Abstract (en)
Device for delivering several fluid media in a certain volume ratio with metering cylinders, a movable piston in each of them, which pistons are interconnected. There is a two-way switch valve with a control mechanism, depending on the piston position. Each switch valve has a pressure medium inlet, a medium outlet and two overflow channels, each connected to the cylinder part volume. Due to the fact that the pistons are also connected to an energy storage device which is charged during the stroke of the pistons and has sufficient capacity to supply the energy needed to switch over the switch valves, the device is entirely independent of any external energy source for its functioning. <IMAGE>
