せしめる減衰力調整装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention is a damping force adjusting device for a hydraulic shock absorber, specifically a piston or bottom pulp having both valve members that generate damping force during compression and expansion, respectively. This invention relates to a damping force adjustment device that allows a fixed square hole provided to act only on either compression or expansion.

った。Conventionally, in a piston or bottom pulp that has both valve members that generate damping force during compression and expansion, respectively, fixed square holes are arranged in parallel in the piston or bottom pulp,
Although it has been attempted to adjust the damping force during the compression stroke or the extension stroke, it has not been possible to adjust only one of each. For example, when a piston or the like is provided with a fixed square hole to obtain the necessary damping force during the compression stroke, there is a drawback that the square hole also affects the damping force during the extension stroke.

うにしたもので従来公知でβる。No. 11 is a cross-sectional view of an embodiment of the damping force adjusting device of the present invention, and is conveniently used in a rear cushion type piston section.
A piston 3 fitted at the tip of the piston 3 is slidably fitted into a cylinder 4 filled with oil, and a coil spring 6 is stretched between the implanted base 5 of the piston rod 2 and the cylinder 4. It is a hydraulic damper 4+Ttj, and damping force can be obtained during the compression stroke and extension stroke by the oil hole 7.8 provided in the piston 3 and the valve member 9.10. Although the explanation will be omitted, the damping force during the extension stroke can be reduced, and is known in the art.

連通する油孔７と連結せしめるようにしたものである。Therefore, in the present invention, as shown in the enlarged view of FIG. 2 in detail, a fixed square hole 11 is provided in the steel stone 3 to generate a damping force at this time, and the fixed square hole 11 is opened and closed. The check pulp 12 opens only during the compression stroke to generate a damping force (low speed), and when the speed reaches the high speed range, hydraulic pressure presses the check pulp spring in the valve part 10 to generate damping force as before. That is, a fixed square hole 11 is provided through a check pulp 12 in the portion of the lower seating surface of the piston 3 that is in contact with the valve member 10, and communicates with the upper oil chamber A through an oil passage 13. The piston 3 is connected to the oil hole 8 through the check pulp 12 on the other hand.
The oil hole 7 communicating with the lower oil chamber B is connected to the oil hole 7 by a groove (not shown) provided in the lower island surface of the oil chamber B.

することＫなる。In this way, in the low speed range during the compression stroke, the oil in the upper oil chamber A opens the check pulp 12 via the oil hole 8 - oil passage 13 - fixed square hole 11, and the piston 3 The oil flows through the groove in the lower seat surface to the oil hole 7 and then to the lower oil chamber B, generating a damping force at low speeds. Subsequently, when the vehicle enters a high-speed range, the oil presses the check valve spring of the valve member 10 to generate a force at high speed and a damping force. On the other hand, during expansion, the fixed square hole 111 is closed by the check pulp 12, so that conventional damping force is generated only by the pulp.
この実施例では、圧縮行程時のみに発生する固定二乗孔

を逆にすればよい。In this embodiment, a fixed square hole is described that occurs only during the compression stroke, but in order to cause it to occur only during the opposite extension stroke, the opening and closing of the check pulp provided in connection with the fixed square hole may be reversed.
