FLOW PULSATOR

摘要

FIELD: generators. ^ SUBSTANCE: invention is related to generators of alternating flow and may be used in metrological certification of blood pressure and heartbeat frequency measuring devices. Flow pulsator consists of stator with outlet windows, in which detachable cylindrical hollow rotor is installed coaxially to outlet windows, being connected to motor shaft. Outlet windows of rotor n and stator m are installed in different levels and have the shape of polygons. Total number of stator windows does not exceed (n >= m) or more than (m > n) total number of rotor windows. ^ EFFECT: creation of flow pulsations with different laws of variation. ^ 2 dwg
