摘要：
Disclosed is a valve drive unit (1). The valve drive unit includes a first SMA wire (10a) and a second SMA wire (10b), wherein the first SMA wire (10a) and the second SMA wire (10b) can be alternatively activated. The valve drive unit further includes a pivoting member (12), the pivoting member (12) being pivotable arranged around a pivoting member axis (A), the pivoting member (12) including a valve driver (13), the valve driver (13) being arranged at a distance from the pivoting member axis. The first (10a) and second (10b) SMA wire are coupled to the pivoting member (12) such that an activation of the first SMA wire (10a) causes the pivoting member (12) to pivot into a first direction and an activation of the second SMA wire (10b) causes the pivoting member (12) to pivot into a second direction, the second direction being opposite to the first direction. The valve driver (13) is designed to releasably engage a valve driver coupler (313) of a valve unit (31), such that, in the engaged state, a pivoting of the pivoting member (12) is transmitted to the valve driver coupler (313) via the valve driver (13).L'invention concerne une unité de commande de soupape (1). L'unité de commande de soupape comprend un premier fil SMA (10a) et un second fil SMA (10b), le premier fil SMA (10a) et le second fil SMA (10b) pouvant être activés de façon alternative. L'unité de commande de soupape comprend également un élément pivotant (12), l'élément pivotant (12) pouvant pivoter autour d'un axe d'élément pivotant (A), l'élément pivotant (12) comprenant une commande de soupape (13), la commande de soupape (13) étant disposée à une certaine distance de l'axe de l'élément pivotant. Les premier (10a) et second (10b) fils SMA sont couplés à l'élément pivotant de façon à ce qu'une activation du premier fil SMA (10a) amène l'élément pivotant (12) à pivoter dans une première direction et à ce qu'une activation du second fil SMA (10b) amène l'élément pivotant (12) à pivoter dans une seconde d
