A rotary machine is described with a vane carried by a rotor in a housing. The vane includes: a central vane axis extending radially outward along a y-axis from a center of the rotor through the vane to the housing. A centrifugal force of the vane against the housing is primarily distributed with a first sealing element mounted on an end of the vane, such as a rotatable element supported by a rigid support. The rigid structure of the first sealing element facilitates use of a second flexible sealing element mounted on the vane end. The second flexible sealing element performs as a sliding seal between a trailing expansion chamber and a leading expansion chamber on opposite sides of the vane. The rigid seal and the flexible sliding seal typically function independently of each other as separate constituents of the tip or end of a given vane.
