Claims

[Scope of utility model registration request]

a first comprising a first input port and a first output port;
a second body having a second input port and a second output port; a first body formed in the first and second bodies and communicating between the first input and output ports and between the second input and output ports; A second fluid passage, an outer yoke made of a magnetic material fixed to one end of both bodies, an inner core disposed on the axis of the outer yoke, and a non-magnetic material inserted and fixed to the outer periphery of the inner core. a bobbin, a solenoid coil wound on the bobbin and forming a magnetic circuit together with the outer circumferential yoke and the inner core when energized; a first valve body provided in the solenoid coil and attracted to the inner core when the solenoid coil is energized; a second valve body made of a non-magnetic material disposed in the second body on the other end surface of the inner core and coaxially opposed to the inner core;
a rod that is slidably inserted into the inner hole of the inner core and that can protrude so that both ends abut against the first and second valve bodies; a rod that is provided on the inner core and is formed between the rod and the inner core; an atmospheric port that communicates with a third fluid passage that can communicate with the second fluid passage; one end of which is locked to the inner core;
It has a first spring that biases the valve body in the closing direction and a second spring that has one end latched to the second body and biases the second valve body in the open direction, A third valve body is built in so as to be relatively displaceable and is biased to abut the bent portion by a third spring stretched in the hollow part, and when the solenoid coil is energized, the first and second valve bodies are A solenoid valve characterized in that it is interlocked via the rod.
