Description:
Application: Pump and ventilator. This was first exhibited as a ventilator by Evrard in the Belgian department of the 1867 Paris exhibition. The contact of the two wheels has the excellent characteristic that the tops of the teeth of the grooved wheel roll upon the root circle of the other wheel, without sliding. The grooved surfaces are of curtate epitrochoid section while the flanks of the extended teeth are cardioidal. (H. Roehl, c. 1950) (cardioid: a one-cusped epicycloid)
