Shock Function With Valves Closed
Should the drive unit strike a submerged object while
in forward motion, the shock rod (a) will extend from
the cylinder (l). Oil inside the up cavity is locked in a
static position by the closed up fast transfer valve (j),
the closed down slow transfer valve (i) and closed
down fast transfer valve (h). Fluid will attempt to exit
the cylinder through the interconnecting passage
back into the accumulator (c). The closed up fast
transfer valve (j) will prevent the fluid return. As the
shock rod extends outward, the pressure inside the
up cavity will reach sufficient pressure to open the
shock valve (p) which opens at 880-1110 psi. Oil will
flow into the cavity created as the shock rod & shock
piston (n) moves away from the memory piston (m).
