ABSTRACT:
An arrangement of the suction funnel of a lubricating oil pump in the oil pan of an internal combustion engine, in which the suction funnel is supported at the bottom of the oil pan by means of an elastic spacer member and the interior space of the suction funnel is in sealed connection with the interior space of the hollow spacer member; the spacer member rests with its lower end on the bottom of the oil pan by means of a bead-like, relatively inelastic support rim which is provided with one or several openings, the spacer member directly surrounds the inlet end of the suction funnel with prestress by means of its part disposed in the upper half thereof and constructed of larger diameter than the lower half in such a manner that a screen filter arranged in the suction funnel is force-lockingly and form-lockingly clamped with its retaining rim clamped between the inlet end of the suction funnel and the part at the upper half of the spacer member.
