Abstract (en)
[origin: EP1653060A1] A simple method for fitting an oil spray jet into a crankshaft housing in order to cool the underside of a piston has the shaped jet (10) secured into a bore (4) leading to an oil duct (22) for a main bearing. The spray jet end is secured by a clip (12) with a shaped tag (12b) locating into a blind hole (14) to prevent the jet from rotating. The other end of the jet insert (6) is secured in a widened recess (4a), opening into the oil duct, by a sprung split ring clipped into a retaining groove in the insert shaft.
