1,010,669. Fatigue testing of flexible tubes. REGIE NATIONALE USINES RENAULT. July 5, 1962 [July 7,1961], No. 25890/62. Heading GI5. Flexible fluid-filled tubes 20, such as are used in hydraulic braking systems, are fatigue tested by securing one end to a fixed fluid inlet 21 and the other to a fluid connection 19 carried on an eccentrically-rotated spindle 10, Fig. 1. The spindle 10 carries a bar 15 to which several tubes may be connected for simultaneous testing, and rotates about its own axis with the same angular velocity as, but in the opposite direction to, a driven hollow flywheel 2. This is brought about through a chain-and-sprocket connection with a fixed sprocket 17 housed within the flywheel 2. The spindle 10 and sprocket 13, mounted in a slidable socket 9, maintain their relative occentation so that the tubes do not become twisted as the flywheel rotates. Connecting elements 22 for the fixed ends of the tubes are slidably housed in a fixed part 21 of the apparatus and may be locked after adjustment by screws 23. Each blind connection 19 has a bleed nipple 25.
