A variable shroud-to-static gap with protrusions and grooves cuts impeller leakage and fluid shear, lowering heat and power demand.
A divided upper-lower chamber reservoir uses vortex flow to vent gas bubbles, sustain hydraulic circulation, and absorb volume changes.
An unvented chamber separates entrained air in the damper oil supply, damping pressure oscillations and reducing Campbell crossing resonance.
A vent valve and restrictor release tank pressure during engine shutdown while preserving positive oil reservoir pressure at high altitude.
Distributed subsea drains remove liquid along pipeline gradients to cut holdup and pressure loss while keeping pigging continuous.
An annular tank with dividing walls, degassing partitions, and integrated cooling cuts installation space while improving oil cooling and air removal.
A cyclone deaerator placed before the oil filter removes gas bubbles in hydraulic tanks, reducing cavitation risk and flow disturbances.
