MAGNETIC COMPASS Russian patent published in 1996 - IPC

FIELD: navigation means. SUBSTANCE: magnetic compass has case filled with fluid, magneto-sensitive element put on supporting device including column with support holder located in cavity of lower part of magneto- sensitive element. Tail part of column with support holder is brought out- side of cavity through hole in base of magneto-sensitive element forming bottom of cavity. Column with support holder has nonmagnetic elastic forming bottom of cavity. Column with support holder has nonmagnetic elastic washer which diameter exceeds that of through hole in base of magnet-sensitive element and is determined by dependance D (1.2-1.5)d, where D is outer diameter of elastic washer, d is diameter of through hole in base of magneto-sensitive element. Outer diameter of elastic washer and its position on column of support holder are determined by dependence , where α is angle of free inclination of magneto-sensitive element; r=D/2 is outer radius of elastic washer; R is radius of internal cavity of magneto-sensitive element; H is distance from point of support of magneto-sensitive element to lower plane of elastic washer. EFFECT: enhanced operational stability. 4 dwg
