A dispensing closure (40) for use with a container (44) includes a body (54) having a dispensing spout (72) with an interior surface (80) that defines at least a portion of a passage (132) for communicating with the container interior to permit the flow of a fluent substance through the body (54). The dispensing closure (40) includes a closing element (56) attached to the body (54). The closing element (56) defines a transverse cover (130) having a closed position relative to the body (54) and an actuated, open position relative to the body (54). The transverse cover (130) has an outwardly projecting toggle tab (58) for being engaged by a user to move the transverse cover (130) from the closed position to the actuated, open position. The transverse cover (130) further has a flexible, resilient cantilevered sealing portion (142) that seals against the interior surface (80) of the dispensing spout (72) with the transverse cover (130) located in the closed position.

An air induction system for filtering a compressible fluid to an electromechanical component mounted on a wheel of a vehicle. The system may make use of a first plurality of float valves arranged in series in a non-linear first flowpath path, with at least one of the float valves forming an inlet for intaking the compressible fluid into the first flowpath, and one being in communication with an inlet of the electromechanical component. Each of the float valves may have a buoyant float valve element therein which is responsive to change position when submerged in water, to close off its respective float valve depending on an angular orientation of the wheel, and thus an angular orientation of the float valve.

A stem-guided valve for use inside of a fluid end. The valve body is installed in a conduit that traverses the fluid end housing. A removable guide element is installed within a bore formed in the valve body. A static component that is interposed within the conduit includes an elongate projecting stem. As the stem reciprocates axially with the guide element, the valve is caused to move between open and closed positions. In its closed position, the valve body engages a valve seat that surrounds the conduit. A plurality of perforations are formed in the walls of the guide element, the perforations allow fluid to drain from the guide element during operation.

A pressure-based latching switch includes a shuttle valve, a first valve and a second valve. The shuttle valve may switch a fuel through one of a first port and a second port in response to a greater pressure of the fuel at the ports. The first valve may switch a fuel to the first port while a second pressure of the fuel at the second port is less than a second threshold pressure. The second valve may switch the fuel to the second port while a first pressure of the fuel at the first port is less than a first threshold pressure. The pressure-based latching switch may change the fuel supplied to the fuel cell system automatically from a first fuel tank to a second fuel tank in response to the first pressure of the fuel falling below the first threshold pressure.

A dispensing closure (40) for use with a container (44) includes a body (54) having a dispensing spout (72) with an interior surface (80) that defines at least a portion of a passage (132) for communicating with the container interior to permit the flow of a fluent substance through the body (54). The dispensing closure (40) includes a closing element (56) attached to the body (54). The closing element (56) defines a transverse cover (130) having a closed position relative to the body (54) and an actuated, open position relative to the body (54). The transverse cover (130) has an outwardly projecting toggle tab (58) for being engaged by a user to move the transverse cover (130) from the closed position to the actuated, open position. The transverse cover (130) further has a flexible, resilient cantilevered sealing portion (142) that seals against the interior surface (80) of the dispensing spout (72) with the transverse cover (130) located in the closed position.

A dispensing tap (700) for liquids includes a body (702) connected to the neck of a container (900), a dispensing head (708) with an outlet or mouth (714), and a throat (710) connecting the body to the dispensing head. A shut off valve (716) is configured for sealing engagement with the mouth of the dispensing head, and a piston (718) is axially guided within the dispensing head. The piston includes a peripheral seal (720) slidably engaged with an interior surface of the dispensing head, and a valve stem (722) coupled to the shut off valve. The piston is selectively actuable between a normally closed position an open position. A vent (740) is in communication with an interior of the body and the vent is opened and closed with movement of the piston and shut off valve.
