Abstract: A valve control device of the kind used in ABS or ASR systems as applied in motor vehicles. Such a valve control device comprises a valve block that accommodates the solenoid valves and where a solenoid is assigned to each solenoid valve. The side of a solenoid holder facing the valve block has compartments for accommodating the solenoids, there being an elastic spring element on its compartment base that presses the solenoid against the valve block. Furthermore, each solenoid has first media that, when the solenoid is introduced into this compartment, act together with second media, assigned to the compartment, as a snap latch in such a way as to prevent the solenoid from being pulled out from this compartment. The first and second media are sufficiently elastic that the solenoid can still be moved slightly in all directions in the plane perpendicular to its coil axis.

Abstract: The invention relates to a housing for installation in motor vehicles to hold electronic components arranged on a PCB. In accordance with the invention, the housing comprises a trough-shaped housing section and a metal lid. In addition, several heat sinks are arranged on the PCB, with the PCB being firmly connected exclusively to these heat sinks. Here, the heat sinks are designed such that they are in direct contact with both the housing section and the metal lid.

Abstract: A propeller for gaseous and fluidic media, particularly an air propeller which is formed with at least one vane mounted to a hub of the propeller and rotatable about a central axis of the propeller. The vane includes two blades extended in the radial direction of the vane. The blades are spaced from each other by an elongated slot formed in the vane and extended in the radial direction of the vane. The slot has the length which is about 40 to 50% of the length of the radius of the vane, defined between the center of rotation of the vane and its tip.
