Abstract

A device to dampen hydraulic vibrations (10) with independent position and speed. Will be provided The hydraulic damping device (10) has the piston valve (22) firmly fixed to the far end of the piston rod (11), the base tongue (27) and the hopper cavity (15). ) The base valve (27) will have a tube channel on the compression side (31). The first coil spring (28) will be provided between the first valve (24) and the base valve (27) and the second coil spring. (23) shall be provided between the first valve (24) and the piston valve (22). The compression side pipe (31) shall be closed by the first valve (24) near the time of the The second valve (33) passing through the middle of the first valve (24) and the base valve (27) is used. Pressure Equal to or greater than the pre-set pressure of the oil cavity (21b) to adjust the flow rate of Oil liquid to the chamber cavity (15)

Of the piston rod; The outer barrel that covers the outer perimeter of the barrel; Retention cavity, which has a space between the inner perimeter of the outer cylinder and The perimeter of the cylinder and where oil and gas are encapsulated; Bottom stop that crystallizes the bottom part of the cylinder outside from the outside; Base tongue fixed by butt stop and with first compression channel and funnel. The second compression side connects the lower and storage cavity; The first tongue fixed by the base tongue through the first whirlpool; A second spiral spring held by the first tongue, which is set up between the first tongue. And the piston valve, which causes the force to drive downward when the piston valve is pressed and that closes the first compression channel by pressing the first valve downward against the thrust of the spiral spring. The first; And the second tongue that is arranged in a condition where the second tongue passes through the center of the first tongue and The base valve and to adjust the flow rate of the oil compared to the cavity that holds the pressure of the cavity. The bottom of the barrel becomes equal to or higher than the pre-determined level due to the outer load ---------- 1. Hydraulic damper that is composed of: cylinder; Oil to be added to the barrel in such a way that it is encapsulated and that will form an oil cavity in the barrel; Piston rods that move back and forth in the oil cavity; A firmly fixed piston tongue to the end of the piston rod, separating the oil cavity into Upper and lower oil cavity And to move back and forth in a way that touches Sliding type with the inner periphery of the cylinder, which is synchronized by movement Back and forth of the piston rod; The outer barrel that covers the outer perimeter of the barrel; The chamber cavity, which provides a space between the inner perimeter of the outer cylinder and The perimeter of the cylinder and where oil and gas are encapsulated; Bottom stop that crystallizes the bottom part of the cylinder outside from the outside; Base tongue fixed by the bottom stopper and with the first compression pipe and tube cavity. On the second compression side, the lower oil cavity and the expansion tank are connected; The first tongue fixed by the base tongue through the first whirlpool; A second spiral spring held by the first tongue, which is set up between the first tongue. And the piston valve, which causes the force to drive downward when subjected to the compression of the piston valve and to close the pipe on the first compression side by pressing the first valve downward against the force that is constantly exerted. of The first spiral spring; And the second tongue that is arranged in a condition where the second tongue passes through the center of the first tongue and Base valve and to adjust the flow rate of oil compared with the chamber cavity when the pressure of the oil cavity. The bottom of the barrel is equal to or above the pre-determined level due to the outer load. 2.
