FLUID CIRCULATING AND INTERCEPTING DEVICES

摘要

A fluid circulating and intercepting device (10) comprises a first (12) and a second block (11) facing each other with the interposition of an impermeable elastic and flexible diaphragm (13). The first block (12) is provided with at least one concavity (16) with its mouth close. to the diaphragm (13) and into which opens out in a substantially axial direction a control fluid feed duct (15). The second block (11) is provided with ducts (14, 15) for circulation of the intercepted fluid which open out on the face in contact with the diaphragm (13), in correspondence with the concavity (16) in the first block (12).
