Patent number: 9079129Abstract: A filter cartridge includes a substantially cylindrical filter media having a first end and a second end wherein the second end has an opening adaptable to receive a fluid outlet. The filter media is adapted to allow fluid to pass from an exterior of the filter media to an interior space of the filter media. A divider is positioned adjacent to the exterior of the filter media, and the divider has a closed end connected to the first end of the filter media and an open end that is longitudinally-spaced from the second end of the filter media such that at least a portion of the filter media located adjacent to the second end of the filter media is not directly adjacent to the divider. The divider extends a majority of the distance from the first end to the second end of the filter media.Type: GrantFiled: October 4, 2010Date of Patent: July 14, 2015Assignee: Davco Technology, LLCInventors: Paul B. Smith, Kevin J. Rucinski, Alfred Tondreau, Ken Conti

Patent number: 8051989Abstract: A support structure of a filter element for supporting a filter material that is adapted to filter a fluid includes a first frame portion and a second frame portion. The first frame portion has a plurality of radially-extending fingers that are longitudinally spaced from one another. The first frame portion is disposed entirely on an unfiltered side of the filter material. A second frame portion has a pair of longitudinally-extending support surfaces that are disposed in a spaced, facing relationship with respect to one another. The second frame portion is disposed entirely on a filtered side of the filter material. The radially-extending fingers of the first frame portion and each of the longitudinally-extending support surfaces of the second frame portion support the filter material to define a first radial channel. The radially-extending fingers of the first frame portion space the longitudinally-extending support surfaces of the second frame portion apart from one another.Type: GrantFiled: May 11, 2009Date of Patent: November 8, 2011Assignee: Davco Technology, LLCInventor: Alfred Tondreau

Patent number: 7854837Abstract: A filter cartridge includes a substantially cylindrical filter media and a pressure relieving structure. The filter media is adapted to allow fluid to pass from an exterior of the filter media to an interior space of the filter media. The pressure relieving structure is disposed at an upper end of the filter media, and the pressure relieving structure opens when a predetermined pressure level is established across the filter media to maintain the predetermined pressure across the filter media.Type: GrantFiled: November 10, 2008Date of Patent: December 21, 2010Assignee: Davco Technology, LLCInventors: Paul B. Smith, Kevin J. Rucinski, Alfred Tondreau, Ken Conti

Patent number: 7615146Abstract: A fluid filter assembly having a relief valve for visually indicating when a filter element may be replaced. The fluid filter assembly of the present invention provides a vertical, transparent housing having a fluid inlet for communicating a fluid into the housing and a fluid outlet for communicating fluid downstream of the housing. A filter element is disposed within the housing between the fluid inlet and the fluid outlet for filtering the fluid. The relief valve can also be in the form of a more restrictive filter media 42.Type: GrantFiled: October 17, 2006Date of Patent: November 10, 2009Assignee: Davco Technology, LLCInventors: Paul B. Smith, Kevin J. Rucinski, Alfred Tondreau, Ken Conti

Publication number: 20090139915Abstract: A fluid filter includes a vertical housing, a filter cartridge, and a bypass valve. The housing has a fluid inlet for communicating a fluid into the housing and a fluid outlet for communicating fluid downstream of the housing. The filter cartridge is disposed within the housing between the fluid inlet and the fluid outlet and includes a filter element for filtering the fluid, as well as means for maintaining and relieving a predetermined level of pressure across the filter element to provide an accurate visual indicator as to whether the filter element needs replacement. The bypass valve allows fluid to flow from an unfiltered side of the filter element to a filtered side of the filter element when the pressure across the filter element exceeds the predetermined pressure.Type: ApplicationFiled: February 11, 2009Publication date: June 4, 2009Applicant: DAVCO TECHNOLOGY, LLCInventors: Alfred Tondreau, Paul B. Smith, Kevin Rucinski, Kenneth A. Conti

Patent number: 7393455Abstract: A method and apparatus for filtering pressurized fluids, wherein a fluid level provides a visual indicator as to the general condition of the filter element. The present invention provides a vertical housing having a fluid inlet for communicating the fluid into said housing and a fluid outlet for communicating the fluid downstream of the housing. A filter element is disposed within the housing between the fluid inlet and the fluid outlet for filtering the fluid. The volume of air within the vertical housing is specifically determined in order to maintain a level of fluid which will indicate the general condition of the filter element.Type: GrantFiled: March 31, 2004Date of Patent: July 1, 2008Assignee: Davco Technology, L.L.C.Inventors: Alfred Tondreau, Kevin J. Rucinski
