Description of the Invention: [Technical Field] The present invention relates to a stepless variable pressure shock absorber, which particularly refers to a stepless variable pressure shock absorber with adjustable variable buffer pressure. [Prior Art] The shock absorber mainly uses a speed compression or stretching shock absorber' to dampen vibration and impact by the damping effect generated by the resistance generated by the shock absorber. Even the elastic element bed and chair used in daily life. Its elastic components are also broadly classified as a shock absorber. However, the shock absorbers generally referred to are usually, but not limited to, used in various types of vehicles, mechanical equipment and earthquake resistance of houses. Referring to the sixth figure, the prior art shock absorber (2) includes a cylinder block (21), and the cylinder block (21) is internally provided with a pressing rod (22), and the bottom of the pressing rod (22) A damping valve (23) is formed. The damping valve (23) forms a first chamber (24) and a second chamber (25) that define a portion of the cylinder (21) to be accommodated by a damping fluid. And the damping valve (23) is provided with two venting holes (26)'. When the pressing rod (22) is subjected to vibration or impact to press the damping© valve (23), the second chamber (25) The damping fluid is turbulent from the second chamber (25) through the venting opening (26) to the first chamber (24). The damping valve (23) is used to buffer the mutual impedance of the damping fluid in the second chamber (25). Since the cross-section of the damping valve (23) of the prior art is substantially equal in outer diameter, when the damping valve (23) is in each of the pressing processes, if the diameter of the boring hole (26) is much smaller than the damping The cross section of the valve (23), the damping fluid will accumulate in an instant, and the damping fluid can not adapt to the domain formation resistance, so that the buffer shock absorption effect is greatly reduced. If the aperture of the declaration hole (26) is much larger than the section of the damping valve (23), the resistance 201020416 is quickly discharged with almost no resistance, so how to seek a balanced and appropriate modulation 'for such suspension The design and manufacturer of the device should be considered. SUMMARY OF THE INVENTION In view of the problems of the prior art, the present inventors have devised a stepless type of shock absorber, a type of stepless variable pressure shock absorber comprising a pressure cylinder having a partition inside the cylinder The plate is delimited to a first chamber that can be accommodated by the damping fluid and a second chamber

Due to the transverse fineness of the first perforation, the inner edge of the first perforation and the outer edge of the pressing rod are guided by the downward pressure when the utility rod is moved and gradually pressed down. The perforation clearance changes, so that the calendar rod produces different yang effects through the first rider's (such as different degrees of support). Therefore, the present invention can be used for the vibration of a single size, and produces different yang effects and slow _ red sue, while the area of the thief of the rope is gradually converged from top to bottom (for example, slanting, gradually arcing, etc.). There is no obvious segment change, so it is called segmental pressure shock absorber." 4 201020416 [Embodiment] The construction, features, and embodiments of the present invention will be described in the following, and the reviewer will be able to understand the present invention. Referring to the first and second figures, the present invention relates to a stepless type of wishing shock absorber which can be used, for example, for various types of vehicles, mechanical equipment, and earthquake resistance of houses. The main body of the invention comprises a pressure siphon body (1), the inside of which is formed by a partition 1) as a boundary. The cylinder body (1) is internally formed - a first chamber (12) for damping fluid to be accommodated The second chamber (13) 'The damping fluid can be selected from various suitable oils, gases, liquids, and the like. The inner cylinder (1) is internally provided with a pressing rod (14), and the top of the pressing rod (14) can be combined with a vehicle, a machine or a house for shock and shock absorption. The partition (11) is provided with a first through hole (15) for allowing the pressing rod (4) to reciprocate inside the first chamber (12) and the second chamber (10) via the first through hole (15). When the conjugate formed by the pressing rod (14) is vibrated, the pressing rod (14^) generates a pressing and returning action. Further, the bottom of the second chamber (10) is provided with a -impedance sheet (10) (please cooperate with the third figure). The present month is in the pressing; ^(丨4) is provided with a damping 阙 ((4)) in the first chamber (10), and the damping 阙 (141) can be used for pressing the damping fluid in the first chamber (10), and The pressure-reducing fluid may cause the first perforation (15) to enter the second chamber (10), thereby forcing the impedance) UUTF to 'because the flow of the fluid and the shock to produce a cushioning effect. The characteristic of this creation is that the cross-sectional area of the pressed Na) gradually converges from top to bottom. 5 201020416 It is worth saying _ is 'Because the cross-sectional area of the first perforation (15) is fixed, when the pressing rod (14) is gradually pressed by the vibration and passes through the first perforation (15), the pressing The rod (14) causes a change in the perforation clearance from the inner edge of the first perforated crucible 5) and the outer edge of the pressing rod (14) due to the lower portion. By "recess", the original cross-sectional area of the first perforation (15) is subtracted from the cross-sectional area of the pressing rod (14), that is, the damping fluid in the first chamber (12) can flow to the second The remaining diameter of the chamber (13). The clearance will change as the pressing rod (14) gradually goes up and down, and the upper and lower extents of the pressing rod (14) are changed by the magnitude of the vibration until the pressing rod (14) passes the first When perforated (15), it will also be subjected to different degrees of crowding to produce different damping effects. Therefore, the present invention can produce different damping effects and buffering shock effects for different magnitudes of vibration, and the cross-sectional area of the pressing rod (14) gradually converges from top to bottom (for example, gradually inclined or gradually orphaned). Wait). Since there is no obvious change in the position of the segment, it is called "the stepless transformer shock absorber j°. Please refer to the third figure. The partition plate (11) of the present invention is further provided with a second perforation (11 1). 4 and 5, a portion of the second perforation (111) is provided with a chamber (112). A ball valve (U3) is disposed in the chamber (112), and the ball valve (113) is located at the first volume. In the chamber (12), the chamber (112) is connected to a mesh cover (114) having a mesh. The pressing rod (14) is gradually pressed down when subjected to vibration, and is located in the first chamber. The damping fluid in (12) flows through the first perforation (15). It should also be partially flowable from the mesh and the second perforation (111), but because the ball valve (113) will be closed due to weight sinking. The second perforation (in) ' thus causes the second perforation (111) to act without damping the damping fluid when the pressing rod (14) is depressed. However, when the pressing rod (14) is raised, the second chamber ( The damping fluid in 13) can flow from the first perforation (15) to the first chamber (12) except for the 201020416, and the ball valve (113) will also float due to the damping fluid. Order The second perforation (m) is opened to assist the flow of the damping fluid from the second chamber (13) to the first chamber (I). Further, the first side of the cylinder (1) of the present invention is provided with a first outer side. Resisting the component (17), and the pressing rod (14) is provided with a second resisting member (18) at an outer edge of the upper position, and a first resisting member (Π) is disposed between the first resisting member (18) and the second resisting member (18) The elastic member (19) can provide a better shock absorbing effect. The invention also has a soft body (142) (such as rubber, dream rubber, etc.) disposed between the damping valve (141) and the top of the cylinder block (1). Further, the shock between the damping valve (141) and the top of the red body (1) can be further reduced, and the damping fluid can be prevented from leaking out to provide a sealing effect. In summary, the present invention is in line with industrial utilization. Sexuality, and not seen before the application, is not known to the public and has a non-obvious knowledge. The patentable element 'is patented according to law. ▲ In a preferred embodiment of the industry of the present invention, all of the equivalent changes of the patent patent bribe are claimed in the present invention. 201020416 [Simplified illustration of the drawings] The first drawing is a perspective view of the present invention.
