Description
本発明によれば、流体の運動を緩衝するための液跳ね抑制ポットを、特に還元剤を収容するタンクにおいてタンク底の凹所に半径方向および/または軸方向にガイド区分に沿ってガイドすることが提案される。このために、有利にはブロー成形法で製造されたタンクは、たとえばリブ状に形成することのできる幾つかの隆起部を備えている。ブロー成形法で製造されたタンクの特にタンク底に設けられた、リブ状に形成された隆起部は、タンク底の凹みにガイドされた液跳ね抑制ポットに向いたコンタクト面を有しており、特にタンク底における凹みの周に沿って配置された隆起部と、液跳ね抑制ポットの外側面における、隆起部に対応する凹所との間に、円錐角が形成されている。
図1には、特に還元剤を収容するのに用いられるタンクを示しており、タンクのタンク底には、ばねによって予荷重の掛けられた液跳ね抑制ポット(Schwapptopf)をガイドするためのガイド領域が形成されている。
