Novel sleeve valve type hydraulic impacting mechanism

The invention relates to a novel sleeve valve type hydraulic impacting mechanism which comprises a piston, a cylinder body, a sleeve valve, a single-way element and a sealing element. The piston and the sleeve valve are arranged in serial. Piston moving is controlled through the sleeve valve. The piston feeds back pressure signals to a valve element of the sleeve valve. The piston and the valve element of the sleeve valve move in a reciprocating mode, so that the piston obtains high impacting frequency and large impacting force. The mechanism is small in mounting size, a limited space is fully used, compared with a common sleeve valve type structure, the number of parts is small, a sleeve valve body and the valve are easy to machine, and mounting is easy and practical. The mechanism can adjust impacting frequency and impacting work by adjusting input flow and input pressure, and the signal hole position and the stroke are adjusted.
