Valve actuation system for a suction valve of a gas compressor for refrigeration equipment

System for actuation in an admission valve of a gas compressor, the gas compressor comprising at least:

• one set formed by a cylinder and a piston;
• one electric motor operatively associated with said set, the electric motor being capable of providing an axial movement of the piston to compress the gas inside the cylinder, the 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;
• one 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,
• one actuator element operatively associated with the admission valve, the actuator element being capable of keeping the admission valve open when the electric motor stops and starts-up, the actuator element being further capable of allowing opening and closing of the admission valve upon the regime of work of the electric motor,
• the system comprising at least:
• one magnetic element for dragging mechanically associated with an element of electric drive, the magnetic element for dragging further being and magnetically associated with a rotor of the electric motor,
• the magnetic element for dragging being capable of axially moving in a first axial direction upon the regime of work of the electric motor to activate the element of electric drive,
• the magnetic element for dragging being capable of axially moving in a second axial direction, opposite to the first axial direction, upon the stop of the rotor of the electric motor) to deactivate the element of electric drive;
• and
• one electro-mechanical element electrically associated with the element of electric drive, the electro-mechanical element further being mechanically associated with the actuator element,
• the electro-mechanical element being capable of axially moving in a first axial direction, upon the activation of the element of electric drive, to pull the actuator element,
• the electro-mechanical element being capable of axially moving in a second axial direction, opposite to the first axial direction, upon the deactivation of the element of electric drive, to push the actuator element.
