PROBLEM TO BE SOLVED: To accurately acquire a relationship of a pressure difference between a boosting linear valve and a decompression linear valve and an opening/closing balance current, in a fluid pressure supply device including a regulator using a spool-type valve mechanism, the boosting linear valve for regulating pilot pressure which is supplied to the regulator, and the decompression linear valve.SOLUTION: When a spool 110 is moved to the other end side (decompression side) before boosting opening/closing balance current acquisition processing is performed, a boosting linear valve 26 is opened, and the spool 110 is moved to one end side (boosting side). When the spool 110 is moved to one end side (boosting side) before decompression opening/closing balance current acquisition processing is performed, a decompression linear valve 28 is opened, and the spool 110 is moved to the other end side (decompression side).SELECTED DRAWING: Figure 2
【課題】スプール式の弁機構を用いたレギュレータと、そのレギュレータに供給するパイロット圧を調整する増圧リニア弁および減圧リニア弁を含んで構成された液圧供給装置において、増圧リニア弁および減圧リニア弁の差圧と開閉均衡電流との関係を精度よく取得する。【解決手段】増圧開閉均衡電流取得処理を行う前、スプール110が他端側(減圧側)に移動している場合に、増圧リニア弁26を開弁してスプール110を一端側(増圧側)に移動させるとともに、減圧弁開閉均衡電流取得処理を行なう前、スプール110が一端側(増圧側)に移動している場合に、減圧リニア弁28を開弁してスプール110を他端側(減圧側)に移動させる。【選択図】図2
