Electrically actuated valve having two ways and three positions

摘要

An electrically actuated valve (1) including a first working way (2) and a second working way (4) and an poppet (6) configured for providing a seal on a valve seat (A10) set hydraulically between the first working way (2) and the second working way (4), the poppet (6) including a first operating position, a second operating position, and a third operating position, and being displaceable by means of an electrical-actuation device (8),
wherein:
- in the first operating position, an passage area (A 0 ) for a hydraulic fluid defined between said valve seat (A10) and said poppet (6) has a maximum value;
- in the second operating position, said passage area (A 1 ) is partialized and has a value lower than said maximum value (A 0 ); and
- in the third operating position, said poppet (6) is in contact with said valve seat (A10), and the passage area (A 2 ) has a substantially zero value, so that the first working way (2) is isolated from the second working way (4).
