Claims

[Scope of utility model registration request]

A first valve chamber located on one end side of the flapper valve member and communicating with the fluid supply port is provided inside a valve housing that accommodates a sleeve valve member and a flapper valve member disposed inside the sleeve valve member, and a first valve chamber that communicates with the fluid supply port, and the flapper valve member. a second valve chamber located on the other end side and communicating with the fluid discharge port and communicating with the first valve chamber through the flapper valve member, the torsion bar connecting the two valve members; The operation causes the two valve members to rotate relative to each other to throttle the fluid flowing from the first valve chamber to the second valve chamber, and supplies the fluid from the first valve chamber to the fluid pressure operated device, and the fluid pressure operated device. In the flapper type servo valve device configured to discharge fluid from the second valve chamber through the second valve chamber, the servo valve device includes a blocking member that blocks off the second valve chamber and the fluid discharge port at the other end of the flapper valve member. Install it facing the side with a specified gap,
A flapper type servo valve device, characterized in that the second valve chamber and the fluid discharge port are communicated with each other through a communication hole formed in the blocking member in the axial direction of the flapper valve member.
