Abstract
Systems are provided for an oil system including a filter with a large surface area. In one example, a system may include an oil filter with a prismatic shape. This shape may include a filter surface area greater than an inlet area of an oil port and the filter surface area may also be located a distance away from the oil port.
Claims20
A variable displacement oil pump for a motor vehicle, the oil pump comprising:
- a mechanism for adjusting displacement of the pump, the mechanism including an oil port formed in an internal wall of the pump;
- a filter supported by a wall such that a filter surface area is a distance from an inlet of the oil port and wherein the filter is substantially prism shaped and includes a longitudinal slot provided within an outer surface of the prism shaped filter;
- and
- the filter is compressible by reducing a width of a longitudinal slot;
- and
- wherein the filter surface area is larger than an area of the inlet of the oil port, and wherein the filter surface area forms the outer surface of the prism shaped filter.
