A rotary engine, pump or compressor with a intake/exhaust ports in end plates and a rotatably mounted block mounted in a framework. In an embodiment cylinder sets are mounted in the block and each includes opposing cylinders with ends which include transfer ports disposed to alternately form passage

A rotary engine, pump or compressor with a intake/exhaust ports in end plates and a rotatably mounted block mounted in a framework. In an embodiment cylinder sets are mounted in the block and each includes opposing cylinders with ends which include transfer ports disposed to alternately form passageways with the intake and exhaust ports as the cylinders rotate with the block. A novel crankset operatively connects the block to the driveshaft.
