Abstract
Pokrovni vijenac nepreopteretivg kola centrifugalnog ventilatora prvenstveno s kolom koje ima lopatice od ravnog ili savijenog lima unazad zakrenutima koji se sastoji od torusnog zaobljenja vijenca a na usisnom kraju i pločastog vijenca b na izlaznom kraju te krutim usisnim ušćem koje ima torusno proširenje sa zaobljenjem ana izlaznom kraju i torusno ili konično suženje ušća b od usisa do valjkastog dijela c s minimalnim poprečnim presjekom te eventualno s mirujućim diskom na valjkastom dijelu c naznačentime da se sjecište B stvarnog torusnog zaobljenja a na kolu i zamišljenog produžetka torusnogzaobljenja a na ušću nalazi na većem radiusu od sjecišta A torusnog zaobljenja a i donjeg brida lopatica kolaThe cover ring of a non-overloading circuit of a centrifugal fan primarily with a ring that has blades made of flat or bent sheet metal turned backward, consisting of a torus rounding of the ring a at the suction end and a plate ring b at the outlet end and a rigid suction mouth that has a torus extension with rounding ana at the outlet end and a torus or conical narrowing of the mouth b from the intake to the cylindrical part c with a minimal cross-section and possibly with a stationary disk on the cylindrical part c indicating that the intersection B of the actual torus rounding a on the wheel and the imaginary extension of the torus rounding a on the mouth is at a greater radius than the intersection A of the torus rounding and the lower edge of the wheel blades
