FILTER FOR FLUID SUPPLY SYSTEM

摘要

A filter includes housing and a filter device disposed within the housing to define a circumferential cavity therebetween. The filter further includes a cap coupled to an inlet port and the cap includes a first thread portion. The filter further includes a first seal member attached to a first end of the filter device to restrict entry of fluid from the circumferential cavity into a hollow center tube disposed within the filter device. The filter further includes an engagement member provided on the first seal member and the engagement portion includes a second thread portion. The first thread portion of cap is adapted to engage with the second thread portion of the engagement member for removing filter device from the housing. Further, a second seal member is attached to a second end of the filter device to restrict flow of the fluid from the circumferential cavity into a drain port.

1. A filter for a fluid supply system, the filter comprising:
a housing having an inner surface and an outer surface, the housing including:
an inlet port adapted to receive fluid into the housing; anda drain port adapted to drain the fluid from the housing; a cap detachably coupled to the inlet port, the cap including a first thread portion; a filter device having an inner surface and an outer surface, the filter device disposed within the housing to define a circumferential cavity between the outer surface of the filter device and the inner surface of the housing, the circumferential cavity being in fluid communication with the inlet port of the housing to receive the fluid into the circumferential cavity from the fluid supply system; a hollow center tube disposed within the filter device, the hollow center tube includes a first end and a second end, the first end being fastened to a base portion of the housing and adapted to supply the fluid to one or more downstream components of the fluid supply system; a first seal member attached to a first end of the filter device, the first seal member adapted to restrict entry of the fluid from the circumferential cavity into the hollow center tube via the first end of the filter device; an engagement member provided on the first seal member, the engagement member extending in a direction perpendicular to a surface of the first seal member and away from the first end of the filter device, wherein the engagement member includes a second thread portion; and a second seal member attached to a second end of the filter device, the second seal member includes:
a first annular ring extending in a direction perpendicular to a surface of the second seal member and disposed distal from the hollow center tube, wherein the first annular ring restrict flow of the fluid from the circumferential cavity into the drain port in an engaged position portion of the filter device; anda second annular ring extending in a direction perpendicular to the surface of the second seal member and proximal to the hollow center tube, wherein the second annular ring restrict flow of the fluid from the hollow center tube into the drain port in the engaged position of the filter device, wherein the first thread portion of the cap engages with the second thread portion of the engagement member for removing the filter device from the housing.
