Abstract

PURPOSE:To prevent cavitation from occurring at the time of rapid expansion, by providing a vertically movable disc valve, which acts to ensure an enough quantity of oil at the time of rapid expansion, in a damping force generator which applies a damping force only at the time of compression. CONSTITUTION:At the time of rapid expansion, a piston 5 is moved up and working oil in an oil chamber 3 is sucked because of the enlargement of a lower oil chamber 8. At that time, a disc valve 20 is moved up by (y) against a spring 24 so that the oil holes 17 of a base valve casing 12 are opened to the side of an oil hole 21 and a gap 23, the working oil in the oil chamber 3 is pushed by the pressure of gas in a gas chamber 4 and an enough quantity of oil is introduced into the oil chamber 8. As a result, cavitation is prevented. At the time of compression, the valve 20 closes the oil holes 17 so that the working oil in the chamber 8 is drained through holes 25, 21 and gaps 16a, 23 and then introduced into the oil chamber 3 through orifices 22 and gaps 14. As a result, an enough damping force is caused.
