<p>The device has pistons (K1, K2) selectively connected with coupling elements (36, 37) that are attached with valve disks. Pressure transmission paths (29, 30) are guided into a drive device housing (16) at chambers (31-33) defined by the pistons, where one of the pistons is guided in a sealed manner and separated from the other piston in the housing. Sealing areas of the pistons define the chambers, and one of the paths for a cleaning cycle of a valve disk (7) is laterally guided transverse to a common axis (X) of the device housing and a valve housing (1) and directly guided into one chamber.</p> |
