摘要： A brake reaction which occurs as a brake booster is actuated is prevented from being transmitted to a brake pedal, and instead pseudoction reaction imparting means 41 is provided to transmit a pseudo-reaction to the brake pedal. A valve body 5 and a power piston 3 are capable of relative movement in the axial direction, and are normally urged away from each other by a spring 8. The valve body 5 is normally urged forward by a spring 42 which is disposed within the variable pressure chamber B. This arrangement allows a variation in the advancing stroke of the brake pedal to be suppressed small if a variation occurs in the magnitude of a negative pressure which is introduced into a constant pressure chamber A as the brake booster is actuated, thus providing an improved brake feeling experienced by a driver.

摘要： A booster 3 has a structure that a return valve 14 is formed into a two-step throttle incorporating a first throttle valve 36 and a second throttle valve 37 formed continuously from the first throttle valve 36. When a valve spool 28 has been moved forwards when the operation is performed, a gap of the first throttle valve 36 is reduced. Also a gap of the second throttle valve 37 is reduced. Therefore, hydraulic fluid discharged from a pump is passed through an inlet passage 12, and then introduced into the second annular groove 13. Then, the hydraulic fluid is throttled by the first throttle valve 36, and then throttled by the second throttle valve 37. That is, the hydraulic fluid is throttled in the two-step throttling manner. As a result of the two-step throttling structure, the overall velocity of the flow of the hydraulic fluid can smoothly be changed without rapid change. Therefore, fluid flow noise caused from the change in the velocity of the flow can be prevented.
摘要翻译：增压器3具有将止回阀14形成为具有从第一节流阀36连续形成的第一节流阀36和第二节流阀37的两级节气门的结构。当阀芯28向前移动时，执行操作，第一节流阀36的间隙减小。此外，第二节流阀37的间隙也减小。因此，从泵排出的液压流体通过入口通道12，然后被引入到第二环形槽13中。然后，液压流体被第一节流阀36节流，然后被第二节流阀37节流。也就是说，液压油以两段节流方式节流。作为两级节流结构的结果，可以平稳地改变液压流体的总体速度而不需要快速变化。因此，可以防止由流动速度的变化引起的流体流动噪声。

摘要： If a determination is made by a pressure gradient comparison means 24 that gradient of the rise in the pressure in an accumulator calculated by a pressure gradient calculating means 21 and realized during the operation of a pump is lower than a predetermined level, occurrence of an abnormal condition of the pump or a motor is determined. If a pressure gradient comparison means 24 determines that the gradient of pressure depression of the hydraulic pressure in the accumulator realized after the operation of the pump has been interrupted is higher than a predetermined value, occurrence of an abnormal condition which is leakage of solution is determined. If determination of the abnormal condition is sequentially made predetermined number of times, an abnormal-condition deciding means 28 decides occurrence of an abnormal condition, and then produces an output to an alarm-signal generating means 29.

摘要： In a brake system, when a braking force tends to be insufficient, a first switching valve is set at an interrupting position to render a control chamber in a sealed state, and a pump is actuated to render a supplemental pressure-regulating valve in operation. Thus, MCY pressure supplied to a port of the supplemental pressure-regulating valve is increased to move a supplemental pressure piston downwardly to close the supplemental pressure-regulating valve. The fluid pressure from the pump is supplied to a brake cylinder to increase the braking force. In this manner, a supplemental braking control is provided to ensure the braking even when the braking force tends to be insufficient. The system can be made simple.

摘要： In a brake booster system of the present invention, just after a MCY produces MCY pressure Pi according to the pedal pressure of a brake pedal, a valve piston of a pressure-intensifying valve moves so that a valve portion is seated in a rubber valve seat. In addition, a pedal switch detects the pedaling of the brake pedal to drive a motor and a pressure-intensifying pump. Therefore, W/C pressure Po of a W/C is intensified by the discharge pressure of the pressure-intensifying pump. The intensified W/C pressure Po causes the upward movement of a stepped piston of a pedal stroke shortening cylinder. The brake fluid is transferred toward the MCY corresponding to the movement of the stepped piston, thereby restricting the stroke of the piston of the MCY and thus shortening the pedal stroke of the brake pedal.
摘要翻译：在本发明的制动助力系统中，刚刚在MCY根据制动踏板的踏板压力产生MCY压力Pi之后，增压阀的活塞阀移动，使得阀部分位于橡胶阀座。此外，踏板开关检测制动踏板的踏板以驱动马达和增压泵。因此，W / C的W / C压力Po被加压泵的排出压力增强。增强的W / C压力Po导致踏板冲程缩短缸的阶梯式活塞的向上运动。制动液朝向与阶梯式活塞的运动相对应的MCY传递，由此限制了MCY的活塞行程，从而缩短了制动踏板的踏板行程。

