It is never pulling. In the case where it would be pulling the second oil circuit (not drawn by scarbs) is working in compression thus preventing that the first oil circuit increases its volume. Front and rear heave pistons are completely restrained in oil circuits (dual acting cylinders, equal piston surfaces).xpensive wrote:Don't think it matters mep, you can't use hydraulics for pulling, that's all there is to it really.
I still believe the image is a single acting cylinder with means to adjust the hydraulic volume and thus the front ride-height.
Possible is that the device in the picture is just there to maintain a certain pressure in the system. Basically working as accumulator. Interesting to notice is the relative high diameter of the cylinder and the geometry of the spring. The interlinked suspension cylinders I have seen so far are tinny compared to that.
