  • Hydraulic adjustment device
    Patent number: 5466121
    Abstract: A hydraulic adjustment device for variable-pitch propellers of turbo-engines comprise a shaft for driving the variable-pitch propeller. A plurality of transmission elements for feeding and draining, as well as for guiding a hydraulic fluid is disposed in the shaft. A rotation passage for the hydraulic fluid is disposed in a chamber, which surrounds the shaft. The chamber is disposed adjacent to the variable-pitch propeller and is in fluid communication with a transport medium. The hydraulic fluid is harmonious to the transport medium.
