This application relates to a fluid filter of the spin-on type.
Spin-on filter assemblies include two parts—a filter head with a threaded spud and a removable and replaceable filter cartridge. The filter head is typically permanently mounted to equipment, such as an engine, hydraulics, or a generator. The filter head has inlet channels for conveying fluid to be filtered to the filter cartridge, and outlet channels for conveying fluid that has been filtered by the cartridge for use by the equipment. The filter cartridge will typically include an outer can or housing holding a filter element of filter media therewithin. The filter cartridge is typically useable over some limited duration due to the limited life of the filter media within. The filter cartridge is removed from the filter head and disposed of and is then replaced with a new filter cartridge. The filter cartridge and filter head are removably connected to each other, typically through a threaded connection. The spud on the filter head will typically have threads, while the filter cartridge will have a threaded aperture to fit on the threaded spud. The threaded connection between the filter cartridge and filter head can sometimes present a leak path for unfiltered fluids. That is, sometimes fluid that has not been filtered can travel along the threads and reach the clean side of the filter without first passing through the filter media. This leakage can lead to particulate material traveling to downstream equipment, which can present problems. Improvements are desirable.
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. The baffle plate defines a central flow aperture. The baffle plate defines a continuous groove immediately adjacent to and circumscribing the central flow aperture. The seal arrangement is secured to the baffle plate spaced from and circumscribing the continuous groove.
In another aspect, a filter assembly includes a spin-on filter cartridge as characterized above and a filter head. The spin-on filter cartridge is removably mountable on the filter head. The filter head includes a central spud defining outer threads. An O-ring seal member is operably oriented around the central spud. When the spin-on filter cartridge is operably oriented on the filter head, the O-ring 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.
In another aspect, a method of assembling a filter assembly includes spinning a filter cartridge as characterized above onto a filter head to form a primary seal between the baffle plate on the filter cartridge and the filter head, and until a seal member fixed to the filter head is received within the continuous groove.
In another aspect, a filter head is provided. The filter head includes a block defining fluid flow channels; a central spud having a threaded outer wall; and a seal member secured to and circumscribing the central spud.
In
A baffle plate is shown at 30. The baffle plate 30 is operably oriented over the housing open end 16. The baffle plate 30 defines a central flow aperture 32. In preferred embodiments, the central flow aperture 32 is an outlet aperture forming an outlet arrangement.
While a variety of implementations of baffle plates 30 are usable without departing from design principles of this disclosure, one type of baffle plate is illustrated in
The baffle plate 30 further includes a groove 50, and in the embodiment shown, a continuous groove 50. In preferred implementations, the continuous groove 50 is a circular groove 50. The groove 50 is defined by a radial surface 52 and an axial support surface 54 generally orthogonal to the radial surface 52. In some embodiments, the radial surface 52 is a sealing surface; in some embodiments, the support surface 54 functions as a sealing surface. Immediately adjacent and intersecting the support surface 54 is hub interior 36 including the threaded section 38. The groove 50 is immediately adjacent to and circumscribes the central flow aperture 32. The groove 50 operates as a seat 56 for a seal member, such as an O-ring. In the embodiment shown, the central hub 34 terminates at the central groove 50 along an axial face 51 of the baffle plate 30.
The baffle plate 30 further includes a seal arrangement 70 secured to the baffle plate 30 spaced from and circumscribing the continuous groove 50. The seal arrangement 70 is seated within a groove 72. The seal arrangement 70 can be an O-ring seal member 73. The seal member 73 forms a primary seal 76 (
In reference now to
The filter head 40 generally comprises a block 85 defining fluid flow channels 68, including inlet channel 67 (
In operation, when the filter cartridge 10 is spun on and operably oriented on the filter head 40, the O-ring seal member 62 is received within the continuous groove 50 and forms a seal 80 (
Once the filter cartridge 10 is operably oriented on the filter head 40, in a forward flow system, fluid to be cleaned enters the filter head 40, 40′ through, for example, one of the fluid flow channels 68 (
