Flodman's valve-gear
Klug's valve-gear drawing
Flodman's valve-gear has a horizontal eccentric rod suspended in a pendulum and it works the same as the Klug's valve-gear, but the pendulum and the link to the slide valve rod have swaped places. However, the mechanism that moves the pendulums suspension point, is quite differently.
Flodman's valve-gear seems to be most used on Swedish steam engines.

The steamships prow machinery has a Klug's valve-gear. It is slightly modified; the characteristic curved rod to the slide valve rod is replaced by a straight one.
