SOLENOID VALVE DEVICE

WIPO Patent Application WO/1997/015936

A1

A solenoid valve device, in which a valve actuating unit comprising valve constitutional parts installed in a valve housing having a guide cylinder is mounted on a base body, and the front end of the guide cylinder and the housing main body are magnetically coupled by means of a magnetic path forming frame encompassing the coil on a bobbin. A coil unit, in which the bobbin with coil is buried in a synthetic resin molded portion, is mounted on the base body. The magnetic path forming frame has at one end an engagement hole in which the front end of the guide cylinder is fitted and at the other end is in contact with the housing body. The magnetic path forming frame is mounted on the parts of the molded portion corresponding to the coil so that the guide cylinders are loosely inserted into the center hole of the bobbin. Thus a magnetic path is established reliably by the magnetic path forming frame, and the assembly of the coil, the bobbin and the magnetic path forming frame onto the valve actuating unit is facilitated.
