137312
Abstract:
A manually operable hydraulic selector valve includes a plurality of two-way spool valves which are normally closed and are selectively shiftable individually or in pairs by a joy stick operator to open positions whereby motive fluid can be delivered to a given instrumentality such as the jack cylinder of a construction crane outrigger arm. The joy stick carries a conical disc which cammingly engages drive pin extensions of the individual spool valves. A positive stop for the conical disc is afforded by contact of the disc with the mounting plate of the selector valve. The selector valve is employed with an associated two-way directional control valve.
