Abstract
An expander (M) employing steam as a working medium is formed from a first radially inner group of axial piston cylinders () arranged annularly on a rotor () so as to surround the axis (L) of an output shaft (), and a second radially outer group of axial piston cylinders () arranged annularly so as to surround the first group of axial piston cylinders (). The first and second groups of axial piston cylinders () are driven by a common swash plate (), and the first and second groups of axial piston cylinders () are arranged with circumferentially displaced pitches. High-temperature, high-pressure steam firstly operates the first group of axial piston cylinders (), then operates the second group of axial piston cylinders (), and the outputs from the two are combined to drive the output shaft (). This achieves a further reduction in the size and a further increase in the output of the axial type expander (M).
