<p>#CMT# #/CMT# The pump has an electromotor (4) provided with a stator (13) and a pump unit (5), where the pump unit is provided with internal gears (22), external gears (24) and a housing pot. A holding pin i.e. retaining ring, fastens the external gears at the stator. The stator, the internal gears and the external gears are secured with a work area or a plate in the housing pot. The external gears are provided with permanent magnets (17), where the external gears are secured at the stator and in the housing pot caused by magnetic forces produced by the permanent magnets. #CMT# : #/CMT# An independent claim is also included for a method for manufacturing a pump assembly. #CMT#USE : #/CMT# Upstream electrical supply pump for conveying fuel from a fuel tank into a low pressure input of a fuel high pressure pump of a pump assembly of a motor car. #CMT#ADVANTAGE : #/CMT# The external gears are secured at the stator and in the housing pot caused by the magnetic forces produced by the permanent magnets, so that components required for the pump can be reduced, thus manufacturing a pump assembly of a motor car with compact structure. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of an upstream electrical supply pump. 4 : Electromotor 5 : Pump unit 13 : Stator 17 : Permanent magnets 22 : Internal gears 24 : External gears.</p> |
