    Abstract: To improve the sliding rotations of pins within pin (roller) retaining holes 113a. A method of fabricating a pin (roller) retaining ring in an internal meshing gear mechanism, the mechanism having an internal gear 20 and external gears 5a, 5b put into internal mesh with the internal gear, the internal gear consisting of a pin (roller) retaining ring 110 having half-round pin (roller) retaining holes in its inner periphery and pins (rollers) 11 rotatably fitted to the respective pin retaining holes, is provided. Here, before the bore diameter &phgr;DA of a pin retaining ring base material 151 is machined to a finished diameter, the pin retaining holes 113a are cut as full round holes into the ring base material. The inner surfaces of the pin retaining holes 113a are finished by roller burnishing, and then the bore diameter of the pin retaining ring is expanded to the finished diameter to obtain the pin retaining ring having the half-round pin retaining holes. This realizes the lubrication between the pin retaining holes and the pins in a state close to fluid lubrication.

    Abstract: A rotor provided in a cylindrical rotor holding bore in a housing is supported rotatably in the holding bore via a shaft member extending coaxially with the rotor holding bore, and the rotor has one projecting portion, a gently inclined curved pressurization surface and a steeply inclined curved pressure reception surface. The rotor housing is provided therein with first and second swinging vane mechanisms positioned substantially on both sides of the shaft member, and a suction chamber, a compression chamber, a combustion chamber and an exhaust chamber, the capacities of which vary in accordance with the rotation of the rotor, are formed via these projecting portions of the rotor and first and second swinging vane mechanisms. An auxiliary combustion chamber is opened and closed by and with a first swinging vane, and a suction port is opened and closed by a second swinging vane, whereby a compressed gaseous mixture in the compression chamber is introduced into the auxiliary combustion chamber via a rotary valve in a shaft type portion of the first swinging vane and ignited therein, the auxiliary combustion chamber being then opened to inject a combustion gas into the combustion chamber.

    Abstract: A rotary internal combustion engine comprises a stator having an enclosed chamber defined by a pair of opposing side walls and a peripheral wall extending therebetween. A rotor in the chamber is rotatable by a shaft extending between the side walls. The rotor has at least one arm projecting radially from the shaft and a rotator member pivotally mounted on the end of the arm by a pivot pin. The rotator member has a working surface which spans between the side walls and has leading and trailing surfaces in contact with the peripheral wall, thereby defining a combustion chamber. Air is introduced into the chamber by at least one outlet passage which is rotatable within the chamber and opens radially, with respect to the shaft, into the chamber.

    Abstract: A high-pressure rotary fluid-displacing machine is described which is suitable for use as a motor or pump. It comprises a housing, an internally toothed annular gear, an externally toothed pinion arranged eccentrically within said annular gear and intermeshing therewith, an engagement-free crescent-shaped gap being left between the addendum circles of the pinion and of the annular gear, respectively, on the side thereof opposite the contact point of the pitch circle of the pinion with the pitch circle of the annular gear, a shaft bearing the pinion and being adapted for transmitting torque, and a gap-filling member in the gap having an inner and an outer curved surface, the inner surface being sealingly contacted by the addendum surfaces of the teeth of the pinion, and the outer surface being sealingly contacted by the addendum surfaces of the teeth of the annular gear. The housing is composed of at least two parts and has a first channel in said housing for conveying fluid medium under high-pressure therethrough and a second channel in said housing for conveying a fluid medium under lower pressure therethrough. The machine further comprises at least a first lateral plate member being adapted for closing off laterally a work space intermediate the teeth of the pinion and the teeth of the annular gear and disposed in axial direction on one side of the said pinion and annular gear, the central region of the plate member being movable wth a slight clearance relative to the pinion, and the plate member having an external rim portion clamped in between two parts of the housing, and a collar on each plate member present and projecting from the face of the latter away from the pinion and annular gear and adapted for bearing the pinion shaft therein, the housing having an internal chamber into which the collar protrudes, the internal chamber being in free communication with the first channel in the housing, whereby the plate member can be subjected to high-pressure exerted by the high-pressure fluid medium.
