Abstract

The present invention refers to a method for actuating semi-controlled valve that acts in synchronism with the compression cycles of an alternative compressor and to a system for actuating a multi-suction alternative compressor semi-controlled valve. Said method comprises at least a step of detecting at least one compression peak (1) in the course of at least one mechanical cycle (2) of the alternative compressor; and at least a step of switching the functional status of at least an alternative compressor semi-controlled valve (3) based on detecting at least one compression peak (1) in the course of at least one mechanical cycle (2) of the alternative compressor (5).

First claim

1 - 20 . (canceled)

21 . A system for actuating a multi-suction alternative compressor semi-commanded valve, comprising:
at least one semi-commanded valve configured to be electrically actuated by at least one magnetic field generator; at least one data processing core; and at least one sensor, wherein:
the data processing core is configured to receive electric stimuli from the at least one sensor and configured to generate electrical stimuli for the at least one magnetic field generator;
the multi-suction alternative compressor comprises a compression cylinder fluidly connected to at least two suction orifices and at least one discharge orifice;
each suction orifice of the at least two suction orifices is cooperative with at least one suction valve; and
at least one of the suction valves comprises a semi-commanded valve;
the at least one sensor comprises a sensor capable of m asuring is configured to measure at least one parameter intrinsic in the function of said the alternative compressor;
the at least one data processing core is configured to determine a peak of the at least one parameter measured by the sensor, and is configured to energize the at least one magnetic field generator based on the measurement of the peak of the parameter measured by the at least one sensor.
