Shuttle valve having two drives
First Claim
1. A shuttle valve for the gas-tight interruption of a flow path, comprisinga valve housing having a wall which has an opening for the flow path and a valve seat surrounding the opening,a valve disc which is arranged on a rotatably mounted shaft, anda drive unit by means of which the valve disc can be moved along a displacement curvefrom an opened position leaving the flow path essentially unobstructed over the cross-section of the openinginto a closed position, in which the flow path is sealed gas-tight by a sealing contact between the valve disc and the valve seatby swiveling the valve disc from the opened position by a rotational movement about the pivot axis of the shaft andby moving the valve disc by a linear movement parallel to the pivot axis in the direction of the valve seat into the closed position,whereinthe drive unit hasa first drive for carrying out the rotational movement about the pivot axis anda second drive for carrying out the linear movement parallel to the pivot axis,a control unit is provided, andthe first drive and the second drive being actuatable by the control unit in such a way that the displacement curve can be produced, wherein the displacement curve is programmable or programmed in the control unit.

Abstract
The invention relates to a shuttle valve for interrupting a flow path (F), comprising a valve housing (1) having a valve seat (4) surrounding an opening (3) for the flow path (F). A valve disc (5) is arranged on a rotatably mounted shaft (6). By means of a drive unit (7), the valve disc (5) can be swiveled along a defined displacement curve (K1; K2; K3) from an opened position and leaving the flow path (F) unobstructed over the cross-section of the first opening (3) by a rotational movement about the pivot axis (8) of the shaft (6) and can be moved by a linear movement parallel to the pivot axis (8) in the direction of the valve seat (4) into a closed position so that the flow path (F) is sealed gas-tight by a sealing contact between the valve disc (5) and the valve seat (4). According to the invention, the drive unit (7) has a first drive (9a) for carrying out the rotational movement about the pivot axis (8) and a second drive (10a) for carrying out the linear movement parallel to the pivot axis (8). By means of a control unit (11), the first drive (9a) and the second drive (10a) can be actuated so that a variable displacement curve (K1; K2; K3) can be produced.

1. A shuttle valve for the gas-tight interruption of a flow path, comprising
a valve housing having a wall which has an opening for the flow path and a valve seat surrounding the opening, a valve disc which is arranged on a rotatably mounted shaft, and a drive unit by means of which the valve disc can be moved along a displacement curve from an opened position leaving the flow path essentially unobstructed over the cross-section of the opening into a closed position, in which the flow path is sealed gas-tight by a sealing contact between the valve disc and the valve seat by swiveling the valve disc from the opened position by a rotational movement about the pivot axis of the shaft and by moving the valve disc by a linear movement parallel to the pivot axis in the direction of the valve seat into the closed position, wherein the drive unit has a first drive for carrying out the rotational movement about the pivot axis and a second drive for carrying out the linear movement parallel to the pivot axis, a control unit is provided, and the first drive and the second drive being actuatable by the control unit in such a way that the displacement curve can be produced, wherein the displacement curve is programmable or programmed in the control unit.
