Claims

[Scope of Claim for Utility Model Registration] A two-stage flow rate solenoid valve having the following configuration conditions A, B, C, D, E, F, and G. A. In the valve body 1, the inlet side and the outlet side of the main flow path 2 having the first valve body 3 in the intermediate portion are communicated by a bypass 5; B. A pressure chamber is provided behind the first valve body 3. 4, C. A second valve body 6 is provided in the middle part of the bypass 5 to open and close the bypass 5 at the bypass seat 5a; D. A first and second valve body 6 for operating the first and second valve bodies 3, 6 Two electromagnetic means 7, 8 are provided in the valve body 1, and the first and second plungers 7a, 8a of the first and second electromagnetic means 7, 8 operate on the same axis and share a common guide cylinder 7b.
be contained within. E The inlet side of the main channel 2 and the pressure chamber 4 are communicated through a through hole, and the pressure chamber 4 and the bypass 5 are communicated through a small passage 10 provided in the valve body 1,
The outlet side 10b of the small passage 10 is opened on the front side of the bypass seat 5a in the bypass 5; forming a pilot passage for the first valve body 3 when opened; G the first valve body 3 is opened by the operation of both electromagnetic means 7 and 8; the second valve body 6 is opened by the operation of the first electromagnetic means 7; It must be
