ABSTRACT:
An adjustable flow restricting valve for speed control of a pneumatic motor, comprising a tube shaped valve body which is rotatably supported in a boring and which is provided with a recess for uncovering fully or partly an outlet opening in the boring. The restricting valve is associated with a control valve for operation of a pneumatic motor. The tube shaped valve body is rotatable by means of a maneuver screw which extends transversely relative to the valve body and which forms a worm gear with the latter. The high gear ratio of the worm gear enables a precise setting of the valve body. In a multiple arrangement of control valves, the tubular valve body of one flow restricting valve forms part of the exhaust passage from one or more flow restricting valves, located upstream thereof.
