Abstract
Abstract The invention consists of a combination fluid-control-switch valve adapted for monitoring water flow in water-supply systems so as to enable a purification or treatment system therein to operate as the water is being used. The valve comprises a two-section housing, wherein an upper section thereof defines a sealed switch compartment having a switch that is actuated by the movement of a magnet mounted to a pivot arm, and a lower independent section defining a flow chamber having an inlet port and an outlet port, and wherein a poppet valve is located in the flow chamber defined by a slidable valve stem that includes a calibrated washer for setting the flow rate of the water passing through the chamber, a back-flow plate preventing the treated water from becoming contaminated when the system is not in use. Attached to the valve stem is a second magnet that moves up and down with the valve stem and thereby causes the movement of the arm mounted magnet to engage the switch in the switch compartment so as to turn the switch on and off as required.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
215 words
A magnetically controlled fluid-flow-switch valve device, comprising: a housing having an independent upper section and an independent lower section, said upper section defining a switch compartment and said lower section defining a fluid-flow chamber having an inlet port and an outlet port; a switch means positioned in said compartment of said upper section, wherein said switch means includes a first magnet; a one-way valve means located in said fluid-flow chamber of said lower section; a second magnet mounted to said one-way valve means and located within said chamber of said lower section and positioned so as to be juxtaposed with said first magnet disposed in said compartment of said upper section, wherein the movement of said second magnet moves said first magnet to activate said switch means; calibration means adjustably attached to said one-way valve means, whereby the rate of fluid flow passing through said valve means and said chamber is adjustably selected for a given operation therewith; wherein said one-way valve means comprises; a poppet valve having a valve body member defining a valve seat; a valve stem having a valve plate for engagement with said valve seat; and wherein said calibration means is mounted to said valve stem below said valve plate thereof and said second magnet is attached to said valve plate.
Claim 2
Dependent Claim
215 words
A magnetically controlled fluid-flow-switch valve device, comprising: a housing having an independent upper section and an independent lower section, said upper section defining a switch compartment and said lower section defining a fluid-flow chamber having an inlet port and an outlet port; a switch means positioned in said compartment of said upper section, wherein said switch means includes a first magnet; a one-way valve means located in said fluid-flow chamber of said lower section; a second magnet mounted to said one-way valve means and located within said chamber of said lower section and positioned so as to be juxtaposed with said first magnet disposed in said compartment of said upper section, wherein the movement of said second magnet moves said first magnet to activate said switch means; calibration means adjustably attached to said one-way valve means, whereby the rate of fluid flow passing through said valve means and said chamber is adjustably selected for a given operation therewith; wherein said one-way valve means comprises; a poppet valve having a valve body member defining a valve seat; a valve stem having a valve plate for engagement with said valve seat; and wherein said calibration means is mounted to said valve stem below said valve plate thereof and said second magnet is attached to said valve plate.
Claim 3
Dependent Claim
48 words
A fluid-flow-switch valve device as recited in claim 1, wherein said switch means comprises a switch that is adjustably mounted in said compartment and wherein said first magnet thereof is pivotally mounted in a pivot arm having a cam member positioned thereon for actuating engagement with said switch.
Claim 4
Dependent Claim
58 words
A fluid-flow-switch valve device as recited in claim 2, wherein said valve stem is slidably mounted on a valve pin perpendicularly positioned within said valve body, whereby said valve stem and said second magnet move vertically up or down on said valve pin so as to move said second magnet and said cam member with said pivot arm.
Claim 5
Dependent Claim
68 words
A fluid-flow-switch valve device as recited in claim 3, wherein said calibration means comprises a plurality of annular grooves formed in said valve stem below said valve plate and including a calibrated washer adjustably mounted in one of said grooves so as to be moved in and out of said valve body, said washer having a calibrated setting to control the rate of fluid flow through said chamber.
Claim 6
Dependent Claim
22 words
A fluid-flow-switch valve device as recited in claim 4, wherein said switch means includes means for adjusting the position of said switch.
Claim 7
Dependent Claim
64 words
A fluid-flow-switch valve device as recited in claim 5, wherein said switch is secured to said switch-adjusting means which comprises a lever arm having one end pivotally fixed within said compartment of said upper section and an oppositely disposed free end, said free end having a "T" slot formed therein to slidably receive a screw that is threadably attached to said upper section thereof.
