The invention relates to an improved three-way valve structure consisting of a main three-way valve body (1) with inlet (2) and outlet channels (3, 4) that communicate internally by means of an inner obturator element (5) actuated by a key (27), characterized by the relative position of the outlet channels which are perpendicularly arranged in relation to each other and in the same plane perpendicular to the inlet channel, the exterior form of the obturator (5) being a surrounding cylindrical shape and provided with, in the upper part thereof, flanges (9) for the seating of the same and sealing joints (12, 13), ending in a projecting rod (15) with a key seat shape that can fit into the key (27) of the valve. The key enables four functional positions by means of a quarter-circle turn: both outlets open, one outlet open and another closed and both outlets closed.

1. An improved three-way valve structure comprising a main valve body (1) equipped with an inlet channel (2) and two outlet channels (3, 4) having a quarter turn interior obturator element (5) housed in an interior of the main valve body (1) and manually actuated by a quarter turn of an exterior valve key (27), the cited inlet channel (2) being capable of communicating internally with the outlet channels (3, 4), wherein the outlet channels (3, 4) referred to are arranged perpendicular to each other, both outlet channels (3, 4) being in the same plane perpendicular to the cited inlet channel (2), while the obturator element (5) has a spherical shape; said structure being characterized in that the main valve body (1) ends in a flat face (21) in an upper part thereof, on a surface of which are four indentations (22) distributed crosswise at 90° to each other, on which a positioning washer (23) of the valve key (27) is supported, said positioning washer (23) having a flat shape and four valve operating positions, said positions being established by the connection made between the inlet channel (2) and the outlet channels (3, 4), further comprising at least two diametrically opposing projections (24) and being capable of fitting in the indentations (22) with a flexible joining (25), a shape of a central hole (26) of the positioning washer (23) matching an exterior key seat shape of a rod (15) of the obturator element (5); wherein the valve key (27) adopts, in an interior part thereof, a shape of a cavity (28) which matches, in a housing thereof, the key seat shape of the rod (15) of the obturator element (5); wherein the rod (15) and the cavity (28) constitute a cotter which unifies the movement of both valve key (27) and obturator element (5) joined by way of the positioning washer (23), said positioning washer (23) being fitted around the outer surface of the cavity (28) inside the valve key (27); and wherein the positioning washer (23) and the at least two diametrically opposing projections (24) form a single piece. 2. The improved three-way valve structure according to claim 1, characterized in that an interior structure of the obturator element (5) comprises a longitudinal channel from a lower inlet (6) at a base thereof to an upper bifurcation with two transversal outlet openings (7, 8) both arranged perpendicularly at 90° and in a plane perpendicular to the inlet channel, while the obturator element (5), at an exterior part thereof, is provided, in an upper part thereof, with a protruding flange (9) capable of fitting into an interior recess (14) with similar dimensions in the interior of the main valve body (1) and with two housings (10, 11) of sealing joints (12, 13), the obturator element (5) ending, at the upper end thereof in the protruding rod (15) with the key seat shape that can fit in the valve key (27). 3. The improved three-way valve structure according to claim 1, characterized in that the structure defined in this way enables four functional positions of the valve, established by the connection implemented between the inlet channel (2) and the outlet channels (3, 4), one of the positions being with both outlets open, two positions with only one outlet open and another closed and a final position with both outlets closed by a quarter-circle turn of the valve key (27). 4. The improved three-way valve structure according to claim 1, characterized in that the aforementioned structure has two sealing joints (16, 17) inserted in an interior of each one of the outlet channels (3, 4), inserted pressed against an exterior surface (18) of the obturator element (5), pushed by retaining clips (19, 20) immovable in a radial slot formed in the interior of each one of the outlet channels (3, 4). 5. The improved three-way valve structure according to claim 1, characterized in that the valve key or control (27) is provided in turn with at least two projections (29, 30) and (30) distributed at 90° over the exterior surface thereof for visual and exterior identification of the functional open or closed position of the valve in different positions thereof. 6. The improved three-way valve structure according to claim 1, characterized in that the exterior key seat shape of the rod (15) of the obturator element (5), which matches the shape of the central hole (26) of the positioning washer (23), is not cylindrical. 7. The improved three-way valve structure according to claim 1, characterized in that the central hole (26) of the positioning washer (23) is fitted to rod (15) of the obturator element (5) thereby requiring the positioning washer (23) to rotate when the rod (15) rotates.
