摘要
The valve (300) is formed in a valve body (301) housing a first path portion (306), a second path portion (307), and an coupling zone (309) between the first and second path portions. A shutter (302; 315; 318; 319) is arranged in the coupling zone and has a shutting portion (302; 317) of ferromagnetic material that is deformable under the action of an external magnetic field between an undeformed position, wherein the shutter closes the coupling zone, and a deformed position, wherein the shutter at least partially frees the coupling zone. The shutting portion (302; 317) of the shutter (302; 315; 318; 319) is formed by a rubber membrane incorporating particles, for example of ferrite particles.
