Pneumatic spring-damper unit for automobile has damping spaces defined within cylinder housing by piston unit with 2 separation pistons and spring space defined by rolled bellows around projecting piston rod

摘要

The spring-damper unit has a cylinder housing (1) containing a piston unit (8) with at least 2 separation pistons (10,11) fitted to a piston rod (9), the section of the piston projecting from the cylinder housing enclosed by a rolled bellows (19), with damping spaces (12,13,14,15) defined by the separation pistons within the cylinder housing and a spring space (22) defined by the rolled bellows.
