Abstract
Abstract An adapter for converting a filter system, having a source of fluid to be filtered and a discharge for filtered fluid, from use with a canister-type filter element to use with a disposable-type filter element, the adapter having a first coupling adapted for connection to the source; a base mounted on the coupling; a second coupling mounted on the base remote from the first coupling and adapted to receive a disposable-type filter element thereon, said element having a discharge opening for sealed attachment to the second coupling and a separate and distinct entrance opening; an input conduit operably interconnecting the first coupling and the entrance opening; and an output conduit operably interconnecting the second coupling and the discharge of the filter system.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
86 words
An adapter for converting a filter system, having a pressurized source of fluid to be filtered, comprising first coupling means secured to the source in fluid receiving relation; a base mounted on the first coupling means; a second coupling provided on the base and adapted to receive a filter element; and fluid transfer means operably interconnecting the first coupling means and the second coupling so as to transfer fluid under pressure from the source for filtering to and from an element mounted on the second coupling.
Claim 2
Dependent Claim
86 words
An adapter for converting a filter system, having a pressurized source of fluid to be filtered, comprising first coupling means secured to the source in fluid receiving relation; a base mounted on the first coupling means; a second coupling provided on the base and adapted to receive a filter element; and fluid transfer means operably interconnecting the first coupling means and the second coupling so as to transfer fluid under pressure from the source for filtering to and from an element mounted on the second coupling.
Claim 3
Dependent Claim
70 words
The adapter of claim 1 in which the transfer means has an input passage extending through the base for the transfer of fluid to the element and a distinct outPut passage extending through the base for the transfer of fluid from the element so as to establish a single directional flow of fluid to and from the element in an opposite direction to that normally utilized in the filter system.

Claim 10
Dependent Claim
67 words
The adapter of claim 2 in which the first coupling means includes an input coupling mounted on the base in operable connection to the source for transfer of fluid to be filtered from the source to the input passage and an output coupling mounted on the base in operable connection to the source for transferring filtered fluid from the output passage to the source for subsequent reuse.
Claim 11
Dependent Claim
49 words
an annular face circumscribing the inlet and outlet substantially concentrically of the outlet in juxtaposition with the annular mounting surface of the base; and d. a gasket disposed between the juxtaposed face and mounting surface for fluid tight compression therebetween when the filter element is tightened on the coupling.
Claim 12
Dependent Claim
