3. Hydraulic pressure mechanism for solenoid proportional valve
The pressure oil that has had its pressure reduced by the pressure reducing valve flows to chamber
(h), then flows through passage 4 and the filter to become the pilot pressure to each solenoid.
The pressure of the oil is determined by the set load on spring 4.
