Abstract
Abstract A valve for controlling fluid flow and particularly useful as a bypass valve for water treatment equipment. The valve is characterized by a casing provided with parallel main and auxiliary bores intersected by a plurality of passages and reciprocably accommodating a valve member for movement in the main bore between bypass and water treatment positions. The axes of the bores and passages lie in the same plane to facilitate water flow and simplify installation, and the auxiliary and main bores are preferably cylindrical and of approximately the same diameter so that the valve is thereby capable of flexibility in mounting auxiliary elements such as strainers, shutoff valve members and the like.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
272 words
A bypass valve for water treatment equipment, said valve comprising: a casing including an auxiliary bore intersected by longitudinally spaced inlet and outlet passages, a main bore parallel to said auxiliary bore and intersected by longitudinally spaced feed and discharge passages, said casing further including a pair of transfer passages coupling said auxiliary and main bores, and a transverse wall between said pair of transfer passages dividing said auxiliary bore into a pair of sections; and a valve member mounted for reciprocation in said main bore and having a bypass position in which said feed and discharge passages are isolated from said transfer passages whereby water is constrained to flow from said inlet passage through one of said sections, through the adjacent one of said transfer passages and into said main bore, through the other of said transfer passages, through the other of said sections, and through said outlet passage, said valve member having a water treatment position in which said feed and discharge passages are connected to said transfer passages whereby water is constrained to flow from said inlet passage through said one of said sections, through the adjacent one of said transfer passages and into said main bore, through said feed passage and back through said discharge passage after passing through said water treatment equipment, back into said main bore, through the other of said transfer passages, through the other of said sections, and through said outlet passage, the longitudinal axes of said main and auxiliary bores and all of said passages lying in the same plane whereby said valve is adapted to compactly fit against a flat mounting surface.
Claim 2
Dependent Claim
272 words
A bypass valve for water treatment equipment, said valve comprising: a casing including an auxiliary bore intersected by longitudinally spaced inlet and outlet passages, a main bore parallel to said auxiliary bore and intersected by longitudinally spaced feed and discharge passages, said casing further including a pair of transfer passages coupling said auxiliary and main bores, and a transverse wall between said pair of transfer passages dividing said auxiliary bore into a pair of sections; and a valve member mounted for reciprocation in said main bore and having a bypass position in which said feed and discharge passages are isolated from said transfer passages whereby water is constrained to flow from said inlet passage through one of said sections, through the adjacent one of said transfer passages and into said main bore, through the other of said transfer passages, through the other of said sections, and through said outlet passage, said valve member having a water treatment position in which said feed and discharge passages are connected to said transfer passages whereby water is constrained to flow from said inlet passage through said one of said sections, through the adjacent one of said transfer passages and into said main bore, through said feed passage and back through said discharge passage after passing through said water treatment equipment, back into said main bore, through the other of said transfer passages, through the other of said sections, and through said outlet passage, the longitudinal axes of said main and auxiliary bores and all of said passages lying in the same plane whereby said valve is adapted to compactly fit against a flat mounting surface.
Claim 3
Dependent Claim
21 words
A bypass valve according to claim 1 wherein said main and auxiliary bores are cylindrical and of approximately the same diameter.
Claim 4
Dependent Claim
34 words
