  • Patent number: 9611845
    Abstract: Equipment for continuous regulation of the flow rate of fluid in a reciprocating compressor which has a compression chamber with a piston reciprocally movable therein. The compression chamber has an inlet valve and an outlet valve which delivers fluid to a reservoir. A translation device is movable to open the valve and allow closing of the valve. An actuator engages the translation device and includes a rod. The rod has a magnitizable central element located between solenoids of an electromechanical device. The central element is located in a prefixed position with respect to the solenoids under the resilient loading of a resilient device. Detectors are provided for detecting the position of the piston, the pressure in the reservoir and the position of the actuator.

  • Patent number: 8641008
    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.
