Hydraulic intensifiers, hydraulic – hydraulic

Hydraulic intensifiers increase hydraulic pressure by a fixed ratio. 

With this method it is possible, e.g. to use a low-pressure

machine hydraulic system for consumers that can profitably 

benefit from a pressure that is multiple higher.

The intensification is achieved by means of a fixed ratio between two

pistons surface areas. That means that the secondary pressure can

be controlled by means of the primary supply pressure.

Once the adjusted default min. pressure in the integrated sequence

valve is reached, the intensifier piston is activated and the operating

pressure in the system increases by a factor of 3.85. With this the oil

amount is of minor importance.

Another advantage is that there is no oscillatory piston movement

required in the intensifier. Thus, the susceptibility to wear of

components is reduced. Also a higher outlet pressure is

immediately available.
