ABSTRACT:
An adjusting device is proposed for controlling flowthrough cross sections of a line carrying operating medium in internal combustion engines. The throttle device which varies the flowthrough cross section is disposed, together with the electromechanical actuating member thereof, within a tubular housing and surrounded by an annular chamber. The dispensed operating medium flows from one connecting pipe to the other connecting pipe of the adjusting device through the annular chamber. In this manner, an adjusting device is created which can be built into hose-type lines in a linear fashion; the electromechanical actuating member, for instance an adjusting magnet, is necessarily cooled by the surrounding flow of the operating medium to be dispensed. Furthermore, a body having the form of a helical spring serves as a throttle device of the adjusting device. When it is compressed, this body, together with a flexible element, interrupts the communication between the annular chamber and the adjacent line.
