Valved manifold for gauging a plurality of fluid pressures

Claim 1

For use with a pressure gauge, a valved manifold for gauging, selectively and individually, a plurality of sources of fluid pressure, comprising a manifold block having a longitudinal bore terminating in an outlet, the outlet having connector means to attach such a pressure gauge, the manifold block further having a plurality of parallel crossbores extending through the block from a first edge thereof to an opposite edge, each crossbore intersecting the longitudinal bore and comprising a first crossbore portion extending from said first edge of the block to the longitudinal bore, and a second crossbore portion aligned axially with said first crossbore portion and extending from the longitudinal bore to a juncture with an inlet counterbore formed in said opposite edge of the block, each counterbore having means to make an inlet connection from one of said sources of fluid pressures, a valve stem reciprocable within each crossbore and extending through both its first crossbore portion and second crossbore portion and into its counterbore and there having means to seat the stem sealedly at the juncture of the counterbore with said second crossbore portion, each valve stem further having first means to seal between the stem and the first crossbore portion, spring means to bias the stem axially to closed position, and manually depressable means, adjacent to said first edge of the block, to overcome said spring means and to unseat the said means to seat the stem, whereby to provide pressure communication from a selected source of fluid pressure through such inlet connection into the counterbore of one of said second crossbore portions and thence, through said second crossbore portion and longitudinal bore, to such pressure gauge.
