Abstract: In a solenoid valve for a hydraulic braking system, a mechanical locking device is formed between a guide assembly and a valve armature or tappet. The mechanical locking device releases the valve armature or the tappet in a currentless closed position such that the restoring spring drives the valve armature and presses the closing element into the valve seat to seal and fastens the valve armature or the tappet in a currentless open position against the force of the restoring spring in an axial locking position such that the closing element lifts from the valve seat. The valve armature includes a main-stage armature having a first surface to which pressure is applied and a preliminary-stage armature having a smaller, second surface to which pressure is applied. The preliminary-stage armature is mounted axially movably in the main-stage armature and interacts with a preliminary-stage seat by means of a preliminary-stage closing element.

Abstract: A normally closed solenoid valve includes a valve sleeve, a pole core fixedly positioned in the sleeve, an axially displaceable armature, a spring, a closing element, a valve seat, and an elastic component. The spring acts between the pole core and the armature in order to push the closing element into the valve seat. The closing element interacts with the armature. A prestressing force of the spring causes a deformation of the elastic component, which is positioned between the armature and the pole core, such that an impact of the armature on the pole core is damped via a regression of the deformation of the elastic component.

Abstract: An electromagnetically actuated valve, in particular a pressure control valve of a slip-controllable vehicle brake system, includes a seat body with a valve seat, at least one inflow channel, and an outflow channel. The valve includes a shut-off element configured to avoid a hydraulic short circuit between the inflow channel and the outflow channel when the valve seat is closed. The shut-off element is equipped with flow-directing means. The flow-directing means prevent the partial flows from the inflow bores from hitting each other and direct the flow to a closing body, which controls the valve seat, in such a way that a transverse force is applied to the closing body when the closing body performs a stroke motion. The transverse force radially deflects the closing body during an opening or closing motion and causes an effect that stabilizes the stroke motion and dampens radial vibrations.

Abstract: A solenoid valve for controlling a fluid includes an armature and a pole core. A working gap is provided between the armature and the pole core. The solenoid valve further includes a valve member, which is connected to the armature and can be moved together with the armature, and a valve body with a passage opening on which a valve seat is formed. The valve member opens and closes the passage opening on the valve seat. The solenoid valve also includes a restoring element which exerts a restoring force on the valve member to restore the valve member into a closed state. The armature has a central passage hole for receiving the valve member and the restoring element. The solenoid valve further includes a plunger stage which is formed between the pole core and the armature.

Abstract: A scanning sensor system for noncontact optical scanning of object surfaces having a sensor head (2) and an optics unit (3) as system components matched to one another. The optics unit (3) can be attached and positioned with high precision on the sensor head (2) by means of a fixing device (4). The fixing device (4) has three bearings (20, 21, 22), on which an optics unit (3) pressed against the sensor head (2) is borne and thereby positioned. Each of the three bearings (20, 21, 22) has a pair of bearing parts (17a, 17b; 18a, 18b; 19a, 19b) matched to one another in respect of their shape and positioning, these bearing parts having bearing surfaces in which respectively one of the bearing parts (17a, 18a, 19a) of the bearing part pairs is in contact with at least one bearing surface of the other bearing part (17b, 18b, 19b) of the bearing part pair.
