摘要： A guide body for an electromagnetic valve device is provided. The device includes a coil assembly surrounding the guide body, a plunger driven by magnetic force and slidably disposed inside the guide body. The guide body slidably guides the plunger in an open/close direction of the valve body along a guide face thereof. The guide body includes a first nonmagnetic section that supports a pole body and a part of the plunger at which the pole body and the plunger oppose each other, a second nonmagnetic section that supports the valve body, and extends at least throughout a sliding range of the valve body, and a magnetic section intermediate the first and second sections so that a portion of the lines of magnetic force passes therethrough. The guide face is formed so as to coaxially support the plunger and the valve body displaceable in the open/close direction.

摘要： A pressure compensated electromagnetic proportional directional flow control valve of the present invention integrally includes: an electromagnetic proportional directional flow control valve configured to be driven by a solenoid; and a pressure compensated valve configured to carry out pressure compensation of a flow rate controlled by the electromagnetic proportional directional flow control valve. A pressure compensation spool moves so as to balance forces of a spring, a first pressure chamber, and a second pressure chamber. With this, the pressure compensation for maintaining a constant pressure difference between an upstream side and a downstream side of a first variable aperture can be carried out, and a surplus liquid of a liquid flowing from a liquid-pressure supply port to a derivation port can flow out from a branch port to outside.

摘要： Provided is a configuration in which: a spool driven by an electromagnetic proportional solenoid is urged by a spool-returning spring configured to exert urging force in an opposite direction to a driving direction of the electromagnetic proportional solenoid; a mechanical stopper is disposed at the stroke end of the spool; current dither causes a control current to micro-vibrate, the control current driving the electromagnetic proportional solenoid; and the mechanical stopper includes a stopper-urging spring configured to allow the spool to vibrate owing to the current dither even when the spool is in contact with the mechanical stopper. A proportional solenoid control valve with this configuration is capable of reducing hysteresis at the stroke end of the spool by means of the current dither, and controlling the spool in a stable manner over the entire control range including the stroke end of the spool.
