Definitions

  • the present invention relates to an external duct of an outlet of a volute of a heat transfer fluid pump of a heat engine of a vehicle.
  • FIG. 1 shows in perspective a sectional view of a portion of a crankcase comprising a coolant pump and an outer conduit according to the embodiment of the invention
  • FIG. 2 represents a sectional view of a portion of the crankcase comprising the coolant pump and the external conduit according to the embodiment of the invention
  • This mounting cavity 14 also comprises an outlet 4 provided with an orifice of a volute 3 of a heat transfer fluid pump 2 for circulating this fluid under pressure in a cooling circuit of this engine.
  • This outlet 4 is an orifice 4 communicating with the cavity of the volute 3 of the pump 2.
  • a pump 2 is preferably arranged in a housing defined in the engine and in particular in a housing defined in the crankcase 8 and this , so as to reduce the size of the engine.
  • the volute 3 also called “high-pressure chamber” of the pump 2 is intended to receive a blade 17, or a turbine, contributing to the circulation of the fluid under pressure in the cooling circuit.
  • This blade 17 is mounted on one end 16 of a pump shaft passing on either side of a pump body (not shown).
  • This volute 3 is formed in the crankcase 8 and comprises in a intermediate portion, arranged for example substantially in line with the pump shaft a feed inlet (not shown) provided with an orifice for allowing the supply of the pump 2 of the engine heat transfer fluid.
  • this cylinder block 8 also comprises an external duct 1 of the outlet 4 of the volute 3 of the pump 2 which is fixed on the outer face 9 of this casing 8.
  • This external duct 1 can be a removable part which is attached to the outer face 9.
  • the outer conduit 1 comprises first and second components 5a, 5b which can be two separate parts which are assembled / connected to each other sealingly. In an alternative, these first and second components 5a, 5b may together form a single piece.
  • This external duct 1 is arranged in the mounting cavity 14 by being mechanically and sealingly connected to the outer face 9 of the cylinder block 8. This mechanical connection is made from a cooperation between fastening elements including elements
  • the connecting zone 10 is preferably defined at a peripheral edge of this mounting cavity 14.
  • the first component 5a of this external duct 1 is capable of guiding the heat-transfer fluid from the outlet 4 of the volute 3 of the pump 2 to the inlet 6 of the internal circuit 7 comprising the internal supply duct 15 formed by at least a cooling chamber. More precisely, the first component 5a forms, with the external face 9 of the casing 8 and in particular with the mounting cavity 14, the second channel 1 1b for circulating the heat-transfer fluid towards this inlet 6 of the internal circuit 7.
  • the first component 5a of this external conduit 1 comprises a passage zone 12 of the heat transfer fluid of the second channel 1 1b to the first channel 1 1 a.
  • This passage zone 12 is preferably comprised of a part of this first component 5a that can be defined equidistant from the ends 24a, 24b of this component 5a visible in FIG. 2.
  • This passage zone 12 is provided by openings 13 visible in FIG. a cross-section of the passage zone 12 of Figure 3 which is essentially in the form of an inverted "U".
  • the passage zone 12 comprises side walls 23 which each comprise an opening 13. These openings 13 participate in the passage of the heat transfer fluid from the second channel 1 1b to the first channel 1 1 a.
  • this crankcase 8 when the pump 2 circulates the heat transfer fluid in the cooling circuit, the fluid is then discharged from the pump 2 via the outlet 4 of the volute 3 to circulate under pressure in the second channel 1 1 b in the direction of the arrows referenced 20. While circulating in this second channel 1 1 b, this fluid is then led to both the internal circuit 7 defined in the crankcase 8 via the inlet 6, and to at least one device of the cooling circuit by passing through the passage zone 12, in particular the openings 13 defined in this zone 12 in the direction of the arrows referenced 21.
