Claims

[Claims for Utility Model Registration] 1. An input port and an output port that communicate with each other via a valve chamber, and a first
A main valve partitioning the valve chamber into a second valve chamber on the opposite side of the input port and the output port, a pilot valve provided in the second valve chamber opposite to the main valve, and the pilot valve. The solenoid section is provided in the first valve chamber on the output port side, and is opened and closed by the connection and separation of the main valve, and when opened, the fluid pressure on the input port side is applied to the output port side. A first valve hole for outflow is formed in the main valve, and is opened and closed by connecting and separating the pilot valve, and when opened, fluid pressure on the second valve chamber side is discharged to the output port side. a second valve hole;
a communication path that communicates the input port side and the second valve chamber side, and the fluid pressure on the second valve chamber side is discharged from the second valve hole and the pressure on the second valve chamber side is reduced. , a solenoid valve in which the main valve is separated from the first valve hole and the first valve hole is opened, the cross-sectional area of the communication passage regulating the flow rate is variable, and the first valve hole is closed. A solenoid valve characterized in that a cross-sectional area of the communication passage when the first valve hole is opened is larger than a cross-sectional area of the communication passage when the first valve hole is opened. 2. The communication passage is provided in a large-diameter communication hole provided in the main valve and an opening/closing means for opening and closing this communication hole, and is connected to the large-diameter communication hole by displacement when the main valve opens and closes. 2. The electromagnetic valve according to claim 1, wherein the communication passage is formed by a small-diameter communication hole that is coupled to and released from the coupling, and the cross-sectional area of the communication passage is variable. 3. The communication passage is formed between a large-diameter communication hole opened in the main valve, an opening of the communication hole, and a shielding wall facing the opening, and 2. The electromagnetic valve according to claim 1, wherein the communication passage has a variable cross-sectional area formed by a gap whose width changes according to displacement.
