Abstract

Official abstract text for this publication.

A hydraulic fluid transfer coupling has a stator, a first coaxial rotor, and a second coaxial rotor. The first rotor is radially inwards of the stator, the second rotor is radially outwards of the stator, at least part of the first rotor axially overlapping with the stator, and at least part of the second rotor axially overlapping with the stator. The first rotor carries one or more first rotating fluid lines, and the second rotor carries one or more second rotating fluid lines. The stator carries one or more first static fluid lines and second static fluid lines. Each pair of a first rotating fluid line and the corresponding first static fluid line are fluidly coupled and each pair of a second rotating fluid line and the corresponding second static fluid line are fluidly coupled. Hydraulic fluid is transferable between each static fluid line and the corresponding rotating fluid line.

First claim

Opening claim text (preview).

The invention claimed is: 1. A hydraulic fluid transfer coupling having a stator, a first coaxial rotor rotatable about the stator, and a second coaxial rotor rotatable about the stator, the first rotor being radially inwards of the stator, the second rotor being radially outwards of the stator, at least part of the first rotor axially overlapping with the stator across a first rotary interface, and at least part of the second rotor axially overlapping with the stator across a seco…
