Muaj nuj nqi: - Nrog de-energized solenoids (7 thiab 8), lub hauv paus txoj hauj lwm ntawm tus tswj spool (2) los ntawm compression springs (3 thiab 4) ntawm lub caij nplooj ntoos hlav daim hlau (5 thiab 6) - ncaj qha kev khiav hauj lwm ntawm cov tswj spool (2) los ntawm tswj ib tug proportional solenoid, xws li solenoid "b" (8) → Tshem tawm ntawm cov tswj spool (2) mus rau sab laug proportional rau cov hluav taws xob input teeb liab → Kev sib txuas ntawm P mus rau A thiab B rau T ntawm orifice-type cross-sections nrog kev nce qib Flow yam ntxwv - Hloov tawm ntawm lub solenoid (8) → Lub caij nplooj ntoos hlav compression (3) nqa cov tswj tuav (2) rov qab mus rau hauv qhov chaw nruab nrab Hauv qhov tsis muaj zog, lub tshuab hluav taws xob tswj (2) yog tuav hauv lub tshuab nruab nrab. los ntawm qhov rov qab springs. Nrog rau kev tswj lub cim "V", txoj haujlwm no tsis sib haum rau txoj haujlwm hydraulic hauv nruab nrab! Thaum lub tshuab hluav taws xob valve tswj lub voj raug kaw, lub tshuab hluav taws xob tswj tau muab tso rau hauv hydraulic central txoj hauj lwm.

Lub 4/2 thiab 4/3 proportional directional li qub yog tsim los ua cov khoom siv ncaj qha hauv cov phaj tsim. Kev khiav hauj lwm yog cuam tshuam los ntawm proportional solenoids nrog central xov thiab detachable kauj. Cov solenoids yog tswj los ntawm cov khoom siv hluav taws xob sab hauv

Muaj nuj nqi: - Nrog de-energized solenoids (7 thiab 8), lub hauv paus txoj hauj lwm ntawm tus tswj spool (2) los ntawm compression springs (3 thiab 4) ntawm lub caij nplooj ntoos hlav daim hlau (5 thiab 6) - ncaj qha kev khiav hauj lwm ntawm cov tswj spool (2) los ntawm tswj lub proportional solenoid, piv txwv li solenoid "b" (8) → Tshem tawm ntawm cov tswj spool (2) mus rau sab laug proportional rau cov hluav taws xob input teeb liab → Kev sib txuas ntawm P mus rau A thiab B mus rau T ntawm orifice-type crosssections nrog cov yam ntxwv zoo ntws - Hloov tawm ntawm lub solenoid (8) → Lub caij nplooj ntoos hlav compression (3) coj cov tswj tuav (2) rov qab mus rau hauv qhov chaw nruab nrab Nyob rau hauv qhov tsis muaj zog, lub tshuab hluav taws xob tswj (2) yog tuav hauv qhov chaw nruab nrab ntawm lub tshuab. rov springs. Nrog rau kev tswj lub cim "V", txoj haujlwm no tsis sib haum rau txoj haujlwm hydraulic hauv nruab nrab! Thaum lub tshuab hluav taws xob valve tswj lub voj raug kaw, lub tshuab hluav taws xob tswj tau muab tso rau hauv hydraulic central txoj hauj lwm
