ABSTRACT:
A valve for fluids exhibits a valve casing (1) with a sealed valve element (2) movable into various switching positions, as well as connections (3) through (6) for operating lines, pressure lines, vent lines, and the like. The valve is furnished with sealing rings (7) forming a valve seat (19) in the individual switching position in each case together with the peripheral faces of the valve casing (1). The valve is of a simplest construction for a large number of switching positions and for different numbers of switching positions with short switching times and with a smallest possible number of parts. At least one sealing ring (7) is coordinated to the rotary-driven valve element (2). The sealing ring (7) is in each case disposed in a plane (9), running at an angle relative to the rotation axis (8). A disk (11) or an axial body are disposed in the same plane (9) defined by the sealing ring. The disk (11) or axial body form the valve seat (19 ) in each case together with a spatially fixed sealing ring (7), or the respective disk (11) or, respectively, the axial body and at least one corresponding sealing ring (7) form the valve seat (19) together with the valve casing bore (1a) in different rotary positions of the valve element.
