    • PURPOSE:To enable the response performance to be augmented by configurating a car shock absorber in such a manner that the cross sectional area of the oil passage which connects two hydraulic chambers within a cylinder is allowed to be adjustable permitting a piezoelectric element to generate an electric voltage in response to the displacement of sliding members and also to transmit the displacement to the sliding members simultaneously. CONSTITUTION:A side hole 18 of a piston 12 is connected with a groove 19a of a spool 19 permitting a damping force determined by the resistance caused through the side hole 18 and a throttle 16 to be produced when no electric voltage is applied to a piezoelectric element 23 by a control circuit 2. While on the contrary, when a high voltage is applied to the piezoe lectric element 23 by the control circuit 2, a small change in elongation takes place in the piezoelectric element 23 allowing its displacement to be enlarged by a ratio of the cross sectional area between a plunger 25 and a projection 19b of the spool 19 by a sealed chamber 27. This causes the spool 19 to be displaced downward allowing the side hole 18 and the groove 19a to be disconnected. Resultantly, this allows the damping force to be increased. In addition, changes in hydraulic pressure 14 and 15 when a car is running are allowed to be converted into changes in an electric voltage of the piezoelectric crystal element 23 by the piezoelectric effect, and to be transmitted to the control circuit 2 to determine the running condition. Thus, this configuration enables the response performance to be augmented.
    • 目的:为了通过配置汽车减震器来实现响应性能的提高,使得能够使连接气缸内的两个液压室的油路的横截面面积被调节,从而允许压电元件产生电 响应于滑动构件的位移的电压以及同时将位移传递到滑动构件。 构成:活塞12的侧孔18与卷轴19的槽19a连接,允许在不对电压施加电压时产生由通过侧孔18产生的阻力和节流阀16产生的阻尼力 相反,当通过控制电路2向压电元件23施加高电压时,在压电元件23中发生较小的伸长变化,从而允许其位移通过 通过密封室27的柱塞25和柱塞19的突起19b之间的横截面积的比率。这使得线轴19向下移位,允许侧孔18和凹槽19a断开。 因此,这样可以增加阻尼力。 此外,当汽车行驶时,液压14和15的变化允许通过压电效应转换为压电晶体元件23的电压变化,并被传送到控制电路2以确定运行 条件。 因此,该配置使得能够增强响应性能。

    • PURPOSE: To reduce the fluctuation in the flow rate of a single pumping chamber, by providing the cross section of the inside circumferential surface of a cam ring with a form made by synthesizing a sine wave with a wave three times higher in frequency than the sine wave, at a prescribed ratio.
      CONSTITUTION: A pump with thirty-three cylinders comprises three eccentric cam rings 30 and eleven vanes 20. The cross section of the inside circumferential surface of the cam ring 30 is provided with a form which is made by synthesizing a sine wave with a wave three times higher in frequency than the sine wave, at an appropriate ratio, and accords to a formula R(θ)=a+(b/2)×{1+(9sin3θ+N×sin9θ)/(9-N)} where R(θ) denotes the distance between the center of gyration of a rotor 40 and the inside circumferential surface of the cam ring 30, a and b constants, and N an optional number within a range of 0.4≤N≤1.2. As a result, the fluctuation in the flow rate of a suction port is very much reduced.
