Valve closure for a piston compressor valve and method for operating the valve closure
First Claim
1. A valve closure for a piston compressor valve, comprising a valve seat having a plurality of passage openings, comprising a shaft having a rotation axis (D), and comprising a closing element for opening and closing the passage openings which is rotatable about the rotation axis (D), wherein the valve seat comprises a planar end side into which the passage openings open, wherein the valve seat has a center (Z), and wherein the passage openings run radially to the center (Z),wherein the rotation axis (D) runs perpendicular to the end side and through the center (Z),wherein the closing element is designed in one piece, that the closing element is fixedly connected to the shaft, that the closing element has a center point (M) and a plurality of closing arms that run radially to the center point (M), that the shaft is mounted in the valve seat in such a manner that the shaft is rotatable about the rotation axis (D) as well as displaceable in a profile direction (L) of the rotation axis (D), such that each closing arm has a sealing face that is aligned toward the planar end side, and such that the closing arms are configured so as to be substantially complementary to the passage openings as a function of the rotation of the closing element which closes or opens the passage openings by way of the sealing faces.

Abstract
A valve closure for a piston compressor valve including: a valve seat having a plurality of passage openings, a shaft having an axis of rotation (D), and a rotatable closing element connected to the shaft for opening and closing the passage openings, the valve seat having a flat end face, to which the passage openings lead and a center (Z): the passage openings extending radially to the center (Z); and the closing element having a center point (M) and a plurality of closing arms extending radially to the center point (M). The shaft can be rotated about the axis of rotation and can be slid in the extension direction of the axis of rotation extending perpendicularly to the end face and through the center (Z); each closing arm having a sealing surface substantially complementary to the passage openings in accordance with the rotation of the closing element.

wherein the rotation axis (D) runs perpendicular to the end side and through the center (Z), wherein the closing element is designed in one piece, that the closing element is fixedly connected to the shaft, that the closing element has a center point (M) and a plurality of closing arms that run radially to the center point (M), that the shaft is mounted in the valve seat in such a manner that the shaft is rotatable about the rotation axis (D) as well as displaceable in a profile direction (L) of the rotation axis (D), such that each closing arm has a sealing face that is aligned toward the planar end side, and such that the closing arms are configured so as to be substantially complementary to the passage openings as a function of the rotation of the closing element which closes or opens the passage openings by way of the sealing faces.
- 16. A method for operating a valve closure of a piston compressor valve, wherein the valve closure comprises a valve seat having a plurality of passage openings, a closing element and a shaft having a rotation axis (D), wherein the closing element for opening and closing the passage openings is rotated about the rotation axis (D), wherein the closing element is formed in one piece and is fixedly connected to the shaft, that the shaft is seated in the valve seat so as to be rotatable about the rotation axis (D) and so as to be displaceable in the direction of the rotation axis (D), that the closing element by virtue of a fluid pressure prevalent on the piston compressor valve is lifted in a self-acting manner in the direction of the rotation axis (D), and that the closing element after lifting from the valve seat is rotated in a manner actively driven by the shaft and the passage openings are thus completely opened.
