Abstract

A valve assembly has a valve housing formed with a bore open at a surface and extending along an axis, an inlet passage opening into the bore, inner and outer outlet passages also opening into the bore, and an inner valve seat between the inlet passage and the inner outlet passage. A sleeve fitted in the bore forms an outer valve seat between the inlet passage and the outer outlet passage and a valve body is displaceable in the bore between an inner position against the inner seat and blocking flow from the inlet passage to the inner outlet passage and an outer position against the outer seat and blocking flow from the inlet passage to the outer outlet passage. A retaining disk fitted in the bore between the outer surface and the sleeve secures the sleeve in the bore. A stem extending through the sleeve and through the disk has an inner end connected to the valve body and an outer end outside the valve housing. Seals are provided between the sleeve and the stem.
