<p>PCT No. PCT/US87/00542 Sec. 371 Date Dec. 22, 1988 Sec. 102(e) Date Dec. 22, 1988 PCT Filed Mar. 16, 1987 PCT Pub. No. WO88/07151 PCT Pub. Date Sep. 22, 1988.A mixing valve includes a faucet body (1), a control mechanism, a support surface (9a) for a fixed valve plate (18) mounted on this support surface, a seal (16, 17) placed between the fixed plate and the support surface and a movable valve plate (19) connected to the control mechanism and appointed to shift in sliding contact with the fixed plate so as to regulate the flow rate and the mixing proportions. An attachment mechanism (31) connects the fixed plate to the support surface, the seal being compressed between them, by these parts exerting a compressive force. The compression of the seal is therefore made independent of the pressure between the fixed and the movable plates which can then be reduced to render better sliding and working of the valve plates. The attachment mechanism can be fixed or removable, and can work near the center of the fixed plate or along its border or in both positions.</p> |
