Abstract
The object of the present invention is to provide a fluid rotary machine in which dead spaces can be reduced as much as possible even if the machine is enlarged by arranging rotary valves directly behind cylinder chambers. The fluid rotary machine in which first and second double-headed pistons () intersecting within a case body () move linearly back and forth within cylinders () due to the hypocycloid principle along with rotation of shafts () and in which intake and exhaust cycles are repeated in chambers (), wherein cylinder heads () for closing the cylinder chambers () are each provided with rotary valves () which are rotated by drive transmission from the shafts () and which are provided with intake holes and discharge holes () alternately communicated with the cylinder chambers () via communication channels (), and the rotary valves () intersect longitudinal axis of the opposing pistons () and are capable of rotating parallel with output axil lines.
