Strategyproof surplus sharing: a 2-agent characterization

A rotary piston internal combustion engine, especially of trochoidal construction which includes a piston that is rotatingly arranged on the eccentric of an eccentric shaft and rotates relative to the latter and to the housing; the engine further includes engine spaces provided on both sides of the piston hub which are sealed off by oil seals in the radially outward direction; oil is conducted out of the engine space containing a gear for the control of the piston rotation, through the piston into the opposite engine space and from there in the direction toward the lateral housing part; a shielding member is arranged between the hollow gear of the control gearing and the abutment surface at the piston, which projects into the engine space to provide a shielding effect against oil spraying and splashing out of the bearing of the piston onto the eccentric; a further shielding member which is provided in the other engine space, is secured at the end face of the eccentric and projects with a portion thereof that has a spacing with respect to the end face of the eccentric in the axial direction, over the bearing of the piston on the eccentric.
