Air to Hydraulic Reciprocating Booster

Like other Miller Boosters, Reciprocating Boosters offer the convenience of intensified hydraulic output from shop air input, but with more output volume for operation of larger cylinders or multiple cylinders. 

The operation is completely automatic, supplying a continuous (though pulsating) flow during cycling until the boost ratio is attained. 

At that point, the booster stalls until the output pressure drops. 

While the booster is stalled output pressure is maintained without heat generation or air consumption, an important feature for any holding operation.

The Reciprocating Booster consists of a double rod end air cylinder with a hydraulic pressure chamber at each end. 

Thus it delivers fluid output in both directions. the unit has built-in 3-way pilot valve at each end of cylinder. 

These valves are operated by the piston at the end of the stroke and provide the air signal needed to shift the power valves used to reciprocate the booster.
