    摘要: The invention relates to a die assembly for a pelletizing apparatus, the die assembly having a pressure regulating device that has a base member, a flow channel, and an annular channel. The base member has a fluid inlet side and a fluid outlet side. The flow channel is formed in the base member to provide a fluid-conducting connection between the fluid inlet side and the fluid outlet side. The annular channel section is connected to the flow channel in a fluid-conducting manner and formed in the region of the fluid outlet side. The invention is characterized by a flow cross-section regulating element for influencing a flow cross-section of the annular channel section. The regulating element is movable relative to the annular channel section and/or the flow channel.
