Abstract: A cylinder-piston unit for actuating a flush valve, comprising a piston which is displaceably mounted in a cylinder and the piston rod of which is operatively connected to a flush valve, and comprising at least one fluid inlet, which opens into the cylinder at or below a lower stop position of the piston, and comprising at least one fluid outlet wherein the piston comprises at least one valve which seals the piston in a lower stop position and opens at least one passage opening in an upper stop position.

Abstract: A combined flushing and filling unit comprising a flush valve and a filling valve, which are situated in an inlet chamber to which line pressure is to be applied, and, between the inlet chamber and a particular outlet line, form a compensation chamber, each of which is closed with the aid of a servo-diaphragm, wherein the inlet chamber communicates with the compensation chambers via a connection opening, in each case, in the servo-diaphragm, and the compensation chambers each have a control opening for generating a pressure decrease, which releases the particular outlet line, in the relevant compensation chamber. Furthermore, a method for the operation of a combined flushing and filling unit comprising a flush valve for triggering an emptying process of a cistern is disclosed.

Abstract: A height-adjustable upright tube-cage unit comprising a telescopic cage which comprises an inner cage and an outer cage, and a telescopic upright tube which comprises an inner upright tube and an outer upright tube and is accommodated in the cage, wherein the elements inner cage, outer cage, inner upright tube, and outer upright tube can be connected to each other via a shared, telescopic scaffolding, wherein the scaffolding is adjustable between a first detent position, in which the inner cage is latched with the outer cage and the inner upright tube is latched with the outer upright tube, wherein the upright tube is longitudinally displaceable within the cage, and a second detent position, in which an upper cage part is latched with an upper upright tube part, and a lower cage part is latched with a lower upright tube part.
