Device for continuous regulation of the gas flow rate processed by a reciprocating compressor

A device for continuous regulation of a gas flow rate processed by a reciprocating compressor, wherein said reciprocating compressor comprises at least a first compression piston associated with a first cylinder, and able to create a pressure which is variable over a period of time;

• a second piston, acting independently of said first piston inside a second cylinder, which is in free communication with said first cylinder, and which acts on a dead space in said second cylinder;
• the device comprising a third fluid mechanics cylinder, which moves said second piston, and wherein said third fluid mechanics cylinder is activated by means of a compressed fluid, supplied by means of an independent hydraulic system, in order to obtain continuous variation of said dead space, and wherein said hydraulic system has an accumulator and at least one pair of on-off directional solenoid valves, each of said on-off directional solenoid valves supplied with said compressed hydraulic fluid, obtained from said hydraulic system.
