The invention relates to a normally closed hydraulic valve and a brake system using the same. A two-way normally closed valve ("NC valve") includes a housing having a first NC valve passage and a second NC valve passage in fluid communication with a central bore. The armature is disposed for selective longitudinal reciprocation relative to the central bore between a first armature position and a second armature position. A valve seat is positioned within the central bore in selective fluid communication with the NC valve first passage and the NC valve second passage. A poppet valve is at least partially positioned within the housing and longitudinally interposed between the armature and the valve seat. The poppet valve remains at least partially in engagement with the armature and is thereby carried for selective longitudinal reciprocation relative to the valve seat between a first poppet valve position and a second poppet valve position. The poppet valve cooperatively defines a two-way valve structure with the valve seat.
本发明涉及常闭液压阀及使用该常闭液压阀的制动系统。双向常闭阀(“NC阀”)包括壳体,该壳体具有与中心孔流体连通的NC阀第一通道和NC阀第二通道。电枢设置成相对于中心孔在第一电枢位置和第二电枢位置之间选择性纵向往复运动。阀座定位在中心孔内,与NC阀第一通道和NC阀第二通道选择性流体连通。提升阀至少部分地定位在壳体内,并在纵向上插在电枢与阀座之间。提升阀至少部分地保持与电枢接合,并由此被承载,用于相对于阀座在第一提升阀位置和第二提升阀位置之间选择性纵向往复运动。提升阀与阀座协作地限定双向阀结构。
