Abstract
In order to enable efficient operation and reliable heat dissipation in a transmission, a pumping device () for lowering the internal pressure in a transmission () is equipped with a suction line (), which leads from a suction point () on a connection side () to a discharge point () on a discharge side (), a pump () for generating negative pressure at the suction point (), a pump drive () for driving the pump (), and an oil separator () connected upstream or downstream of the pump () in the suction line () that separates oil contained in the suction flow and returns it via a return line () to the connection side (), and a check valve () connected downstream, preferably directly downstream, of the pump (). A transmission () with such a pumping device (), a use of a pumping device () and a method for reducing power losses in a transmission () are disclosed.
