1. Neutral position of control valve
When the control valve is in neutral position, bucket valve rod 6 and boom union valve rod 8 are in neu-
tral position. As for the closed neutral position structure, LS pressure is zero, the variable pump under
the action of pump outlet pressure is in minimum displacement and the pump is in low-pressure standby
state.
As for the closed neutral position structure of valve rod, oil line between big & small cavities of cylinder
and valve rod is kept closed, the pressure of control valve oil inlet, which is the same as that of pump
outlet, is in low-pressure state.
