P1 第1作動流体
P2 第2作動流体
P2A 第3作動流体
P3 第4作動流体
従って、A1=A3であるから、F1=K1−K2となる。
ただし、A1は第1受圧面積。
P1は第1流体通路6から導入される第1作動流体の圧力。
A3は軸部11の断面積。
K1は第1ばね42の力。
K2は補助ばね41の力。
また、ソレノイド部20に電流が印加される場合には、弁部10はF2の力により作動して閉弁する。このF2は、次の式のような力になる。
F2=P1×A1−P1×A3+K1−K2+Sとなる。
従って、A1=A3であるから、F2=K1−K2+Sとなる。
ただし、Sはソレノイド部20の吸引力。
このため、弁体10は作動流体の力を受けることなく作動できる。
F1=P1×A1−P1×A3+K1−K2となる。
従って、A1=A3であるから、F1=K1−K2となる。つまり、この項は、第1実施例と同じである。
ただし、A1は第1受圧面積。
P1は第1流体通路6から導入される第1作動流体の圧力。
A3は軸部11の断面積。
K1は第1ばね42の力。
K2は補助ばね41の力。
次に、ソレノイド部20に電流が印加される場合には、弁部10はF2の力により作動して閉弁する。このF2は、次の式に示す力になる。
F2=P1×A1−P2A×A2+P3×A2+K1−K2+Sとなる。
従って、A1=A2=A3であり、PA2=P3であるから、F1=K1−K2+Sとなる。
ただし、Sはソレノイド部20の吸引力。
このため、弁体10は作動流体の力を受けることなく作動できる。
