Abstract

PURPOSE:To make the damping characteristic of the shock alsorber variable and provide a cushion comfortable to ride by opening or closing an orifice formed on a hollow rod through a cylindrical space displaced in accordance with the contraction of a suspension spring. CONSTITUTION:At the time of compressing operation where an inner tube 2 moves into an outer tube 1 while compressing springs 10 and 11, an oil chamber B contracts in accordance with the rise of a piston 3, and a part of the working oil within the oil chamber B flows into an oil chamber C. Surplus oil corresponding to the entering part of the tube 2 flows into an oil chamber C through a damping valve 9 or an orifice 14. Thereafter, when the stroke increases and the orifice is closed by a spacer 12, the working oil flows into the oil chamber A only through the damping valve 9. Accordingly, the damping characteristic of the initial stroke it depends only on the orifice 14, and in the succeeding intermediate and after strokes, a damping force based on the damping valve 9 is obtained, and a cushion comfortable to ride can be obtained.
