Definitions
- the invention relates to a fluid guide for an internal combustion engine according to the features mentioned in the preamble of claim 1.
- Such a liquid guide is known from DE 25 02 034 A1.
- it is considered disadvantageous to arrange an oil pump and a front cover as individual parts on the internal combustion engine housing, since when the oil is pumped from the oil pump into the channels of the front cover, the connection between the two is difficult to seal and oil leakage occurs.
- this document suggests a common housing for the oil pump and front cover.
- the invention has for its object to achieve a secure seal for the liquid with a generic liquid guide even with a separate design of the liquid pump and the front cover.
- the liquid pump and the front cover are designed as individual parts with the advantages of separate interchangeability and the possibility of using different liquid pumps without the necessity of a seal which is difficult to implement directly between the liquid pump and the front cover.
- the tunnel-like connection within the internal combustion engine housing between the liquid pump and the cover channel allows separate, easy-to-seal separating surfaces of the liquid pump and the front cover with the internal combustion engine housing, which run alongside one another transversely above this tunnel-like connection.
- the embodiment according to claim 2 enables a particularly cost-effective interchangeability of a coolant pump, since only the movable parts exposed to wear and the pump housing part carrying them are designed separately from the machine housing.
- Coolant for cooling an internal combustion engine is conveyed by a pump wheel 1 of a coolant pump 2, which is driven via a pulley 3 and is mounted in a pump housing cover 4 by means of a shaft 5.
- the coolant pump 2 is designed in a spiral construction with a spiral channel 7 located in the machine housing 6 of the internal combustion engine, which is covered by the pump housing cover 4, which is screwed onto the front of the machine housing 6.
- the coolant is conveyed out of the spiral duct 7 into a cover duct 8, which is formed by the machine housing 6 and an end cover 9 screwed to the end face of the latter.
- a cover duct 8 which is formed by the machine housing 6 and an end cover 9 screwed to the end face of the latter.
- an oil cooler 10 screwed onto the end cover 9 and partially protruding into the front-side machine housing 6, is arranged for cooling lubricating oil by the coolant, which is then guided from the oil cooler 10 into a longitudinal channel 11 and to the individual cylinders 12 in the machine housing 6.
- Spiral channel 7 and cover channel 8 are hydraulically connected to one another by a connecting channel 13, which lies inside the machine housing 6 in a tunnel-like manner.
- the connecting duct 13 is delimited by a wall part 14 as part of the machine housing 6, which carries the mutually separated sealing surfaces 15, 16 both for the pump housing cover 4 and for the end cover 9. This avoids a difficult seal to be realized between the pump housing cover 4 and the end cover 9, at the same time the pump housing cover 4 together with the pump wheel 1 can be easily replaced.
- the mouth 17 of the connecting channel 13 in the cover channel 8 lies approximately in the parting plane 18 between the machine housing 6 and the end cover 9.
- the flow in this area is determined by a curved rib 19 of the machine housing 6 deflected so that the flow direction in the region of the mouth 17 is approximately perpendicular to the parting plane 18 and thus a short circuit flow in the longitudinal channel 11 is largely prevented.
- the coolant then flows through the oil cooler 10 with two deflections, partly in its longitudinal and partly in its transverse direction, so that a good cooling effect is ensured in the latter.
