Abstract

A water valve control assembly comprises two permanent magnets 3 and 4, a piston 8 and a water vessel 1 in which a first permanent magnet 3 causes a rising magnetic field thereby interacting on a second permanent magnet 4 to cause the piston 8 to control a water valve 10.

Description

1 2443908 The present invention is concerned with the control of water

valves and in particular the control of water valves by a piston activated by the magnetic force of a second resiliently mounted permanent magnet under the influence of a moving magnetic field created by a first permanent magnet situated in or on a water holding vessel.

Embodiments of the invention's use will now be described by example only and with reference to the accompanying drawings in which:- Fig I Shows a two permanent magnet water valve control assembly in a bath tub or sink overflow control situation using the reservoir means of EU Patent No 1250495 to house the first permanent magnet which is embedded in a float whilst the second permanent magnet is resiliently mounted on a piston adjacent to a water valve. Fig 2

Shows a two magnet water valve control assembly in an irrigation control situation using a water vessel mounted directly below plants in a tray or pot with the first permanent magnet mounted to a flexible area of the water vessel whilst the second permanent magnet is resiliently mounted on a piston adjacent to a water valve. Fig 3

Shows a two permanent magnet water valve control assembly in a further irrigation control situation using a water vessel mounted directly below plants in a tray or pot with the first permanent magnet mounted on slideably and resiliently in the mouth of a sub section of the water vessel.

In operation as a bathtub or sink overflow flood control assembly the invention oould act in the following manner:-Water flowing into the reservoir I from a bathtub or sink (not shown) would rise in the vessel causing the float 2 and the magnet 3 embedded in it to move upward thereby causing the magnetic field created by the permanent magnet to, at some point, cause action at a distance on the permanent magnet 4 resiliently mounted by a spring 5 on the piston 8. Because the poles of the permanent magnets are, in this example, are like and facing each other the resulting action will be to be a movement of the piston because the float would be held by a stopper 9, causing the piston to enter the valve aperture 10 resulting in the pressure on the valve's diaphragm 11 thereby shutting down the water flow into the bathtub or sink (not shown). On the drain off the spring will cause the piston to return to the starting position.

In operation as an irrigation water flow control assembly the invention could act in the following manner:-Water coming from a water source (not shown) via the valve 6 and flowing into the water vessel 7 via pipe way P1 would begin to fill this vessel and by force cause the flexible area 12 on which is mounted permanent magnet 13 to move in the direction of the arrowhead causing the magnetic field created by this magnet to cause an action, at a distance, on the permanent magnet 14 which has, in this example, like poles resulting in the piston 8 on which the magnet is resiliently mounted by springs to move into the valve aperture 10 resulting in pressure on the valve diaphragm 11 thereby shutting down the water flow into the irrigation vessel. When the plants cause evaporation of the water in the irrigation vessel the bulge on its side will recede causing the situation to reverse resulting in further water flow into the irrigation vessel.

In a second irrigation embodiment, Fig 3, the water vessel is constructed with an extended portion 16 to its upper part. The first permanent magnet 17 is slideably and resiliently mounted in the mouth of the extended area. When water rises to this height the force of the water will cause the magnet to slide into this extended area causing the magnetic field to act upon the permanent magnet 18 mounted on the piston 8 which has resilient means resulting in the piston entering the valve aperture and by pressure on the valve's diaphragm 11 cause a shutdown of the water supply to the irrigation vessel. On evaporation by the plants the water in the vessel's extension would recede allowing the resilient means to return the magnet to the starting position.

Claims

Claim I An assembly of permanent magnets wherein a first permanent

magnet is carried in or on a water vessel and where a second permanent magnet mounted remotely on a piston which controls a water valve by magnetic force on the piston activated by water flow into the water vessel or by loss of water from the vessel.

Claim 2 A water vessel according to Claim I, which is either flexible or solid.
