Abstract

See full text

In the rotary type cylinder device, a first crank shaft is revolved around a shaft and a composite piston assembly is revolved around the first crank shaft in a state where first rotational mass balance relating to first and second piston units around second virtual crank shafts, second rotational mass balance relating to the composite piston assembly around the first crank shaft and third rotational mass balance relating to the first crank shaft and the composite piston assembly around the shaft are uniformly produced by only first and second balance weights which are attached to end parts of the first crank shaft. Therefore, first and second piston units, which are attached to the second cylindrical sections, are linearly reciprocally moved in radial directions of a circular orbit of second virtual crank shafts, which has radius of 2 r, with relatively revolving around the shaft.
