The present invention relates to a valve set (50) having a flat and plate-shaped spool operated by an incompressible hydraulic oil, and a hammering body (1) for a hydraulic hammering apparatus, and relates to: a flat and plate-shaped valve set (50) having a spool (20) and a valve body (30) formed to be flat and in a plate shape so as to reduce the number of parts and the volume thereof, and having a square linear fluid passage formed so as to reduce the loss of fluid flow energy, whereas all conventional control valves use a cylindrical spool such that a large amount of energy is lost while hydraulic oil passes through a through-hole formed on a cylindrical wall body from the inside thereof to the outside thereof and vice versa, and also passes through several cylinders; a hydraulic hammering apparatus for increasing hammering energy by using the valve set (50) so as to improve energy efficiency. |
