Abstract
According to the invention, an internal combustion engine piston cooling nozzle comprises a nozzle body, a transverse fixing plate and screwing means such as a fixing screw offset laterally at a distance between axes. The nozzle body comprises an axial bore containing valve means and a transverse bore receiving a cooling fluid outlet duct. The peripheral wall is thick around the transverse bore. The diametrally opposite portion of the peripheral wall is thinner because of the presence of an external recess facing the fixing screw. Thus the fixing screw may be moved closer, by reducing the distance between axes, which reduces the overall size of the cooling nozzle.
