Progressive Anlasseinrichtung für ein pneumatisches System

摘要

A progressive-starting unit for pneumatic circuits comprises a line inlet (112) and a line outlet (211) interconnected with each other by a regulating valve (212) that is piloted by a pneumatic piloting inlet (213). The piloting inlet is controlled by the outlet (226) of a progressive-starting device (216) having an inlet (217) connected upstream of said regulating valve (212). In this manner a progressive-starting unit is obtained which is insensitive to the conditions downstream of its line outlet.
