Abstract
Improvements in the manufacture of automatic closing valves for measuring devices that are characterized in providing the obturator with two O-rings located parallel in respective grooves made in the body of the obturator, with the particularity that between said grooves there is a transverse hole that is produced. communicates with another axial hole that begins in conjunction with said transverse hole and ends at the opposite end of such shutter, all made so that between the closed end of the obturator and the O-ring furthest from said end, a distance greater than the possible travel of the obturator between its two limit positions of open and closed.
