Abstract
Cooling spray jet comprising a supply inlet, a discharge outlet, a reaming connecting the inlet and the outlet, the outlet having a given cross-sectional area, a valve comprising a plug free to slide in the reaming and bearing in contact with a valve seat in a closed state. The valve has two open states after a first phase in which the plug separates from the valve seat, with different ranges of fluid pressures, the cross-sectional area between the plug and the reaming of each opening state being different from the cross-sectional area of the other state, one of these opening states having a cross-sectional area that regulates the fluid flow at the discharge outlet and the other opening state having a cross-sectional area such that the flow is regulated by the cross-sectional area of the outlet.
