The Siemens-Halske Sh 22 (also known as SAM 22) was a nine-cylinder aircraft radial engine manufactured by Siemens & Halske in Germany in the 1930s.
Following the reorganization of its manufacturer and change in military nomenclature, the engine became known as the Bramo 322.
It was a result of a series of modifications to the original Bristol Jupiter IV design, which Siemens licensed in 1929.
Like the Jupiter, the Sh.22 featured a rather "old" looking arrangement with rather prominent valve pushrods on the front of the engine.
