Main Control Valve (Kayaba)
OVERLOAD RELIEF VALVE (69, TOTAL: SIX
PLACES)
1.
The overload relief valve is located
between cylinder port (HP) and low
pressure oil passage (LP). Pressurized oil
at cylinder port (HP), flows through an
orifice in piston (C), to fill internal cavity
(G). Due to the difference in area between
(A) and (B) on which the hydraulic
pressure acts, main poppet (D) seats on
sleeve (K).
2.
When pressure in cylinder port (HP) rises
and exceeds the relief valve setting, pilot
poppet (E) opens. Pressurized oil then
flows through pilot poppet (E) into low
pressure oil passage (LP), passing
through hole (H).
3.
As pilot poppet (E) opens, pressurized oil
flows through orifice (I) so that pressure on
back of piston (C) lowers to move piston
(C). As a result, piston (C) seats on pilot
poppet (E).
4.
Pressurized oil in passage (HP) flows
through orifice (F) in piston (C) so that
pressure on back of main poppet (D)
moves main poppet (D). Pressurized oil
then flows into passage (HP) and directly
into passage (LP).
