A method of diagnosing a valve is described, which has an electrodynamic actuator, which includes a magnet arrangement for generating a magnetic field and a control element which is movable relative to the magnet arrangement and is coupled to a movably arranged coil. At least one electrical variable of the electrodynamic actuator is measured over a measurement period to detect a time course of the electrical variable. The time course of the electrical variable is evaluated over an evaluation period to determine at least one induction-dependent valve variable which is assigned to the motion profile of the electrodynamic actuator. A diagnosis module and a valve are furthermore described.

Method of diagnosing a valve, diagnosis module, and valve

A valve having a valve body to which an actuator can be fastened is specified, the valve body including at least a first and a second housing part made of plastic, a first fluid duct being formed in the first housing part and a second fluid duct being formed in the second housing part, and at least one of the two fluid ducts opening out at a valve seat, and at least one elongated, rectilinear stiffening element being inserted in sections both into the first housing part and into the second housing part, and the at least one stiffening element being at least approximately perpendicular to a plane in which the at least one valve seat extends.

Valve having a valve body

A valve with an electrodynamic actuator includes a magnet device that generates a magnetic field and a drive element that is movable relative to the magnet device. The drive element is pivotally mounted and comprises a current-carrying air coil that is arranged in the magnetic field and is fixedly coupled to a coil carrier made of a non-magnetic material. Sealing surfaces for sealing valve seats are arranged on two opposite sides of the drive element, such that the sealing surfaces face in opposite directions. A housing is comprised of a plurality of plastic housing parts and a metallic encasement. The metallic encasement surrounds an upper area of the housing in which the electrodynamic actuator is arranged and at least partially surrounds a lower area of the housing in which fluid channels are arranged.

Valve with electrodynamic actuator

An electrodynamic actuator, in particular for a microvalve or a micropump, includes a magnet arrangement for generating a magnetic field and a control element movable relative to the magnet arrangement. The control element includes an energizable air-core coil () which is arranged in the magnetic field and firmly coupled to a coil carrier () made from a nonmagnetic material.

A method of manufacturing valves which are driven in particular in magnetic manner. At least one pressing piece is fastened to a rocker for moving a sealing element, in fact in a position of adjustment for adjusting a fixed valve stroke. Further, a valve and a valve bank are suggested.
