Abstract
Abstract A hydraulic distribution and control unit has a chamber with an inlet (1a) and at least two subchambers. A partition wall (5) separates the subchambers one from another. One edge of the partition wall crosses the inlet to the main chamber, dividing the inlet into layers at different levels. The uppermost subchamber has an overfall edge (4a) and the lowermost subchamber includes an underflow (8).

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
114 words
A distribution and control unit comprising: a chamber including an inlet (1a) and at least two subchambers including a lowermost subchamber and an uppermost subchamber; at least one substantially impervious partition wall (5) disposed within the chamber for separating the subchambers one from another; the partition wall including a partition wall edge disposed at the inlet for dividing a flow of water from the inlet into at least two layers at different respective levels; a lowermost one of the levels communicating with the lowermost subchamber (7); an uppermost one of the levels communicating with the uppermost subchamber (6); the uppermost subchamber including an overfall edge (4a); and the lowermost subchamber including an underflow (8).
Claim 2
Dependent Claim
114 words
A distribution and control unit comprising: a chamber including an inlet (1a) and at least two subchambers including a lowermost subchamber and an uppermost subchamber; at least one substantially impervious partition wall (5) disposed within the chamber for separating the subchambers one from another; the partition wall including a partition wall edge disposed at the inlet for dividing a flow of water from the inlet into at least two layers at different respective levels; a lowermost one of the levels communicating with the lowermost subchamber (7); an uppermost one of the levels communicating with the uppermost subchamber (6); the uppermost subchamber including an overfall edge (4a); and the lowermost subchamber including an underflow (8).
Claim 3
Dependent Claim
63 words
The distribution and control unit according to claim 1, wherein, from one of the subchambers (7; 21) of the chamber (4) next to the uppermost subchamber, a connection is provided to an overflow (11; 18) with an overflow edge (19) at the same height or lower than the overfall edge (4a), said overflow being connected via the overflow edge to the underflow (8).
Claim 4
Dependent Claim
28 words
The distribution and control unit according to claim 2, wherein respective heights of at least one of the overall edge (4a) and the overflow edge (19) are adjustable.
Claim 5
Dependent Claim
38 words
The distribution and control unit according to claim 2, wherein the overflow (18) is connected with a reservoir (16) comprising an outlet lower than the overflow edge and connected through a non-return valve (17) with the chamber (4).
Claim 6
Dependent Claim
46 words
The distribution and control unit according to claim 2, wherein a tube (23) leads from said one of the subchambers (7; 21) of the chamber (4) next to the uppermost subchamber and said tube is connected with the overflow (18), which is placed outside the chamber.
Claim 7
Dependent Claim
63 words
The distribution and control unit according to claim 2, further comprising a second partition wall (20) dividing a lower layer of water from the inlet (1a) into a pair of layers and providing a corresponding division of the lower subchamber of the chamber into two separate sublevels; a lower sublevel comprising the underflow (8) and upper sublevel being connected with the overflow (18).
Claim 8
Dependent Claim
36 words
The distribution and control unit according to claim 1 comprising a delivery pipe (1), wherein the cross section of the delivery pipe at the inlet (1a) extends higher than the cross section of the inlet proper.
Claim 9
Dependent Claim
58 words
The distribution and control unit according to claim 1, including a siphon device (17) at the overfall edge (4a), said siphon device (17) including a siphon inlet inside the chamber and a discharge side outside the chamber, whereby the uppermost subchamber (5) of the chamber (4) is emptied at least partially after the overfall has been in function.
Claim 10
Dependent Claim
24 words
The distribution and control unit according to claim 8, wherein the discharge side of the siphon device (17) is connected to an outlet (22).
Claim 11
Dependent Claim
35 words
The distribution and control unit according to claim 9, wherein the siphon device is provided with siphon inlets at the upper part of the delivery pipe (1) at the inlet (1a) of the chamber (4).
Claim 12
Dependent Claim
69 words
The distribution and control unit according to claim 1, wherein at the inlet (1a) a containment boom (27) is provided, said boom extending transversely to the width of the inlet (1) and being adapted to follow a water level in the inlet (1a), and including hold means (33) for preventing a lower edge of the containment boom (27) from being lifted to an upper edge of the inlet (1a).
Claim 13
Dependent Claim
15 words
The distribution and control unit according to claim 1, wherein the inlet edge is curved.
