Abstract: An electromagnet including a wire coil and a coil core, wherein the wire coil is accommodated on a coil body and includes a plurality of windings which surround the coil core and define a winding axis, wherein the coil body includes end pieces spaced apart along the winding axis and axially bounding the wire coil, which end pieces are connected to each other by at least two connecting webs extending along the winding axis and defining, together with a recess in at least one of the end pieces, an accommodating space for the coil core which is bounded by a rectangular envelope having at least one profile protruding inwards in a cross-sectional plane oriented perpendicular to the winding axis, and wherein the coil core has a recess which extends along the winding axis in at least some sections and which corresponds to the profile.

Abstract: A diaphragm valve has a valve housing and a valve member movable relative to said housing. The valve member includes a diaphragm carrier that can be driven to execute a switchover motion having a sealing diaphragm mounted thereon, which delimits a valve chamber in which a valve seat is found. The sealing diaphragm has a sealing section opposite said valve seat belonging at least partially to a loose diaphragm section of the sealing diaphragm, which can lift from the diaphragm carrier to reduce the stress on the sealing diaphragm when said diaphragm carrier is removed from the valve seat during switching.
