초록 ▼

Embodiments of a key system for filters and their connecting heads, brackets, or other holders are shown. The filter cartridge and its holder each have a keyed surface, one being a protruding “key” and one being a recessed “lock”. Cooperation of these keyed surfaces is required in order for the filter cartridge to be installed in the holder, so that mis-matched cartridges cannot be installed into the holder, for example, to prevent a particular type of cartridge from being placed in a filtration or other process where it would be inappropriate, or undesired. The keyed surfaces are selectively locate-able preferably at different circumferential locations on a perimeter of the filter and a corresponding location on a perimeter of the head/holder. The perimeter may be, for example, on an outer shoulder surface of a filter and an inner surface of a valve head, or on outer and inner surfaces of connectors that provide a liquid seal between the filter and the head/holder.

1. A filter for liquid for connection to a filter head having first and second keyed recess structures that are diametrically-opposed 180 degrees from each other, the filter comprising: a generally cylindrical housing containing media for filtration or treatment of liquid, the housing having a top end, a bottom end, a central axis between said top end and said bottom end, and an axial sidewall, an upper corner connecting the top end and the axial sidewall, and a neck upending from the top end at or near the central axis and containing fluid connections for connection to a filter head;wherein the housing further comprises a first protrusion structure having a top extremity and a bottom extremity, and comprising a first set of three key protrusions protruding radially outward from a circumferential surface between the central axis and said upper corner, wherein the three key protrusions are separated by spaces each extending entirely through the first protrusion structure from the top extremity to the bottom extremity, the first set of key protrusions all being within a range of 30-70 degrees on the circumferential surface;and the housing further comprising a second set of key protrusions protruding radially outward from the circumferential surface, diametrically-opposed 180 degrees from said first set, and the second set of key protrusions being within a range of 30-70 degrees on said circumferential surface;wherein each of said spaces separating the three protrusions has a circumferential space length, and each of the three protrusions of said first set has a circumferential length that is three or more times said space length, whereby all three protrusions of said first set fit in the first recess structure of the filter head to connection the filter to the filter head. 2. The filter as in claim 1, wherein said second protrusion structure has a top extremity and a bottom extremity, and the protrusions of said second set are separated by second-set spaces each having a circumferential space length and each extending through the second protrusion structure from the top extremity to the bottom extremity of said second protrusion structure, and each of the protrusions of said second set having a circumferential length that is three or more times said second-set space length, whereby all the protrusions of the second set fit in the second recess structure of the filter head to connect the filter to the filter head. 3. The filter as in claim 2, wherein said second set of key protrusions consists only of three protrusions separated by said second-set spaces. 4. The filter as in claim 1, wherein said first protrusion structure consists only of said three protrusions separated by said spaces.
