4.0 Product Information –[cont’d] 

 

 

The breaker is equipped with an accumulator. 
The accumulator is a self-contained pressure 
vessel with an expansible chamber divided by a 
flexible membrane. The gas-side chamber is pre-
charged with nitrogen gas (N2), while the oil-side 
chamber is for receiving, storing and discharging 
pressurized oil. 

 

 

As the piston nears the top of its stroke, signal 
ports inside the cylinder become pressurized and 
shift the operating valve. Oil is blocked from 
exiting the upper end of the cylinder. The valve 
directs oil to the upper end of the cylinder and the 
oil becomes pressurized. 

 

 

Pressurized oil supplied by the pump and 
combined with the discharged oil from the 
accumulator drive the piston downward until it 
impacts the tool. 

 

 

The cycle is continuous until the machine 
operator releases the momentary switch 
controlling the ON/OFF valve.
