Breather canister for crankcase

A breather canister comprising:

• an outer housing comprising a wall and a floor that cooperate to define an interior chamber, the outer housing comprising an inlet coupled to the floor and defining a first passageway;
• and
• a diffuser comprising a stem defining a second passageway, the stem being coupled with the inlet such that the first passageway of the inlet and the second passageway of the stem are in fluid communication with each other, the diffuser further comprising a cap that is coupled with the wall of the outer housing opposite the floor, and the stem extends between the cap and the floor, wherein:
• the wall of the outer housing defines a vent aperture that is in fluid communication with the interior chamber;
• the diffuser defines an upper aperture and a lower aperture that are each in fluid communication with the second passageway of the stem and the interior chamber;
• the lower aperture is more proximate the inlet than the upper aperture;
• the vent aperture defines a first centerline;
• the upper aperture defines a second centerline;
• the vent aperture and the upper aperture are offset from each other such that the first centerline and the second centerline are not coaxial;
• and
• the stem defines a third centerline and each of the first centerline and the second centerline intersect the third centerline.

A compressor comprising:

• a piston and a crankshaft that cooperate to generate pressurized air;
• a crankcase that houses the piston and the crankshaft;
• and
• a breather canister coupled to an exhaust port of the crankshaft, the breather canister comprising:
• an outer housing comprising a wall and a floor that cooperate to define an interior chamber, the outer housing comprising an inlet coupled to the floor and defining a first passageway;
• and
• a diffuser comprising a stem defining a second passageway, the stem being coupled with the inlet such that the first passageway of the inlet and the second passageway of the stem are in fluid communication with each other, wherein:
• the wall of the outer housing defines a vent aperture that is in fluid communication with the interior chamber;
• the diffuser defines an upper aperture and a lower aperture that are each in fluid communication with the second passageway of the stem and the interior chamber;
• the lower aperture is more proximate the inlet than the upper aperture;
• the vent aperture defines a first centerline;
• the upper aperture defines a second centerline;
• and
• the vent aperture and the upper aperture are offset from each other such that the first centerline and the second centerline are not coaxial.
