Abstract: A valve for adjusting the air flow rate in an internal combustion engine; the valve presents: a valve body; a cylindrical tubular pipe obtained within the valve body and in which an air introduction channel is defined; a valve seat obtained along the air introduction channel of the tubular pipe; an actuation system; a shutter, mobile under the bias of the actuation system; and a connection flange, which is integral with a first end of the tubular pipe and presents a plurality of through holes which are crossed in use by corresponding fastening screws for rigidly fixing the valve body; the connection flange is provided with a lower plate and an upper plate, which are reciprocally parallel, facing and distanced and are arranged radially with respect to the cylindrical tubular pipe, and a number of ribs, which reciprocally connect the plates, are arranged perpendicularly to the plates, and are arranged axially with respect to the cylindrical tubular pipe.

Abstract: An acquisition system for detecting the angular position of a gas knob of a motorcycle; the acquisition system is provided with: a fixed supporting body; a mobile element, which is mounted mobile in the supporting body; a transmission device, mechanically connected to the gas knob and to the mobile element for transmitting the motion from the gas knob to the mobile element itself; and a main position sensor, which is carried by the supporting body, is coupled to the mobile element for determining the angular position of the mobile element, and is designed to provide two mutually redundant measurements of the angular position of the mobile element.
