The inventions relate to rotary machines provided with nonparallel axes of a rotor and pistons.The inventive positive-displacement rotary machine comprises a body, the working surface of which is embodied in the form of a part of a segment of sphere, a rotor (7) which is provided with a working surface of revolution and which is arranged in the body in such a way that it is rotatable, a ring-shaped concentric working cavity formed by the body and the rotor (7), a separator which is embodied in the form of a wobble plate, is fixedly arranged in the body and divides the working cavity into two parts. The working surface of the rotor (7) is provided with at least one groove which is embodied along the geometrical axis of rotation thereof and in which a piston (8) in the form of a part of disk is placed in such a way that it is enabled to perform rotational oscillations in the plane thereof. Each piston (8) is provided with a sealable slit for the separator passage. At least one through passage (42), which makes it possible to position input (12) and output (13) ports on the opposite sides of the separator by mutually spacing them along the axis of the rotor (7), is embodied on one of the areas of the separator, thereby simplifying the combination of stages. Said inventions make it possible to increase the synchronising reliability of the working members of a spherical machine and to use it in a bottom-hole high-speed multistage high-pressure pump.
