Claims

[Scope of utility model registration request]

A movable valve seat, in which a first valve port communicating with a first outlet is formed, is slidably fitted into one end of a valve chamber formed in the body, and the movable valve seat is attached to one end of the valve chamber by a biasing spring. The first valve is biased to move toward the end side and abut against an abutment provided in the valve chamber, and a second valve port communicating with the second outlet is provided at the other end side of the valve chamber. an inflow port is formed in the body and is concentric with the port and opens into the valve chamber between the abutment position of the movable valve seat and the second valve port, and the body is provided with an inlet port on the first valve port side. A sliding hole communicating with the outside is formed concentrically with the first valve port and the second valve port, and the valve stem is inserted into the valve chamber by tightly fitting into the sliding hole. A first valve body corresponding to the movable valve seat on the front side in the biasing direction and a second valve body corresponding to the second valve mouth are attached to the first valve opening, and the valve stem is attached to the front side of the movable valve seat in the urging direction. An electric actuator is attached to the body for sliding the valve stem in the axial direction, and the first valve body is moved toward and away from the movable valve seat by sliding the valve stem in the axial direction.
opening and closing the valve port, and changing the distance between the second valve body and the second valve port while keeping the first valve port closed to change the opening degree of the second valve port. An electric three-way valve characterized by having an adjustable configuration.
