Fluid delivery system for supplying fluid to a machine assembly

A fluid delivery system for supplying fluid to at least one machine assembly which is an engine and/or transmission of a motor vehicle and is arranged in a machine assembly housing, comprises:

• a. a pump module comprising a first pump and a second pump for delivering the fluid;
• b. a drive comprising an electric motor for driving the pump module;
• and
• c. a housing, which comprises a reservoir for storing the fluid, a first housing part, and a second housing part, and which is separate from the machine assembly housing,
• d. wherein the reservoir comprises at least one aspiration point, and
• e. the pump module comprises a first inlet, a second inlet, a first outlet and a second outlet, and
• f. wherein the first inlet is fluidically connected to the reservoir via a first suction conduit, and the first outlet is fluidically connected to the machine assembly via a first pressure conduit, and
• g. the second inlet is fluidically connected to the housing via a second suction conduit, and the second outlet is fluidically connected to the reservoir via a second pressure conduit,
• h. wherein the first pressure conduit and the second pressure conduit are formed completely or partially between the first housing part and the second housing part, such that the first housing part and the second housing part define walls of the first pressure conduit along at least a same axial portion of the first pressure conduit, and define walls of the second pressure conduit along at least a same axial portion of the second pressure conduit,
• i. wherein the first housing part and/or the second housing comprise/comprises channel portions which are open towards the end face of the respective housing part, and which form the first pressure conduit or portions of the first pressure conduit or respectively the second pressure conduit or portions of the second pressure conduit when the two housing parts are joined,
• j. wherein the first pump and/or the second pump is/are formed by a rotary pump, and a rotor of the first pump and a rotor of the second pump are arranged on a drive shaft of the drive, and
• k. wherein the housing comprises at least a first return opening, via which the fluid can flow back from the machine assembly into the reservoir, and a second return opening via which the fluid can flow back from the machine assembly or another machine assembly into the housing, and wherein the first return opening and/or the second return opening comprise(s) a screen on its/their side which faces the machine assembly.
