ABSTRACT:
A percussive device for creating impact impulses, which device comprises a housing accommodating a striker. The striker has a tail portion located in a power cylinder which is joined to the housing and is filled with a fluid medium under pressure, said fluid medium operating the striker. Provision is made of an arresting mechanism which is kinematically connected to a drive designed to engage the striker for effecting its backward stroke in the process of which the fluid medium under pressure is compressed, storing potential energy. According to the invention, the striker backward stroke drive is constructed in the form of several hydraulic cylinders equidistantly spaced round the periphery of the housing. The rod of each of the hydraulic cylinders is connected to the striker arresting mechanism. One of the spaces in said hydraulic cylinders is constantly connected with the interior space of the power cylinder for the purpose of moving the arresting mechanism under the pressure of the fluid medium, whereas the other cylinder space is periodically put in communication with the pressure source, in order to effect the backward stroke of the arresting mechanism together with the striker, and with a pressure medium exhaust line.
