Beschreibung
Zusammenfassung:	A rotary valve spindle for flow control in the head of a filter includes a unitary dual function seal that is carried by the spindle and seals against the inner surface of the filter head during spindle rotation between flow and no- flow positions. The dual function seal greatly simplifies manufacture and assembly of the valve. L'invention concerne une tige de soupape rotative de réglage de débit positionnée dans la tête d'un filtre, comprenant un joint unitaire à double fonction porté par la tige et appliqué contre la surface interne de la tête de filtrage au cours de la rotation de la tige entre des positions d'écoulement et de non-écoulement. Le joint à double fonction simplifie de manière significative la fabrication et l'assemblage de la soupape.
