    • A valve system is disclosed which prevents a shrinkage or an elongation of a shock absorber in response to a compressive or tensile load applied thereto as a result of a rolling or pitching effect of a vehicle. The valve system comprises a switching valve movable among a second position in which a high pressure is introduced into an upper chamber of a shock absorber while a low pressure is introduced into a lower pressure which is separated from the upper chamber by a piston, a third position in which a low pressure is introduced into the upper chamber while a high pressure is introduced into the lower chamber, and a first position (holding position) in which the upper and the lower chamber are disconnected from a pressure source; a first and a second open/close valve which open or close a path between the switching valve on one hand and the upper and the lower chamber on the other hand; and a third open/close valve which opens or closes a path between the upper chamber and a gas spring bladder. A second mode in which the switching valve assumes its second position and the first open/close valve is enabled to pass a flow therethrough is selected in response to the compressive load. A third mode in which the switching valve assumes its third position and the second open/close valve is enabled to pass a flow therethrough while the third open/close valve is closed is selected in response to the tensile load. When neither compressive nor tensile load is applied, the first mode is selected in which the switching valve assumes its first position and the third open/close valve is enabled to pass a flow therethrough. The valve system assumes the first mode when all of the switching valve and the first, the second and the third open/close valve are deenergized.
    • 公开了一种阀系统,其防止由于车辆的滚动或俯仰效应而对其施加的压缩或拉伸载荷的减震器的收缩或伸长。 阀系统包括切换阀,其可在第二位置和第二位置之间移动,在第二位置,高压被引入减震器的上腔室中,同时将低压引入到通过活塞与上腔室分离的较低压力,第三 另外,在下部室内引入高压的同时向上部室内引入低压的位置和上部和下部室与压力源断开的第一位置(保持位置) 第一和第二打开/关闭阀,其一方面打开或关闭切换阀与另一方面的上下腔之间的路径; 以及打开或关闭上室和气弹簧囊之间的路径的第三开/关阀。 响应于压缩载荷选择第二模式,其中切换阀呈现其第二位置并且第一开/关阀能够通过其中的流动。 第三模式,其中当第三开/关阀关闭时,切换阀呈现其第三位置,并且第二打开/关闭阀能够通过其中的流动,以响应于拉伸载荷。 当不施加压缩或拉伸载荷时,选择第一模式,其中切换阀处于其第一位置,并且第三打开/关闭阀能够通过其中的流动。 当所有切换阀和第一,第二和第三打开/关闭阀都断电时,阀门系统呈现第一模式。

    • A hydraulic anti-skid apparatus which includes a cut-off valve disposed within a braking circuit connecting a master cylinder to a wheel brake cylinder, a bypass valve disposed within a bypass passage of the braking circuit, first and second pistons respectively arranged to control opening and closing operations of the cut-off valve and the bypass valve, the first and second pistons each being arranged to be applied at one end thereof with a hydraulic braking pressure from the master cylinder and at the other end thereof with a hydraulic power pressure from a fluid pump, a solenoid valve arranged to apply the power pressure to the first piston in its deactivated condition and to connect the first piston to a fluid reservoir in its activated condition, and a regulator valve arranged to control the power pressure applied to the first and second pistons in accordance with the braking pressure applied thereto. The regulator valve is arranged acts to cooperate with a check valve in response to the braking pressure thereby to produce a hydraulic pressure at a higher value than the braking pressure. An orifice element is further arranged to throttle the flow of pressurized fluid supplied to the first piston through the regulator and solenoid valves to maintain the power pressure acting on the second piston.
