Abstract:
A pressure controlling device for a vehicle comprising: a first unit having an electronic circuit portion provided in a housing, a plurality of electromagnetic coil portions and a conductive connecting member for electrically connecting these, a second unit having a plurality of valve bodies and a network of pressure paths, wherein the plurality of valve bodies in the second unit are protruded to be inserted in the first unit respectively, wherein the electromagnetic coil portion are composed of a bobbin around which a coil is wound, an upper yoke and a lower yoke each provided around the bobbin and forming a magnetic path, an elastic object provided between the lower yoke and the bobbin and a means for contacting the bobbin to a part of the housing for restricting movement of the bobbin;wherein a first unit includes a coil housing for accommodating a plurality of magnetic coil portions, an intermediate member having an electronic circuit portion and provided in the coil housing and a cover for covering the intermediate member; and a conductive connecting member including a first contact portion for connection to the electronic circuit portion and a second contact portion for connecting to the plurality of electromagnetic coil portions is provided in the coil housing; and bobbins in the plurality of electromagnetic coil portions are constructed so as to be in contact with a part of the coil housing;wherein electromagnetic coil portions includes an upper yoke and a lower yoke both provided in a bobbin around which a coil is wound interposing a gap; a part of housing is interposed between the upper yoke and the bobbin; an elastic object is interposed between the lower yoke and the bobbin; and the bobbin is engaged by both of the yokes so as to be in contact with a part of the housing so that both of the yokes can play in the gap with respect to the housing when a valve body is inserted; andwherein the electronic circuit portion is electrically connected to connector portion, connectable with the outside, by arranging the electronic circuit portion and the connector portion and interposing a gap between the electronic circuit portion and the connector portion; and the electronic circuit portion is fixed to a housing such that at least a part of the electronic circuit portion apart from a position connected with the connector portion or a position connected with the first contact portion is flexibly engaged with the housing.
