Publication number: 20250164078Abstract: A method for monitoring the passage of gas through a supply tube includes measuring the pressure of the gas inside a pressurized container at a first time and at a second time. The temperature of the gas is measured. A pressure difference is calculated. A temperature difference is calculated. An alarm signal is generated if the pressure difference is less than a pre-established value and the temperature difference is greater than or equal to zero.Type: ApplicationFiled: February 17, 2023Publication date: May 22, 2025Applicant: CAVAGNA GROUP S.P.A.Inventors: Matteo Compagnoni, Giancarlo Nicolini, Paolo Ragnoli

Publication number: 20250164079Abstract: A method for controlling a monitoring unit for the residual supply time for the gas present in a pressurized container includes associating with a plurality of angular positions respective residual time values in accordance with a selected flow; measuring the angular position of the control element by means of a magnetic tunnel effect angle sensor. A residual time value is determined in accordance with the selected flow corresponding to the angular position of the rotary control element; measuring an intensity of the magnetic field by means of the magnetic tunnel effect angle sensor TMR. A limit intensity value is defined for the magnetic field. A display device displays the residual time value in accordance with the selected flow only if the intensity of the magnetic field measured is less than the limit value.Type: ApplicationFiled: February 17, 2023Publication date: May 22, 2025Applicant: CAVAGNA GROUP S.P.A.Inventors: Matteo Compagnoni, Giancarlo Nicolini, Paolo Ragnoli

Patent number: 12146586Abstract: A valve assembly for pressurized containers includes a main structure, a rotary control element rotatably connected to the main structure and configured so as to allow a gas flow through the valve assembly in accordance with an angular position thereof about a main rotation axis, a detection device which includes an angular position sensor and a movable member. The angular position sensor is configured to detect the angular position of the movable member about an auxiliary rotation axis. The movable member is rotatably supported on the main structure and the angular position sensor is fixed to the main structure. The valve assembly further includes a movement conversion mechanism configured so as to convert the movement of the rotary control element about the main axis into a corresponding rotational movement of the movable member about the auxiliary axis which is different with respect to the main rotation axis.Type: GrantFiled: June 18, 2021Date of Patent: November 19, 2024Assignee: CAVAGNA GROUP S.P.A.Inventor: Giancarlo Nicolini
