Definitions

• the invention is based on a valve for controlling a fluid, in particular for controlling a gas, according to the type defined in more detail in the preamble of claim 1.
• Such a valve is known from practice and can be used, for example, as a gas control valve in a fuel cell or also in a gas engine.
• the known valve comprises a valve housing, which receives a particularly electromagnetic actuation unit for a magnet armature and is provided with a housing sleeve in which the magnet armature is guided so as to be axially displaceable.

• valve according to the invention for controlling a fluid, in particular for controlling a gas, with the features according to the preamble of claim 1, in which valve the magnet armature is guided on an armature sleeve which is arranged in the housing sleeve, has the advantage that the armature sleeve can be produced in a simple and inexpensive manner with a uniform inner diameter and thus with good concentricity properties, which have an advantageous effect on the endurance properties of the valve.
• the anchor sleeve there is therefore an additional guide sleeve, which optimizes the guide conditions and thus a low tendency of the magnet armature to tilt and consequently ensures a low wear in the area of the guide of the magnet armature and also in the area of the valve seat.
• the uniform inner diameter of the armature sleeve enables the magnet armature to be machined to produce an outer diameter corresponding to the armature sleeve according to a simple series process, such as, for example, a through-grinding process, since only one guide diameter is required on the magnet armature.
• the anchor sleeve can be integrated in a simple manner, so that it can be integrated into the housing sleeve with little effort even with existing series production processes.
• the valve according to the invention is particularly suitable for mass flow control of gases such as hydrogen and natural gas and can be used for example in a fuel cell or also in a gas engine.
• the anchor sleeve is connected to the seat plate via a press connection.
• a seat plate can be used which essentially corresponds to a previously used seat plate and can be modified with little effort to connect the anchor sleeve.
• it can be welded to the seat plate.
• the anchor sleeve is connected to the seat plate by an adhesive connection or by a flange.
• the anchor sleeve is made in one piece with the seat plate and is in particular designed as a deep-drawn part.
• the anchor sleeve and optionally the seat plate can also be designed as a turned part, as a MIM (metal injection molding) part, as an extruded part or the like.
• a leak test of the valve according to the invention can already be carried out directly on a functional group consisting of the armature sleeve, the seat plate and the magnet armature.
• a leak test can only be carried out if the assembly consisting of the magnet armature and the seat plate is installed in the housing sleeve or the valve housing.
• the magnet armature can be guided in the armature sleeve via at least one guide collar, preferably via two guide collars of the magnet armature.
• the magnet armature can also have a guide area which extends over a wide area in the axial direction of the magnet armature and essentially lies with its entire circumference on the inner wall of the armature sleeve.
• the magnet armature can be designed such that a region of increased diameter is arranged outside the armature sleeve. In this case, the area of increased diameter may border the housing sleeve, which is enclosed by the magnetic actuation unit, via an annular gap. It is also conceivable that the area of increased diameter of the magnet armature is guided on the housing sleeve.
