A rotor assembly for a rotary power device consists of two opposed rotor sections which when assembled in the stator of the device have limited movement parallel to the axis of rotation of the rotor assembly. Each rotor section includes through running cylinders and a center passage for a drive shaft when the sections are assembled. Each rotor section defines inwardly extending support legs and a rear face which act to limit the travel of the rotor sections towards one another. The number of support legs is equal to one half of the number of cylinders in the rotor assembly. The base of the support legs includes a socket which is aligned with a socket in the rear face of the opposing rotor section. A guide pin and spring are disposed in the socket of the support leg and the guide pin extends from the socket into the rear face socket when the rotor sections are assembled. The spring acts to normally urge the rotor sections away from one another so that the end walls of the rotor assembly are in contact with the end walls of the stator of the rotary power device. In the event of expansion of the components of the rotary power device during operation, the rotor sections can move towards one another against the urging of the spring thus avoiding excessive contact pressure between the end walls of the rotor sections and the stator.
