The disclosure relates to a direct current electric machine comprising a housing, a rotor having coils configured as electromagnets, and a stator with stator magnets. The rotor and the stator are positioned inside the housing. The electric machine also comprises sliding contacts configured to conduct current which is to be conducted through the coils of the rotor, as a commutator. The electric machine further comprises an interference suppressor configured to suppress electrical interference that emanates from the direct current electric machine. The interference suppressor is positioned outside of the housing.

Direct current electric machine

A final control element for a control unit, for a throttle body located in a conduit carrying a gaseous medium in an internal combustion engine, is disclosed which has a control shaft, supporting the control unit in a manner fixed against relative rotation; a power takeoff member of a final control element gear, the power takeoff member being seated on the control shaft in a manner fixed against relative rotation; and an error sensor, detecting the rotary position of the control shaft, with a rotor part that is connected to the control shaft in a manner fixed against relative rotation. The error sensor is a contactless measurement rotary angle sensor, whose rotor part is integrated by material and positive engagement with the drive member. Preferably, the rotor part is made of sheet metal, and the positive engagement is established by spraying the power takeoff member, made of plastic, onto it. The rotor part is welded to the control shaft.

Final control element for a control unit

A device for restoring a rotary member into a defined normal position, with a spatially stationary fixed catch, which predetermines the normal position, and a driver catch, which is coupled to the rotary member and can be moved past the fixed catch, each of which has stop surfaces embodied on each of its opposing sides, and with a clamping spring, which encompasses the catches in a prestressed fashion with two bent spring legs, in order to prevent a rotary play between the clamping spring and the catches in the normal position, and an elastic spring element in at least one leg section of the spring legs extending across the stop surfaces of the catches, which spring element is supported against the associated stop surface with a spring force that is less powerful than the prestressing force of the clamping spring.

Rotating actuator

A method for positionally securing two components together, in which a hollow body is introduced into the two components. Once the final position of the components relative to one another has been established, the hollow body is driven directly into the second component with the application of axial pressure and sonic energy. The method is suitable for employment with thermoplastic components whose relative position to one another is known beforehand, an example being in the assembly of housing parts of a rotary adjuster for controlling a flow cross section in internal combustion engines.

Electromagnetic rotary actuator

An electromagnetic rotating adjuster that has a servomotor with a can-shaped rotor, which is supported by means of a shaft via a first roller bearing and a second roller bearing, in which the disposition of the roller bearings in the one piece housing is inaccessible. For axial fixation of one second roller bearing, a spring washer is disposed in a second bearing opening and the second roller bearing is pressed against it, the outer race of the bearing having a detent groove on its circumference which groove is engaged by resilient detent tongues of a detent ring, supported in an annular groove of the housing. This assures secure fixation of the second roller bearing in the axial direction in a way that both suits the needs of large-scale mass production and is economical. The electromagnetic rotating adjuster may be used in control of the idling air in internal combustion engines. The resilient tongues and washer facilitate removal, as well as installation, of the rotor assembly.

The regulator of this invention is used specifically to regulate the idling speed of an internal combustion engine and includes a servomotor, a throttle unit and a holder designed as separate units and are intended to be combined in an appropriate manner for a particular application. Thus, the throttle unit is provided with a throttle housing incorporating in a cylindrical housing part, a turning space for a throttle member which is connected to a flow channel via an inlet opening and an outlet opening. The flow channel is, for example, built into a wall of an air intake pipe of an internal combustion engine and intersects a receiving opening of this air intake line serving as the holder. The throttle unit is insertable in the receiving opening and is used to control the magnitude of the airflow.
