Cartridge for dynamic reduction of a pressure of a fluid and related device for treating a fluid

A Device (100) for treating a fluid comprising:

• a cartridge (1) for dynamic reduction of a pressure of said fluid;
• a valve body (2) in fluid communication with the cartridge (1);
• wherein said cartridge (1) comprises:
• a main body (10) provided with:
• a first interface (11), configured for receiving said fluid at a first inlet pressure (P1);
• a second interface (12), configured for sending to said valve body (2) said fluid at a second intermediate pressure (P2);
• a third interface (13), configured for receiving said fluid at a third outlet pressure (P3) from said valve body (2);
• a passage (C1) adapted to place in fluid communication said first interface (11) and said second interface (12) and to allow the flow of said fluid from said first interface (11) to said second interface (12), said passage (C1) being extended in said main body (10) along a first direction (X1);
• and
• an internal chamber (C2) traversed by said passage (C1) and in fluid communication with said third interface (13), said internal chamber (C2) being extended in said main body (10) along a second direction (X2) that is not parallel to said first direction (X1);
• a shutter (14) movably housed in said internal chamber (C2) and separating said third interface (13) from said passage (C1), said shutter (14) being active on said passage (C1) in order to obstruct it at least partially in a selective and variable manner and to apply a reduction factor between said first pressure (P1) and second pressure (P2), said shutter being movable along said second direction (X2) at least between:
• a minimum interference position (Imin) with the passage (C1), wherein the obstruction of said passage is minimal and the reduction factor takes on minimum value;
• a maximum interference position (Imax), wherein the obstruction of said passage is maximum and said reduction factor takes on maximum value;
• at least one intermediate position (Imed) between said minimum interference position (Imin) and said maximum interference position (Imax) wherein said reduction value takes on an intermediate value between said minimum value and maximum value;
• and
• wherein the position of said shutter (14) is determined by said first inlet pressure (P1) and said third outlet pressure (P3);
• wherein said valve body (2) is in fluid communication with the second interface (12) of the cartridge (1) in order to receive said fluid at the second pressure (P2), said valve body (2) being configured at least for bringing said fluid at the third pressure (P3), said valve body (2) comprising:
• an inlet opening (21) in fluid communication with said second interface (12) to receive said fluid at the second pressure (P2);
• an outlet opening (22) for the outflow of fluid at said third pressure (P3) from said valve body (2);
• and
• wherein said device (100) is configured for placing said outlet opening (22) in fluid communication with said third interface (13) in order to send the fluid at the third pressure (P3) to said cartridge (1).
