A fill valve for controlling liquid level in a toilet tank or other tank includes a housing with an inlet, an outlet, a valve, and a level sensing mechanism for opening the valve to permit flow when the liquid level is below a predetermined value. A flow impedance path including a compact array of many baffles defining multiple consecutive right angle turns dissipates fluid pressure without substantial velocity increases and consequent cavitation and noise. Stable valve closure when the predeter...

A fill assembly for a cooling tower comprising a plurality of fill strips positioned within the fill area, a plurality of spaced apart vertically suspended fill hangers positioned transversely with respect to said fill strips within said fill area, said fill hangers having a plurality of substantially horizontally and generally vertically extending members which intersect one another to form a plurality of parallelogram grids, each of said fill strips being supported by a horizontal portion of o...

A fill valve, or aspirator, which is adapted to be connected to a superatmospheric pressure source, such as helium, and which is capable of intermixing at least two fluids in intimate fashion, wherein in one embodiment, actuation of a slide-like member allows introduction of a second fluid, for example, ambient atmosphere, so that ambient atmosphere is drawn into the fill valve by reason of a venturi effect due to the interior configuration of the fill valve so that an air and helium mixture may...

A fill device for filling a system, via a fill pipe thereof, with a liquid to a selected fill level, which device includes a housing, a rod axially displaceably mounted in the housing with one end of the rod forming a liquid outlet opening arranged to extend into the fill pipe to the selected level, a flow control unit connected between the outlet opening and connections for liquid supply and extraction lines and operable to connect a selected one of those lines to the outlet opening, a clamping...

An elongated pouring spout is provided incorporating relatively rotatable inner and outer tubular members which are longitudinally shiftable and relatively rotatable relative to each other. The spout includes inlet and outlet ends and the outlet end of the outer tubular member is closed by an end wall and includes a plurality of peripherally spaced and radially outwardly opening ports formed therein adjacent the end wall. The outlet end of the inner tubular member is open and includes a beveled ...

A fill valve assembly for a water tank such as a toilet tank. The fill valve assembly includes a head portion containing a valve mounted on top of a vertical water outlet tube and a float which moves vertically along the outlet tube to control the opening and closing of the valve. The float is vertically adjustable without removal or disassembly of the valve assembly in order to adjust the tank water level to a preselected position. The float includes an inverted cup-shaped structure which moves...

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...
