| Disclosed is a uniaxial eccentric screw pump that can prevent the life of a bearing sliding portion from decreasing due to a thrust load applied from a high pressure side to a low pressure side. An external thread-like motor directly coupled with a driving shaft is rotated and eccentrically moved with respect to the axis of a stator to deliver a fluid from an intake side to a discharge side. The pump is provided at an end of the discharge side of the motor and extends toward the discharge side in the axial direction of the stator. The uniaxial eccentric screw pump includes an annular small-diameter portion and a seal member. The seal member is in sliding contact with the outer surface of the small-diameter portion and seals the end of a sliding portion between a self-lubricating bearing on the discharge side and the stator. | ||||||

| A rotary engine is provided that comprises a compression cylinder and combustion cylinder divided by a separation wall. Air or a fuel/air mixture is drawn into the compression cylinder, compressed, and then transferred to the combustion cylinder. The compressed air or air/fuel mixture is ignited in the combustion cylinder, creating an expansion of the combustion gases which drives the system. The compression and combustion cylinders have epicycloidal-shaped chambers that each house a single vane. The vanes pass through the crankshaft and adjust to remain in contact with the chamber walls as the crankshaft rotates. The compression ratio of the present invention can be maximized by adjusting the thicknesses of the compression and combustion cylinders as well as by offsetting the positions of the compression and combustion vanes with respect to one another. | ||||||
