Oil sump assembly with an integrated oil filter
An oil sump assembly comprises an oil sump including a first sidewall and a bottom wall for containing oil and an oil filter connected to a bottom portion of the first sidewall of the oil sump. The first sidewall includes a drain hole at the bottom portion and at least a portion of the bottom wall of the oil sump includes a slanted portion sloped towards a bottom of the first sidewall. An oil inlet and an oil outlet of the oil filter face the first sidewall of the oil sump.
1. An oil sump assembly, comprising:
an oil sump including:
a slanted bottom wall having a channel terminating in a cone-shaped portion at its lowermost point;
a sidewall attached to said slanted bottom wall and having an exterior interface with a lower drain hole in fluid communication with an interior volume of said cone-shaped portion and an upper filtered oil outlet hole extending through said interface and said sidewall, said interface being adjacent said lowermost point; and
a cylindrical oil filter connected to said sidewall at said interface with an outer wall of said cylindrical oil filter dimensionally conforming to an arc defined by said cone-shaped portion, said cylindrical oil filter having an end wall with a bottom inlet hole substantially aligned with said lower drain hole for receiving oil to be filtered and an outlet hole in fluid communication with said upper filtered oil outlet hole for returning filtered oil to an interior of said oil sump.
2. The oil sump assembly of claim 1 , further comprising:
a spigot having a hollow interior in fluid communication with said upper filtered outlet hole and protruding from said interface for insertion into said outlet hole of said cylindrical oil filter.
3. The oil sump assembly of claim 2 , wherein said outlet hole of said cylindrical oil filter has threads for threadably engaging exterior threads of said spigot.
4. The oil sump assembly of claim 1 , wherein opposing sides of said slanted bottom wall are sloped toward said channel at an upper portion of said slanted bottom wall.
5. The oil sump assembly of claim 1 , further comprising a pipe fluidically connected to said upper filtered outlet hole for delivering filtered oil to a pump.
6. The oil sump assembly of claim 1 , wherein the end wall of the cylindrical oil filter includes a plurality of inlet holes surrounding the outlet hole.
