| 摘要 |
The present invention relates to a valve set (50) having a flat plate type spool driven by incompressible hydraulic oil and a striking body (1) for a hydraulic striking apparatus. All the conventional control valves pass hydraulic oil through a through hole, formed on a cylindrical wall, from the inside to the outside or from the outside to the inside using a cylindrical spool and cause much energy loss while passing the hydraulic oil though multiple cylinders. The present invention relates to a flat plate type valve set (50) reducing fluid flow energy loss by forming the spool (20) and a valve body (30) in a flat plate shape and reducing the number of parts and a volume by forming a rectangular line fluid passageway. In addition, the present invention relates to the hydraulic striking apparatus enhancing energy efficiency using the valve set (50) to increase striking energy. |
