Abstract: A filling valve group for a filling machine, comprising a supply duct for delivering a liquid into a container, an air return tube, and a shutter provided with a narrowing portion fixed to the supply duct and an enlarged portion fixed to the air return tube. In addition, the filling valve group comprises a centering body, which is placed at the outlet section of the supply duct to abuttingly receive the mouth of the container, and is removably fixed to a lower portion of the filling valve group by a first quick coupling. The filling valve group further comprises a fixed assembly, which forms an upper section of the supply duct, and a removable tube, which forms a lower section of the supply duct, carries fixed thereto the narrowing portion of the shutter and is removably fixed to the fixed assembly by a second quick coupling.

Abstract: An electric connector has an insulating casing defining a number of cavities for housing respective electric terminals and having axes parallel to a first direction (A) in which the connector is connected to a complementary connector; a slide fitted to the casing to slide in a second direction (B) perpendicular to the first direction (A), and having camtype first constraint means for receiving second constraint means on said complementary connector to produce a relative coupling movement between the connectors in the first direction (A) when the slide translates in the second direction (B); and an operating lever rotating about an axis (C) perpendicular to the first and second direction (A, B), and activated selectively to translate the slide in the second direction (B); the lever is hinged to the slide at the aforementioned axis (C), and actuating means are provided to move the axis (C) and the slide in the second direction (B) when the lever is operated.
