Abstract

An oil pump for a motor vehicle, in particular an electrically operated gear pump, contains a pump housing that is closed relative to an end side by a housing cover, a shaft which extends in a longitudinal direction and to which a pump wheel is secured. The shaft is mounted on a first bearing and on a second bearing on both sides of the pump wheel. A pressure chamber is formed on a pressure side, and a lubricant channel leads from the pressure chamber to the shaft in a region of the first bearing for the lubrication of the two bearings. Between the shaft and the pump wheel secured to the shaft, at least one longitudinal channel also leads along the pump wheel to the second bearing.
