reach too. The pressure in the annular space 36 is also propagated into the space 20 via the passage 26, so that a pressure equilibrium occurs. Thereby, the space 20 is cleaned. Upon movement of the valve body 18 in the opening direction, the forced pressure medium can flow out of the space 20 via the channel 26 to the outside. This passage is
It is sized to allow accommodation of the entire pressure medium to be extruded. When the valve body moves into the closed position, this pressure medium is sucked in again through the channel 26. Therefore, no exchange of pressure medium with the surroundings takes place. The filter sieve 29 also
Particles are prevented from entering the armature space 20 and causing armature sticking. The filter screen simultaneously acts as a hydraulic resistance and damps the movement of the valve body.
