Abstract: A gas control valve (1) has a central module (40), a control module (20) and a sensor module (30). Gas can flows through the central module (40) from a valve inlet (41) to a valve outlet (42). The control module (20) is directly on the central module (40) and controls a flow of the gas through the central module (40). A throttle element (23) is fluidically arranged between the valve inlet (41) and the valve outlet (42). The sensor module (30) is arranged directly on the central module (40) and has at least one sensor (31, 32) in operative connection with the gas flowing through the central module (40) through a gas inlet (44) fluidically arranged between the throttle element (23) and the valve outlet (42). In order to control the pressure, it detects a pressure difference between the gas flowing through the central module (40) and air having a reference pressure.

Abstract: The invention relates to a rotor (30) of an electric motor having a shaft (33) and a magnet (32) disposed on said shaft (33), wherein the magnet (32) is attached to the shaft (33) using an injection molded plastic material and the plastic material forms a cooling vane (31) which generates a cooling air flow when the rotor (30) is in operation.

Abstract: The invention refers to a connector unit formed out a side piece of a blower housing and an engine mounting plate for a drive motor of a blower, whereby the engine mounting plate is attachable to the side piece in a variety of rotational or alternatively angular positions vis-à-vis a rotational axis that runs in an axial direction to the side piece.

Abstract: The invention relates to a vibration damping receptacle device for receiving a motor (1) on a fan housing wall (2) having a motor support element (3) on which a plurality of attachments (4) are formed, a plurality of receptacles (6) disposed directly on the housing wall, and a plurality of elastic damping elements (5) disposed between the attachments and the receptacles such that the axial center axes thereof are each oriented at least in sections in the direction of the motor.

Abstract: A fan wheel comprises a hub and a plurality of blades extending radially outwardly from the hub. A ring is arranged in coaxial relationship with the hub and radially between the hub and the outside periphery of the fan wheel. The ring has a plurality of defined fixing positions distributed over the periphery thereof for mounting at least one balancing weight.
