包括改进的用于连接至低压源的连接元件的真空制动助力器
摘要：
本发明涉及包括改进的用于连接至低压源的连接元件的真空制动助力器，该真空制动助力器(10)包括壳体(12)和用于将该真空制动助力器连接至低压源的角形的连接元件(16)，所述连接元件(16)包括：第一连接件(22)，其延伸穿过所述助力器的壳体(12)中的开口(28)而进入真空制动助力器的低压腔室(14)；第二连接件(26)，其用于将所述连接元件(16)连接至低压源；和多部件壳体(18)，其包括承载所述第一连接件(22)的第一壳体部件(20)和承载相对于所述第一连接件(22)以第一角度(α)布置的所述第二连接件(26)的第二壳体部件(24)。为简化自动组装，第二壳体部件(24)相对于第一壳体部件(20)的位置成第二角度(β)刚性地固定，且制动助力器的壳体(12)中的开口(28)的形状和第一连接件(22)的截面形状以这样的方式协调，即，至少基本防止第一连接件(22)在制动助力器的壳体(12)的开口(28)中旋转。
摘要（英）：

The invention relates to a vacuum brake booster (10) comprising a housing (12) and an angular connection element (16) for connecting the vacuum brake booster to a low-pressure source, said connection element (16) comprising a first connecting piece (22) which extends through an opening (28) in the booster housing (12) into a low-pressure chamber (14) of the vacuum brake booster, a second connecting piece (26) for connecting the connection element (16) to the low-pressure source, and a multi-component housing (18) comprising a first housing part (20) carrying the first connecting piece (22), and a second housing part (24) carrying the second connecting piece (26) which is arranged at a first angle (a) to the first connecting piece (22). In order to simplify an automatic assembly, the position of the second housing part (24) in relation to the first housing part (20) is rigidly fixed in relation to a second angle (ss), and the form of the opening (28) in the brake booster housing (12) and the cross-sectional form of the first connecting piece (22) are co-ordinated in such a way that a rotation of the first connecting piece (22) in the opening (28) of the brake booster housing (12) is at least essentially prevented.
