摘要： In a proportional solenoid valve, a solenoid main body includes a coil, a valve seat member having a seat portion, a valve element that is displaced in accordance with a current applied to the coil so as to be brought into and out of contact with the seat portion, and a valve guide portion that is arranged coaxially with the seat portion and guides the displacement of the valve element. The housing is attached to the solenoid main body so that a space is formed between the housing and the valve seat member. A seal member made of an elastic material is provided in the space between the housing and the valve seat member.

摘要： In a proportional solenoid valve, a valve drive portion that includes a coil, a core that is excited by application of a current to the coil, a plunger that is displaced by a magnetic attraction force generated by the excited core, and a spring that biases the plunger in a direction in which a distance to the core is increased. The spring is set so that a space is maintained between the plunger and an attraction surface of the core when the spring is fully compressed.

摘要： A bleed-type proportional electromagnetic valve having an input port, output port, and ejection port is disclosed. Fluid force and pressing force, proportionate to an output pressure and a current flowing in a solenoid coil respectively, act on a bleed valve for controlling the output pressure, whereby the valve can obtain an output pressure commensurate to the flowing current by displacing the valve to a position that those forces counterbalance, wherein the valve is provided with a stop valve disposed so as to be in sliding contact with a passage between the input and output port, and in contact with or separated from a valve seat. This enable the stop valve to contact with the valve seat so as to close the input port and communicate the output port with the ejection port when controlling the output pressure to be minimum.
