1. A faucet comprising:
- (A) a valve body having a bore that has axially aligned inlet and outlet ports and having a seat disposed adjacent said outlet port;
(B) a shank to which the valve body is connected, said shank having an inlet, an outlet opening into said inlet of said valve body, and an interior passage having at least a downstream portion that terminates at said outlet of said shank and that is radially aligned with and that opens into said inlet port of said valve body;
(C) a plunger disposed in said valve body between said inlet port and said outlet port, wherein said plunger has an upstream end and a downstream, free end, and wherein said plunger is moveable axially within said bore, in a direction parallel to fluid flow, from a valve-open position to a valve-closed position, an extension being located on said upstream end of said plunger and having a free upstream end that forms said free end of said plunger and that extends into said downstream portion of said passage in said shank when said plunger is in both said valve-open position and said valve-closed position; and
(D) a valve seal mounted on said plunger, wherein said seal seals against said seat when said plunger is in said valve-closed position and is spaced from said seat when said plunger is in said valve-open position, and wherein at least a majority of said plunger is configured to be immersed in fluid in said bore when said plunger is in said valve closed position.

Abstract
A faucet comprises a valve body having a bore, an inlet port and an outlet port. A plunger is disposed in the valve body and is reciprocated in the bore. The inlet port opens into a fluid passage adapted for connection to a pressurized source, and the outlet port opens into a dispensing spigot adapted to discharge materials from the faucet. A handle having a pivotal lever is disposed in the valve body and engages the plunger to reciprocate longitudinally through the bore. A plug is mounted on the plunger and has axial and radial sealing surfaces. The plug is forced against the axial valve seat when the valve is closed to deform in both axial and radial directions.

12. A faucet comprising:
-
(A) a valve body having a bore that has axially aligned inlet and outlet ports and having a seat disposed adjacent said outlet port; (B) a plunger disposed in said valve body between said inlet port and said outlet port, wherein said plunger has an upstream end and a downstream, free end, and wherein said plunger is moveable axially within said bore, in a direction parallel to fluid flow, from a valve-open position to a valve-closed position; (C) a valve seal mounted on said plunger, wherein said seal seals against said seat when said plunger is in said valve-closed position and is spaced from said seat when said plunger is in said valve-open position, and wherein at least a majority of said plunger is configured to be immersed in fluid in said bore when said plunger is in said valve closed position; and (D) a flow-modifying tip disposed on said downstream end of said plunger, said tip extending at least partially into said outlet port when said plunger is in said valve-open position, and wherein said flow modifying tip has a larger diameter at its upstream end and a smaller diameter at its downstream end. - View Dependent Claims (13, 14, 15)

16. A faucet comprising:
-
(A) a valve body having a fluid source connection portion containing an inlet and an integral downward turning spigot connection portion containing an outlet; (B) a shank to which said valve body is connected, said shank having an inlet, an outlet opening into said inlet of said valve body, and an interior passage having a downstream portion that terminates at said outlet of said shank and that is radially aligned with and that opens into said inlet port of said valve body, said downstream portion tapering radially outwardly toward a downstream end thereof; (C) a horizontally-oriented bore within said body, wherein an inlet port is formed from an upstream end of said bore and an outlet port is formed from a downstream end of said bore, and wherein said inlet port and said outlet port are axially aligned with one another; (D) a plunger disposed within said valve body between said inlet and outlet ports, said plunger having an upstream end and a downstream end, wherein said plunger is moveable axially within said bore, in a direction parallel to fluid flow, from a valve-open position to a valve-closed position, and wherein at least a majority of said plunger is configured to be immersed in fluid in said bore when said plunger is in said valve closed position, an extension being located on said upstream end of said plunger and extending into said downstream portion of said passage in said shank when said plunger is in both said valve-open position and said valve-closed position, said extension being of reduced diameter when compared to that of at least a central portion of said valve body and having a free upstream end, said extension tapering radially inwardly toward said upstream end thereof at in a manner that at least generally matches the taper of said downstream portion of said passage in said shank; (E) a flow modifying tip that is disposed on said downstream end of said plunger that extends at least partially into said outlet port when said plunger is in said valve-open position; (F) a valve seal disposed on said plunger in the vicinity of said downstream end thereof; and (G) a valve seat between said inlet and outlet ports, wherein said valve seal seals against said seat when said plunger is in said valve-closed position and is spaced from said seat when said plunger is in said valve-open position. - View Dependent Claims (17, 18)
