Abstract
A fluid filter has a housing fabricated from two portions made from a toxic resistant plastic, such as TEFLON, and includes a filter element sealingly supported therein in such a manner that contaminants or foreign material filtered thereby is captured in an area closed off by novel seals formed between the two housing portions. The seals may take the form of an accordion-type seal, or, male-female type engaging ends may be used. The seals allow the filter element to be removed and examined, if needed, and allows the housing portions to be easily and quickly assembled and disassembled for repair or examination.
Claims12
A fluid filter device for installation in a pressurized line containing caustic or corrosive fluid comprising, in combination:
- a body having a first male portion and a second female portion;
- a hollow chamber formed in said body between said first male portion and said second female portion;
- fluid passages formed through said first male portion and said second female portion and connected to said hollow chamber;
- filter means secured between a pair of filter holding disks in said hollow chamber;
- a plurality of concentric walls having spaces therebetween formed on said pair of filter holding disks and fluidly connected to said filter means;
- sealing means formed between said first male portion and said second female portion to prevent leakage of fluid from said filter device;
- and
- said first male portion including an annular wall having a tapered end and a plurality of internal and external cuts formed on said annular wall to allow said annular wall to collapse when compressed in an accordion-type manner, to provide an effective internal seal between said first male portion and said second female portion.

- a body having a first male portion and a second female portion;
- a hollow chamber formed in said body between said first male portion and said second female portion;
- fluid passages formed through said first male portion and said second female portion and connected to said hollow chamber;
- filter means secured between a pair of filter holding disks in said hollow chamber;
- a plurality of concentric walls having spaces therebetween formed on flat surfaces and fluidly connected to said filter means;
- and
- the elements of said filter being sized and dimensioned to enable said first male portion to be sealingly secured in said second female portion by a compressive accordian sealing means.

- a plurality of spaces formed in said pair of filter holding disks between said plurality of concentric walls;
- a plurality of openings formed in said pair of filter holding disks and fluidly connected to said spaces;
- a filter means held between flat surfaces of said pair of filter holding disks;
- means for clamping said first male portion and said second female portion together;
- sealing means formed between said first male portion and said second female portion to prevent leakage of fluid from said filter device;
- and
- said first male portion including an annular wall having a tapered end and a plurality of internal and external cuts formed on said annular wall to allow said annular wall to collapse when compressed, to provide an effective internal seal between said first male portion and said second female portion.
