The disclosure provides rotary machines that include, in one embodiment, a rotatable shaft defining a central axis A, the shaft having a first end and a second end. The shaft can have a first hub disposed thereon with a plurality of cavities. At least one contour is slidably received into an arcuate cavity in an exterior surface of the hub. The contour has a convex outer surface that cooperates with an inwardly facing curved surface of a housing to form a working volume.

A pendulum slider pump may include an inner rotor connected via a plurality of pendulums to an outer rotor. The pendulums may be mounted on the outer rotor in an articulated manner, and the pendulums may respectively include a pendulum foot guiding in an associated radial groove arranged in the inner rotor. The radial grooves may each include a groove base and two circumferentially spaced groove walls. The outer rotor, the inner rotor and two pendulums adjacent in a circumferential direction may each delimit a chamber. Each pendulum foot together with the associated groove walls and the groove base may delimit a pendulum foot space. At least one pendulum foot space may be connected to the associated chamber via at least one communication channel. The at least one communication channel may open into the pendulum foot space in a region of the groove base.

A rotatory internal combustion engine includes a power module, a housing configured to retain the power module and including an intake and an exhaust, and a first sleeve including a sleeve intake, a sleeve exhaust, and an injector port. The first sleeve is removably coupleable within the housing to form an intake flow path between the housing intake and the sleeve intake, and an exhaust flow path between the housing exhaust and the sleeve exhaust. The first sleeve is interchangeable with a second sleeve that has at least one of a sleeve intake, a sleeve exhaust, and an injector port different than the corresponding sleeve intake, sleeve exhaust, and injector port of the first sleeve, and that is configured to modify at least one of a torque output of the engine, a power output of the engine, and a fuel timing of the engine, compared to the first sleeve.

A device usable as an impeller has a plurality of vanes rotating eccentrically about a shaft. Eccentric rotation is enabled by a cam mounted on the shaft. The vanes are received within slots in a rotor which surrounds the shaft and rotates about an axis coaxial with the shaft. The rotor rotates within a housing having a cylindrical surface facing the rotor. The surface is eccentric to the shaft. The vanes execute reciprocal motion upon rotation of the rotor. The vane motion is constrained so that the edges of the vanes remain proximate to the cylindrical surface during rotation.
