Abstract
An active flush regulation system having a rotary component, a stationary component, one or more biasing elements for applying a biasing force to the stationary component in a first direction for biasing together a rotor sealing surface and a stator sealing surface, and a holder component for holding one or more of the stationary component and the rotary component. The rotor sealing surface and the stator sealing surface form an under-balanced seal face, where in a first closed position the rotor sealing surface and the stationary sealing surface contact each other, and when flushing fluid is introduced to the seal face, the flushing fluid acts to place the rotor sealing surface and the stator sealing surface in an open position where the rotor sealing surface and the stator sealing surface are separated from each other to form a gap to allow the flushing fluid to pass therealong.
