Spin-on filter assembly and methods

摘要

A spin-on filter cartridge includes a housing, a filter element operably oriented in the housing, a baffle plate, and a seal arrangement. The baffle plate is operably oriented over the housing open end and defines a central flow aperture. The baffle plate also defines a continuous groove immediately adjacent to and circumscribing the central flow aperture. The seal arrangement is secured to the baffle plate and spaced from and circumscribing the continuous groove. A filter assembly including the spin-on filter cartridge and a filter head is also disclosed wherein the filter cartridge is removably mountable on the filter head. When the spin-on filter cartridge is oriented on the filter head, a seal member is received within the continuous groove and the seal arrangement forms a seal between and against the baffle plate and the filter head. The seal can be radial or axial or have both axial and radial components.
