Beschreibung
Zusammenfassung:	A valve comprising a valve body having an outflow pipe and comprising a valve seat which defines a first zone of the outflow pipe upstream of the valve seat and a second zone downstream of the valve seat, and a cam follower which is capable of moving with respect to the valve seat along an axis X between an open position, at least one partially open position and a closed position, and comprising a valve head which is capable of moving into abutment in a fluid-tight manner against an abutment surface of the valve seat, a rod which is fixedly joined to the valve head, in such a manner that there is defined a through-opening between a lateral surface of the rod and a corresponding internal surface of the valve seat which faces the lateral surface of the rod, characterized in that the through-opening is equal to a first value A when the cam follower is in the at least one partially open position and is equal to a second value B when the cam follower is in an open position, with B>A.
