The invention relates to an electromagnetic valve (1), in particular for closing a bypass in a coolant circuit of an internal combustion chamber, comprising an energizable coil (3) and an armature (2) which can be moved in the direction of a core by energizing the coil and which applies a force onto a valve lifter (8) in the direction of a closing position when the coil is energized, in particular against a spring force of a restoring spring (18). According to the invention, a pin (12) is provided which can be moved together with the armature in order to adjust the valve lifter in the direction of the closing position when the armature is energized. A force can be applied onto the valve lifter via the pin by moving the armature in the energized state in the direction of the closing position, and the pin is spring-loaded by a pressure-limiting spring (13) in the direction of the closing position of the valve lifter and can be moved out of the pin closing position via the valve lifter when the valve lifter is moved in an axial manner in order to open the electromagnetic valve even when the armature is moving in the direction of the core (6) against the spring force of the pressure-limiting spring. |
