The present invention refers to a system for actuation in an ad mission valve (5) of a gas compressor (1) comprising at least: one set formed by a cylinder (2) and a piston (3); one electric motor (4), operatively associated with said set, capable of providing an axial movement of the piston (3) to compress the gas inside the cylinder (2), the admission valve (5) being configured to allow the input of gas inside the cylinder (2) upon the axial movement of the piston (3) in a first axial direction; and a discharge valve (6) configured to allow the output of gas from inside the cylinder (2) upon the axial movement of the piston (3) in a second axial direction opposite to the first axial direction. The system comprises at least one actuator element (7), operatively associated with the admission valve (5), capable of keeping the admission valve (5) open when the electric motor (4) stops and starts-up. The actuator element (7) is also capable of allowing opening and closing of the admission valve (5) upon the regime of work of the electric motor (4). The present invention also refers to a gas compressor (1) which comprises the above-mentioned system. The present invention also refers to a refrigeration equipment which comprises the above-mentioned gas compressor (1).
