Abstract
Abstract An oil guiding housing is arranged below the crankcase of an internal-combustion engine and has a storage tank for lubricating oil and a housing part with a connection for an oil filter. In the pan part of the oil guiding housing situated directly below the crankshaft, a forward flow and return flow part for lubricating oil is integrated. The oil guiding housing ensures a targeted guiding of all lubricating oil flows and provides a good degassing of the oil.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
146 words
An oil guiding housing for an internal-combustion engine having a crankcase, a crankshaft, a crank space and integrated return flow ducts for lubricating oil flowing back from cylinder heads, comprising means for detachably fastening the housing to a flange of the crankcase, a pan part extending approximately parallel with respect to the crankshaft and which bounds the crank space adjacent tot eh crankshaft, and a forward flow device and a return flow device for lubricating oil arranged in the pan part and extending separately from one another so as to lead into a storage tank for lubricating oil which is held on the end side of the pan part and is separated therefrom by a bottom of the pan part, wherein a single inlet opening for the oil is arranged in the bottom of the pan part approximately in the center and above the storage tank.
Claim 2
Dependent Claim
146 words
An oil guiding housing for an internal-combustion engine having a crankcase, a crankshaft, a crank space and integrated return flow ducts for lubricating oil flowing back from cylinder heads, comprising means for detachably fastening the housing to a flange of the crankcase, a pan part extending approximately parallel with respect to the crankshaft and which bounds the crank space adjacent tot eh crankshaft, and a forward flow device and a return flow device for lubricating oil arranged in the pan part and extending separately from one another so as to lead into a storage tank for lubricating oil which is held on the end side of the pan part and is separated therefrom by a bottom of the pan part, wherein a single inlet opening for the oil is arranged in the bottom of the pan part approximately in the center and above the storage tank.
Claim 3
Dependent Claim

Claim 6
Dependent Claim
34 words
The housing according to claim 1, wherein in the pan part, the return flow device comprises a first groove and a second groove between which is arranged the forward flow device comprising a tube.
Claim 7
Dependent Claim
46 words
The housing according to claim 5, wherein below a plane bounding the pan part and at the end side of the pan part, a housing part is operatively arranged having a flange surface for an oil filter and is operatively connected to the forward flow device.
Claim 8
Dependent Claim
39 words
The housing according to claim 2, wherein the grooves are bounded to the bottom, by exterior side walls of the pan part and by interior longitudinal webs having notches in a transverse plane (Q) adjacent to the inlet opening.
Claim 9
Dependent Claim
46 words
The housing according to claim 7, wherein below a plane bounding the pan part and at the end side of the pan part, a housing part is operatively arranged having a flange surface for an oil filter and is operatively connected to the forward flow device.
Claim 10
Dependent Claim
55 words
The housing according to claim 7, wherein the bottom essentially slopes downwardly from the front end of the oil guiding housing to the discharge opening, and ascends from there to a rear end of the pan part, and the bottom bounds a collecting area between the grooves in the center section of the pan part.
Claim 11
Dependent Claim
43 words
The housing according to claim 2, wherein the second groove is partially covered by a rib arranged in the crankcase and follows approximately a figure eight-shaped connecting rod contour, and the opposite first groove is closed off by a wall by the crankcase.
Claim 12
Dependent Claim
45 words
The housing according to claim 10, wherein below a plane bounding the pan part at the end side of the pan part, a housing part is operatively arranged having a flange surface for an oil filter and is operatively connected to the forward flow device.
Claim 13
Dependent Claim
39 words
The housing according to claim 1, wherein the grooves are bounded by the bottom, by exterior side walls of the pan part and by interior longitudinal webs having notches in a transverse plane (Q) adjacent to the inlet opening.
Claim 14
Dependent Claim
55 words
