Abstract

A fluid manifold in the form of an elongated conduit having spaced along its length a plurality of bores extending through a portion of the conduit spaced from the passageway of the conduit and substantially perpendicular thereto. Additional bores extending through the conduit and the passageway of the conduit and valve means for each of the bores to form a plurality of groups of outlets from the conduit with valves for each of the groups.

Claims

1. A fluid manifold comprising a length of pipe having a longitudinal passageway therethrough, a series of bores extending transversely through said pipe and forming outlets from said manifold, a second series of bores extending transversely through said pipe and connecting said first bores with said longitudinal passageway, valve means associated with each bore of said second series, each such valve means comprising a valve member Reciprocally movable to close the corresponding bore, and seated at the inner end of such bore, each valve means further comprising a valve stem having a portion of relatively small diameter adjacent the valve member and a portion of larger diameter remote therefrom, said stems extending transversely across the longitudinal passageway, with the junctures between the two portions of different diameter lying within the said passageway, so that fluid in said passageway will act on the inner ends of said portions of larger diameter to urge the valve members away from their seats, a third series of transverse openings in the pipe, said openings lying opposite corresponding openings of said second series, and each such opening closely and slidably receiving the larger portion of a valve stem, and means engageable with each of said valve means for moving its valve stem toward closed position against the pressure of fluid in said longitudinal passageway.

2. A manifold as in claim 1 wherein each valve stem additionally includes a second portion of relatively small diameter at the end of the stem remote from the valve and the means for moving the valves toward closed position act upon said last-mentioned portions.

3. A manifold as in claim 2 wherein a plate is mounted on the outside of the pipe adjacent each valve stem and includes a tubular extension through which the small outer portion of the valve stem passes, and wherein a cap is threadedly engaged with said extension, said cap covering the outer end of the valve stem and adapted to engage it to move the valve to closed position or to allow it to open to a predetermined extent under the pressure of the fluid in the longitudinal passageway.

4. A manifold as in claim 1 wherein the bores of the first series extend transversely through the pipe below the longitudinal passageway and open outwardly of the manifold at each of their ends, and wherein the passages of the second series open into the mid portions of the corresponding passages of the second series.

5. A manifold as in claim 4 wherein the valve members seat downwardly on the inner ends of the passages of the second series, so that they will close by gravity and prevent leakage when fluid pressure in the manifold is shut off.
