Abstract
A solenoid valve includes a magnet assembly and a valve cartridge having an armature guided movably inside a capsule, a valve insert, a slide which is guided movably inside the valve insert and has a closing element and a sealing element, and a valve body with a valve seat. A main valve includes the sealing element and the valve seat. The slide is formed in two parts with the sealing element as the first part and the closing element as the second part. When the valve is not energized, the valve is open, and when the valve is energized, the sealing element seals in the valve seat. The sealing element and the closing element are made of different materials, and the material of the sealing element allows a partial elasticity of the slide while the material of the closing element allows a partial stiffness of the slide.
