Publication number: 20120175541Abstract: A valve assembly including a valve body with inlet and outlet ports, between which there is a main valve seat cooperating with an associated main obturator. The obturator defines together with the valve body, a variable volume control chamber in permanent communication with the inlet port through a first passage having a reduced cross-section. The control chamber is adapted to be brought into communication with the outlet port through a second passage having a larger cross-section. Also provided is a solenoid pilot valve including a control coil and a movable core associated with an auxiliary obturator adapted to open and close the second passage. Between the second passage and the outlet port, is defined a second variable volume control chamber, which is delimited in part by the auxiliary obturator, and the movable core associated with the auxiliary obturator is mounted outside of the flow-path of the fluid.Type: ApplicationFiled: September 7, 2010Publication date: July 12, 2012Applicant: ELBI INTERNATIONAL S.P.A.Inventors: Paolo Da Pont, Giosue Capizzi, Paolo Ravedati, Maurizio Rendesi, Roberto Bosio, Massimo Davi, Fabrizio Paris
