Double solenoid valve

Abstract

Abstract The invention relates to a double solenoid valve having two valve seats (18 and 19) and two moving valve members (15 and 16), each of which can be operated by an armature (5 and 6) which is located in the magnetic field of in each case one coil (9 and 10), each magnetic circuit having ferromagnetic plates (1 and 2), provided on the coil end faces, and a magnetic circuit completion sleeve (3 or 4), surrounding the armature, which has an annular zone (13 or 14) of non- ferromagnetic material in its path, which annular zone is magnetically bridged by the raised armature (5 or 6) when the coil is excited. In order to create a simplified and compact layout, the two coils (9 and 10) have common ferromagnetic plates (1 and 2) and the two magnetic circuit completion sleeves (3 and 4) for the magnetic flux are connected in series, the two coils (9 and 10) preferably being arranged next to one another with mutually parallel axes, and their end faces lying in common planes and being switchable on and off in common.
