<p>This nozzle is (15) adapted to direct a jet (J<SUB>15</SUB>) of oil under pressure on internal combustion engine. It has a variable outlet section, and it is provided with mechanical means (154, 155) adapted to control its outlet section on the basis of the pressure (P<SUB>8</SUB>) of a fluid under pressure provided to these mechanical means, independently of the oil going through (F<SUB>6</SUB>) the outlet (152) of the nozzle. In the lubrication system an auxiliary line is provided with first proportional means controlling oil flow (F<SUB>6</SUB>) toward a nozzle (15). A control line connects a main line or the auxiliary line, upstream of the first proportional means, to mechanical means (154, 155) adapted to control the outlet section of the nozzle (15). The control line is provided with second proportional means controlling the pressure (P<SUB>8</SUB>) of oil delivered (F<SUB>8</SUB>) to said mechanical means (154, 155). The nozzle can be used as a piston cooling nozzle to direct oil toward a piston of an internal combustion engine.</p> |
