Abstract: A centrifugal fan comprises a rotor that has a rotor yoke, an impeller that has a blade and is coupled to the outer periphery of the rotor yoke, a motor that rotates the rotor and a casing that has a suction opening and a discharge opening, and houses the rotor, the impeller, and the motor. The impeller rotating together with the rotor discharges air sucked in through the suction opening to the outside of the casing through the discharge opening. An inner periphery part of the blade on the rotor yoke side extends to the inner periphery side, in such a manner as to overlap with an outer peripheral surface of the rotor yoke in the axial direction of the motor.

Abstract: A valve device for a cooling water system of a motor vehicle, with a housing including a first connection and a second connection for a first liquid circuit, and a third connection and a fourth connection for a second liquid circuit, wherein the first connection is permanently fluidically connected to the second connection, and with a valve unit including a movably mounted valve element with which a thermally activatable spring element is associated, and which opens a connection between the third connection and the fourth connection in a first end position and cuts off the connection in a second end position. The thermally activatable spring element is arranged in a chamber located between the first connection and the second connection, which is permanently cut off from the third and the fourth connection and which preloads the valve element in the direction of the second end position.
