On the reciprocating bane of a reciprocating vane type rotary internal combustion engine (vane engine), big centrifugal force is generated by a high-speed rotation and is opposed to combustion pressure, and force equal to or more than seal action force to be necessary for vanes tip is added to the case inside, and friction loss becomes big. For get the force to support centrifugal force and to make this friction loss small, a vane tip cross-section vertical to a rotating axis is formed in a pick-shaped so as to generate gas bearing action force greatly. In addition, in order to raise a hydrostatic pressure in neighborhood of tangent line of both the outside curved surface of vanes tip and the case inside, and to get the multiplication effect that raise a hydrodynamic pressure in the vanes tip, gas supply hole is established parallel to the rotating axis in the midsection of the vanes tip. Therein, porous matrix or great many minute holes connect between the gas supply hole and outside curved surface of the vanes tip. High pressure air, combustion pressure gas or steam is provided to gas supply hole, then, it is spouting out from outside curved surface of it, and get a high hydrostatic pressure and raise a hydrodynamic pressure. Furthermore, because there is not the first steam for lubrication searing in a start, steam reservoir and pressurization pump is established. Therein, compress the air in the steam reservoir by press-fitting water in steam reservoir, then it is used to lubrication searing. After an engine began to move in start or activation, till pressure of revitalization vapor by exhaust becomes proper, as method to get the high pressure gas for lubrication searing, part of the combustion gas which is pulled out from the second steam supply-cum-combustion gas pulling out port, which established a little to the bottom dead point from the center point of the front side vane toward rotating, this vane which combustion chamber pressure of this engine, in which continued fuel injection and combustion (make the best use of characteristic of this engine), become maximum, is connected with the first steam supply pipe for lubrication searing through a filter and a check valve. Fuel injection in neighborhood of the top dead point is difficult to avoid the surface of a wall adhesion, because combustion chamber is so flat. As substitute for it, I devised a method to do vaporization of fuel or injection on the part which close late of air supply port near the bottom dead point, so as to vaporized or injected fuel mix with supply air without loss and so as not to join the air to pass without dropping in.
