Water softening apparatus |
| abstract |
An improved resin tank for a water softening apparatus including an expansible chamber 50 that enlarges during fluid flow through the tank to displace any free space in the tank, thereby maintaining the compactness of the water softening material. The expansible chamber 50 is formed by an elastomeric sleeve 52 that is secured to and surrounds a portion of a downwardly extending fluid conduit 46 and overlies at least one aperture 54 formed in the conduit wall through which fluid communication is established. The pressure drop normally occurring during fluid flow through the tank generates a pressure differential force on the sleeve wall 52a that causes it to enlarge if free space in the tank is present. In an alternate embodiment, the fluid communication between the conduit and the chamber 50 is provided by a pitot tube 62 that is disposed in the conduit fluid flow path and is operative to communicate the velocity pressure of the fluid flowing down the conduit 46 to the chamber 50. |
