摘要： A damper (100) comprising: a cartridge (102) comprising a compression damper (104) of a shock absorber, the compression damper comprising: a single adjustable fluid circuit configured for controlling a damping rate associated with multiple compression speeds of the shock absorber, wherein the single adjustable fluid circuit comprises: a fluid passageway (322) through a base valve (112); a positionally adjustable floating shim stack (218) positioned at one end of the fluid passageway (322), the positionally adjustable floating shim stack (218) configured for selectively blocking a flow of fluid through said fluid passageway wherein said positionally adjustable floating shim stack (218) comprises: a top surface; a bottom surface; a first end (332) that remains unclamped to any other component of the compression damper (104) during a compression of said shock absorber and, upon a position adjustment of the first end such that a first component (220) of the compression damper (104) comprises a pre-load hat (220) providing a first pre-load against said top surface at said first end (332), moves a distance into the fluid passageway (322); and a second end (314) that flexes upwards when said flow of fluid through the fluid passageway (322) pushes up against said bottom surface and overcomes a predetermined stiffness of the positionally adjustable floating shim stack (218) wherein the compression damper (104) further comprises a second component (312) providing a second pre-load against the top surface at the second end (314) during an upward flexing of the second end wherein a first portion of the pre-load hat presses against the positionally adjustable floating shim stack (218), and a second portion of the pre-load hat presses against the second component (312), thereby supporting the second pre-load being applied against the top surface at the second end (314) of the positionally adjustable floating shim stack (218) during an upward flexing of the second end.

摘要： The present invention relates to a hydraulic damper (1) comprising a tube (3) and a piston assembly (4) provided with rebound valve assemblies (41r, 42r) and compression valve assemblies (41c, 42c), wherein each valve assembly comprises a deflectable-disc valve (41) and a blow-off valve (42). The piston assembly (4) comprises two sleeve-shaped members (44) each provided with a plurality of blow-off valve flow passages (442), a plurality of deflectable-disc valve flow passages (441), and a central opening (443), wherein the piston rod (5) passes through said central opening (443) to secure the piston assembly (4), a plurality of deflectable disc(s) (411) of the deflectable-disc valve (41) cover(s) said deflectable-disc valve flow passages (441), wherein a plurality of disc(s) (422, 423) of the blow-off valve (42) adjoin(s) said blow-off valve flow passages (442), wherein the piston assembly ((4) further comprises two spring seats (425) abutting said disc(s) (422, 423) of the blow-off valve (42), and at least one spring (47) disposed within said internal chamber (43) that biases said spring seats (425) towards said number of disc(s) (422, 423).

摘要： The present disclosure relates to a valve arrangement for a shock absorber. The valve arrangement (1) comprises. The valve arrangement comprises a valve housing comprising a first and a second port and a pilot chamber being in fluid communication with said first and/or second port, a pilot pressure is defined by a hydraulic pressure in said pilot chamber, a main valve member being axially movably along a longitudinal axis in said valve housing and being arranged to interact with a main valve seat of said valve housing in order to restrict a main fluid flow between said first and second ports in response to said pilot pressure acting on said main valve member. Further, the main valve member is resiliently loaded in a steady-state position from where it is movable in both directions along the longitudinal axis and is configured to, during an initial pressure increase of the main fluid, move in a direction away from the pilot chamber. The disclosure further relates to a method for controlling a damping medium flow in a shock absorber.

摘要： A damper assembly (20) comprises a housing (22) disposed on a center axis and defining a fluid chamber (28) for containing a working fluid. A piston (32) is slidably disposed in the fluid chamber (28) dividing the fluid chamber (28) into a compression chamber (34) and a rebound chamber (36). A piston rod (40) attaches to the piston (32) for moving the piston (32) in the housing (22). The piston (32) includes a first portion (42) and a second portion (44) defining a first perforation (46). An outer sleeve (148) has an exterior surface (150) and an interior surface (152) and extends between the first portion (42) and the second portion (44) covering the first perforation (46). The piston (32) includes a first entry valve (86) and a second entry valve (88) located in the piston (32) and coupled to the piston (32) for limiting the working fluid from flowing into the piston (32) with the first entry valve (86) being disposed adjacent the first portion (42) and the second entry valve (88) being disposed adjacent the second portion (44).
