Abstract
A loading device for installation of rotary engine oil sealing rings into paired concentric circular grooves in a rotor end face comprising an annular sleeve having an inside diameter equal to the outside diameter of the radially inner groove and an outside diameter equal to the inside diameter of the radially outer groove, which sleeve rests upon the rotor end face in the annular surface area between the two grooves. The sleeve has a pair of generally radially facing inner and outer conical surfaces converging axially outwardly of the rotor for gradual loading of the resilient elastomeric static oil seals during axial installation thereof into the respective grooves.
