Abstract: A device for controlling flow of a flow agent in a pipe system, the device comprising: a pipe housing (1) comprising a pipe cavity (2) with one or multiple openings in a pipe cavity wall of the pipe cavity, the one or multiple openings defining an outlet port (3) of the device, and the pipe cavity having an open end defining an inlet port (6) of the device, and a closed end (7), wherein the closed end is closed by a dismountable end body (15); the pipe cavity comprising a first portion having a first cross sectional area and a second portion having a reduced cross sectional area (4), smaller than the first cross-sectional area, the second portion being located between the open end and the one or multiple openings in the pipe cavity wall.

Abstract: A low pressure water mist nozzle for active fire protection from water supplied with supply water pressures of 0.5 bar to 20 bars, characterized by having a separation wall (3) with multiple openings (4) of sizes 01 mm to 02, 5 mm in angles of 10° to 50° to the wall surfaces, which are followed by a cavity (8) having a centrally located outlet opening (6) in its end wall, which are located opposite the separation wall (3) containing multiple openings (4).

Abstract: The invention is characterized by consisting of a body (1) with a central cavity (2) having an open inlet-port (3), and one or multiple cylindrical shaped cavities (4i), which are connected to the central cavity via one or 5 more openings (5i) with cross section areas less that the cylindrical cavity (4i), and where there is one centrally located opening (6i) in the cylindrical cavity end surfaces opposite the openings (5i) into the central cavity (2).
