The spring cartridge is formed of a spring with upper and lower support zones formed by the respective ends of the spring in a plane perpendicular to its axis, and between which is formed a compression zone with the central section which has biconical structure. Truncated cone shaped upper support zone and lower support zone are formed in spring compression zone. Thus, spring coils at the upper and lower support zones have the same radii and turn into first coils of smaller bases of truncated cones of upper and lower transient sections respectively. First spring coils of bigger bases of upper and lower transient sections turn into upper and lower coils of central section respectively. |
