摘要： In the production of a reaction mixture which forms plastic material, in particular foamed plastic material, from at least two flowable reaction components, the inlet members or other switch-over members which must be switched over in a precise fashion, and controlled by a sliding valve comprising a slide which is assigned a restoring spring which operates in opposition to a moving electromagnet, and a holding electromagnet. First, the holding electromagnet is fully activated whereupon the moving electromagnet is activated. Following the build-up of force of the moving electromagnet, the holding electromagnet is switched off so that the inlet member or other switch-over member opens abruptly.
