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.

The plunger is alternatively designed with channels on its exterior and passages through its interior for use with low-viscosity fluids and with a sealing arrangement for use with high-viscosity fluids. The dispensing spigot can be removed to ease access to the plug for cleaning.

Abstract: A valve assembly has (1) a riser pipe including a valve cup housing and portals blockable, and (2) a central tower which communicates with blockable pathways that pass both liquid and gas, and (3) a bi-directional valve member which controls separation of gas and liquid and directional flow in the chamber. A retainer assembly is provided on the outer peripheral surface of the valve cup so as to facilitate insertion of the valve cup into the container but so as to prevent the unintended removal of the valve cup from the container while still permitting selective valve cup removal when it is desired to do so. The retainer assembly preferably includes a protrusion and a pair of centering skids spaced about the outer periphery of the valve cup. The protrusion includes a radially tapered, vertical extending detent portion and a radially tapered, circumferentially extending ramp portion. The centering skids taper radially inwardly from vertically central portions thereof to the vertical end portions thereof.

Abstract: A valve assembly, securable in an upper opening of a container for liquids, is simple and inexpensive to manufacture yet provides improved operability and is capable of relieving excess gas pressure within the container. The valve assembly preferably includes a stub and a riser pipe/valving unit detachably mounted in the stub. The valving unit substantially consists of a unified riser pipe having blockable gas and/or liquid portals, and movable members arranged co-axially within two upper reception areas in the riser pipe and including a single sealing ring and a dispensing tower. The sealing ring is axially displaceable against the pressure of a spring to move from a neutral closed position to a lower open position by way of external activation.
