Apparatus for governing the idling RPM of an internal combustion engine

Servo-drive for rotary angle adjustment of an actuator for controlling

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.
