| 摘要 |
The invention relates to a device for equalizing the hot water and cold water pressures in a hot water faucet for sanitary use comprising, upstream from a thermostatic unit (200);a moving element (108) constituted by a membrane (109) whose plane determines the plane of symmetry of the chambers and a control rod (110) passing through the membrane (109) at its center, to which rod said membrane is attached,valves (111, 112) mounted on each of the two ends of the common control rod, which cooperate with seats (113, 114),means (115, 116) for translationally guiding the control rod,a nonreturn valve (117, 118) installed in each of the inlets of the chambers.This device is characterized in that the guiding means (115, 116) are located at each of the ends of the control rod and have guiding surfaces smaller than the cross section of the valve and/or the control rod. |
