Abstract
A regulator apparatus for distributing a fluid may include a charging valve assembly and a flow multiplier assembly. In a recharge mode, a valve of the charging valve assembly is in an open position, and the fluid is received in a second cylinder of the flow multiplier assembly, causing first and second pistons of the flow multiplier assembly to move in a first direction. In a purge mode, the valve is in the seated position, and the fluid is received in a first cylinder of the flow multiplier assembly, causing the first and second pistons to move in a second direction, and discharging an outlet flow through an outlet of the flow multiplier assembly. The second cylinder may have a bore cross sectional area that is greater than a bore cross sectional area of the first cylinder. Apparatuses disclosed herein may be implemented in a circumferential sampling tool.
