ABSTRACT:
A swash plate apparatus is provided for use in connection with the axial pistons of a rotatable cylinder block in a hydraulic device to modify the output of the cylinder block. The swash plate includes a first trunnion member extending in a first direction from the swash plate and a second member extending from the swash plate in a second direction, where the second direction is generally perpendicular to the first direction. The second member terminates in an arc segment forming a bearing surface to engage a bearing in the housing.
