Abstract
An axial piston hydraulic device. The device has a housing that uses a servo piston in order to control the displacement of a swashplate within the device. By using a servo member disposed within a cavity of an end cap on the housing the axial piston hydraulic device is able to provide three operating positions depending on the angle of the swashplate.
