Abstract:
A support for an eccentric of an adjusting arrangement of a connecting rod has a piston rod (18) guided by a piston (20). A seal (24) is connected to the piston (20) in a supporting cylinder (12, 14) in the connecting rod (2) and has a longitudinal axis (16). The piston (20) encloses a chamber (22) with the supporting cylinder (12, 14). The piston (20) has a lower part (30) arranged on an upper part (28) for movement along the axis (17) of the supporting cylinder (12, 14). An expanding ring (40) between the upper and lower parts (28, 30) interacts with faces (42, 44) of the lower part (30). The upper part (28) spreads the expanding ring (40) as the spacing between the faces (42, 44) is reduced, and the expanding ring (40) applies a friction force FR on an inner wall (46) of the supporting cylinder.
