Abstract

A diverter valve has a housing forming an inlet for pressurized fluid and a pair of separate outlets connectable to respective users. A valve disk fixed in the housing is centered on an axis and has to one side of a diameter through the axis two axially throughgoing outlet ports each communicating with a respective one of the outlets and to the other side of the diameter an axially throughgoing inlet port communicating with the inlet. The ports are spaced about the axis and centered on a circle itself centered on the axis. A valve disk sitting on the fixed valve disk is movable in the housing about the axis. This movable valve disk is formed with a pair of axially throughgoing holes spaced about the axis and centered on the circle. A spindle rotatable in the housing about the axis is connected to the movable valve disk for displacing the movable valve disk from a central blocking position in which the holes overlap only the inlet port and between one end position in which one of the holes overlaps one of the outlet ports and the inlet port and permits fluid communication therebetween and another end position in which the other of the holes overlaps the other of the outlet ports and…
