Claims

[Scope of utility model registration request]

a valve body having an inflow port and an outflow port and forming an inner hole through which these ports open; a control spool that changes a passage opening area between both ports; a spring that biases the control spool in a direction to close a passage communicating between both the ports; and a spring that is disposed coaxially with the control spool on the valve body. and a solenoid wound around the outer periphery of the yoke to which a control current is applied, so that the axial displacement of the control spool is brought about by the attractive force of the yoke generated in response to the current applied to the solenoid. In the electromagnetic proportional control valve, the control spool is connected to a first spool made of a magnetic material that is attracted to the yoke through which lines of magnetic force from the solenoid pass, and a second spool made of a magnetic material that controls a passage opening area between the two ports. 1. An electromagnetic proportional control valve characterized in that the spool is divided into a spool, and both spools are integrally connected via a partition member made of a non-magnetic material.
