Abstract

A pump includes a cam plate, and an input shaft for rotationally driving the cam plate. A pump housing at least partially surrounds the cam plate and defines a cam plate oil reservoir around at least a portion of the cam plate. A bearing support is at least partially disposed within the cam plate oil reservoir. The bearing support defines a bearing oil reservoir at least partially surrounding a portion of the input shaft. At least one passage extends between the bearing oil reservoir and the cam plate oil reservoir. Dynamic motion imparted on oil within the cam plate oil reservoir facilitates migration of oil from the cam plate oil reservoir through a bearing at least partially supported by the bearing support into the bearing oil reservoir and through the at least one passage into the cam plate oil reservoir.
