Patent claims

1. A hydraulic two-way acting damper (1), comprising a damper housing (Ia) in which a piston (14) is arranged, which functions in and divides a damping medium-filled damping chamber (12) into two sub-chambers (12a, 12b), which are connected together by at least one damping duct (13), in which, basically in the middle of the piston (14), there is a space (17), in which a second end (16b) of a second arm (16) rotating about its first end (16a) is arranged, and in which the first end (16a) of the second arm (16) is also firmly coupled, via a first pin (15) that extends basically outwards at right angles from the longitudinal direction of the damper housing (Ia), to a first arm (11) connected to a non-rotating fixed part

(9), characterized in that the space (17) is pressurized to a pressure greater than atmospheric pressure in that a pressure reservoir (19) is arranged on or in the damper housing (Ia) and is connected to the pressurized space (18) via a duct (22) .

2. The hydraulic damper as claimed in claim 1, characterized in that the piston (14) is divided into two parts (14b, 14c), where further damping ducts

(14d), which connect the two sub-chambers (12a and 12b) to one another via the space (17) between the piston parts (14b, 14c), is arranged in each piston part (14b,

14c) .

3. The hydraulic damper as claimed in claim 2, characterized in that there are two, three or more ducts (14d) placed in a circle around the center line of the piston (14) inside an outer diameter (dy) .

4. The hydraulic damper as claimed in claim 2 or 3, characterized in that a leaf valve in the form of a thin, flexible washer (26) with an outside diameter (Dy) is designed to extend over the ducts (14d) on the outer area of the piston.

5. The hydraulic damper as claimed in claim 4, characterized in that the flexible washer (26) is arranged at a distance (x) from the piston, so that a gap is formed between the washer and the piston part (14a/14b) .

6. The hydraulic damper as claimed in claim 5, characterized in that the distance (x) is defined by the thickness of a rigid washer (27) located tight against the outer area of each piston part (14b, 14c).

7. The hydraulic damper as claimed in any one of the preceding claims, characterized in that the damping chamber (12), the pressure reservoir (19) and the damping duct (13) are defined by circular milled-out sections and/or bored channels in the damper housing (Ia) .

8. The hydraulic damper as claimed in any one of the preceding claims, characterized in that the pressure reservoir (19) is arranged parallel to the damping chamber (12) .

9. The hydraulic damper as claimed in any one of the preceding claims, characterized in that the damper

(1) is designed to damp movements between a vehicle handlebars (5) and its non-rotating part in the form of a frame or chassis (9) .

10. The hydraulic damper as claimed in claim 9, characterized in that the damper (1) is adapted to different types of vehicle with different maximum steering angles (α) between the vehicle handlebars (5) and its frame/chassis (9) without varying the stroke

(S) of the damper (1), that is to say the maximum moving distance of the piston (14), in that the length (L) of the second rotating arm (16) is adjusted according to the formula L = S / 2* sinα.
