In an intake valve for air spring suspensions of truck cabins, the suspension is adapted to connect first and second mechanical elements with possibility of mutual movement and includes a variable volume chamber containing air; elastic element arranged between the mechanical elements; an intake valve for inflow of air into the chamber; an exhaust valve for outflow of air from the chamber. The intake valve includes: a valve body provided with an axial duct including an air inlet and outlet ports; an operating mechanism of the valve, including a piston and a spring. The piston includes a rod and a head and is arranged inside the valve body so vertical movement of its rod, in cooperation with the outlet port of the axial duct, defines a cross section area for air flow inside the chamber. |
