CONTROLLED VALVE AND AIRCRAFT WITH CONTROLLED VALVE

Title:

CONTROLLED VALVE AND AIRCRAFT WITH CONTROLLED VALVE

Document Type and Number:

Japanese Patent JPH0257769

Kind Code:

A

Abstract:

PURPOSE: To provide a controlled valve reducing required space and weight without making a structure fragile and weak by automatically opening the valve by a positioning device when the pressure difference between both faces of the valve exceeds the threshold.

CONSTITUTION: A controlled valve opens/closes a wall 1 by a flap 3. This opening/closing is controlled by a positioning device 30 with arms 34, 35. The arm 35 is placed at the edge 15 of an arm 5, and the arm 34 is placed at the edge 14 of a support 4. A computer 130 controls the controlled valve 29 according to a pressure signal detected by a sensor 131.
