- a magnetic drive is provided for moving the hollow valve member as an actuator having an attached to the outside of the valve member armature, wherein spaces in the direction of movement on both sides of the armature via a passage having a defined cross section are interconnected.
- the cross section of the passage is selected such that the closing movement of the valve member is slowed down against the valve closing part with the valve seat.
- DE 102005012851 A1 has already proposed, in the case of a coaxial valve, to displaceably mount the valve seat in the axial direction of movement of the hollow valve part and thereby to open the valve seat in the direction of the hollow with the medium under pressure in the hollow valve part Apply pressure to valve part; solely for the pertinent solution, a connecting channel is provided, which connects the valve hollow interior with the back of the valve seat, in order to ensure that the valve seat of the valve closing member is always pressurized in the direction of the hollow valve member.
- the invention therefore has for its object to provide in a cost effective and reliable manner a valve device which prevents overheating of the hollow valve member on the valve closure member while still allowing fast response and safety lt, that it can not come to an unwanted opening of the valve device due to pressure fluctuations during operation.

- a second step the fluid flows through the one flow guide 34, by which a direction reversal of 180 ° in the flow path is effected, and directly thereafter in a third step, the further flow guide 36, which in turn causes a further reversal of direction of 180 ° in the flow path ,

- valve device If the valve device is opened; Thus, if the hollow cylindrical valve part 6 moves away from the end face of the valve closing part 10 arranged stationary in the housing 4, the fluid exits from the valve part 6 and is radially deflected outwards in a throttled manner 90 ° outwards along the closing plate 32 of FIG Valve-closing part 10 out. Subsequently, it is still at reduced speed on the inside of the sealing insert 50 and thanks to the one flow guide 34 with the outwardly facing control edge 45 of the valve closing member 10, it comes to the already described deflection or reversal of direction of the fluid by 180 °. When the valve position is slightly open, the resulting fluid flow is strongly throttled, which increases the stability of the fluid guide.
- the fluid streams at the fluid inlet E and at the fluid outlet A of the valve device are then directed parallel, so that flow losses can not lead to turbulent flow paths within the filter device, which otherwise favors cavitation, which occurs in particular on the valve closing part 10.
- the already described throttling of the fluid flow during the opening process is also present in the opposite direction when closing the valve device, so that the valve member 6 only muffled comes into contact with the valve closing member 10, which helps avoid the dreaded closing strikes. It is also achieved by the two flow-guiding devices 34, 36 that the valve part 6 remains held in the closed position (see Fig.
