A residual pressure holding valve () for a hydropneumatic suspension strut () of a motor vehicle has a valve housing () with an air inlet () and an air outlet (). A valve body () is arranged displaceably in the valve housing () and a valve element () is arranged displaceably in the valve body (). Air pressure applied to the air inlet () can lift the valve body () off a valve body seat () of the valve housing () to allow air to flow past the valve body () to the air outlet (). Air pressure applied to the air outlet () can lift the valve element () off a valve element seat () of the valve body () to allow air to flow past the valve element () to the air inlet ().
