摘要： A side thruster valve of an aerospace craft is improved to reduce torque of a servo-motor, etc. needed for nozzle opening and closing to thereby realize a compact and light weight device. The side thruster valve comprises a valve plug having its back directed to an axis of the aerospace craft and independently movable between a fully opened position and a fully closed position of the valve plug in a plane orthogonal to the axis of the aerospace craft, an actuating means for moving the valve plug in an axial direction of the valve plug and an elastic member for activating the valve plug in the axial direction of the valve plug. In a side thruster device comprising a plurality of the side thruster valves, the side thruster valves are arranged independently of each other to thereby broaden freedom of combustion control and improve fuel consumption.

摘要： A universal joint includes a first shaft member having a cylindrical portion, a pair of yoke portions at a free end thereof and a ball-like portion formed between the yoke portions and a second shaft member having a cylindrical portion and a pair of yoke portions at a free end thereof. The ball-like portion is formed integrally and inseparably with the yoke portions of the first shaft member. The first and second shaft members are thus detachably and movably connected with each other through engagement between the ball-like portion of the former and the yoke portions of the latter.
