Booster

 

a device for increasing fluid pressure; it consists of two interconnected cylinders (see Figure 1).

Figure 1. Hydraulic booster: (1) small-diameter plunger, (2) large-diameter piston, (3) working fluid

In the low-pressure cylinder of a booster there is a piston of large diameter D connected to a plunger of small diameter d in the high-pressure cylinder. The resultant pressure ph, will be (D2/d2) times greater than the initial pressure pi (a factor of 40–60). Boosters, mainly of the hydraulic type, have limited use in modern hydraulic presses (to increase the compression force) and in pneumatic-hydraulic amplifiers (in multiple-point clamping devices for machine tools).
