ABSTRACT An oil seal for rotary piston internal com- bustion engines, and method of making the same, com- prising a spacer-spring disposed in a circular groove in the rotary pi ton end face, and a pair of annular oil scraping rails radially spaced from each other within the groove and urged into sealing engagement with the rotor housing end wall by the spacer-spring. The spring includes a pair of circular concentric bands which rest upon the groove root, and a plurality of circumferentially spaced struts connecting the bands and acting to space the rails from each other against respective groove side walls. A plurality of cir- cumferentially spaced spring legs extend from each of the circular bands generally radially across the groove to engage the radially opposite oil scraping rail and urge the rail against the housing end wall. i.
