Abstract:
Method for controlling the position of an electromechanical actuator for reciprocating compressor valves. The actuator includes a member (302) movable in a direction parallel to the direction for opening and closing the obturator of the valve (12), between a position corresponding to the closed position and a position corresponding to the open position of the obturator (11). The member (302) is provided with a mechanism (322) able to act on the obturator (11) and with a magnetizable portion (312) co-operating with two electromagnets (102, 202) and being arranged in equilibrium between the latter via a suitable mechanism.
