Abstract

A hydraulic breaker for absorbing and reducing vibration and noise generated from the breaker and for reducing debris and dust scattered from the impact tool during using the breaker is provided. Space between main body of the breaker and outer housing is filled with fluid supplied from outside of the outer housing. Fluid hose is connected to a fluid hole formed on the outer housing to supply fluid into the space. Upper absorber is disposed between a bracket and upper portion of the main body, lower absorber is disposed between front cover of the outer housing and front head portion of the main body. Side absorbers are disposed between sidewall of the outer housing and outer cylindrical sidewall of the main body to keep a distance between outer housing and main body and to provide the space filled with fluid. Fluid, such as water, filled in the space is ejected through holes formed on the front cover of the outer housing. The ejected water prevents debris and dust generated during operation of the breaker from being scattered.
