摘要

1. Multiway valve with one entry and at least two exits and preferably a four-way valve, with a valve casing (4) in which is arranged a rotary valve slide (15) having a packing surface (5), which is formed by a packing member (8) axially displaceably arranged therein and whose back communicates (25) with the interior for compressive load application, the packing surfaces (5) of the outlet ports (6) for the outflowing water being located in the packing or sealing plane of the valve slide (15), the water intake (12) issuing into the valve casing outside the packing surface (5), the valve slide (15) is connected to a rotary shaft (18) arranged vertically to the packing surface and which is led out of the valve casing (4), the interior of valve casing (4) is sealed to the outside (19) and the sealing is performed on the rotary shaft (18) or on a shoulder (17) closely surrounding the same, characterized in that the remaining cross-section of the valve slide (15) is pressure-relieved (20, 21) on the side of the rotary shaft (18), at least one exit (6) is open in each rotation position of valve slide (15), the packing member in the valve slide (15) is a ceramic plate (8), which cooperates (24, 25) in the sealing plane with a ceramic block (7) and the latter is provided at the points of the packing surface (5) not assuming a control function with recesses.
