Abstract
A device for varying the displacement of a variable displacement bent axis unit includes a one-piece yoke having a bucket portion adapted to carry a cylinder block kit of the bent axis unit, a trunnion bearing portion for swing control on one side of the bucket portion, and a trunnion portion for fluid porting on the other side of the bucket portion. The bucket portion has a bottom wall, a continuous side wall, and an open top. Inside the yoke is a pair of fluid passages intersecting the interior of the bucket portion and extending separately and entirely within the bottom wall and the side wall before opening onto the trunnion portion for fluid porting.
