Patent ID: 8777589

Claim:
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 system comprising at least: one first main movable magnetic element magnetically associated with a rotor of the electric motor, and one second main movable element operatively associated with the first main movable magnetic element, the second main movable element further being mechanically associated with the actuator element, the first main movable magnetic element and the second main movable element being configured to interact to each other to keep the admission valve open when the electric motor stops and starts-up and further to allow opening and closing of the admission valve upon the regime of work of the electric motor.
