Abstract
Filter device for a molding machine with at least one filter element for filtering plasticized material, in particular plasticized plastic, wherein, in a fluidically parallel arrangement relative to the at least one filter element, at least one valve element is provided, which is formed to prevent the plasticized material from flowing through the at least one valve element during an injection process in a closed position and to allow the plasticized material to flow through the at least one valve element in an open position, in order to make it possible to relieve the pressure on the at least one filter element after the injection process.
