4.2 OPERATIONS
1) DOWN position
The fluid from port B pushes up stop ring (9) of
poppet(10) until the ring comes into contact with
adjust screw(6),as it reaches chamber(R).
Consequently,the extent choke (C) is opened is
determined by the positioning of adjust screw
(6):that is,when adjust screw(6) is screwed in
clockwise,the opening of chock(C) decreases and
the lowering speed of the lift arm slows
down;whereas the opening of choke(C) increases
and the lowering speed of the lift is accelerated
when the adjust screw is unscrewed
counterclockwise.When the adjust screw screwed
in completely,the poppet comes into contact with
body seat(S) and the choke is closed
completely,so the lift arm stops.
2) Up position
The flow port A,overcoming the force of
spring(11),pushes up poppet (10) and choke(C)is
fully opened regardless of the position of adjust
screw(6).Thus the fluid flows to port B and the
cylinder,which results in raising the lift arm.
