Abstract: The disclosure relates to a valve, in particular a solenoid valve, having an optimized seat geometry. The valve comprises a sealing element and a valve seat which surrounds a passage opening having a nominal diameter, the valve seat having on a side facing the sealing element a closed circumferential rounding which, in a cross-sectional plane which extends through a central axis of the passage opening, has a seat radius, a distance of a radius center of the seat radius from a wall inner side defining the passage opening being smaller than the seat radius.

Abstract: A valve armature of a solenoid valve includes an armature body having a blind hole in which an elastomer seal is vulcanized in. The armature body is manufactured in a cold forming process, in which a final axial linear dimension of the armature body is also determined. Furthermore, a valve having such a valve armature is presented.

Abstract: A solenoid valve has a housing which comprises a first and a second housing part, wherein a flexible diaphragm is arranged between the first and the second housing part. A movably mounted actuating element is provided which is connected to the diaphragm and detaches the diaphragm from a valve seat in an operating position of the first and the second housing part upon movement into an open position, and which presses the diaphragm onto the valve seat upon movement into a closed position. The first and the second housing part can take up a service position in which the diaphragm is accessible. The diaphragm is connected with a positive fit to the actuating element in a nondestructively detachable manner such that in the service position, the diaphragm can be removed from the actuating element by releasing the positive fit and can be connected thereto by establishing a positive fit. An assembly and a method of replacing a diaphragm are furthermore proposed.

Abstract: A magnet valve coil unit includes a magnet coil and a circuit board connected thereto, encased by a molding material. An LED on the circuit board signals a switching status of the magnet coil. The LED is surrounded by the molding material at least in part. A light guide element is arranged in contact with the LED such that it directs light radiated from the LED to an external surface of the magnet valve coil unit. The magnet valve coil unit is manufactured by applying a deformable, transparent mass on the LED of a pre-assembled component containing the magnet coil and the circuit board on which the LED is arranged, and placing the pre-assembled component in a tool mold. The light guide element is arranged to be in contact with the transparent mass, and the pre-assembled component is encased with a molding material.

Abstract: A fluidic control element has a housing that is assembled from first and second housing parts. A control space is formed between the housing parts into which two flow ducts open that are located in the first housing part. A sealing seat is arranged in the control space and is assigned to one of the flow ducts. A diaphragm is clamped between the housing parts. An actuating rocker element mounted for pivotal movement in the second housing part is configured with two lever arms, is movable between an opening position and a closing position, and is firmly attached to the diaphragm in an attachment area opposite the sealing seat. The actuating rocker element is provided with supporting areas for the diaphragm that are adjacent to the attachment area.
