Patent

CA 2498361

Valves and methods for manufacturing the valves are disclosed. The valves are formed from a plurality of flexible polymer layers. A radio frequency bonding process, or the like, is utilized to form welds between the various layers. In general, a sub-assembly is formed that includes a valve layer bonded to a substrate layer. The sub-assembly is bonded to a second element such that a channel is formed between the valve layer and the second element. The channel includes an inlet, an outlet, and a pair of weld beads located in the inlet that place the inlet in an open configuration.

Soupapes et procédés de fabrication de celles-ci. Les soupapes sont constituées d'une pluralité de couches polymères flexibles. Un procédé de liaison par radiofréquences ou analogue est utilisé pour former les soudures entre les diverses couches. De manière générale, un sous-ensemble formé comprend une couche soupape liée à une couche substrat. Ce sous-ensemble est lié à un deuxième élément de manière à former un canal entre la couche soupape et le deuxième élément. Le canal comprend une entrée, une sortie et deux billes de soudure placées dans l'entrée de manière à former une configuration d'entrée ouverte.
