    摘要： A pressure vibration damping device (46) in a liquid supply passage for supplying a liquid from a pump to a hydraulic device such as a fluid pressure type suspension of a vehicle, including a pressure pulse absorbing means (22) adapted to be able to accept and return a small amount of the liquid from and to said liquid supply passage so as to absorb momentary changes in the flow rate of the liquid in the liquid supply passage, and a liquid column vibration damping means (20) adapted to be able to apply a substantial flow resistance principally to a high velocity flow of the liquid in the liquid supply passage at a part thereof between the pump and the pressure pulse absorbing means, the high flow velocity being due to pulse flows of the liquid induced by a resonance of pulsating output of the pump and the pressure pulse absorbing means and substantially higher than a mean flow velocity of the liquid corresponding to a normal rate of supply of the liquid through the liquid supply passage.

    摘要： A pressure control system for suspension delivers a pressure which is proportional to a current level chosen to energize a solenoid of a pressure control valve to a shock absorber of a suspension. A change in the pressure of a return path which supplies a low pressure to the pressure control valve causes the pressure which is applied to the suspension to change. In order to suppress such change, a junction of the pressure control valve with the return path has an orifice interposed therein or is connected to a low pressure accumulator. On the other hand, in the event a depression occurs in the output of the high pressure piping, a cut valve which functions to isolate the suspension from the pressure control valve may be temporarily cut off in response to a pressure fluctuation in the high pressure piping. In order to prevent this, an orifice is interposed between the high pressure piping and a pilot chamber of the cut valve.

Each actuator is adapted to increase and decrease vehicle height as the results of the supply and the discharge of working fluid into and from its working fluid chamber, respectively. A plurality of accumulators (132, 134, 136, 138) are connected with the associated working fluid chambers. Working fluid supply passages (18) supply working fluid into the working fluid chambers and working fluid discharge passages (48) discharge working fluid from the working fluid chambers. Pressure control devices (32, 34, 36, 38) are provided in the supply passages and the discharge passages. Each pressure control device means is adapted to control the supply of the working fluid into and the discharge from the associated working fluid chamber to adjust the pressure within the chamber.

Each flow resistance control device is adapted to adjust at least one of the first flow resistance (124, 126, 128, 130) between the associated working fluid chamber and the associated accumulator and the second flow resistance of the associated discharge passage in response to the flow rate of the working fluid discharging through the discharge passage so that the higher the discharging flow rate is, the higher the ratio of the second to the first flow resistances may be, not only to reduce the flow rate of the working fluid discharging from the working fluid chamber through the discharge passage but also to increase the flow rate of the working fluid flowing into the accumulator from the working fluid chamber.

    摘要： A hydraulic control apparatus is employed in a stepless transmission in which an endless belt (60) extends between a pair of pulleys (30,32) and the velocity ratio between input (l0) and output (50) shafts is changed by varying the width of a groove defined in each of the pulleys. Hydraulic pressure supplied from a hydraulic pressure supply means (3l0) is reduced to necessary levels by first (ll0) and second (l20) adjusting means, respectively, and then sent to respective cylinder chambers (35, 45) of the pulleys. A control means (l60) controls the hydrualic pressure supply means on the basis of the higher of the output pressures of the adjusting means, so that the supply means generates a hydraulic pressure which is sufficiently high to supply the higher hydraulic pressure, thus reducing loss of power in the hydraulic pressure supply means.
