Abstract

816,774. Fluid-pressure servomotor-control systems; valves. HEALY, D. V. Aug. 2, 1955, No. 32825/57. Divided out of 816,773. Drawings to Specification. Class 135. The subject-matter of this Specification is included in Specification 816,773 but the claims are concerned with a construction of fluid discharge nozzle associated with the armature which comprises a sleeve extending about and spaced from the nozzle, a cap rigidly secured to the sleeve and a plunger, movable with the armature and passing through the cap for movement with respect to the cap, whereby fluid discharged from the nozzle impinges against the plunger and is directed outwardly into the cap and thence between the sleeve and nozzle to the return conduit.
