摘要： Provision of a fail-safe circuit which is capable of allowing a sub circuit to operate with reliability when a main circuit encounters abnormal conditions even in a system with only one supply source of pressure oil. A plurality of solenoid type control valves (3, 6) connected to an actuator (1) in parallel have centering springs respectively and are maintained at a neutral position in normal conditions. Each control valve is provided with a supply port, a return port and two actuator ports and is configured such that in the neutral position, the supply port and the return port are communicated with each other and interrupts communication with the actuator ports. And also, while the supply port (3a) of the most upstream control valve (3) is connected to a supply source (P) and the return port (6b) of the most downstream control valve (6) is connected to a tank (T), a return port (3b) of each control valve is connected a supply port (6a) of a control valve (6) located downstream from and adjacent to the connected return port (3b).

摘要： A power steering device capable of facilitating assembling thereof and eliminating a variation in elastic force acting on an input shaft of the power steering device. Leaf spring structures each of which includes a first leaf spring and a second leaf spring are arranged. The first leaf spring includes a spring-side support section constituted by a V- or U-shaped groove, a pair of rolling surface sections arranged so as to be contiguous to the spring-side support section and outwardly extend from both ends of the spring-side support section, a pair of support leg sections each arranged so as to be contiguous to each of the rolling surface sections and outwardly extend therefrom, and a pair of holding sections each arranged so as to be contiguous to each of the support leg sections and outwardly extend therefrom. The holding sections each are pressedly contacted with press contact surfaces or side surfaces of a spring receiving chamber, resulting in the first leaf spring being securely held. The second leaf spring acts to exhibit elastic force required for forcing balls or rollers against an input shaft from a rear surface of the first leaf spring.

摘要： Timer action is done from the time point t.sub.1, where the detected vehicle speed determined by the vehicle speed signal S.sub.2 is 0, until the time point t.sub.6, where the detected vehicle speed exceeds 0, thereby determining the timer time T. The value of the axle load signal S.sub.1 is transiently held, beginning at the time point t.sub.2 where the period of time X has passed since t.sub.1. When the timer time T is longer than the set timer time T.sub.0, the value of the axle load signal S.sub.1 at the time point t.sub.5, the point chronologically backward by the period of time Y from t.sub.6, is read. Based on this read value, the opening of the control valve is adjusted to vary the assist force. Thus, even when a vibration occurs in the vehicle body during driving, the assist force by the power steering system is made constant, whereby a feeling during steering can be improved.

摘要： An object of the present invention is to provide a power steering apparatus in which its neutral rigidity can be raised by applying a preset force and which is superior in its assembly performance and productivity.To attain this object, first supporting portions are formed in a pair of spring members disposed across the input shaft, and second supporting portions are formed in the input shaft so as to oppose the first supporting portions. When the input shaft and the output shaft are rotated relative to each other so that the balls or rollers are about to slip out of the first and second supporting portions, the balls or rollers roll and move while deflecting the spring members.

摘要： A power steering system with which no deterioration in steering feeling occurs when a control flow of working fluid changes. A valve mechanism V is made up of a power cylinder control valve CV for controlling a control flow Q and distributively supplying it to a power cylinder C and a bypass control valve BV connected in parallel with the cylinder control valve CV. The bypass control valve BV is normally closed, but while the control flow Q is increasing over a range of from a minimum flow Q.sub.1 to a maximum flow Q.sub.2 available for generating assist force the bypass control valve opens and returns a part of the control flow Q to a tank so that the pressure difference between the pressure chambers of the power cylinder C rises gently and the driver does not experience a disconcerting feeling such as one of the steering wheel suddenly being taken over.
