ABSTRACT:
A valve assembly has a fixed disk and a movable disk. The fixed valve disk has a flat face centered on an axis and is formed to one side of the axis with an axially throughgoing aperture. The normally rotary movable valve disk has a flat face bearing on the fixed-disk face and formed to one side of the axis with an axially throughgoing aperture. Thus on rotation of the rotary disk about the axis relative to the fixed disk the apertures are moved between an aligned position in which fluid can pass through the apertures and a nonaligned position in which each disk at least partially blocks the aperture of the other disk. One of the disks is formed at the respective face to the other side of the axis with an inwardly open recess positioned so as to be exposed by the aperture of the other disk in the nonaligned position.
