TR00466

When accumulator pressure again reaches its upper limit, accumulator pressure combined with force of

spring (13) will overcome the force of pilot spring (10) and shift pilot valve (9) spool downward (as shown).

This will remove accumulator pressure from the left end of charging valve (8) spool and permit pump

pressure to again shift charging valve spool to the left (as shown). Check valve (7) will again be seated by

higher accumulator pressure and block the path between pump (1) and accumulator (3).
