    • The present invention relates to a device in a vehicle damper which comprises a damping medium-filled damper body (2), in which an element (5, 5') forming a seal against the damper body divides the damper body into two chambers (2a, 2b). A microprocessor control unit (SU) is coupled to one or more valve and connecting arrangements (4a, 4b, 4c), comprising at least one valve and a number of flow ducts. Respective valves and flow ducts of the valve and connecting arrangement (4a, 4b, 4c) are coupled both to respective damper chambers (2a, 2b) and a pressurizing element (3) common to both of the chambers, so that even in the chamber in which a low pressure prevails there is a positive pressure acting at all times. The valve and connecting arrangements (4a, 4b) comprise a continuously electrically controlled main valve (CES), a non-return valve (SV) and one or more bleed valves (BV, 10a, 10b), the flow through the bleed valve(s) (BV, 10a, 10b) being adjustable separately from the electrically controlled main valve (CES). In the case of small strokes or slow movements the damping medium flows via the bleed valve (BV, 10a, 10b) through one or more separate leakage flow ducts. By locating the leakage flow duct(s) parallel to the valve and connecting arrangement (4a, 4b, 4c) the low-speed damping can be adjusted separately from the high-speed damping. The electrically adjustable main valve (CES) can therefore be adjusted to the correct damping characteristic whilst the damper is set up for small strokes and slow movements.
    • 本发明涉及一种车辆阻尼器中的装置,其包括阻尼介质填充阻尼体(2),其中形成对阻尼器主体的密封件的元件(5,5')将阻尼器主体分成两个腔室(2a) ,2b)。 微处理器控制单元(SU)耦合到一个或多个阀和连接装置(4a,4b,4c),其包括至少一个阀和多个流动管道。 阀和连接装置(4a,4b,4c)的各个阀和流动管道都联接到相应的阻尼室(2a,2b)和两个室共同的加压元件(3),使得即使在室 其中存在低压力,始终存在正压力。 阀和连接装置(4a,4b)包括连续电控主阀(CES),止回阀(SV)和一个或多个排气阀(BV,10a,10b),流过排放阀 (BV,10a,10b)可以与电控主阀(CES)分开调节。 在小冲程或缓慢移动的情况下,阻尼介质经由泄放阀(BV,10a,10b)流过一个或多个单独的泄漏流动管道。 通过将泄漏流动管道定位成与阀门和连接装置(4a,4b,4c)平行的低速阻尼可以与高速阻尼分开调节。 因此,电动调节主阀(CES)可以调节到正确的阻尼特性,而阻尼器设置为小冲程和缓慢运动。

The plurality of pistons of the piston assembly include at least two pistons which have respective different diameters. The freedom in connection of the hydraulic chambers of the control cylinder to the suspension cylinders can be increased by arranging the control cylinder such that the pressure-receiving surface areas which receive hydraulic pressures in all of the hydraulic chambers are equal to each other.
