Abstract

The invention relates to a nozzle for laser cutting, comprising a nozzle body (1) comprising a first axial passage (5) , an external cover (13) comprising an axial housing (7), the nozzle body (1) being arranged at least partially in said axial housing (7) , and a mobile element (3) comprising a second axial passage (4) and a front part (3a) forming a skirt said mobile element (3) being arranged between the external cover (13) and the nozzle body (1) and being able to move in translation in the axial housing (7) in the external cover (13), and an elastic element (8) arranged in the axial housing (7), between the external cover (13) and the nozzle body (1). According to the invention, the mobile element (3) is able and designed to be moved in translation in the axial housing (7) in the direction of the first outlet orifice (14) under the effect of a gas pressure of said assist gas (23) that is applied in said axial housing (7) and is exerted on said mobile element (3), said elastic element (8) exerting an elastic return force on the mobile element (3), tending to oppose the movement in translation of the mobile element (3). Associated laser head and installation. Laser cutting process implementing such a nozzle.
