Publication number: 20120292240Abstract: A cartridge type filter is mounted in a housing and is serviced through the top of the housing. The cartridge includes first and second media packs axially stacked. The second media pack is in series behind the first media pack, and filters a portion of the liquid therethrough. The second media pack has a higher efficiency than the first media pack. The overall design has a drain system which allows liquid to drain from the interior of the filter housing and back to the sump before the filter cartridge is completely removed from the housing. Other optional features include an oil cooler, various valving, and a filter cartridge lockout mechanism.Type: ApplicationFiled: July 30, 2012Publication date: November 22, 2012Applicant: Donaldson Company, Inc.Inventors: John R.

Patent number: 8293103Abstract: 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.Type: GrantFiled: December 6, 2006Date of Patent: October 23, 2012Assignee: Donaldson Company, Inc.Inventors: Philip E.
