<p>The invention relates to a control valve unit (9) for an adjusting device of a hydrostatic piston engine. The control valve unit (9) comprises a valve housing (34), in which a valve element can bemoved in a longitudinal direction. The valve element can be adjusted from a neutral position into a first end position and an opposite second end position. Along with an increasing adjustment of the valve element, a first or second outlet connection (35a, 35b) is connected in an increasing manner to an inlet connection (12). The other respective outlet connection (35b, 35a) is connected simultaneously to a relief line (13).
