因而A2>A1，故活塞上方液壓作用力大于活塞下方液壓作用力。在P1、P2同步增長(zhǎng)
過(guò)程中當(dāng)活塞上、下兩端液壓作用之差過(guò)彈簧3的預(yù)緊力時(shí)，活塞便開(kāi)始下移

lower ends of the hydraulic spring preload effect exceeds 3, the piston starts
。當(dāng)P1和P2增長(zhǎng)到一定值Ps時(shí)活塞2內(nèi)腔中的閥座與閥門(mén)1接觸，進(jìn)油腔與出油腔
即為隔。此即比例閥的平衡狀態(tài)。
若進(jìn)一步提高P1則活塞將回升，閥門(mén)再度開(kāi)啟。油液繼續(xù)流入出油腔使P2也升高但由于A2＞A1，P2尚
高達(dá) 300 l/min氣量bar:在50%信號(hào)時(shí)的典型值為0.85 l/mi4 bar:在50%信號(hào)時(shí)的典型值為1.75
Thus A2> A1, it is above the hydraulic piston force is greater than
 the hydraulic force of the piston downward. In P1, P2 synchronous
