Abstract
Abstract A strainer of filter assemblage for cleaning fluids in which a body is provided with a fluid inlet, a fluid outlet, an inlet header and an outlet header. A paper roll is supported by the body between the inlet header and the outlet header and through which the fluid to be cleaned must flow axially from the inlet header towards the outlet header. An elastic deformable sheath adapted to surround and constrict the paper roll is provided within the inlet header and located a distance from the wall thereof is adapted to be forced by the pressure of the fluid within the inlet header against the outer surface of the paper roll.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
101 words
A strainer assemblage for cleaning fluids including a body having a fluid inlet, a fluid outlet, an inlet header, an outlet header, a paper roll supported by the body between the inlet header and outlet header and through which the fluid to be cleaned must flow axially from the inlet header towards the outlet header, and an elastic deformable sheath surrounding and constricting the paper roll provided within the inlet header and located a distance from the walls thereof adapted to be forced by the pressure of the fluid within the inlet header against the outer surface of the paper roll.
Claim 2
Dependent Claim
101 words
A strainer assemblage for cleaning fluids including a body having a fluid inlet, a fluid outlet, an inlet header, an outlet header, a paper roll supported by the body between the inlet header and outlet header and through which the fluid to be cleaned must flow axially from the inlet header towards the outlet header, and an elastic deformable sheath surrounding and constricting the paper roll provided within the inlet header and located a distance from the walls thereof adapted to be forced by the pressure of the fluid within the inlet header against the outer surface of the paper roll.
Claim 3
Dependent Claim
44 words
The strainer assemblage as claimed in claim 1 in which said sheath is provided with an upturned portion at one end thereof adapted to bear against the wall of the inlet header and effect a seal between the inlet header and the outlet header.
Claim 4
Dependent Claim
26 words
The strainer assemblage as claimed in claim 2 in which sheath is of less diameter at its end opposite the end provided with said upturned portion.
Claim 5
Dependent Claim
27 words
The strainer assemblage as claimed in claim 2 in which said sheath is of greater diameter at its end opposite The end provided with said upturned portion.
Claim 6
Dependent Claim
25 words
The strainer assemblage as claimed in claim 2 in which said sheath at its end opposite said upturned portion is of stronger more rigid material.
Claim 7
Dependent Claim
23 words
The strainer assemblage as claimed in claim 1 in which said elastic deformable sheath is defined by a tube of an elastomeric material.
Claim 8
Dependent Claim
51 words
The strainer assemblage as claimed in claim 1 in which said elastic deformable sheath is defined by a hollow rounded body of an elastic stiff material overlapped approximately along at least one generating line of said body whereby the overlapped ends thereof are movable against and with respect to one another.
Claim 9
Dependent Claim
31 words
The strainer assemblage as claimed in claim 1 in which said sheath is defined by a deformable elastomeric tube doubled up with a contractable hollow body of an elastic stiff material.
Claim 10
Dependent Claim
64 words
The strainer assemblage as claimed in claim 1 in which at least a portion of said fluid inlet is provided with ports and an elastic deformable membrane surrounds the fluid inlet in the zone of said ports, with said membrane being adapted to be deflected outwardly by the pressure of the fluid within the fluid inlet against the inner surface of the paper roll.
