Abstract:
An in-line liquid filtration device comprising:a housing having an inlet port and an outlet port therein;at least one filter element disposed within the housing between the inlet port and outlet port and dividing the housing into a first chamber and a second chamber, said filter element being disposed within said housing to prevent liquid from flowing in between the filter element and the housing;a channel within said second chamber having a cross sectional flow area defined by the inner surface of said channel and said filter element, said channel being in direct fluid flow relationship with said outlet port and having a cross sectional flow area which, along a length of the channel having a portion adjoining the outlet port and upstream of the port, is less than or equal to the cross sectional flow area of the outlet port wherein air within said channel is forced by filtered liquid therein to flow through a portion of said channel leading to said outlet port thereby removing air contacting said filter element from the downstream side of the device.
