rexroth電磁(ci)閥同(tong)時依靠(kao)介(jie)質壓力，主(zhu)副(fu)閥得(de)以緊密關閉。常開電磁(ci)閥，
rexroth電磁(ci)閥線圈通(tong)電後(hou)由於吸力作用(yong)，動(dong)鐵(tie)芯(xin)下(xia)移(yi)，把副(fu)閥閥塞壓下(xia)，
rexroth電磁(ci)閥減少了(le)作用(yong)在(zai)主(zhu)閥閥杯(bei)上(shang)的壓(ya)力，
rexroth電磁(ci)閥當(dang)主(zhu)閥閥杯(bei)上(shang)的壓(ya)力減少到(dao)壹定(ding)值(zhi)時，
rexroth電磁(ci)閥利用(yong)壓(ya)差把主(zhu)閥閥杯(bei)推起(qi).
