Abstract
An oil filter for vehicle lubrication system includes a housing forming a cavity, a filter medium mounted in the housing cavity, an inlet port located upstream of the filter medium in the direction of oil flow, a first outlet port located downstream of the filter medium. The oil filter includes a second outlet port located downstream of the filter medium.
Claims10
An oil filter for a vehicle lubrication system comprising:
- a housing having at least one side wall extending between a base and a top wall defining a cavity;
- a first conduit axially extending through the cavity defining a first outlet port at an end thereof, a first portion of the first conduit adjacent to the first outlet port defining a perforated zone;
- a second conduit laterally extending through the cavity, and being orthogonally connected with the first conduit within the cavity at an end of the second conduit, such that an interior volume of the first conduit is in fluid communication with an interior volume of the second conduit, the opposing end of the second conduit extending through the at least one side wall and defining a second outlet port;
- a filter media surrounds the perforated zone;
- and
- an inlet for introducing oil to be filtered upstream of the filter media;
- wherein, oil to be filtered enters the housing through the inlet, flows through the filter media, through the perforated zone, and filtered oil flows out of the housing through the first outlet port and the second outlet port.

A lubrication circuit of a motor vehicle comprising:
- an oil filter for a vehicle lubrication system including:
- a housing having at least one side wall extending between a base and a top wall defining a cavity;
- a first conduit axially extending through the cavity defining a first outlet port at an end thereof, a first portion of the first conduit adjacent to the first outlet port defining a perforated zone;
- a second conduit laterally extending through the cavity, and being orthogonally connected with the first conduit within the cavity at an end of the second conduit, such that an interior volume of the first conduit is in fluid communication with an interior volume of the second conduit, the opposing end of the second conduit extending through the at least one side wall and defining a second outlet port;
- a filter media surrounding the perforated zone;
- and
- an inlet for introducing oil to be filtered upstream of the filter media;
- wherein, oil to be filtered enters the housing through the inlet, flows through the filter media, through the perforated zone, and filtered oil flows out of the housing through the first outlet port and the second outlet port;
- a pump;
- a heat exchanger for cooling the oil of the lubrication circuit;
- and
- a by-pass circuit permitting bypass of the heat exchanger.
