- An annular web 59 integrally formed with the housing 50 in a depression 61 is plastically pressed by contacting the screw head 53 a and makes one separate sealing ring unnecessary.
- the screw torque is based on the crankcase or on the lead frame, but not on the housing 50. This means that no independent occurs Dissolve by creeping the housing material.
- the clip connectors 54 shown in detail in FIGS. 11 and 12 can be used in addition to the Fastening eyes 52 or be provided instead.
- the clip connector 54 includes a hook-shaped element 55, which is attached to the housing 50 via an elastic arm 57 is. When pushed onto the web 32, the hook-shaped element 55 engages around the Web 32, as shown in Figure 12, and thus secures the housing 50 in a predetermined Position below the crankcase. An inserted sealing cord 72 seals the housing 50 on a circumferential bearing surface on the web 32 against the interior of the surrounding oil pan.
- the clip connections 54 have the advantage that they are the same can be removed again simply and quickly, as previously by "clipping on" the housing 50 were manufactured.
- the capsule device 49 can also be closed again quickly and easily disassemble, for example for later maintenance or repair work.
- Fig. 13 shows the lid 56 with sieve 62 in an enlarged view in a view from the Crankcase side.
- the screen 62 is preferably tilted at a predetermined angle arranged to the oil pan or to the oil sump contained in it, so that the Pump oil pumped through sieve 62 along sieve 62 along an enlarged sieve area must overcome. In this way, the extracted oil is freed of air bubbles that build up on it separate the screen 62.
- the capsule device 49 advantageously prevents the rotating ones from “splashing" Counter shaft 20 in the oil sump, which leads to an undesirable foaming of the oil and unnecessary loss of work.
- the suction snorkel integrated in the capsule device 49 58 for the oil pump reduces the total number of parts when assembling the Internal combustion engine.
- the capsule device 49 for example, only takes on the auxiliary shaft 20 oil extracted for their lubrication and the oil flowing out of the crank mechanism becomes of such an embodiment completely past the auxiliary shaft 20 into the oil pan directed.
