SOLENOID VALVE

摘要

A solenoid valve capable of providing a high controllability with reduced hysteresis of control pressure by reducing a sliding resistance of a valve disc, wherein, because a steel ball (11) is provided between a rod (6) and a spool (13) and a contact surface (13a) of the spool (13) in contact with the steel ball (11) is provided on a flat plane vertical relative to the moving direction of the spool (13), a load applied from the steel ball (11) is transmitted normally relative to a contact part of the steel ball (11), i.e., vertically (i.e., axially) relative to the flat plane of the contact surface (13a) of the spool (13), whereby, even if the rod (6) is inclined, a moment to tilt the spool (13), which occurred before, is not produced and a load is transmitted vertically (i.e., axially) relative to the flat plane of the contact surface (13a) of the spool (13) and, therefore, the sliding resistance of the spool (13) can be suppressed and the hysteresis of the control pressure can be reduced.
