초록

A valve operator having a piston or diaphragm and connected polygonal piston rod which supplies reciprocable motion to a key or follower which acts within a spiraled slot formed in a coupling member attached to a valve gate to rotate the valve gate to a desired angular position. One embodiment includes means to bias the piston and the valve gate in a desired angular position from closed to open or therebetween.

대표
청구항

A valve having a valve body with a fluid passageway therethrough and a valve gate member rotatably positioned in said passageway, said gate member adaptable to close said passageway and to open said passageway when rotated to a different angular position, a stem member to which said gate member is supported and rotatably connected, an operator arranged to rotate said stem member and thereby said valve gate member, said valve operator comprising, in combination: a tubular operator housing supported at one end thereof on said valve body with the tubular ax...
