Abstract
A housing support for a hydraulic displacement unit swashplate wherein the swashplate extends across the split line between a two-part housing for the hydraulic displacement unit. The housing support is provided by a support surface formed on one housing part and which has extensions thereof extending beyond the housing part. These extensions protrude into the other housing part when the two housing parts are assembled together at the abutting split line. These surface extensions are preferably in the form of a pair of fingers which are spaced from each other to straddle a bearing positioned in a bearing cavity formed in the two housing parts. This enables the fingers to be of sufficient structural section to withstand the hydraulic forces imposed on the part of the swashplate supported thereby.
