Abstract
A fluid filter assembly includes a housing having a closed end and an open end; a filter element operably oriented in the housing; a baffle plate mounted to operably cover the housing open end; the baffle plate including a first axial face and an outer circumferential wall circumbscribing the first axial face; the outer circumferential wall being groove-free; the first axial face defining at least a first sealing groove; and a sealing gasket oriented in the first sealing groove; the sealing gasket forming a seal between the housing and the baffle plate. Methods of constructing, installing, and servicing includes fluids filters of the type described.
Claims9
A fluid filter comprising:
- (a) a housing having a closed end and an open end;
- (b) a filter element operably oriented in said housing;
- (c) a baffle plate mounted to operably cover said housing open end;
- said baffle plate including a first axial face and an outer circumferential wall circumscribing said first axial face;
- (i) said outer circumferential wall being groove-free;
- (ii) said first axial face defining at least a first sealing groove;
- and
- (d) a sealing gasket oriented in said first sealing groove;
- (i) said sealing gasket forming a seal between said housing and said baffle plate.
A method for constructing a fluid filter;
- the method comprising:
- (a) providing a housing having a closed end and an open end;
- (b) mounting a filter element and a baffle plate assembly into the housing through the open end;
- (i) the baffle plate including a sealing gasket mounted in an end face of the baffle plate;
- and
- (c) bending a portion of the housing against the sealing gasket to form a seal between the housing and the baffle plate.
A method of installing a filter assembly comprising:
- (a) spinning a filter assembly onto a filter head;
- the filter head being mounted on and in fluid communication with a fluid system of equipment;
- the filter assembly including:
- (i) a housing having a closed end and an open end;
- (ii) a filter element operably oriented in the housing;
- (iii) a baffle plate mounted to operably cover the housing open end;
- the baffle plate including a first axial face and an outer circumferential wall circumbscribing the first axial face;
- (A) the outer circumferential wall being groove-free;
- (B) the first axial face defining at least a first sealing groove;
- and
- (iv) a sealing gasket oriented in the first sealing groove;
- (A) the sealing gasket forming a seal between the housing and the baffle plate.
