Abstract
A miniaturized solenoid valve is provided which is suitable for integration in an electric or electronic control circuit by it being built up on a printed circuit board. The valve has a narrow elongated housing (10) with a fluidic space (26) at one longitudinal end, and a solenoid drive (12, 14) at the opposite longitudinal end. Soldering pins protrude from the base surface of the housing, which are electrically connected to the solenoid (12) of the solenoid drive. The fluidic connections are easily accessible from the top side of the housing (10).
Claims10
A miniaturized solenoid valve, comprising a generally parallelepiped housing (10) which contains a solenoid drive (12, 14) and a fluidic space (26) separated therefrom, said solenoid drive (12, 14) including a permanent magnet (20) which can move between two soft iron parts (22), and a solenoid (12) whose current-pulse induced magnetic field moves the permanent magnet (20) against one or the other soft iron parts (22), depending on the polarity of the magnetic field, said soft iron parts (22) being spaced from said solenoid (12) and supported by said housing (1O).
