| Abstract | A vibration or reciprocating hydraulically driven impact tool for breaking up paving, compacting soil, or similar construction purposes. The tool employs a piston situated in a housing and configured to form (in cooperation with the housing) three chambers. One of the chambers is filled with a compressed gas which acts as a shock absorber/spring, with the other two chambers serving to drive adjacent flanges of the piston in opposite directions to provide reciprocating action. The device is constructed so that when no mechanical force is applied to the handle, the piston is at rest in its forward position (being urged there by the compressed gas), with the hydraulic forces acting upon the piston shoulders being balanced. When the handle is pushed forward, the hydralic system is altered so that unbalanced forces act on the piston flanges, causing the piston to start moving. Thereafter, a hydraulic valve system provides the desired reciprocating motion of the piston. |
