Oil sump filter, for vehicle, has inlet ports into central closing chamber closed by spacer, which is moved by inertia of vehicle to close off inlet pipes, which are not immersed in oil

摘要

The oil sump filter (10) has at least two inlets (18, 20), each of which can be closed by the closing device (22), so as to avoid the interruption of the oil flow into the filter, when the layer of oil is inclined relative to the horizontal (H). The closing device forms an axial closing chamber (28), which has an upper face (30), with an opening (32) to supply the pump, and a spherical lower face (34), with the supply inlets. An inertial spacer (36) is in contact with both faces, has an axial port (38) and is mounted to slide around to select the required oil inlet.
