Abstract

740,238. Manually-actuated valves. FOXBORO CO. Oct. 27, 1953 [Nov. 15, 1952], No. 4157/55. Divided out of 740,179. Drawings to Specification. Class 135. A flow iestrictor for an elastic fluid comprises a pin co-operating with a passage having the same amount of taper as the pin, the larger end of the latter engaging a cap which is connected by a tension spring to a point in the casing of the restrictor near the passage, and the member actuating the pin engages the smaller end of the latter and is adjustably mounted in the casing. The invention is described with reference to the disclosure in Specification 740,179.
