The poppet valve including a valve body with a plurality of passage channels, a plurality of closing elements, a plurality of guide means, and a catcher. Each passage channel opening into a valve seat. A closing element is mounted on each guide means movable in a stroke direction. A closing element is associated with each valve seat opposite in the stroke direction, so that valve seats can be closed by the closing elements. Guide means are connected to the catcher, each having a guide section with an inner cavity extending in the stroke direction and a support section bearing surface. The spring extends in the inner cavity of the guide section and is clamped between the bearing surface and the closing element. Guide means have a first stop surface towards the valve seat, closing elements have a second stop surface towards the first stop surface to limit closing element travel.
A poppet valve comprising a valve body with a plurality of passage channels (2a), a plurality of closing elements, a plurality of guide means, and a catcher, wherein each passage channel (2a) opens into a valve seat, wherein a closing element is mounted on each guide means so as to be movable in a stroke direction, wherein a respective closing element is associated with each valve seat opposite in the stroke direction, so that each valve seat can be closed by the respectively associated closing element, wherein each guide means successively comprises in the stroke direction a guide section, a support section and a fastening section, wherein each guide means is connected to the catcher via the fastening section, wherein the guide section comprises an inner cavity extending in the stroke direction, and wherein the support section comprises a bearing surface, wherein a spring extends in the inner cavity of the guide section and is clamped between the support surface and the closing element, and wherein the guide means comprises a single guide section extending in the stroke direction, characterized in that each guide means has a first stop surface oriented toward the valve seat, that each closing element has a second stop surface oriented toward the first stop surface, that the first and second stop surfaces are arranged to cooperate in such a way that they limit the maximum stroke of the closing element in the stroke direction, and in that the fastening section forms a positive connection to the catcher which acts in both directions of the stroke direction.
