摘要： During either of the extension and compression strokes, hydraulic liquid flows from a cylinder upper chamber into a reservoir through an annular passage and a damping force control mechanism, and a damping force is generated by the damping force control mechanism. The check valve is provided with a sub-check valve in parallel thereto, which opens in a very low piston speed region to allow the hydraulic liquid to flow through an orifice passage. These check valves are opened successively as the piston speed increases, thereby generating a sufficiently small damping force in the very low piston speed region during the compression stroke of the piston rod, and obtaining a moderate damping force when the piston speed increases.

摘要： [Object]The present invention provides a suspension control apparatus that allows miniaturization of a solenoid valve.[Solution]When a controller is started up by a power source controller (a power source unit), the controller switches a control current from 0 ampere to a maximum current value I6 at the same time as the startup. After that, the control shifts to normal control. As a result, even if a hysteresis of a damping force characteristic is large relative to the control current, it is possible to promptly move a solenoid valve to a position to be used in the normal control.

摘要： A damping force adjustable hydraulic shock absorber, in which response delay of a pressure control valve and self-excited vibration of a valve body can be prevented. A damping force is generated by controlling an oil flow between an annular oil passage (21) and a reservoir (4) generated by sliding movement of a piston in a cylinder with use of a back-pressure type main valve (27) and a pressure control valve (28). The damping force is directly generated by the pressure control valve, and valve-opening pressure of the main valve is adjusted by adjusting an inner pressure of a back-pressure chamber. In the pressure control valve, a valve spring is disposed between a valve body and a plunger. A mass of the valve body is sufficiently less than that of the plunger, and a spring stiffness of the valve spring is higher than that of a plunger spring.

摘要： A fluid pressure shock absorber in which valve opening of the main valve is controlled by an inner pressure of a backpressure chamber. A first piston (3) and a second piston (4) coupled to a piston rod (10) are fitted in a cylinder (2) such that a piston chamber (2C) is defined between the first and second pistons. An extension-side main valve (18) and a compression-side main valve (23) are provided in the piston chamber (2C). Valve opening of the main valves is controlled by an extension-side backpressure chamber (19) and a compression-side backpressure chamber (24). A compression-side check valve (13) and an extension-side check valve (16) are provided at the first piston (3) and the second piston (4). During an extension stroke of the piston rod (10), the compression-side check valve (13) is closed, whereby action of a pressure of a cylinder upper chamber (2A) on the compression-side main valve (23) is prevented. During a compression stroke of the piston rod (10), the extension-side check valve (16) is closed, whereby action of a pressure of a cylinder lower chamber (2B) on the extension-side main valve (18) is prevented. Accordingly, it is possible to generate a stable damping force, and enhance durability of the extension-side main valve (18) and the compression-side main valve (23).

摘要： Provided is a suspension apparatus capable of preventing excessive increase in damping force due to a sudden input from the road surface when the damping force is adjusted to a minimum value during running. A damping force control type hydraulic shock absorber (1) includes a damping force adjusting valve (25) which adjusts a damping force by a current supplied to a pressure control valve for controlling a pilot pressure. A control device (ECU) outputs a minimum control current I=0.5 A to cause the damping force control type hydraulic shock absorber (1) to generate a minimum damping force. When the minimum control current is supplied, the pressure control valve of the damping force adjusting valve (25) is always opened. Thus, an increase of the damping force caused by a rapid increase of the pilot pressure due to the sudden input from the road surface is suppressed.
摘要翻译：提供一种悬架装置，其能够防止在行驶中将阻尼力调整为最小值时，由路面突然输入引起的阻尼力的过度增加。阻尼力控制型液压缓冲器（1）包括阻尼力调节阀（25），该阻尼力调节阀（25）通过提供给用于控制先导压力的压力控制阀的电流来调节阻尼力。控制装置（ECU）输出最小控制电流I = 0.5A以使阻尼力控制型液压缓冲器（1）产生最小阻尼力。当提供最小控制电流时，阻尼力调节阀（25）的压力控制阀总是打开。因此，由于由路面的突然输入引起的先导压力的迅速增加而引起的阻尼力的增加被抑制。

摘要： A first piston and a second piston coupled to a piston rod are fitted in a cylinder, and an intermediate chamber is formed between the first and second pistons. A compression-side check valve and an extension-side check valve are provided at the first piston and the second piston. An extension-side main valve and a compression-side main valve are disposed in the intermediate chamber. A downstream side of a damping force adjusting valve is connected to the intermediate chamber. Inner pressures of an extension-side backpressure chamber and a compression-side backpressure chamber are adjusted by the damping force adjusting valve, whereby valve opening of the extension-side and compression-side main valves is controlled. Hydraulic fluid of the downstream side of the damping force adjusting valve is first sent into the intermediate chamber, and then is sent to a cylinder upper chamber or a cylinder lower chamber. Due to this arrangement, it is possible to prevent a sudden drastic change in a hydraulic fluid pressure and thereby to generate a stable damping force.
