Abstract

A multiflow delivery unit has a first conduit (2) with a first inlet end (4) for connection to the water mains (W) and a first outlet end (5) for delivery of a water flow, a second conduit (3) with a second inlet end (6) for connection to an airflow supply line (A) and a second outlet end (7) for delivery of the airflow. One of the two conduits (2, 4) is at least partially contained in the other whereby the first outlet end (5) and the second outlet end (7) are substantially coplanar. A substantially tubular diffuser (8) is provided between the conduits (2, 3) at their respective outlet ends (5, 7). The diffuser (8) has a first passage (9) connected to the first outlet end (5) and a plurality of second passages (10) separate from the first passage (9) and connected to the second outlet end (7). The upstream end face of the diffusor is flat whereas the downstream end face (13) has an inwardly converging countersunk annular surface (17) at the periphery of the first passage (9). The second passages have outlet sections (16) for delivering air in corresponding direction (Y) which are converging toward the longitudinal axis (L) of the diffuser.

Claims

1. A multiflow delivery unit, comprising:

a first water conduit (2) with a first inlet end (4) for connection to the water mains (W) and a first outlet end (5) for water flow delivery;

a second water conduit (3) with a second inlet end (6) for connection to airflow supply means (A) and a second outlet end (7) for airflow delivery;

wherein one of said conduits (2, 3) is entirely contained in the other, and wherein said first outlet end (5) and said second outlet end (7) are substantially coplanar, a diffuser (8) being further provided, which has a substantially tubular shape and a longitudinal axis (L) interposed between said conduits (2, 3) at said outlet ends (5;

7), said diffuser (8) having a first passage (9) connected to said first outlet end (5) and at least one second passage (10) separate from the first passage (9) and connected to said second outlet end (7) for delivery of respective flows;

characterized in that said diffuser (8) has an upstream end face (12) and a downstream end face (13), as oriented relative to respective water and air flows, said upstream end face (12) being substantially flat and said downstream end face (13) having an inwardly converging countersunk annular surface (17) at the periphery of said at least one first passage (9), said second passage having an outlet section (16) at said annular surface (17) for the outflow of air in a corresponding direction (Y) converging toward said longitudinal axis (L).

2. A delivery unit as claimed in claim 1, characterized in that said first conduit (2) is substantially coaxial with said second conduit (4).

3. A delivery unit as claimed in claim 1, characterized in that said diffuser (8) has a substantially annular shape, said at least one first passage (9) being provided at a substantially central position, and said at least one second passage (10) being provided at the periphery of said first passage (9), with a substantially curved cross section.

4. A delivery unit as claimed in claim 3, characterized in that said diffuser (8) comprises a plurality of second longitudinal passages (10) having identical cross sections and arranged in evenly and angularly offset positions.

5. A delivery unit as claimed in claim 1, characterized in that said outlet cross section (16) is smaller than the cross section of said second end (7) of said second conduit (3).

6. A delivery unit as claimed in claim 1, characterized in that it comprises a connecting sleeve (18) with a third conduit (19) and a fourth conduit (22), wherein said third conduit (19) has a first inlet port (20) connected to the water mains (W) and a first outlet port (21) connected to said first inlet end (4) and wherein said fourth conduit (22) has a second inlet port (23) connected to airflow supply means (A) and to a second outlet ort (24) connected to said second inlet end (6).

7. A delivery unit as claimed in claim 1, characterized in that it comprises flow control means (26) of manual and/or automatic types, which are adapted to control water flow in said first outlet end (5).

8. A delivery unit as claimed in claim 7, characterized in that said flow control means (26) are adapted to vary the ratio of the flows coming from respective hot water and cold water circuits (W_H, W_C) connected to the water mains (W), in the first outlet end (5).
