Abstract
In a mixing valve having a stationary ceramic disc 22 and a movable control disc 20, a control shaft 5 is arranged in a radial through bore 46 in a guide part 43 rotatably mounted in a housing 32. A control pin 15 is inserted through a central bore in the control shaft, and its spherical lower end engages a socket 17 of a connecting piece 18 rigid with the control disc. Sleeves 7 having flanged outer ends configured for the attachment of an operating yoke 3 are mounted on both ends of the control shaft by means of mating axial serrations. The position of the yoke can be adjusted by varying the position of the sleeves. Only one rotating element is employed whose bearing parts are not subject to wear since only very small rotary angles are necessary, and the rotary force is transmitted from the yoke to such element over the entire length of the control shaft.
