An axial piston pump and an axial piston motor, mounted in a housing each have a rotating element and a non-rotating element. Each non-rotating element is mounted for tilting movement about axes transverse to the axes of rotation of the rotating element, on trunnions in its own respective pair of mounting journals in the housing for controlling the transmission ratio. The pump and the motor are disposed side-by-side in the housing with the axes of rotation approximately parallel to each other. A stationary manifold, fixed to the housing, has surfaces in contact with the rotating pump element and the rotating motor element. Fluid passages open in the surfaces in fluid communication with the pump and motor cylinders through a pump/manifold interface. Internal fluid passages in the stationary manifold convey fluid pressurized in the pump directly to the motor, and convey spent fluid displaced from the motor back to the pump. |
