<p>1,063,660. Valves. INTERNATIONAL STANDARD ELECTRIC CORPORATION. Jan. 1, 1965, No. 274/65. Divided out of 1,063,658. Heading F2V. [Also in Division G3] The subject matter of this Specification is similar to that described in Specification 1,063,658 but the initial expansion of the rod 69 seats the tube 70 against the ball 74; further rod expansion opens a valve 98 to allow a pilot flow from the inlet 77 to the outlet 107 by channels 92, 106, the latter containing a manually-adjustable plug-valve 108. Still further expansion of the rod 69 unseats the ball 74 to vent the chamber 78. An adjustable stop 110 is associated with the valve 98.</p> |
