    摘要： Hydraulically driven percussion device, comprising a piston reciprocally movable within a body and striking against a tool, said piston defining with reference to the body two cylinder spaces, one of which continuously communicates with the high pressure duct and the other by the aid of a distribution means alternatingly connectable to the high pressure duct and the low pressure duct. At both ends of the piston there are breathing chambers opening into the free atmosphere. Within one of said two cylinder spaces a sleeve-like distribution means has been placed to encircle the piston and which distribution means, in order to move into a position such that movement of the piston directed towards the tool becomes possible, is controlled by means of grooves provided in the piston and in the body when the piston is in its end position farthest removed from the tool and only on condition that the pressure in the high pressure duct exceeds a pressure set with an adjustable valve incorporated in the body.

    摘要： This invention relates to a compressed-air pump which has a compressed-air motor and operates with compressed air and has a cylinder and a cooperating block or head therefor. A piston moves forward and backward in the cylinder space. The supply of compressed air to the motor is controlled by a valve movable between first and second positions in a bore of the block. The block is formed with passageways for supplying compressed air to the piston when it is in one position in the cylinder space and the valve body is in its first position, and for terminating such supply of compressed air when the valve body moves to its second position responsive to the supply of compressed air. In the second position of the valve body communication is established between the cylinder space and the atmosphere. In order to reduce malfunction of the compressed-air motor all of the compressed air supply passageways are formed in the block and the valve body is characterized by the absence of passageways.
