Pair of hard material plates for a sequential mixing valve
First Claim
1. Control members of a sequential type mixing valve or valve cartridge comprising:
- a pair of hard material plates for insertion into the sequential type mixing valve or valve cartridge,a first of said pair of plates being a fixed plate and a second of said pair of plates being a movable plate contacting said fixed plate and rotatable around a rotation center,said pair of plates arranged to perform, during a control stroke, only a relative rotation around the rotation center,the fixed plate being subdivided by a first straight line passing through the rotation center into a first portion free of any openings and a second portion,the second portion of said fixed plate being opposite the first portion and having two passage openings separated by a rib with a width for sealing at a contact with said movable plate, an area of the two passage openings being just less than an area of the first portion of said fixed plate,said movable plate being subdivided by a second straight line passing through the rotation center into a first portion free of any openings and a second portion,the second portion of said movable plate being opposite the first portion and having at least one passage opening, the at least one passage opening in its whole occupying only a part of the second portion of the movable plate.

Abstract
A pair of hard material plates form the control members for a sequential type mixing valve, the plates perform, during the control stroke, only a relative rotation around a rotation center, the fixed plate has two passage openings and the movable plate has at least one passage opening, the whole of a first portion of the fixed plate is located on one side of a first straight line passing through the rotation center is lacking in openings, both openings of the fixed plate occupy in their whole just less of a second portion of the fixed plate, lying with respect to the first straight line opposite the first portion of the fixed plate, both openings of the fixed plate are mutually separated by a rib having, at least in part, the minimum width needed for ensuring the seal, the whole of a first portion of the movable plate which is located on one side of a second straight line passing through the rotation center is lacking in openings, and the passage openings of the movable plate occupy in their whole only a part of a second portion of the movable plate, lying with respect to the second straight line opposite the first portion of the movable plate.
