Abstract
A hydrostatic servo assembly unit () for being arranged inside, outside or distant from a variable displacement hydrostatic unit () and for controlling the displacement of the variable displacement hydrostatic unit (). The servo assembly unit () includes a servo housing () in which at least one servo piston () is arranged. The piston head () of the servo piston () can be pressurized such that the servo piston () can move linear relative to a servo cylinder () formed in the servo housing (). The servo assembly unit () further includes a movable output element () protruding outside of the servo housing (), which can be mechanically coupled to a displacement element () of a variable displacement hydrostatic unit ().
