PRESSURE FLUID DISTRIBUTION CONTROL APPARATUS IN * ESPECIALLY * JET LOOM

摘要

The present invention relates to an apparatus for accurately controlling the distribution of pressure fluid through a number of branch conduits, the apparatus being advantageously employed for jet looms. The apparatus eliminates excessive wear of mutually engaged parts which would otherwise cause unwanted time delays in the operative steps of the system with which it is employed. The apparatus includes a plurality of valves, each valve having a movable valve element coupled with the outer race of an anti-friction bearing mounted on an eccentric by means of a piston and a push rod provided with a spring which maintains the piston in engagement with the outer race. The valve is opened when a stop on the piston is moved by the eccentrics into engagement with the other end of a push rod which forms a part of the movable valve element.
