Title: Shock absorber and control method thereof
Inventor: ROBAATO JIEEMUSU SHIYUMITSUTO
IPC: B60G17/08
Filed: 1989-03-15
Abstract: PURPOSE: To control excessive movement of a piston by controlling the movement of the piston so that damping force generated by a shock absorber is increased in response to the movement of the piston in a pressure cylinder. CONSTITUTION: During operation, by a relatively smaller extension of a piston rod 42, the movement of a split ring 96 by which the split ring 96 can sufficiently block up a passage 80 is not produced in a groove 92. Accordingly, the flow between the upper and lower parts of an operation chamber 32 is restricted by only a piston 38. As a collar 78 is elevated until it enters a territory 36 of an inclined part 36 where reduction of the diameter is increased, the split ring 96 moves further radially in the groove 92. As a result, the split ring 96 interrupts damping fluid flowing in the passage 80.  When a collar 78 is located in a teritory of a cylinder 30, in which the split ring 96 is moved up to the range where the flow of damping fluid flowing the passage 80 is stopped, further movement of the piston rod 42 is restricted to a value at which the movent of the piston rod is permitted by compression of the damping fluid between the ring collar 78 and a rod guide 74.
