FIELD: physics, instrumentation technology.
SUBSTANCE: invention is meant for liquid metering devices. Right- and left-threaded helical rotors are installed in a meter body; the rotors having reciprocally enveloped teeth profile. The rotors have the same profile and are machined with the same tool. Inside part of helical rotor tooth has epycycloid form. The opposite side of rotor tooth is formed by two circular arcs and Archimedian spiral. Purpose of the invention is rotor mass decrease and simplification of their production process. Suggested rotor profile ensures increase of measurement chamber net volume.
EFFECT: simplification of rotor production process and increase of measurement chamber net volume.
