主权项

1. An internal gear pump for a hydraulic vehicle brake system, comprising:
a cartridge which is configured to act as a housing of the internal gear pump, and which is configured to be inserted into a receptacle for the internal gear pump; wherein the internal gear pump defines a premountable subassembly that includes;
a pinion;a ring wheel; andan axial disk that is configured to laterally seal off a pump space defined by the internal gear pump, and that includes:
an inside face which bears against end faces of the pinion and of the ring wheel; andan outside face opposite said inside face and facing away from the pump space of the internal gear pump, said outside face exposed on the cartridge and defining a pressure field that communicates with a pressure connection bore of the internal gear pump, wherein the receptacle for the internal gear pump is located in a surround housing, wherein the surround housing has a second receptacle for a second internal gear pump, and wherein the internal gear pump has a common drive with the second internal gear pump.
