<p>A one-way valve for the delivery of fluids in the gaseous or liquid state, particularly for motors and/or motor vehicle devices that comprises two coaxial members (20) forming the outer body of which one is placed on the inlet side and the other on the outlet side, and between which members (20) is inserted a diaphragm (40) provided with holes (41) distributed in a circular ring for the passage of air and an elastic membrane (50) retained on the diaphragm (40) along its perimeter and closing the said holes (41), provided with a central hole (53) corresponding to the solid part of the said diaphragm (50), the said membrane (50) being capable of deforming elastically towards the outlet member (20) to open the holes of the diaphragm (40) and allow the passage of air, the deformation being determined by the pressure gradient between the upstream and downstream sides of the valve and being limited by the contact surfaces provided on the outlet (20) member to prevent deformation and/or fracture of the said membrane (50).</p> |
