A rotor of a dynamoelectric radial flux machine and a dynamoelectric machine having such a rotor are provided. In order to design the rotor to be as efficient and cost-effective as possible, it includes a laminated rotor core with individual laminations stacked axially one above the other. Axially extending and circumferentially distributed cooling ducts and substantially radially extending inflow ducts are arranged within the laminated rotor core. The individual laminations have the same lamination cross-section, the laminated rotor core is formed in a staggered manner from laminated core sub-units that are rotated relative to one another, and each individual lamination includes cooling-duct holes and inflow-duct holes. The inflow-duct holes in the individual laminations of a first laminated core sub-unit axially overlap with the cooling-duct holes in the individual laminations of the remaining laminated core sub-units for forming the axially extending cooling ducts.

Cooled rotor of an electric machine

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.

Cylinder-piston unit

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.
