Poppet valve, plate valve, with a longitudinal axis (L), with a valve seat having a plurality of valve seat passage channels, with a catcher arranged at a distance from the valve seat in the direction of the longitudinal axis (L), and with a sealing element arranged movably between the valve seat and the catcher for opening and closing the valve seat passage channels. One of the valve components formed as the valve seat or the catcher having a plurality of passage channel limiting sections and a plurality of web portions, each extending mutually at an angle (α), wherein at least one of the valve components formed as valve seat or catcher is produced at least in sections by additive manufacturing, and wherein at least one of the passage channel limiting sections is dimensioned shorter in the direction of the longitudinal axis (L).
A poppet valve with a longitudinal axis (L), with a valve seat having a plurality of valve seat passage channels, with a catcher arranged at a distance from the valve seat in a direction of the longitudinal axis (L), and with a sealing element arranged movably between the valve seat and the catcher for opening and closing the valve seat passage channels, and with a damping element disposed between the sealing element and the catcher, at least one of the valve seat and the catcher having a plurality of passage channel limiting sections and a plurality of web portions, the passage channel limiting sections forming valve seat passage channels and/or catcher passage channels, wherein the passage channel limiting sections and the web portions each extend mutually at an angle (a), and wherein all the passage channel limiting sections are dimensioned shorter in the direction of the longitudinal axis (L) of the respective valve component than the web portions of the respective valve component, wherein at least one of the valve seat and the catcher is produced at least in sections by additive manufacturing, wherein the web portions of the respective valve component are free of support surfaces for the sealing element or the damping element, wherein the web portions of the respective valve component, on a side facing the sealing element or the damping element, are recessed in the direction of the longitudinal axis (L) with respect to one of the passage channel limiting sections, wherein the web portions extend radially with respect to the longitudinal axis (L), wherein the passage channel limiting sections are arranged spaced apart from each other in a radial direction and connected to the web portions, and wherein, in the direction of the longitudinal axis (L), the length of the passage channel limiting sections decreases towards the longitudinal axis (L), wherein, in the direction of the longitudinal axis (L), the passage channel limiting section closest to the longitudinal axis (L) has a length of no more than half the web portion and wherein, in the direction of the longitudinal axis (L), the length of the passage channel limiting sections decreases continuously towards the longitudinal axis (L).
A method for manufacturing valve components of a poppet valve, wherein the valve components comprise at least one of a valve seat and a catcher, by generating by additive manufacturing a support structure comprising a plurality of web portions, by also creating by additive manufacturing a plurality of passage channel limiting sections connected to the web portions, wherein the passage channel limiting sections are arranged such that valve seat passage channels and/or catcher passage channels are formed between the passage channel limiting sections, and wherein all the passage channel limiting sections are dimensioned shorter in the direction of the longitudinal axis (L) than the web portions of the respective valve component, and wherein the web portions of the respective valve component are formed free of support surfaces for a sealing element or a damping element, wherein the web portions of the respective valve component are recessed in the direction of the longitudinal axis (L) relative to the passage channel limiting sections, wherein the web portions are formed extending radially with respect to the longitudinal axis (L), wherein the passage channel limiting sections are arranged spaced apart from each other in a radial direction with respect to the longitudinal axis (L) and connected to the web portions, and wherein, in the direction of the longitudinal axis (L), the passage channel limiting sections are formed with decreasing length towards the longitudinal axis (L), wherein, in the direction of the longitudinal axis (L), the passage channel limiting section closest to the longitudinal axis (L) is formed with a length of at most half the length of the web portion in the longitudinal direction (L) and wherein, in the direction of the longitudinal axis (L), the length of the passage channel limiting sections decreases continuously towards the longitudinal axis (L).
