摘要： A power booster includes a housing with a rear housing section and a front housing section defining an internal cavity. A housing wall separates the internal cavity into a first chamber and a second chamber with an opening formed in the housing wall, wherein it is desirable to extend a component through the opening. A tube has an end secured in the opening in the housing wall. The tube's end includes a radially directed wall extending from the end of the tube that extends to an axially extending wall positioned concentrically with the tube and terminating with an outwardly turned segment. The axially extending wall is positioned within the opening in the housing wall with a seal positioned between the axially extending wall and the housing wall wherein the distance between the front housing section and the rear housing section is minimized, by extending the component through the tube.

摘要： A connecting member and method of attaching the connecting member and a tube member to a housing of a vacuum brake booster is provided. The connecting member includes a cylindrical body portion having a first end and a second end. A rim portion is formed between the first end and the second end, and a stem portion is formed at the second end of the cylindrical body portion. The stem portion includes a tapered end portion to allow the stem portion to flow radially outward when a force is applied to the stem portion. The cylindrical body portion further includes a first opening formed in the cylindrical body portion adjacent to the first end of the cylindrical body portion and a second opening in communication with the first opening. The first opening has a first diameter and the second opening has a second diameter. The second diameter is less than the first diameter. The stem portion is deformed to create a seal between a portion of a housing member and the connecting member. A tube member includes a first end portion that is received in the first opening of the cylindrical body portion.
摘要翻译：提供了一种连接构件和将连接构件和管构件附接到真空制动助力器的壳体的方法。连接构件包括具有第一端和第二端的圆柱形主体部分。边缘部分形成在第一端和第二端之间，并且杆部形成在圆柱形主体部分的第二端。杆部分包括锥形端部，以当力施加到杆部分时允许杆部分径向向外流动。圆柱体部分还包括形成在圆柱形本体部分中的与圆柱体部分的第一端相邻的第一开口和与第一开口连通的第二开口。第一开口具有第一直径，第二开口具有第二直径。第二直径小于第一直径。杆部分变形以在壳体构件的一部分和连接构件之间产生密封。管构件包括容纳在圆筒体部的第一开口中的第一端部。
