Abstract

The aim of the invention is to provide an oil pump that is both light and compact. To this end, the inventive oil pump comprises a housing consisting of a material containing aluminium, and mobile moulded parts are arranged in said housing. Said mobile moulded parts are at least partially produced from a sinterable material comprising at least one austenitic iron-base alloy, and the mobile moulded parts produced from the sinterable material have a heat coefficient corresponding to at least 60 % of that of the housing.
