Abstract
Abstract A filter particularly for use with industrial waters includes a substantially cylindrical filter housing an inlet pipe inclined on its axis and an axial outlet pipe. A fixed strainer is arranged in the filter housing and communicates with the outlet pipe. Inside the strainer is a substantially conical deflector having a nose which is directed towards the outlet pipe. At least one fin, and, in practice, at least one longer fin and at least one shorter fin extends radially between the deflector and the strainer.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
95 words
An industrial water filter, comprising a substantially cylindrical filter housing, inlet means extending peripherally into said housing, outlet means located axially of said housing and at one end thereof, a fixed generally cylindrical strainer located within said housing and having an internal space communicating with said outlet means, a substantially conical deflector located inside said strainer and converging towards said outlet means, and at least one fin extending radially in the path of water passing through said strainer between said deflector and said strainer from said strainer to said deflector and axially of said outlet.
Claim 2
Dependent Claim
95 words
An industrial water filter, comprising a substantially cylindrical filter housing, inlet means extending peripherally into said housing, outlet means located axially of said housing and at one end thereof, a fixed generally cylindrical strainer located within said housing and having an internal space communicating with said outlet means, a substantially conical deflector located inside said strainer and converging towards said outlet means, and at least one fin extending radially in the path of water passing through said strainer between said deflector and said strainer from said strainer to said deflector and axially of said outlet.
Claim 3
Dependent Claim
41 words
A filter according to claim 1, comprising at least one longer fin which extends approximately over the entire axial length of the deflector, and at least one shorter fin which extends over a portion of the axial length of the deflector.
Claim 4
Dependent Claim
20 words
A filter according to claim 2, wherein a shorter fin extends over approximately half the axial length of the deflector.
Claim 5
Dependent Claim
17 words
A filter according to claim 2, comprising a plurality of shorter fins uniformly distributed about a circle.
Claim 6
Dependent Claim
28 words
A filter according to claim 1, wherein at least one fin extends at right-angles to the inlet means, and approximately over the entire axial length of the deflector.
Claim 7
Dependent Claim
15 words
A filter according to claim 1, wherein the fins are firmly fixed to the deflector.
Claim 8
Dependent Claim
17 words
A filter according to claim 1, wherein the deflector and the fins extend into the outlet means.
Claim 9
Dependent Claim
31 words
A filter according to claim 1, wherein the deflector comprises a divergent end in the form of a fixing flange and a convergent end in the form of a rounded nose.
Claim 10
Dependent Claim
25 words
A filter according to claim 8, wherein the divergent end and the convergent end of the deflector are each provided with at least one opening.
Claim 11
Dependent Claim
54 words
A filter according to claim 1, comprising a retaining wall at right-angles to that generatrix of the strainer which is circumferentially furthest from the inlet means, which wall forms a recovery box with the strainer, wherein a fin extends at right-angles to the generatrix, and approximately over the entire axial length of the deflector.
