Claims20
A filter assembly for filtering liquid, comprising:
- a filter housing including a cap, a bowl, and an enclosed space, a lower circumferential surface of the cap affixed to an upper circumferential surface of the bowl to form the enclosed space, the cap including a fluid inlet port, a fluid outlet port, and a gas venting port for the enclosed space, and the bowl including slots disposed on an inner side of the bowl;
- and
- a filter cartridge disposed in the enclosed space of the filter housing and fluidly connected to the fluid inlet port and the fluid outlet port in the cap, and the filter cartridge including radial projections disposed in the slots of the bowl blocking rotation of the filter cartridge relative to the bowl and preventing a bottom and a side of the filter cartridge from contacting the bowl, wherein:
- the cap includes a first connection ridge that extends from a bottom of the cap and surrounds each of the fluid inlet port and the fluid outlet port in the cap;
- the filter cartridge includes a top with a cartridge inlet, a cartridge outlet, and a second connection ridge that extends from the top of the filter cartridge and surrounds each of the cartridge inlet and the cartridge outlet in the filter cartridge, and the first connection ridge of the cap being affixed to the second connection ridge of the filter cartridge;
- and
- the second connection ridge includes:
- a first ridge portion that surrounds the cartridge inlet;
- a second ridge portion that extends from the first ridge portion and surrounds the cartridge outlet;
- and
- a third ridge portion and a fourth ridge portion, and each of the second ridge portion, the third ridge portion, and the fourth ridge portion extends outward from the first portion in a different radial direction.
