A hydraulic breaker with a auto lubrication structure
The present invention relates to a hydraulic breaker having a structure for automatically supplying lubricating oil, wherein the structure for automatically supplying lubricating oil can be simplified and compact in the hydraulic breaker without additional external components by directly using the oil pressure of operating oil. The structure for automatically supplying lubricating oil comprises a first finishing member, a second finishing member, a pumping spool, a first chamber, a second chamber, an operating oil supply passage, a lubricating oil discharge passage, and a check valve.
본 발명은 별도의 외장부품 없이 유압 브레이커의 내부에서 작동유의 유압력을 직접적으로 이용하여 윤활유를 자동적으로 공급하는 구조를 간단하면서도 컴팩트화한 윤활유 자동공급구조가 내장된 유압 브레이커에 관한 것이다.
