する液圧緩衝器。 A reservoir chamber filled with gas and hydraulic fluid is defined between the outer cylinder and the cylinder, and an upper fluid chamber and a lower fluid chamber filled with hydraulic fluid are defined within the cylinder by a piston fixed to a piston rod. On the other hand, the piston is provided with a damping force generating mechanism for displacing and circulating hydraulic fluid between an upper fluid chamber and a lower fluid chamber during an extension stroke and a compression stroke, and a damping force generating mechanism is provided in the piston to exchange and flow hydraulic fluid into an upper fluid chamber and a lower fluid chamber during an extension stroke and a compression stroke. In the communication passage communicating with the chamber, there is a valve that prevents hydraulic fluid from flowing out from the upper fluid chamber to the hydraulic fluid section of the reservoir chamber during the extension stroke, and prevents hydraulic fluid from flowing from the hydraulic fluid section of the reservoir chamber to the upper fluid chamber during the pressure stroke. 1. A hydraulic shock absorber, characterized in that a check valve for allowing a capacity-compensating flow of is disposed below the liquid level of the reservoir chamber.
