Piston compressor valve and method for operating a piston compressor valve
First Claim
1. A piston compressor valve comprising a valve seat having a plurality of passage openings, comprising a closing element for opening and closing the passage openings is rotatable about a rotation axis (D), and comprising an actuator drive for rotating the closing element, wherein the valve seat has an end side into which the passage openings open, wherein the closing element is designed integral, wherein the closing element is connected to the actuator drive so as to be movable in a self-acting manner in a profile direction of the rotation axis (D) such that the closing element is rotatable about the rotation axis (D) by the actuator drive as well as displaceable in the self-acting manner in the profile direction of the rotation axis (D) in relation to the end side, and comprising a sensor for detecting a state variable (E) of the piston compressor valve, and comprising an actuating device which activates the actuator drive as a function of the state variable (E).

Abstract
A piston compressor valve including a valve seat having a plurality of through openings including a closing element which is rotatable about an axis of rotation (D) for opening and closing the through openings and having an actuating drive for rotating the closing element, wherein the valve seat has an end face into which the through openings lead, wherein the closing element is movably connected to the actuating drive in the running direction of the axis of rotation (D), such that the closing element is both rotatable about the axis of rotation (D) and also movable in the running direction of the axis of rotation (D) relative to the end face, and having a sensor for detecting a condition variable (E) of the piston compressor valve, and having a control device which activates the actuating drive as a function of the condition variable (E).

- 13. A method for actuating a piston compressor valve, wherein the piston compressor valve comprises a valve seat having a plurality of passage openings, a closing element that for opening and closing the passage openings is rotatable about a rotation axis (D), and an actuator drive for rotating the closing element, wherein the closing element is designed so as to be integral and fixedly connected to the rotation axis (D), wherein the rotation axis (D) is mounted so as to be displaceable in the profile direction of the rotation axis (D), wherein the closing element as a function of the pressure of an operating gas acting on the valve is displaced in a self-acting manner in the profile direction of the rotation axis (D) and bears on the valve seat or is lifted from the valve seat, wherein a state variable (E) of the piston compressor valve is measured, and wherein the closing element is rotated about the rotation axis (D) by the actuator drive as a function of the state variable (E).
