FIELD: engines and pumps.
SUBSTANCE: pump includes stator 8, rotor 6 that has axial extension 14, 16 with the possibility of movement and rotation installed, at least, partially in rotary chamber 10 of stator 8 and, at least, first and second valve between the input and rotary chamber 10 and between rotary chamber 10 and output 12 correspondingly that open and close as function of, at least, rotor 6 angular shift. The pump consists of interacting cammed elements 42, 44 at rotor 6 and stator 8 and shifting mechanism that operates at rotor 6 for force application at rotor 6 in axial direction of stator 8 cammed element.
EFFECT: invention is designed for creating an accurate and reliable pump for medical application.
