Retaining device for an electric motor

A fan wheel has a cup shaped hub having an outer cup wall with a plurality of vanes and a cup bottom connectable with a shaft of a drive and provided at its inner side with a plurality of ribs defining a plurality of fields therebetween. The cup bottom in the region of the fields has a plurality of depressions extending from its inner side and having a width approximately 70% of a thickness of the cup bottom.

A device for heating a passenger space in a power vehicle comprises a main passage for supplying air, an intermediate passage associated with the main passage and branching into side passages connected with a passenger space, a heat exchanger, a branching passage leading from the main passage over the heat exchanger, a guiding element movable between and fixable in at least two end positions for air to connect the branching passage with the main passage and to separate the former from the latter so that in a flow direction of the air the air enters behind the heat exchanger in the intermediate passage, a blowing nozzle opening in a passenger space and connected with the intermediate passage, the intermediate passage being subdivided in partial passages, one of the partial passages being connected with the blowing nozzle while the other of the partial passages merging into the side passages, the guiding element in its operative position in which it connects the branching passage with the main passage opens a channel to one of the partial passages and blocks the other of the partial passages.

An air conditioning device has a control member, an electric motor arranged to be operatively connected with the control member and drive the latter, an actuating element arranged to sense air temperature and to actuate the electric motor, an interrupting element for interrupting the connection between the electric motor and the control member, and a manual adjustment member arranged for manually adjusting the control member upon interruption of the connection between the electric motor and the control member.

A radial blower, preferably for blowing air through a heat exchanger or air conditioner in a motor vehicle, mainly comprises an impeller wheel preferably directly driven by an electric motor, wherein the driven impeller wheel is mounted in a housing, the peripheral wall of which spirally approaches the outer periphery of the impeller wheel and passes at the outlet of the housing over in a so-called tongue delimiting the outlet at one side, in which the shortest distance between the outer periphery of the impeller wheel and the peripheral housing wall is located downstream of the tip of the tongue, as considered in the direction of rotation of the impeller wheel. The tip of the tongue is formed by a sector of a circular cylinder and the housing has between the region of the shortest distance of the housing wall from the circumference of the impeller wheel a planar wall portion which is tangential to the spirally formed portion of the housing and the sector of the circular cylinder forming the tip of the tongue.

A pump housing accommodates in it an output shaft of an electromotor which forms a unit with the pump, and a rotor having substantially slots is mounted on the output shaft for rotation. The slots accommodate sliding vanes. A mounting member mounts the rotor on the output shaft in such a manner that the motor can tilt to a limited extent about two axes which are normal to each other and to the longitudinal axis of the output shaft of the electromotor.
