Abstract
A system for actuation in an admission valve of a gas compressor including an admission valve being configured to allow the input of gas inside the cylinder upon the axial movement of the piston in a first axial direction; and a discharge valve configured to allow the output of gas from inside the cylinder upon the axial movement of the piston in a second axial direction opposite to the first axial direction. The system includes at least one actuator element, operatively associated with the admission valve, capable of keeping the admission valve open when the electric motor stops and starts-up. The actuator element is also capable of allowing opening and closing of the admission valve upon the regime of work of the electric motor. The present development also refers to refrigeration equipment which includes the above-mentioned gas compressor.
