Description
Die Erfindung betrifft ein Elektromagnetventil nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a solenoid valve according to the preamble of
Aus der
Die vorgestellte Ventilkonstruktion erlaubt keine Magnetkreisproportionalisierung. Das Ventil ist ausschließlich binär schaltbar und somit in seiner Funktion nur beschränkt einsetzbar.The presented valve construction does not allow magnetic circuit proportionalisation. The valve is only binary switchable and thus its function is limited.
Zur Vermeidung eines magnetischen Kurzschlusses ist der Magnetkern unterhalb der Magnetspule geöffnet, so dass bei einer ungenügenden Abdichtung des Ankerraums die Magnetspule dem Arbeitsdruck ausgesetzt ist.To avoid a magnetic short circuit of the magnetic core is opened below the solenoid, so that in an insufficient sealing of the armature space, the solenoid is exposed to the working pressure.
