YANG Guo ping (Department of Automobile and Machinery Engineering, Changsha Communications University, Changsha 410076, China)  
In this dissertation the analysis of the hydraulic rock breaker and rock drill at home and abroad leads to an return oil chamber of a new hydraulic impactor.So it solves the problem of locomotion hamper accretion at piston reversion and piston stroke.The design method of this return oil chamber is studied,and it is a valuable reference for the improvement of hydraulic impactor.
