Device (1) for pressure regulation in an oil pump (2), having a regulating piston (4) and having a control valve (5), wherein at least two pressure levels can be regulated by means of the regulating piston (4), wherein the regulating piston (4) has a first active face (6) and a second active face (7), wherein an oil pressure acts on the first active face (6), wherein by means of the control valve (5) it is possible to open and close a control duct in order to make the oil pressure act on the second active face (7). By means of the regulating piston (4), it is possible to open and close a bypass (18), wherein the bypass (18) connects a pressure side (19) of the oil pump (2) to a suction side (20) of the oil pump (2). |
