This disclosure relates to a proportional valve arrangement for refrigerant, with a valve housing having a valve body chamber, a valve body which is arranged within the valve body chamber and configured to be transferable between a first position and a second position. The valve housing includes a first sealing seat and a second sealing seat, and the valve body which is transferable between the first sealing seat and the second sealing seat.

Proportional valve assembly for refrigerants

An electromagnetic actuator including an actuator unit; and an actuation unit acting in an axial direction, wherein the actuator unit includes a coil generating a magnetic field and including a pole core that is arranged within the coil, wherein at least two permanent magnets are arranged adjoining a face of the pole core in the axial direction so that the at least two permanent magnets are applicable to the face of the pole core and movable in the axial direction so that the at least two permanent magnets are drivable by the coil independently from each other.

Electromagnetic actuator

The invention relates to a hydraulic transmission valve with a magnetizable housing which is integrally configured in one piece with a pole core cone. The transmission valve according to the invention facilitates comfortably coupling in particular startup clutches, shifting clutches or synchronization clutches in a friction locking manner. Still using a transmission valve of this type is facilitated for fewer to no transmission oil changes. Furthermore a transmission valve of this type can also be used in countries with inferior transmission oil quality. The housing includes a connection. The connection defines an anchor stroke and a concentric arrangement between the pole core cone and a pole tube. Thus, the pole tube is fixated the magnetizable pole flange. An anchor that is exclusively supported in the pole tube is magnetically separated from the pole tube through a separation layer with a thickness of 0.01 mm to 0.06 mm.

Hydraulic transmission valve

An actuating device for a transmission of a motor vehicle has a housing and two pistons moveably arranged in the housing. A coupling part is arranged between the two pistons and is acted on by the two pistons so as to be moved by the two pistons. The coupling part is connected to a shifting part of the transmission and is made, at least on a surface of the coupling part, of wear-resistant material. The two pistons are loosely seated on the coupling part so that these parts can align themselves properly relative to one another after mounting.
