4.1 Hydraulic system
Exchange line 2->1
(fig.4) - when fluid attains the adjusting spring pressure
calibration "PS1", the pilot conduit opens causing the displacement of the
chamber from the position "a" to the position "b"
Activation line 2
(fig.3) - with valve in position "b" the pump pushes lubricant to
line 2. Line 1 is
discharge phase.
Exchange line 1->2
(fig.2) - when fluid reaches the adjusting spring pressure
calibration "PS1", the pilot conduit opens causing the displacement of the
chamber from the position "b" to the position "a"
Activation line 1
(fig.1) - with valve in position "a" the pump pushes lubricant
to line 1. Line 2 is
discharge phase.
