Oil Pump: Original Rotor Tooth Profile
Utilizing its original tooth profile design technology, YAMADA provides oil pumps that meet various customer requirements such as reduced noise, reduced cavitation, and increased efficiency, and so on.
The sound quality was improved from a noise that sticks in the ear to a sound that is difficult to hear by making the pump's oil pressure pulse irregular.
Equalizing the pressure inside the rotor cell during the pump's intake process reduced cavitation.
Giving the rotor a smaller diameter while keeping the same theoretical discharge volume and rotor thickness with the conventional trochoid tooth profile's reduced pump friction.
Applying YAMADA's original tooth profile, it is possible to reduce the size while maintaining the pump capacity.
