IMPACT BODY FOR HYDRAULIC IMPACT DEVICE

摘要

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.

主权项

1. A hitting body 1 for a general hydraulic stroke device having a body 100, a piston 50 formed at the inside of the body 100, and an upper body 20 formed on the upper portion of the body 100 comprising:
a cylinder liner 200 inserted into and formed at the inside of the body 100; at least one operating flow path hole 210 and return flow path hole 270 formed at a wall of the cylinder liner 200 respectively; and a circular valve 230 formed between the seal retainers 240, which are formed at the upper end thereof.
