Is there no "IMyAirVent" ?

Hello,

in a script I need the oxgen value and ste the pressurisation on or off.

But there is no IMyAirVent Interface?

How can I access the Airvent to get Information and set some stuff?
IN Visual Studio I use:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

using Sandbox.Common;
using Sandbox.Common.ObjectBuilders;
using Sandbox.Definitions;
using Sandbox.Engine;
using Sandbox.ModAPI.Ingame;
using...

Is there no "IMyAirVent" ?
