Abstract

Described herein is a pump assembly (I), particularly for fuel injection systems of air-compressing, auto-igniting internal combustion engines, having a high-pressure pump (2), which has a high-pressure pump shaft (71, and a gear pump (3). In an embodi$ni dUN 2012 coupling (12) is provided between the high-pressure pump shaft (7) and the gear pump shaft (8) of the gear pump (3) or a gear (10) of the gear pump (3), which has at least one sacrificial surface (2 1,22).
