    • A housing of a brake booster 100 includes a pair of shells 1 and 5 and a ring 3 interposed therebetween which cooperatively define an interior space for accommodating a power piston 13. The interior space is divided into a front chamber 15 and a rear chamber 16 partitioned by the power piston 13. The power piston 13 has a diaphragm 2 interposed between the front chamber 15 and the rear chamber 16. The diaphragm 2 is shiftable in an axial direction thereof in response to pressure imbalance between the front chamber 15 and the rear chamber 16. A convolution chamber 2d is provided between an inner side of the housing and an outer peripheral edge of the diaphragm 2. The convolution chamber 2d is defined by a resilient annular member flattened in the axial direction and isolated from both the front chamber 15 and the rear chamber 16. The annular member elastically rolls along the inner side of the housing in response to pressure imbalance between the convolution chamber 2d and one of the front 15 and rear chambers 16. And, a port 28 is formed in the ring 3 to supply constant pressure into the convolution chamber 2b.

    • For regenerating an exhaust gas particulate collecting filter, there is provided an exhaust gas particulate purifying process in which damage to the filter caused by a thermal action can be prevented and further electric power can be saved when an electric current supply to an electric heater attached to the filter is controlled. In the filter container (4), an electric heater (21) is provided on an end surface of the filter on an upstream side with respect to a regenerating gas flow, or provided at a position close to the end surface. Also, a temperature sensor (22) for measuring a temperature of the filter is provided inside the filter or at a position close to an end surface of the filter opposite to the aforementioned end surface. Further, there is provided a first controller (13) for determining an appropriate current amount to be supplied to the electric heater and also for determined an electric power reducing pattern used in the case of stoppage of power supply, in accordance With the filter preheating temperature immediately before the start of regeneration detected by the temperature sensor (22). A second controller ( 17) controls a current amount supplied to the electric heater (21) in accordance with a command given by the first controller (13).
    • 为了再生废气微粒收集过滤器,提供了一种废气微粒净化过程,其中可以防止由热作用引起的过滤器损坏,并且当向连接到 过滤器被控制。 在过滤器容器(4)中,电动加热器(21)相对于再生气体流在上游侧设置在过滤器的端面上,或设置在靠近端面的位置。 此外,用于测量过滤器的温度的温度传感器(22)设置在过滤器的内部或靠近与前述端面相反的过滤器端面的位置处。 此外,提供了一种第一控制器(13),用于根据过滤器预热温度来确定要供应到电加热器的适当电流量,并且还确定在停止供电的情况下使用的减电模式 在由温度传感器(22)检测到的再生开始之前。 第二控制器(17)根据第一控制器(13)给出的命令来控制提供给电加热器(21)的电流量。
