Abstract
A valve for distributing pressure air to remove lint from a knitting machine at locations where it typically accumulates, in which plural balls are normally seated in valve openings to close the flow passages to these locations and are unseated therefrom to allow the flow of pressure air when contacted by a rotating arm. Control over the movement of the ball is exercised by the seating of the ball not only in a horizontally oriented valve opening, but also in an opening of a vertical wall adjacent to the valve opening, so that the two noted horizontal and vertical openings positioned about the ball provide a desired position to the ball, and the projection of the portion of the ball through the vertical opening presents it for unseating contact by the rotating arm.
