    • The invention relates to a regulator device (1) for a hydraulic pump which pumps into at least one working pipe (13), and to a valve unit for said pump. The pumping volume of the hydraulic pump (1) is regulated with the aid of a regulator device (15, 19) exposed to a regulating pressure which is regulated by an adjusting valve (26) in conformity to a first and a second pressure. The first pressure passes through a first pressure pipe (38) and acts on a first measuring surface, the second pressure passes through a second pressure pipe (39) and acts on a second pressure surface opposite to the first surface of the adjusting valve (26), the first pressure being higher than the second pressure. Said invention is characterized in that a pressure chamber (45) is arranged between the first and second measuring surfaces, thereby forming a discharge channel towards the second pressure pipe (39).
