摘要： A valve (1) comprises a spring arrangement comprising a stiff (5) and a weak spring (6). The weak spring (6) has the form of a thin, circular disc having a first spring surface (6′) and a second spring surface (6′), and an inner spring part (6a) and an outer spring part (6b) substantially separated from each other with cavities (6c), yet at two points, at least, connected with legs (6d). The effect of the connection is that the outer spring part (6b) and the inner spring part (6a) can deflect in relation to each other.

摘要： A shock absorber comprises a first passage (2a, 2b) and a second passage (15) connecting a first fluid chamber (41) and a second fluid chamber (42). A throttle (12, 14) narrows an inflow of fluid to the first passage (2a, 2b) according to an applied displacement pressure. The displacement pressure includes a fluid pressure in one of the two fluid chambers (41, 42) and a pressure that depends on a velocity of the fluid flow through the throttle (12, 14). A spring (25, 29) biases the throttle (12, 14) in the opposite direction to narrow the fluid flow. The second passage (15) comprises a pair of orifices (16a, 17a). By exerting a pressure between the pair of orifices (16a, 17a) on the throttle (12, 14) in the opposite direction to narrow the fluid flow, the spring load required of the spring (25, 29) is reduced.

摘要： The invention relates to a hydraulic device comprising a tubular housing containing a rod to which a plunger is rigidly secured that separates an upper chamber and a lower chamber both filled with a hydraulic fluid, such that, as the plunger and the rod move, they move together in a relative manner axially inside the tubular housing, moving the hydraulic fluid from one chamber to the other and varying the volumes thereof. The invention also comprises a spring that operates under compression resisting the movement of the plunger in one direction when it moves toward a maximum extension position of the hydraulic device. The device also comprises an open elastic ring, the ends of which define an adjustable intermediate passage for the hydraulic fluid in order to adjust damping at the end of the maximum extension of the hydraulic device and in other relative positions.

摘要： Shock absorber used for damping a control flow which is to be directed to the control valve belonging to a hydraulic system or is to be directed to the adjustable valve of the flow through which absorber the flow of the hydraulic fluid can be directed at least in one direction. The absorber is a stopper which restricts the run of the flow to be damped which stopper is equipped with one or several ducts which let the flow go through the mentioned stopper when the other orifice of the mentioned duct is blocked with a plate in such a way that bending of the mentioned plate opens access for the flow through the mentioned stopper due to the pressure of the flow coming along the mentioned duct.

摘要： A damping force generator (40) includes: a valve body (66) having a compression-side inlet port (66c) into which the oil pushed by the piston (12) flows; and a compression-side damping valve (65) provided so as to block a port outlet and elastically deformed according to pressure of the oil flowing into the compression-side inlet port (66c) to thereby exhibit damping force. An opening cross-sectional area (A1) of a port inlet opening (79A) is larger than a passage cross-sectional area (A0) of the compression-side inlet port (66c).
