Abstract

The hydraulic damping cylinder has an outer oil cylinder (1) in a housing (2) and an inner oil cylinder (3) with a piston strut (4) and a valve seat (5) with a valve housing and spring (7). In the middle of the axle hole is a strut (42) which moves against the piston strut and the valve seat. An oil well (51) has a concave surface (52) and a forcing ball (53) and exit (421) and the edge of the valve seat has several oil oil exits (54).
