Abstract
A fluid filtration system includes a filter receiver located in a fluid reservoir housing and a replaceable filter module adapted to mount in the filter receiver. Fluid to be filtered is exposed to a filter media included in the filter module and mounted in a filter chamber provided in the filter receiver. The filtered fluid is discharged into a fluid reservoir located in the fluid reservoir housing and outside the filter receiver. Low-pressure fluid is then pumped from the fluid reservoir to a fluid user and fluid discharged from the filter user is conducted to the filter chamber for filtration in the filter media.
Claims17
A fluid filtration system comprising
- a fluid reservoir housing formed to include an interior region and a filler port configured to conduct fluid to the interior region,
- a filter receiver arranged to extend into the interior region of the fluid reservoir housing, the filter receiver being formed to include a filter chamber and filter module-receiving aperture opening into the filter chamber, a fluid inlet port configured to admit unfiltered fluid into the filter chamber, and a fluid outlet port configured to discharge filtered fluid from the filter chamber into a fluid reservoir provided in the interior region of the fluid reservoir housing,
- a filter module including a filter media and a connector coupled to the filter media and configured to mate with the filter receiver at the filter module-receiving aperture to expose the filter media to unfiltered fluid passing through the filter chamber from the fluid inlet port toward the fluid outlet port to produce a stream of filtered fluid passing through the fluid outlet port into the fluid reservoir provided in the interior region of the fluid reservoir housing, and
- an anti-drain valve arranged to move to an opened position opening the fluid outlet port to allow flow of filtered fluid from the filter chamber through the fluid outlet port to the fluid reservoir in response to installation of the filter module through the filter module-receiving aperture into the filter chamber and arranged to move to a normally closed position closing the fluid outlet port to block reverse flow of filtered fluid from the fluid reservoir through the fluid outlet port to the filter chamber in response to removal of the filter module from the filter chamber through the filter module-receiving aperture.

A fluid filtration system comprising
- a fluid reservoir housing formed to include an interior region and a filler port configured to conduct fluid into the interior region, the fluid reservoir housing including a top wall, a floor in opposing spaced-apart relation to the top wall, a first side wall coupled to the top wall and the floor, and a second side wall coupled to the top wall and the floor,
- a filter receiver arranged to extend into the interior region of the fluid reservoir housing, the filter receiver including an end wall coupled to the first side wall of the fluid reservoir housing and a longitudinal wall arranged to extend from the end wall to a receiver aperture formed in the second wall of the fluid reservoir housing, the end wall, longitudinal wall, and portions of the first and second side walls cooperating to define a filter chamber therebetween, the filter receiver also being formed to include a filter module-receiving aperture opening into the filter chamber, the first side wall being formed to include a fluid inlet port configured to admit unfiltered fluid into the filter chamber, the end wall being formed to include a fluid outlet port configured to discharged filtered fluid from the filter chamber into a fluid reservoir provided in the interior region of the fluid reservoir housing and outside of the filter receiver, and
- a filter module including a filter media and a connector coupled to the filter media and configured to mate with the filter receiver to expose the filter media to unfiltered fluid passing through the filter chamber from the fluid inlet port to the fluid outlet port and into the fluid reservoir provided in the fluid reservoir housing.
