Appl. No.:

10/803238

Inventors:

Daniel A. Klein - Middleton WI, US

Assignee:

Clack Corporation - Windsor WI

International Classification:

F16K 24/04

US Classification:

137216, 137801

Abstract:

A faucet includes a base and a body. The body may be coupled and decoupled to the base with a bayonet fitting which is configured to prevent a forward rotation of the base relative to the body and to permit backward rotation and disconnection of the body from the base without the use of any tools. The faucet may have an internal chamber that houses a water sensitive device such as an electronics package and that is sealed from within and without by a system of seals located between the body and the base, between the base and a support surface, such as a countertop or a sink, and between individual components of the faucet.

Abstract:

Mineral contaminants are removed from water in a system in which water is sprayed into an air head at the top of a tank through a diffuser and withdrawn through a pick-up tube. A solenoid valve operates to allows air from a compressor to flow into the top of the tank through a shuttle valve which is opened by the air pressure. Simultaneously a drain valve connected to the shuttle valve opens a drain, venting water and air from the tank. The shuttle valve, closed by the solenoid valve, closes the air supply line and connecting the shuttle valve to atmosphere, and pressure within the aeration tank can close the shuttle valve, which causes closing of the drain valve. The part of the valve which opens the drain is made responsive to excess pressure within the air tank to open the drain and so acts as a pressure relief valve.

Abstract:

Contaminants are removed from fluid in a system where the fluid is sprayed into an air head at the top of a tank through a diffuser and withdrawn through a pick-up tube. A solenoid valve operates to allow oxygen-containing gas from a compressed gas source to flow into the tank through a shuttle valve, which is opened by the gas pressure. Simultaneously, a drain valve connected to the shuttle valve opens a drain, venting water and air from the tank. The solenoid valve also operates to close the gas supply line and connect the shuttle valve through a vent to atmosphere. Pressure within the tank closes the shuttle valve, which in turn closes the drain valve and disconnects the shuttle valve from the tank. A one-way-flow valve prevents fluid or gas from flowing from the tank backwards through the shuttle valve to the solenoid valve and out the vent.

International Classification:

F16K 31/18

US Classification:

137413, 137397, 137426

Abstract:

A liquid refill control for a holding tank includes a pneumatic solenoid valve for delivering liquid to the tank in an open state and restricting delivery of the liquid to the tank in a closed state. The solenoid valve has a pneumatic exhaust. A container mounted in the tank includes an inlet for introducing liquid from the tank into the container and an outlet formed below the inlet. A discharge valve is operably mounted to the tank for alternately closing and opening the outlet. A lower float closes the discharge valve when the liquid is at or above a predetermined level in the tank and opens the discharge valve when the liquid is below the predetermined level to discharge liquid from the container. A pneumatic exhaust valve alternately opens and closes the pneumatic exhaust which in turn changes the state of the pneumatic solenoid valve. An upper float mounted in the container maintains the pneumatic exhaust valve in one of the open and closed conditions when the liquid in the container is at or above a threshold level and maintains that valve in the other condition when the liquid in the container is below the threshold level.

International Classification:

Abstract:

A filter assembly is provided for a manifolded water filtration system and includes a filter element, a brine seal located at the top of the filter element and engaging a boss depending from the system manifold. The brine seal isolates a rinse water discharge port, communicating with a an outlet of the filter element, from an untreated water inlet port formed in the boss so as to ensure that the water to be treated passes through the filter membrane as opposed to directly out of the rinse water discharge port. This configuration eliminates the need for an exterior feed line, thus simplifying the system and preventing vibration during system start-up. The brine seal also structurally reenforces the filter element, facilitates assembly of the filter, increases the capacity of the assembly, and reduces the chances of failure and leakage.