摘要： In a brake-pressure producing device of the present invention, a power piston 10 of a hydraulic booster 2 comprises a stepped piston including a large-diameter portion 10a on which fluid pressure of a power chamber 30 is exerted and a small-diameter portion 10b having the same diameter as the master cylinder piston 53. Both the pistons 10, 53 are interlocked with each other through an aligning rod 62. The pressurized fluid of the power chamber 30 is introduced into an annular chamber 51 formed on the circumference of the small-diameter portion 10b and the fluid pressure of the pressurized fluid is exerted on a stepped portion 10c between the large-diameter portion 10a and the small-diameter portion 10b in the direction opposite to the direction of the fluid pressure of the power chamber 30. When the braking operation is performed, the fluid pressure in the power chamber 30 introduced into wheel cylinders 33, 34 relating to one of the circuits and the master cylinder pressure introduced into wheel cylinders 58, 59 relating to the other circuit balance to be equal to each other, thereby uniformly and properly distributing braking forces to the respective wheel cylinders.

摘要： According to the invention, a first spring abutment which extends radially outward is formed on a valve plunger, which forms part of a reaction mechanism for brake booster. A second spring abutment which extends radially outward is formed on a plate plunger. A plurality of coiled springs are disposed in parallel across the pair of spring abutments, and a brake reaction is transmitted to the valve plunger through the plate plunger, the second spring abutment, the plurality of the coiled springs and the first spring abutment. With this construction, the plurality of coiled springs which are disposed in parallel provide a combined spring constant, which is given as a sum of spring constants of individual coiled springs, whereby a combined spring constant of an increased magnitude can be obtained. This allows a servo ratio of the brake booster while the plurality of coiled springs are being compressed to be freely chosen as compared with the prior art.

摘要： According to the invention, the booster is not provided with a brake reaction transmission mechanism, and hence a reaction cannot be transmitted to a brake pedal. On the other hand, a pseudo-reaction imparting means is provided to impart a pseudo-reaction of suitable magnitude which depends on the degree of depression of the brake pedal. The pseudo-reaction imparting means is arranged so that when the brake pedal is depressed relatively rapidly, a relatively smaller braking reaction is imparted than during a usual depression. With this arrangement, the transmission of an abnormally high braking reaction to a driver which is experienced in a conventional booster during a quick braking operation due to an operational rag of the booster is avoided. The pseudo-reaction imparting means allows a reaction of a suitable magnitude which depends on the rate of depression of the brake pedal by a driver to be imparted, thus permitting a high output to be obtained with a reduced force of depression during a quick braking operation.
摘要翻译：根据本发明，增压器不设置制动反作用传动机构，因此反作用力不能传递到制动踏板。另一方面，提供了伪反应赋予装置，以提供取决于制动踏板的压下程度的适当大小的伪反应。假反应赋予装置被布置成使得当制动踏板相对较快地被压下时，施加比在通常的凹陷期间相对较小的制动反作用。通过这种布置，避免了由于加速器的操作性破坏而在快速制动操作期间在常规助力器中经历的驾驶员异常高的制动反应的传递。伪反应赋予装置允许通过驾驶员施加的取决于制动踏板的下压速率的适当大小的反应，从而允许在快速制动操作期间以减小的压力获得高输出。

摘要： A valve plunger, which forms part of a reaction mechanism of a brake booster, comprises a plunger member and a valve side member which are disposed to be slidable relative to each other, with a first spring disposed therebetween. A piston is slidably disposed within a valve body, and a given clearance is formed between the rear end face of the plunger member and the piston. A second spring having a greater resilience than the first spring is disposed between the piston and the valve body, and is compressed after the first spring is initially compressed. With this construction, as a brake reaction increases, the first spring is compressed to cause the plunger member to abut against the piston, and subsequently the first and second spring are compressed. A point where the compression of the first spring is initiated can determine a point where a servo ratio is changed, and the magnitudes of the resilience of the both springs permit an arbitrary choice of a servo ratio which prevails subsequent to the point where the servo ratio is changed.
