Filter cartridge assembly and method of manufacture thereof

摘要

A filter cartridge has a longitudinal axis. A cartridge housing has first and second shell portions. The first shell portion has a cartridge housing opening and an annular element retention lip which is disposed axially inward of the opening and coaxial with the longitudinal axis. The filter element has a first end cap, a second end cap, and a continuous ring of filter media disposed between the first and second end caps. The first end cap defines a fuel flow port which is coaxial with the longitudinal axis. A plurality of resilient element retention arms extend axially from the first end cap, and surround the fuel flow port. The arms terminate in retention barbs which are mateable with the annular lip. The resilient retention arms hold the retention barbs against the annular lip, suspending the filter element within the cartridge.

主权项

1. A filter element having a longitudinal axis comprising:
a first end cap having a main body, said main body defining a fuel flow port coaxial with said longitudinal axis, and a plurality of resilient filter element retention arms extending axially from said main body and surrounding said fuel flow port, said retention arms terminating in retention barbs, a second end cap, and a continuous ring of filter media having one end attached to said first end cap and an opposing end attached to said second end cap, wherein support ribs extend radially outwardly from said resilient filter element retention arms to a perimeter of said first end cap, to define a plurality of fuel-flow pathways directing fuel radially outwardly from said fuel flow port.
