Abstract:
A control valve including: a valve body, a flow shutter operatively interposed between an inlet and an outlet, a driving spindle having at least a first actuating end and a second end connected to the flow shutter. The valve also includes a differential pressure automatic regulation device, comprising: a cup-shaped body arranged around the driving spindle and axially mobile with respect to said driving spindle; a spring operatively interposed between the valve body and the cup-shaped body to push the latter away from the flow shutter; a rolling membrane having a radially inner edge fixed to the cup-shaped body and a radially outer edge fixed to the valve body to delimit a first chamber in fluid communication with the inlet and a second chamber in fluid communication with the outlet.

Claim (Index 39):
A control valve comprising:\n a valve body including an inlet, an outlet and a flow passage extending from the inlet to the outlet; a flow shutter in the flow passage and between the inlet and the outlet, wherein the flow shutter includes an inlet opening facing the inlet of the valve body and an outlet opening facing a cup-shaped body; a driving spindle mounted in the valve body and extending perpendicular to a centerline of the flow passage, wherein the driving spindle includes a first actuating end and a second end opposite the first actuating end, wherein the second end is connected to the flow shutter; a shutter mounted to the driving spindle and facing towards the outlet opening of the flow shutter, and a differential pressure automatic regulation device comprising:\n the cup-shaped body coaxial with and extending around the driving spindle and configured to move axially in the valve body with respect to the driving spindle; \n a coil spring between the valve body and the cup-shaped body, being coaxial to the cup shaped body, and biasing the cup-shaped body away from the flow shutter; and \n an annular rolling membrane having a radially inner edge fixed to the cup-shaped body and a radially outer edge fixed to the valve body, wherein the annular rolling member separates a first chamber which is in fluid communication with the inlet from a second chamber which is in fluid communication with the outlet.
