Abstract
A mixing valve of the type utilizing a fixed valve seat disk and a movable control disk is described. The axis of rotation of the control disk in the valve housing is offset in relation to the center of the valve seat disk towards the inlet passages. With this arrangement the pivot angle for setting the mixture ratio is increased.
Claims4
A mixing valve comprising:
- a housing having an axis;
- a valve seat disk having inlet water passages and an outlet passage and fixed in said housing so as to be centered on said axis, said passages being spaced around said axis;
- a control disk disposed on said valve disk and having a mixing passage, said control disk being rotatable relative to said valve seat disk to control the mixture ratio and being radially displaceable relative to said valve seat disk to adjust the flow rate, said control disk being rotatable about an axis of rotation parallel to but offset by a predetermined amount from the center of said valve seat disk and said housing axis in the direction of said inlet passages;
- a rotatable member received in said housing and confined to rotation about said axis of rotation;
- and
- means on said member for rotating and radially displacing said control disk.
