The outer tube unit comprises an outer tube, an outer tube unit, and a piston. The outer tube has an outer tube wall M326598 and an installation space defined by the outer tube wall and extending axially. . The piston ^ ^ ^ ^ ^ ^ # ^ ^ ^ ^ ^ ^ ^ ^ ^ ^___ ^ f ^ ^ .ht S # ^ ^ # # ^ ^ ^ ^ # ^ ^ ^ ϋ ^ ^ r ^ ^ t ^ ^ S,, ^ ^ t, ^ ^ ^ Stream % circle with one hit ring. The piston partitions the installation space into a first space portion, and a first space portion 'and the piston includes a connecting portion adjacent to the second space portion of the diameter expansion μ fe m ^ j. i, and a recess a guide groove on the diameter expansion section and the connecting section. The bleed ring is annularly disposed on the condensing section and has a first annular surface facing the radial expansion section, and at least one concave concave extending radially inward from an outer circumference of the first annular surface groove. The retaining ring is correspondingly sleeved on the connecting section and closely fits the outer wall. When subjected to an external force, the piston unit moves axially relative to the outer tube unit to reduce the volume of the first space portion, and the liquid inside thereof is pressed and flows to the second space portion via the groove and the guide groove. The structure of the above piston unit is different from the previous innovative design, and the groove of the piston and the groove of the discharge ring can make the flow of the liquid smoother. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments. 6 M326598 A ginseng 'w straw is installed by a fixing device 8 on a predetermined material such as the door panel 9 soil to make the surface yang 9 reach the buffer or shock absorption. The damper includes: - the outer tube unit 2 'and a piston unit 3. In addition to the present embodiment, the tube unit 2 has a hollow outer portion 4, and a sealing seat 23 which is fixedly coupled to the first oil seal 21 and the L second oil seal 22 at the top end of the outer tube 4. Wherein, the outer tube 4 is of a design with one end closed at one end, the open end of which is oriented and disposed in the fixing device 8, the closed end is exposed to the fixing device 8, and the outer tube 4 has a center axis and An outer tube wall 41 having an inner wall surface 411 and an installation space 4 defined by the outer tube wall 41 and extending axially. Referring to Figures 2, 3 and 4, the piston unit 3 is mounted in the outer tube 4 and includes a piston whose tip passes through the first oil seal 21 and the second oil seal 22 and projects upwardly from the top end of the outer tube 4. a rod 3 1 , a piston 5 fixed to the bottom end of the piston rod 3 , and a bleed ring 6 and a 擒 ring on the piston 5 are axially slidable The piston 5 is inserted into the installation space 4 of the outer tube 4 in synchronization with the piston rod 31, and the installation space 40 is partitioned into a first space portion 401 located below. And a second space portion 402 located above, and the space portions 401, 402 are respectively filled with liquid, and the piston 5 includes a circular diameter expansion portion 51 located at an upper portion adjacent to the annihilation seal seat 23, and an interval The bundled section 52, which is pinched below the section 51, has a connecting section 53' which is connected between the radial section 5丨 and the bundled section M32659852, and a guide groove 54 which is recessed. Wherein the diameter expansion section S1 includes a connecting surface 53 to the surface 511 4 including a first connection connecting the first - 531, ^ ^ ^ ^ ^ f ^ # 53 ^ # ^ ^ ^ 52 of the radial expansion surface mi In the portion 532, the guide groove 54 is recessed from the radial outer circumference of the radial expansion surface, and is recessed inwardly and then axially extended and recessed on the first connecting jaw 531. The diameter of the piston 5 of the present embodiment is a stepwise change, that is, the diameter of the diameter expansion section 51 is the largest and slightly smaller than the inner diameter of the outer tube wall, and the diameter of the first connection portion 531 is smaller than the diameter. The diameter of the first connecting portion 532 is smaller than the diameter of the first connecting portion 531, and the diameter of the narrowing portion 52 is the smallest. The venting ring 6 is annularly disposed on the condensing section 52, and the ring 6 and the piston 5 of the embodiment are separately formed and reassembled. In actual implementation, the flow ring 6 can also have the same a first annular surface 61 surrounding a central axis and facing the radial expansion 51, a second annular surface 62 disposed opposite to the first annular surface 61, and a radial outer periphery connecting the first annular surfaces 61, 62 A connecting ring surface 63, and a groove 64 spaced from the first ring surface 01 toward the second ring surface 62. Wherein the diameter of the connecting ring surface 63 is smaller than the inner length of the outer tube wall 41, so that the connecting ring surface 没有 does not fit the inner wall surface 411 of the outer tube 4, and the grooves 64 are equal. The angular interval is radially inwardly extended from the radially outer periphery of the first annular surface 6b, and the broadcast ring 7 is disposed at the thickness of the connecting portion 5 of the piston 5 and the drain ring M326598 6 and Including a ^ H 71 facing the radial expansion 51, a fourth annular surface facing the discharge collar 6, a radial inner peripheral connection 4' connecting the 'second two' faces 71, 72, etc. Therefore, the outer connecting surface of the radially outer periphery of the four-ring surface 7], 72 is 74 ^ ^ m 73 ^ - ft 53 ^ } 74 41 Therefore, the outer connecting surface 74 and the inner wall surface 411 of the outer tube 4 are in close contact. When the time is used, when the outer and the first plug 3 are moved axially downward relative to the outer tube unit 2, ^ ^ ^ ^ ^ ^ 401 ^ ^ ^ ^ ^ ^ ^ ^ flows to the second space Port 4〇2, the liquid will flow upward through the gap between the (four) walls 41, and then flow to the second portion through the inner connecting surface 73 of the support ring 7 and the 5 53 5 缝隙 gap, which will cause an upward flow due to the upward flow of the liquid Pushing the force of the retaining ring 7 and engaging the expanding surface 511 (as shown in FIG. 4) may block the flow of the liquid, but the guiding groove 54 is slidably disposed on the connecting portion 51 and the connecting portion. Therefore, the third < face 71 Zhao will be completely close to the _ surface 5 2 ( (four), even if the 7 is placed against the _ 51 'liquid ^ ^ the second space part 402 ^ Λ * the foreign official 4 is subject to the upward When the external force of the crucible disappears, the liquid is no longer subject to ^ ^ 401 > ^ 8# 3 2 Φ] ±^ 9 M326598 The liquid flows downwards. Similarly, the liquid flows downward due to the downward flow of the liquid. Pushing down, so that the fourth torus is attached to the first surface 61 of the bubble ring 6, and may block the flow of the liquid, but because the first surface 61 of the crucible is provided with the concave 64, so even if the retaining ring 7 abuts against the shallow loop, the liquid can flow to the grooves 64, and then flows downward through the gap between the venting ring 6 and the outer tube wall 41 to the first space portion. 4〇ι .. 〇> The above description shows that the present invention is active in an innovative design, and the arrangement of the groove 54 of the piston 5 and the groove 64 of the bleed ring 6 can make the flow of the liquid It is smoother. By providing such a different structure of dampers, it will enable the consumer to have more diverse choices, and promote the purchase of gas and enhance the development of the industry. The preferred embodiments are not intended to limit the scope of the present invention, that is, the simple equivalent changes and modifications made in accordance with the scope of the present invention and the novel description are still within the scope of the present patent.
