  • Page 36: Hand Remote Controls

    COMPONENTS CX130 Hand remote controls In neutral the hand control is a closed center hydraulic valve. The inlet oil from the pilot pump is blocked at all four regulator spools (27 ). The ports (1), (2), (3), (4) are ported inside of the valve back to tank through the notches in the regulator spool (27).

  • Page 42: Cushion Valve

    COMPONENTS CX130 Cushion valve Purpose of cushion valve There is a cushion control valve plumbed between the arm and boom hand control valve and the control valve. The cushion valve prevents the control spool from returning to neutral very rapidly. The pilot oil is metered as ist returns to the hand control vale.

  • Page 46 COMPONENTS CX130 Piloting The pilot pressure coming from the remote control enters the cushion valve in B and pushes the spool E and F. The pilot pressure goes freely to the control valve work spool end through D port.. The oil in the opposite end spool of the control valve return to the tank through the port C, and the opened return filter port T.

  • Page 50 COMPONENTS CX130 Cushion cancellation When arm opening and the lever is returned to neutral, pressurized oil from control valve (a pilot of arm opening) flows into port "D" of the cushion valve. Electric signal is sent to a controller with hard mode at this time and the controller sends the signal to a solenoid valve.
