Abstract

421,035. Rotary engines. SULZER FRERES SOC. ANON., Winterthur, Switzerland. May 28, 1934, No. 15796. Convention date, July 7, 1933. Drawings to Specification. [Class 110 (ii)] In a rotary engine of the eccentric rotor type having four or more sliding or pivoted vanes, the spacing of the vanes around the rotor is irregular. The pitch of the vanes may increase from a minimum to a maximum several times in 360‹ and the changes may also be irregular. The angle of a blade with a radius passing through a blade root may also vary around the rotor circumference.
