Definitions

  • the invention relates to an oil collecting device and an oil pump for a Internal combustion engine according to the features of the preambles of the main claims.
  • the object of the invention is therefore to provide means by means of which Oil pump sucked air is separated before the lubricating oil to consumers is fed.
  • the means for air separation should be space-saving and designed in this way be that the oil sump forming in the oil guide housing the functionality of the Air separator not affected.
  • the lubricating oil can escape from the pressure chamber, and through the Drain the oil pump housing into the first oil collection chamber.
  • the lubricating oil remains sufficient time for defoaming, so that the gas content of the lubricating oil when it is in the Oil sump is already significantly reduced.
  • the opening monitored by the valve body also flows into the trough-shaped border.
  • the double pump has two pump stages designed as gear pairs, the first pump stage is provided to supply the consumer, while the second Pump stage the oil extracted from the rear oil collection chamber in the front Oil collection space returns.
  • the oil collecting housing shown in Fig. 1, hereinafter referred to as oil pan 2 is in the assembled state with its flange surface 4 on a flange surface 6 Crankcase lower part 8, a so-called bedplate, attached.
  • a lubricating oil pump 10 designed as a double pump attached.
  • a first oil collecting space 12 is formed, in which the oil required for the supply of lubricating oil accumulates in an oil sump.
  • an oil snorkel 14 is arranged over a first Oil suction line 16 to a suction side of a first pump stage 18 of the double oil pump 10 leads.
  • a second, rear oil collecting space 20 is formed in the oil pan 2 the lowest point of which is also an oil snorkel 22, which is connected to a second one Oil suction line 24 with a suction side of a second pump stage 26 of the oil pump 10 connected is.
  • a plastic insert 28 is inserted, the two Separates oil collection spaces 12 and 20.
  • the insert 28 serves as an oil barrier and also prevents the lubricating oil from running out when driving uphill the first oil collection chamber 12 in the crank chamber and / or in the second Oil collecting space 20 can cross.
  • the lubricating oil is in the second oil collecting space 20 from the rear main bearings or connecting rod bearings of the crankshaft, which are not directly in the reaches the first oil collection chamber 12, collected and via the second oil suction line 24 pumped back into the first oil collection space 12; similarly the lubricating oil from the Spray nozzles, not shown, for piston cooling.
  • the lubricating oil pump 10 consisting of two pump stages points in the first Pump stage 18 in a known manner two intermeshing gear wheels 30 and 32 which separate the pump stage 18 into a suction side 34 and a pressure side 36 split off.
  • the first pump stage 18 has a pressure outlet 38 through which the Consumers of the internal combustion engine, such as. B. main or connecting rod bearings with lubricating oil be supplied.
  • the second pump stage 26 there are also two inside each other Intermeshing gears 40 and 42 are arranged, which also pump stage 26 in one Separate suction side 44 and a pressure side 46.
  • the housing of the oil pump 10 is constructed in three parts and consists of a basic housing 10a and two am Basic housing attached cover elements 10b and 10c.
  • the top of the The base housing 10a has an opening 48 which is in contact with the pressure side 46 of the second Pump stage 26 is connected.
  • the opening 48 has a tub-like border 50 enclosed, which forms a kind of riser 51.
  • a pressure relief valve 54 is monitored on the top of the basic housing 10a of the oil pump 10 .
  • the valve body 56 indicates known Open the opening 52 when the one created by the first pump stage 18 Oil pressure reaches a specified maximum pressure. If the opening 52 through the Valve body 56 released, then a part of the through the first pump stage 18th pumped lubricating oil also in the riser 51, from where it is after a certain Time also passes over the border 50 of the riser 51 and in the first Oil collection chamber 12 arrives.
  • the two drive gears 30, 40 of the two pump stages 18 and 26 are over a sprocket 58, which in turn has a chain drive with a not shown Crankshaft gear is connected, driven.
  • a turbocharger suction pump 60 At the front of the oil pan 2 is further flanged a turbocharger suction pump 60, which is also via the Chain gear 58 is driven.
  • a driver 62 is on the chain gear 58 provided that in the drive shaft of the suction pump 60 not shown intervenes.
  • the insert 28 is connected to two side parts 64 and 66, in which Oil return openings 68 are arranged. That in the two side parts 64 and 66 arranged oil return openings 68 each open into one, not shown Oil collection channel, both of which open below the oil level in the oil sump, whereby It is ensured that the lubricating oil is consumed by the consumer despite the Crankshaft and piston movements quickly caused pressure pulsations in the first oil collection chamber 12 returned.
