Actuating device

An actuating device for actuating an externally connected valve, comprising:

• a housing;
• a coil body in said housing, said coil body having a coil winding and enclosing a pole tube at least partially, said pole tube being formed as a receiving sleeve fixed at a free end region thereof at a fixed bearing point;
• a pole core connected to said free end region of said pole tube and having first and second support parts forming said fixed bearing point, delimiting a gap therebetween and clampingly fixing said free end region therein;
• an armature guided for longitudinal displacement at least in said receiving sleeve within an armature space therein and interacting with an actuating part for actuating a respective valve part;
• and
• a reset device acting on said receiving sleeve at a loose hearing point thereof and applying a force to said receiving sleeve in a direction away from said fixed bearing point, said receiving sleeve including a bottom part located outside said housing and having a widening extending radially outwardly relative to a remaining outside diameter of said receiving sleeve, said widening being at a site of a change in diameter and having a deflection region against which said reset device acts.

• and
• a reset device acting on said receiving sleeve at a loose hearing point thereof and applying a force to said receiving sleeve in a direction away from said fixed bearing point, said receiving sleeve being cylindrical from said loose bearing point toward said fixed bearing point and adjoining said pole core, said pole core being received in and in contact with said receiving sleeve along a guide distance, said receiving sleeve including a bent transition region between said fixed bearing point and said guide distance, a free end region of said bent transition region leading to a constriction site between said first and second support parts.

• and
• an armature guided for longitudinal displacement at least in said receiving sleeve within an armature space therein and interacting with an actuating part for actuating a respective valve part.
