FIELD: electricity. ^ SUBSTANCE: linear actuating device consists of slide nut and leading screw that are performed with the possibility of axial movement relative to one another between the first and the second points that define stroke length at actuating the corresponding element by means of transmission. The device also includes incremental position sensors, namely at least two Hall sensors or reed switches aimed for position defining. In order to define the position initialisation procedure takes place. It provides nut and leading screw shift from the first point at leading screw or nut to the second point at leading screw or nut. The quantity of pulses from incremental position sensors are registered as stroke length index. Then the position is defined by the quantity of pulses. The aforesaid device is active before, during and after engine operation. ^ EFFECT: extension of operation capabilities. ^ 9 cl, 7 dwg |
