FIELD: instrument making.
SUBSTANCE: volume booster for drive system mainly includes an adjustable limiter, so that the device output power may be adjusted for a specific application. Feed path operates to allow fluid supply to force time of drive switch in the drive system, for example, in the direction of opening. Exhaust path operates to provide back pressure relief, for example, when the drive system switches the drive in closing direction. Limiter is placed in the output line and is selectively manipulated between a plurality of positions for setting plurality of certain output power values, thus excluding any requirement for replacement of complete volume booster for obtaining other values of output power.
EFFECT: device includes a housing, a feed line, an output line, and a limiter.
