Abstract
A casing bore (29) running parallel to a valve center longitudinal axis (5), with cross bores is furnished at a second longitudinal side of a multifunction multiport slider valve with a valve casing, with a sealed connector plane (3) furnished at a first longitudinal side (2) for supply lines, control lines, user lines and ventilation lines, and with a corresponding support plate. In order to increase the number of functions performed by the multiport slider valve and to easily adjust said slider valve, the casing bore (29) is subdivided into two longitudinal sections (29a, 29b) with individual cross bores (30). Turnable and displaceable sealing discs (32), furnished with openings (33), are disposed in front of the joined ports (31) of the cross bore (30), and cross channels (36), and connected to the pressure line (P), the control line (Z, X), the ventilation lines (R or S) are led starting from the longitudinal side (2) into the two separate longitudinal sections (29a, 29b) of the casing fore (29). The individual cross channels (36) are set in each case to the respective opening or closing function by way of a single-piece floor seal (4).
