本发明涉及一种阀门传动机构，它有一个外壳(24)、一个电动机(13)，该电动机通过一蜗杆传动装置(14)的一个传动部件(9)作用于一操作杆(8)，该阀门传动机构还有一个与操作杆(8)相连的负荷传感器(17-20，28)。该负荷传感器具有一个开关(28)，该开关可通过一操纵机构来操作，该操纵机构经过一个离合器(23，27)可脱开地与传动部件(9)相连，其中，该离合器的离合动作状态与传动部件(9)相对外壳(24)的轴向位置有关。 The invention relates to a valve drive comprising a housing (24), a motor (13), which acts upon an actuating bar (8) by means of a drive element (9) in a spindle drive (14) and a load sensor (17-20, 28) which is connected to the actuating bar (8). Said load sensor (17-20, 28) comprises a switch (28), which is actuated by an actuating arrangement, which is connected in a detachable manner to the drive element (9) by means of a clutch (23, 27). The switching state of clutch is dependent upon the axial position of the drive element (9) in relation to the housing (24).
