摘要

The valve (8) has an opening and closing unit comprising a closing element (26) for closing a fluid passage (20), a first sealing joint (25) provided with a bearing surface (24), a back-pulling element (27) and a second sealing joint (28). The back-pulling element is arranged in a specific position of the closing element when the valve is not electrically activated. The second sealing joint is arranged to cooperate with the first sealing joint and the closing element to close the fluid passage. An electrical coil (21) is formed with an axial cylindrical recess (22). An independent claim is also included for an injection device.
