Claims (1)
イロツトバルブ２を介しタンクポート３に連通す
る油通路中に、タンクポート３方向への油流通を
阻止する逆止弁４であつて他のソレノイド５の励
磁により開放される逆止弁４を挿入設置したこと
を特徴とする電磁比例圧力制御弁。 A check valve 4 is provided in an oil passage communicating with a tank port 3 through a pilot valve 2 which changes and controls the set oil pressure by a solenoid 1, and prevents oil flow in the direction of the tank port 3 by energizing another solenoid 5. An electromagnetic proportional pressure control valve characterized in that a check valve 4 that is opened is inserted and installed.
