Integrated electrical feed pump e.g. internal gear pump used in motor vehicle, has cover which is fixed axially and radially with respect to the housing, arranged with recess

摘要

#CMT# #/CMT# The electrical feed pump (7) has a rotor (3) and a stator (1) which are arranged in housing (23). The rotor is slidingly mounted in the stator. A cover (11) provided between components is fixed axially and radially with respect to the housing. A recess (33) is formed in the cover. The axial-thrust bearing (17) is intended in the center of the cover, which is connected with the gear (19). The rotor is provided with an outer ring (37) in which permanent solenoids (21) are arranged. #CMT# : #/CMT# An independent claim is included for method for establishing electrical feed pump. #CMT#USE : #/CMT# Integrated electrical feed pump such as internal gear pump (claimed) used in motor vehicle. #CMT#ADVANTAGE : #/CMT# The maintenance operation of the electrical feed pump can be simplified favorably with simple installation process. The cover can be adjusted axially and radially with respect to housing. The twist of the cap with respect to housing can be prevented. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an exploded perspective view of electrical feed pump. 1 : Stator 3 : Rotor 7 : Integrated electrical feed pump 11 : Cover 17 : Axial-thrust bearing 19 : Gear 21 : Permanent solenoid 23 : Housing 33 : Recess 37 : Outer ring.
