Abstract
A switching assembly (10) having closure elements such as switch valves (18), for example, for closing intake lines (24b) and an intake manifold (28) in which the switching assembly is installed. The switching assembly (10) advantageously is composed of assembly injection-molded valve modules including switch valves (18) and a frame (14b). Alternatively, the switch valves (18) may also be injection molded directly in place in the support component (17). Because it may be pre-assembled, the entire switching assembly (10) may be easily installed in the intake manifold. In addition, the switching assembly preferably has rotational axes (15) which lie at a right angle to the alignment of the valves. It is advantageous that each switch valve (18) has its own rotational axis, thereby avoiding additive tolerances. In this way a part is provided which is economical to produce and which satisfies the sealing requirements for the switching assembly.
