摘要： A diaphragm (1) for adjusting the useful passage area in submersed devices for oxygenating tanks for collecting storm sewage and wastewater, said devices comprising a water feed pipe (4) which is coupled to the delivery (5) of a pumping element and a branch pipe (6) for feeding air which is inserted downstream of a narrower Venturi tube section, comprising a contoured plate (7) which is crossed by a port (8) with a calibrated diameter which is smaller than the diameter of the feed pipe (4) and can be hermetically inserted in a drawer-like fashion in a corresponding slot (4a) formed transversely in the water feed pipe (4) directly upstream of the insertion point of the branch pipe (6).

摘要： It is described a roller (1) of a flexographic printing machine, such as an inking roller, which comprises a cylindrical support (2), a sleeve (3) arranged in an exchangeable way on the cylindrical support (2) and locking means (4) adapted to lock the sleeve (3) on the cylindrical support (2). The sleeve (3) has a stiff structure in a radial direction and achieves with the cylindrical support (2) a matching form. The locking means (4) comprises at least one locking pin (5) arranged within a respective housing (6) obtained in the cylindrical support (2) in a radial position, and actuating means (7) of the locking pin (5) that is adapted to cause pass selectively the locking pin (5) between a first configuration, wherein the locking pin (5) protrudes to contrast with the sleeve (3) put on the cylindrical support (2) to block it, and a second configuration, wherein said locking pin (5) is completely contained into said housing (6) and said sleeve (3) can be engaged/disengaged on/from said cylindrical support (2).
