ADJUSTABLE VIBRATION GENERATOR Russian patent published in 2004 - IPC

FIELD: vibration equipment, generators of low frequency oscillations.

SUBSTANCE: the invention presents an adjustable vibration generator and is dealt with the field of generators of low frequency oscillations. The technical result - an increased reliability of the vibration generator at the expense of simplification of its design. To achieve the given result the design of the vibration generator provides, that in the lower part of the unbalance there is a rod with the piston or a pair of the cylinders located inside the shaft perpendicularly to its axis of rotation. The cylinders have cavities filled in with a liquid and connected to each other by a pipeline with a capability to control the liquid consumption. At that the unbalance is made with an initial radius shifted in respect to the center of mass.

EFFECT: the invention allows to increase reliability of the vibration generator.
