微型阀（10）具有形成在基部结构（12）中的流动开口，由在其正常状态下从流动开口升高的机械张紧的阀瓣（11）控制。 阀瓣的面向流动开口的侧面和阀瓣与基座结构之间的固定点具有绝缘涂层（17），用于将阀瓣与基座结构电绝缘，使得可以在 他们。

In a micro-valve (10) with a support structure (12), a passage opening (13) through the support structure (12), and a mechanically prestressed, at least one side mounted valve flap (11), which in its unactuated condition of the support structure (12) is bent and opens the passage opening (13) and rests in its actuated state to the support structure (12) and the passage opening (13) closes, an electrically insulating coating (17) is provided on the support structure (12) facing side of the is positioned valve flap (11) and the valve flap (11) mechanically biases. The coating (17) is in the fastening of the valve cap (11) area on the support structure in order to insulate the valve flap (11) electrically from the bearing structure (12).
