(Cl. 251-136) This invention relates to faucets, and particustem l2 which is slidably mounted in a tapered larly to improvements on my faucets for which guide passageway [3 between the chambers.

Where large faucets or valves are used with correspondingly large plungers it is desirable to provide ducts or passageways 23 through the plungersi to facilitate the flow of liquid to fill the I space 25that is created by depression of the plunger. These ducts may be formed relatively large, and various sized bushings or reducing elements 2!? adjustably threaded therein to provide for varying" dimensions to govern theflow of liquid to and fro therethrough. The return or upward movement o-f the plunger, after the rod above is released, is controlled and the time of closing of the valve determined by return or down flow of the accumulated liquid from the spaces 25. g r

The space between the top of the upraised'valve stem and the lower face of the cap, is'wider Y than 'the thickness of the plunger, so that a small 5 I space 21;;for a cushion. of liquid remains above the plunger, when the valve beneath is seated, whereby all noise and vibration is eliminated from the eonnecting pipes or plumbing.

My faucet is specially valuable for preventing loss of water where m'generaluse by the public, when faucets may be left open carelessly. The device may be also adapted for numerous other uses, as for regulated or measured flow when desired, and [or flushoineters or toilet tanks, etc. The valve may be opened by various means (not shown), as by soleno-id or electrical or other mechanical means, or byifioats in water tanks, etc. My faucet is preferably formed entirely of metal,
