PCT No. PCT/DE98/02208 Sec. 371 Date May 1, 1999 Sec. 102(e) Date May 1, 1999 PCT Filed Aug. 1, 1998 PCT Pub. No. WO99/28142 PCT Pub. Date Jun. 10, 1999The invention is based on a magnet valve (10) for a fuel-regulated heating and/or cooling system, having a valve housing (16) that has an inlet conduit (18), an outlet conduit (20, 22), a return conduit (98), and a bypass conduit (24, 26) between the inlet conduit (18) and the return conduit (98), and having an electromagnetically switched valve member (32, 34) and bypass valve member (36, 38), which are secured together with an armature (86, 88) to a lifting rod (52, 54), and the valve member (32, 34) establishes the communication between the inlet conduit (18) and the outlet conduit (20, 22) and blocks it in a switching position in which it is supplied with current, while the bypass valve member (36, 38) controls the communication between the bypass conduit (24, 26) and the return conduit (98) as a function of the feed flow in the currentless switching position and establishes it in the switching position in which it is supplied with current. It is proposed that a plurality of valve units (12, 14) are provided, whose inlet conduits (18) communicate with one another.
