| 摘要 |
The valve actuating device has two control surfaces (6a) and a connection mechanism (15,16) that is displaced in a position, in which it prevents control movements of the latter control surface to a control movement transmitted from the former control surface on a valve (3). The connection mechanism is displaced in another position, in which the control surface actuates the valve. A motion transmission mechanism and another motion transmission mechanism have a common valve head (14) on the valve. |
