PURPOSE: A hammer driven with water is provided to prevent damages from occurring by operating while supplying high water pressure to an upper and lower position of a piston. CONSTITUTION: A hammer driven with water comprises a back head(2), a buffer ring(4), a ring(3), a pipe(5), a valve cap(6), a valve spring(7), a valve(8), a valve housing(9), a housing inner(10), a piston, a piston bush, and a bit ring. Water is injected into an inner hollow unit of the piston and flows out after being injected into a vertical fluid path when the piston is located in a lower end. The water fills in the space between the piston and a wear sleeve after being injected into the vertical fluid path when the piston is located in the center. The water flows in a horizontal hole and fills the space between the valve spring and the valve when the piston is located at the upper end. |
