A shock absorber responsive to frequency and pressure according to the present invention, which includes a cylinder filled with fluid, a piston rod conducting compression and tension strokes inside the cylinder, and a piston valve combined with the piston rod to divide the inside of the cylinder into a compression chamber and a tension chamber, comprises: a connection flow path formed in the piston rod to introduce fluid in the tension chamber inward during a tension stroke after the compression of the piston rod; a pressure valve combined with the lower end of a piston valve while being connected to the connection flow path and moving fluid in the tension chamber into the compression chamber by opening during the high-frequency stroke of the piston rod; and an auxiliary valve combined with the lower end of the pressure valve while being connected to the connection flow path and moving the fluid in the compression chamber into the compression chamber by opening during the low-frequency stroke of the piston rod. |
