This disclosure relates to a proportional valve arrangement for refrigerants, with a valve housing comprising a valve body chamber, a valve body which is arranged inside the valve body chamber and which is configured to be transferable between a first sealing seat and a second sealing seat. An electrically actuable drive is connected to the valve body via a spindle. A locking device is arranged between the spindle and the valve body and is configured to generate an axial preload between the valve body and the first sealing seat when the valve body abuts against the first sealing seat and for generating an axial preload between the valve body and the second sealing seat when the valve body abuts against the second sealing seat.

Proportional valve assembly for refrigerant

The invention relates to an electromagnetic proportional valve, preferably for refrigerant, which has the following: an armature of an electromagnet which is arranged so as to be able to be moved axially between an idle position, an activation position and working positions and on which an activation element is arranged; a piston which is constructed as a hollow piston and which has at a first axial end region a first opening toward a supply of the expansion valve and at a second axial end region a second opening toward a pressure compensation space; and a blocking member which is constructed to close the second opening, wherein the piston is arranged so as to be able to be axially displaced and wherein the piston is constructed to block a fluid passage as a blocking element of a main valve device, wherein the fluid passage of the main valve device is blocked in the idle position of the armature, wherein the activation element is constructed to act in the activation position of the armature on the blocking member in such a manner that it releases the second opening at least in regions, and wherein the fluid passage of the main valve device is open in the working positions of the armature. The invention further relates to a system having such a proportional valve.

Electromagnetic proportional valve and system having a proportional valve

The invention relates to a drive device for activating a rotary slide for a fluid system of an at least in part electrically operated motor vehicle. The drive device comprises an electric motor having a motor output shaft, a rotary slide output shaft configured for activating a rotary slide, wherein the rotary slide output shaft is aligned so as to be orthogonal to the motor output shaft, and a magnet is disposed on an end region of the rotary slide output shaft, and a sensor unit which is configured for detecting a rotary position of the magnet and thus of the rotary slide output shaft.
