摘要 |
The device has a hydraulic actuator with a piston, and a cylinder (30) with high pressure hydraulic pump (32). The piston is secured to control and synchronization ring in which off-center wrist pins are fixed in blade roots. A hydraulic fluid from the pump is fed to the piston via channel (34).
