キ倍力装置の電磁弁。[Scope of claim for utility model registration] Provided in the valve body of the brake booster,
When the solenoid is deenergized, the valve means is moved away from the valve seat by a spring to open a fluid passage communicating the variable pressure chamber and the constant pressure chamber of the brake booster via the valve mechanism, and the solenoid is energized. At the same time, the valve means is seated on the valve seat to close the fluid passage, and fluid pressure on the variable pressure chamber side is applied to the valve means to press it against the valve seat. The solenoid valve is a solenoid valve, wherein the spring and the valve means are connected to each other by a seat portion on the outer periphery that is seated on the valve seat, and a communication passage communicating with the fluid passageway on the inner periphery, and when the solenoid is deenergized, a ring-shaped first valve body that is unseated from the valve seat by a first spring; and a ring-shaped first valve body that is interlocked with a plunger that is moved forward and backward by the solenoid and is seated on the first valve body when the solenoid is energized. At the same time, the first valve body is seated on the valve seat against the first spring to close the fluid passage, and when the solenoid is deenergized, the valve seat is closed by the second spring. a poppet-shaped second valve body that is separated from the first valve body seated on the valve body; Features a solenoid valve for the brake booster.
