Abstract
A coaxial valve includes an actuating drive, a valve housing (11), a valve sleeve (12) that is longitudinally slidable in the valve housing (11) between open and closed positions, and a closing body (13) arranged coaxially at one end of the valve sleeve (12). In the closed position, the valve sleeve seals against the closing body. In the open position, the valve sleeve is spaced from the closing body, to open a valve opening cross-section (V). The actuating drive includes an electric servomotor (21) with a linear actuator (22), and a transmission mechanism (30) for transmitting the linear movement of the actuator to the valve sleeve. The transmission mechanism includes a rocker lever with a first end articulately connected to the linear actuator, a second end articulately connected to the valve housing, and a middle section articulately connected to the valve sleeve.
