IPC: F04B39/12
Filed: 1978-04-27
Abstract: PURPOSE: To reduce the occurrence of noise, by forming a step on the welded joint of an upper and a lower cover by differentiating their diameters and thereby easily increasing the stiffness of their side walls.  
     CONSTITUTION: The radius of lower cover B of cylindrical shape, which is fitted with a bottom, is made larger by the thickness l of the plate than that of upper cover A. Joining flanges 4 and 5 are provided on the edges of the openings of upper cover A and lower cover B. In this condition, they are welded together. By this, when upper and lower covers A and B are placed with their centers lying on their same axis, a step of the thickness l of the plate is formed between side wall 6 of upper cover A and side wall 7 of lower cover B. As a result, the neutral surface with respect to the bending in the container passes through the part removed from the center of the thickness l of the plate, so that the stiffness, which is the cross- section secondary moment, increases. At the same time, the resonant frequency increases, which interferes with the oscillation produced inside, so that noise is reduced.
