Claims

[Scope of utility model registration request]

(1) First and second cylindrical fixed cores coaxially provided inside the front and rear of a cylindrical case made of magnetic material, and first and second electromagnetic coils respectively wound around both fixed cores. a substantially cylindrical valve housing having a base fixed to the front end of the case by the case and the center axis, having an outer inlet in the distal partition wall and an outer outlet in the side wall; the valve housing and a first fixing member; A cylindrical first tube is inserted into the iron core so as to be slidable in the axial direction, and has an inner inlet having a smaller area than the outer inlet in the center of the distal partition wall provided with an annular valve, and an inner outlet in the side wall. An on-off valve, a first movable iron core fixed to the outer periphery of the rear end of the first on-off valve at a position facing the rear end of the first fixed iron core with a certain gap in between, and a rod-shaped front half with a valve at its tip. A second on-off valve is inserted into the cylinder of the first on-off valve so as to be able to slide in the axial direction. It consists of a fixed second movable core, and a stopper that is provided in the middle of the case and abuts the first and second movable cores, each of which is pressed by a spring member, and selectively acts on the first and second electromagnetic coils. A multi-stage operating solenoid valve that performs zero flow, medium flow, and maximum flow operations when energized.

(2) The multi-stage operating solenoid valve according to claim 1, wherein the outer and inner inflow ports are provided with jets for controlling flow rate metering.
