Patent number: 11279194Abstract: A damper with a main damper assembly includes a damper tube with a damping fluid. A main working piston divides a main fluid chamber into a piston rod side and a non-piston rod side. The main fluid chamber has an upper zone, a lower zone and a mid-zone. A secondary damper assembly with a secondary working piston is in fluid communication with the main damper assembly. When the main working piston travels in the mid-zone, fluid is caused to pass through the main working piston and the secondary working piston to generate a first damping force and when the main working piston travels in either of the upper and lower zone, fluid is caused to pass only through the main working piston to generate a second damping force, wherein the first damping force is less than the second damping force.Type: GrantFiled: April 2, 2020Date of Patent: March 22, 2022Assignees: THYSSENKRUPP BILSTEIN OF AMERICA INC., THYSSENKRUPP AGInventors: Alexander Dixon, Bill Bryant, Chad Smith, Clayton Kantner
