  • Patent number: 4481835
    Abstract: A hydraulic adjusting system is provided for the continuous adjustment of the vibration amplitude of a rotating eccentric element. The hydraulic adjusting device includes a piston in a single acting cylinder. A piston connecting rod extends through the cylinder and is rigidly journalled axially inside the piston. One end of the rod is rigidly connected to a drive shaft of the eccentric element and the other end to a power source for rotatably driving the eccentric element. The system provides for continuous adjustment of amplitude vibration and, since the vibration amplitude is directly proportional to the hydraulic pressure acting on the piston, the system also facilitates setting and monitoring of such vibration amplitude.
