SHOCK FUNCTION RETURN
After the engine clears the under water object, the
weight of the engine will increase the oil pressure be-
tween the memory piston (e) and shock piston (d) to
the level required to open the shock return valve (v),
inside the shock piston, allowing the oil to bleed back
through the shock piston into the down cavity. If re-
quired, additional oil will enter the down cavity
through the suction valve (g). This will return the en-
gine back against the memory piston (e) in to the orig-
inal running position.
