<p>A hydraulic shock absorber includes an inner cylinder (2) filled with a working oil, an outer cylinder (3), and a reservoir (4) defined between the inner and outer cylinders. A piston (5) is slidably disposed within the inner cylinder so as to divide the interior of the inner cylinder into an upper cylinder chamber and a lower cylinder chamber. A piston rod (6) is connected to the piston. A tubular member (13) is disposed between the inner and outer cylinders and has a radial port (27, 29). A damper mechanism (43) is attached to the outer cylinder so as to control the flow of the working oil to produce a damping resistance. The outer cylinder includes a mounting projection (31) with a substantially flat top surface (33) on which the damper mechanism is secured. A sleeve (39, 41) has one end inserted into the port of the tubular member and the other, flanged end (39a, 41a) terminating at the top surface of the mounting projection. A first sealing element (71, 77) is secured between the sleeve and the port to provide a seal between the sleeve and the tubular member. A second sealing element (73, 79) is secured between the flanged end of the sleeve and the top surface of the mounting projection. A third sealing element (75, 81) is secured between the flanged end of the sleeve and the casing of the damper mechanism. <IMAGE></p> |
