Abstract: A device for a flow control of a liquid or gaseous medium, in particular for metering a fluid to be admixed into an exhaust gas treatment system, contains an electromagnet which has a solenoid coil with a magnetic core and an end-side magnetic plate in a magnet housing, and actuates a valve element in a valve compartment of a valve body to control a valve seat located there. The solenoid coil is protected against deformation with respect to the valve compartment, and is sealed using a sealing device.

Abstract: A plug for connection of an electro-fluidic converter provided with electrical plug contacts projecting from a converter housing, the plug has a plug housing, electrical counter contacts to the plug contacts of the converter and accommodated in the plug housing, electrical connecting means for a multi-wired encased connecting cable and accommodated in the plug housing, connecting means for electrical or electronic joining of the connecting means with the counter contacts and accommodated in the plug housing, and a contacting device provided for connecting the connecting cable with the connecting means and arranged in the plug housing, the contacting device having a movable cable receiving part for insertion of a cable portion and a clamping lever acting on the cable receiving part for contact-producing pressing of the cable portion against the connecting means.
