Definitions

  • the present invention relates to a cover for the lubricating-oil sump of an internal-combustion engine of the kind defined in the preamble of Claim 1.
  • US-A-5 130 014 discloses a cover of this kind, associated with a deep pan section designed as a removable oil container.
  • US-A-3 590 955 discloses a cover for an oil pan, wherein float valves are associated with the oil drain openings.
  • an internal combustion engine for a motor vehicle is generally indicated 1.
  • the engine comprises a block 2 in which the drive shaft 3, the associated pistons, and other members and devices are mounted in a known arrangement.
  • a sump 4 for the lubricating oil is connected to the bottom of the block 2.
  • An intake pipe 5 extends into the sump 4 and is connected, known manner, to the intake of a lubricating-oil circulation pump (not shown).
  • a cover, generally indicated 7, is fixed to the oil sump 4 by means of screws 6.
  • This cover is advantageously made of moulded plastics material.
  • the cover 7 is of a generally dished shape and has, in its central region, an integral tubular element 8 inside which the intake pipe 5 extends.
  • the tubular element 8 is of a length such that it extends beyond the lower end of the intake pipe 5.
  • the lower portion 8a of the tubular element 8 is flared like a bell and an annular retaining member 9 snap-engaged thereon clamps and holds a filter element 10 in position.
  • the portion of the intake pipe 5 which extends in the tubular element 8 of the cover 7 advantageously carries an external sealing ring 11 which bears on the inner surface of the element, closing the annular space between this element and the intake pipe in a leaktight manner.
  • the cover 7 is fixed to the sump 4 and the sump is then coupled and fixed to the block 2 in which the lubricating-oil circulation pump is already mounted.
  • the end portion of the lubricating-oil intake pipe 5 is introduced into the tubular element 8 of the cover 7 on the end portion of which the filter 10 is already mounted.
  • the base of the cover 7 advantageously has a plurality of holes 12 of which one is visible in Figure 2 in which the sump 4 is shown sectioned in a plane disposed behind the plane of the section shown in Figure 1.
  • the holes 12 in question are advantageously located in relative positions corresponding to those of the cylinders of the engine.
  • each shutter 13 is substantially in the form of a door articulated like a rocker to the face of the cover facing the sump 4, about an axis or fulcrum 14.
  • the shutters 13 are formed and connected to the cover 7 in a manner such that they can be arranged by gravity in a rest position, shown in broken outline in Figure 2, in which they leave the associated holes 12 clear. In this condition, lubricating oil can descend from the block 2 to the sump 4 in operation.
  • the arrangement of the shutters 13 is such that they can be urged dynamically to a working position shown in continuous outline in the drawings, as a result of movements of the oil in the sump 4 back towards the cover 7.
  • the lubricating oil is prevented from returning from the sump 4 towards the engine block 2 so that the intake pipe 5 of the oil pump safely continues to be "dipped” in the oil held in the sump.
  • the filter 10 is preassembled directly on the end of the intake pipe 5 connected to the oil-circulation pump.
  • the edge of this large hole and the intake pipe define an annular duct through which a considerable amount of oil can return from the sump to the region above the cover as a result of jolting, with the danger that the circulation pump may take in oil mixed with air.
