HYDRAULIC HAMMER
The invention relates to the mining and construction industry and is directed toward increasing the operating efficiency and reliability of a hydraulic hammer by increasing heat transfer (cooling) and lowering the temperature both of the hydraulic hammer as a whole and of a liner thereof without complicating the structure of the hydraulic hammer. This technical result is achieved in a hydraulic hammer consisting of a housing having a pressure port and a drain port and having a liner disposed in said housing that has a pressure groove and a pressure port, a head that is disposed inside of the liner such that it can move reciprocally and that interacts with a working instrument, and a pressure line and a drain line, moreover, on the outer surface of the liner, there are annular grooves and two longitudinal canals, said canals being diametrically opposite one another.
