A fill valve includes a tubular housing which accommodates a valve member which is biased toward a closed position by a light spring. The valve member includes a head and a tubular portion which is provided with two large windows. When the fill valve is open fluid flows freely through the tubular portion of the fill valve and out of the windows.

A fuel cap assembly for use on fuel tanks on large vehicles such as straight trucks and buses for reducing and preventing fuel fumes and spills from reaching outside of the fuel tank during fuel filling operations. The cap assembly has interior facing threads that wrap about exterior facing threads on the fuel receiving receptacles on the fuel tanks. The cap assembly includes a lid having a normally biased closed door that only opens when a fuel nozzle is pressed into the door. The cap assembly ...

A fill valve has a main valve with a valving surface contacted by a valve disk. A series of offset radial paths separated by a toroidal path permit free radial flow at full open and quiet tortuous flow as the valve closes. Removal of a cap permits access to the main valve for cleaning. Indicia in the valve body provide easy height adjustments. A riser base is made up of easily molded locking parts and provides a variable height adjustment structure that is shielded from view. A flexible cup perf...

A fill valve for controlling the filling of a fluid reservoir such as a cistern. The valve minimizes the time needed to fill the reservoir by maintaining maximum fluid flow through the valve until instantaneous shut off of the fill valve once the reservoir is filled. The fill valve includes a reciprocating valve head carried on a valve stem connected to a float arm for determining the fluid level within the reservoir. The valve head is disposed within an enclosure having grooves for conducting f...

A fill valve (22) for a toilet tank (10) has a probe (44). A cup member (46) is attached to the end of the probe. The cup member (46) has an inner tubular member (72) forming a chamber extension (42b) in communication with upper control chamber section (42a) in probe (44). A check valve (90) is mounted at the bottom end (60) of cup member (46). The cup member (46) provides for adjustability of fill level (41) of the tank by adaptably sliding up or down along the probe (44).
