Abstract: The present invention relates to a impact body for a hydraulic impact device and, more specifically, to a impact body for a hydraulic impact device which is capable of remarkably reducing production costs by inserting a cylinder liner having a flow path into an inner wall of a body, adjusting an impact interval and an impact strength according to the properties of a material to be crushed by adjusting an impact distance of a piston, minimizing the loss of a fluid in a pipe by forming a cylindrical flow path between the body and the cylinder liner, and remarkably improving performance by employing a circular valve to shorten the flow path whereby reduction of pressure is minimized.
