Instead of using mercury to provide a valving action at C, it is possible to use a glass float valve.

It utilizes a float valve to duplicate the reservoir water capacity.

The previous practice of taking a "silencing tube" from the float valve to under the water level is no longer acceptable.

Also sell cartridges, taps, float valves, and other products.

Cold water cisterns, where the float valve outlet must be above the overflow water level.

They also described the use of other valves, including a plug valve, float valve and tap.

The water level in the pan is controlled by a float valve, similar to a small toilet tank float.

Steam engines also use float valves and pressure release valves as mechanical regulation devices.

The snort mast had a float valve that would close automatically if the submarine dropped below periscope depth.

In the head of the snorkel was a float valve which, on dipping, automatically shut in the sea's motion and opened again in air.

Float valve type

Float Shoes and Collars (float valves) prevent backflow after the cement has been pumped into place.

Although not the original inventor, Crapper popularized the siphon system for emptying the tank, replacing the earlier floating valve system which was prone to leaks.

When the combined level drops below 630 litres a float valve opens, allowing fuel from the 122-litre tip tanks to transfer to the front one under bleed-air pressure.

Note that the float valve of a carburetor (controlling the fuel level within the carburetor) is not a needle valve, although it is commonly described as one.

1778: Joseph Bramah invented a hinged valve or 'crank valve' that sealed the bottom of the bowl, and a float valve system for the flush tank.

"The valves are so simple-one floating valve and one flap valve-that all we have to do is spray the valves and valve seats with plastic rubber.

Invennovator Goals: To produce gravity and pressure water filters for domestic use, ornamental vases, and accessories for water filters such as taps, float valves and cartridges.

However, exposure to mercury (used in mercury diffusion pumps and float valves) caused Stock to develop mercury poisoning, which he documented in the first scientific papers on the subject.

This causes one-way clearing valves to stick in the open or closed position, and float valves to leak water due to a failure of the valve seat to seal out water.

When the water drops below a certain level, a pressure switch, level switch or float valve will activate a pump or open a public water line to refill the water tower.

A more recent theory put forward by a few experts is that the snort mast dropped below the surface and the float valve (described above) jammed or somehow failed to stop the water entering the sub.

Whenever the solution is depleted below a certain level, either water or fresh nutrient solution is added, A Mariotte's bottle, or a float valve, can be used to automatically maintain the solution level.

A ballcock (also balltap or float valve) is a mechanism or machine for filling water tanks, such as those found in flush toilets, while avoiding overflow and (in the event of low water pressure) backflow.

If either the sump clearing valve sticks open or the top float valve sticks closed, a snorkel is rendered useless as a breathing aid and the swimmer is forced to fall back on alternative surface breathing methods.
