Technical description
The cylinders are made of cast iron (Fig. 11), while
the pistons are made of aluminium and have
traditional multiple compression rings. The high
pressure stage piston has an anti-wear coating.
The relative cylinder is given a self-lubricating
treatment.
Monobloc unit
The gooseneck, the pistons and the cylinders
also form a part of this unit.
The monobloc (Fig. 9) is made of aluminium
alloy, the two flanges with the ball and roller
bearings that support the gooseneck are oil-
tight with the monobloc due to the O-Rings
fitted.
The gooseneck and the connecting rods only
turn on roller or ball bearings (Fig. 10).
The three connecting rods are fitted on the
gooseneck with a single crank angle.
