摘要
A four-chamber cylinder comprises a first piston device including a first piston and a first piston rod, the first piston delimiting a first chamber and a second chamber, a second piston device including a second piston and a second piston rod aligned with the first piston rod, the second piston delimiting a third chamber and a fourth chamber, and a compressive-elastic emergency element. The first piston, via the first chamber, and the second piston, via the fourth chamber, are configured to move towards each other and held with each other to tension the compressive-elastic emergency element. With the four-chamber cylinder according to the disclosure, an actuating movement is possible via the emergency spring even in the case of a supply failure, wherein the four-chamber cylinder can be installed and operated bi-directionally.
