Publication number: 20200378511Abstract: A pressure relief valve includes a first port that receives a first gas at an input pressure, a second port that receive a second gas at a regulating pressure, a third port in communication with the first port via an orifice and that outputs the first gas at an output pressure and a piston movable along an axis and configured to control the passage of gas through the orifice between the first port and the second port, such that the output pressure of the gas is dependent on the axial position of the piston. The valve also in include a resilient member configured to bias the piston and the valve comprises a chamber at least partly defined by the piston and in fluid communication with the second port, such that the force exerted by the gas within the chamber on the piston acts against the action of the resilient member.Type: ApplicationFiled: December 12, 2019Publication date: December 3, 2020Inventors: Giacomo MEZZINO, Domenico TAFUNI, Andrea MORNACCHI

Publication number: 20200370560Abstract: An apparatus for use in a gas turbine engine is disclosed comprising a bleed valve and an intermediate valve. In use the bleed valve is exposed to a source of pressurised air, and the bleed valve is movable between an open position, in which the bleed valve permits a flow of the pressurised air through the bleed valve and a closed position, in which the bleed valve does not permit a flow of the pressurised air through the bleed valve. The intermediate valve is operatively connected to the bleed valve and configured to selectively open and close the bleed valve, wherein the intermediate valve is configured in a mode of operation to close the bleed valve based on the pressurised air within the bleed valve exceeding a predetermined threshold.Type: ApplicationFiled: December 12, 2019Publication date: November 26, 2020Inventors: Giacomo Mezzino, Gianfranco Salvatoriello

Patent number: 10801528Abstract: An actuator includes an actuator piston movable along an axis, a first stop member rotatable about the axis and configured to limit the movement of the actuator piston in a first direction along the axis, a second stop member movable along the axis and configured to limit the movement of the actuator piston in a second direction along the axis, wherein the first direction is opposite to the second direction. A first screw connection is present between the first stop member and the second stop member such that rotation of the first stop member about the axis causes movement of the second stop member along the axis to vary the amount by which the actuator piston can move along the axis in use.Type: GrantFiled: March 1, 2019Date of Patent: October 13, 2020Assignee: MICROTECNICA S.R.L.Inventors: Giacomo Mezzino, Enrico Quaglia
