摘要： An improved brake actuator, particularly an improved sealed service chamber, having a flexible tubular seal affixed at one end in the central pushrod opening in sealed relation and surrounding the pushrod in sealed relation in the service chamber housing. The improved seal is generally hourglass-shaped including a midportion which closely circumscribes the pushrod in sealed relation and a free end portion which closely circumscribes the pushrod. A relatively inflexible generally diamond-shaped washer surrounds the midportion of the seal which improves sealing, assures concentricity of the tubular seal, prevents the seal from being pushed through the pushrod opening and provides for easy assembly of the seal and washer assembly in the service chamber around the pushrod. The improved end wall of the service chamber housing includes an offset recessed central portion surrounding the mounting bolts and relatively thin preferably V-shaped contact surfaces which generally circumscribe the recessed portion. The contact surfaces are drawn tightly against the mounting bracket as the nuts on the mounting bolts are torqued against the mounting bracket, significantly reducing vibration between the end wall of the service chamber and the mounting bracket.
摘要翻译：一种改进的制动器致动器，特别是改进的密封操作室，具有柔性管状密封件，其一端以密封的关系固定在中心推杆开口中，并以密封的关系围绕推杆围绕在操作室壳体中。改进的密封件通常是沙漏形的，包括紧密地围绕推杆密封的中间部分和紧密地围绕推杆的自由端部分。相对不弯曲的通常为菱形的垫圈围绕密封件的中间部分，其改善密封，确保管状密封件的同心度，防止密封件被推动穿过推动开口，并且提供密封件和垫圈组件在服务室中的容易组装围绕推杆。维修室壳体的改进的端壁包括围绕安装螺栓的偏移凹陷的中心部分和通常围绕凹陷部分的较薄的优选V形接触表面。当安装螺栓上的螺母拧紧在安装支架上时，接触表面被紧紧地拉紧在安装支架上，显着减少了维修室端壁与安装支架之间的振动。

摘要： A punching device includes a C-frame on which a punch and stripping assembly is upwardly urged by a stripping spring, there being a horizontal retainer pin extending through one of two slots in such assembly and carried in a selected one of a plurality of holes in the frame for selecting the pinch point clearance, namely the clearance between the stripping sleeve and the die.

摘要： An improved mounting bolt for attaching brake actuators to the frame of a vehicle includes a head having outermost portions which contact the service chamber housing, and inner portions which are spaced from the housing. The bolt spreads the force from carrying the brake actuator over a greater area on the service chamber housing and away from the bolt hole. The bolt preferably has a generally rectangular head.
摘要翻译：用于将制动器致动器附接到车辆框架的改进的安装螺栓包括具有与操作室壳体接触的最外部分的头部和与壳体间隔开的内部部分。螺栓将来自承载制动器执行器的力传播到维修室外壳上的较大区域并远离螺栓孔。螺栓优选地具有大致矩形的头部。
