An aircraft seat module includes an enclosure unit which delimits a flight passenger seating region at least partially, and includes a door unit which at least closes a passage region to the flight passenger seating region in one or more operation states. The aircraft seat module further includes a bearing device which supports the door unit movably relative to the enclosure unit and has for this purpose a bearing module having a first bearing element and a second bearing element which are supported such that they are movable relative to each other.

A piston pump assembly for a hydraulic power vehicle braking system including an electric motor, a planetary gear set, a helical gear, and a piston which is displaceable in a cylinder. To prevent the piston from rotating in the cylinder, cylinder pins are situated in grooves at an inner side of the cylinder and engage with the recesses in a flange of the piston. Due to reshaping, the grooves are closed at one end, so that the cylinder pins are axially secured.

A brake booster for a brake master cylinder of a motor vehicle, including a drive motor, which is connected/is connectable via a transmission to a pressure piston for the brake master cylinder, the transmission including a rotatable spindle nut having an inner thread, and a rotatably fixed axially displaceable spindle rod having an outer thread, the threads engaging with one another in order to convert a rotational movement of the drive motor into a translational movement of the spindle rod, and the spindle nut including an outer toothing, which is engaged with a toothing of a drive wheel of the transmission. It is provided that the spindle nut is displaceable axially relative to the drive wheel.

Brake booster and brake device including a brake booster of this type

A brake booster for a brake master cylinder of a motor vehicle includes a drive motor that is connected/connectable by a gear unit to a pressure piston for the brake master cylinder, the gear unit converting a rotational motion of the drive motor into a translational motion of the pressure piston to actuate the brake master cylinder, and the gear unit including a rotatable spindle nut and a non-rotatable spindle rod having intermeshing trapezoidal threads that have have a flank clearance and a tip clearance that are greater than a bottom clearance.

Brake booster and brake system

A brake booster for a main brake cylinder of a motor vehicle includes a drive motor connected or connectable to a pressure piston for the main brake cylinder via a gear unit, where the gear unit includes a rotatable spindle nut, including a female thread and an axially displaceable, but rotatably fixed, spindle rod that includes a male thread, the male and female threads engaging into each other in order to convert a rotary motion of the drive motor into a translational motion of the spindle rod for actuating the pressure piston. The spindle nut is formed as two pieces and includes an inner part including the female thread and an outer part including an outer toothing, the inner and outer parts being made of different materials.

Brake booster for a motor vehicle

A brake booster for a brake master cylinder including a drive motor connected via a linkage to a pressure piston for the brake master cylinder, the linkage having a rotatable spindle nut having an internal thread and a nonrotatable, axially displaceable spindle rod having an external thread, the threads interengaging to convert a rotational motion of the drive motor into a translational motion of the spindle rod in order to displace the pressure piston. The spindle nut has an external tooth set that is in engagement with an internal tooth set of a annular drive gear of the linkage. The spindle nut is axially displaceable with respect to the annular drive gear. Except for a first tooth flank of a tooth, which extends in a first axial portion in its longitudinal extent toward an oppositely located tooth flank, tooth flanks of the internal and external tooth sets extend axially.

A rotation/translation converter gear unit having a helical gear and a planetary gear for driving the helical gear. A spindle nut of the helical gear forms a planet carrier for planet wheels of the planetary gear. Situated between the planetary gear and the helical gear is an axial friction bearing, that at the same time forms a centering element which centers a sun wheel of the planetary gear between the planet wheels. In particular, the rotation/translation converter gear unit is used to drive a piston of a pressure generator for a brake control of a hydraulic vehicle brake system.

The invention relates to a fuel injection valve, comprising a nozzle body () and a pressure chamber () formed therein, wherein the pressure chamber () can be filled with fuel under high pressure and wherein a piston-shaped nozzle needle () is arranged in the pressure chamber so as to be movable longitudinally, which nozzle needle interacts with a nozzle seat () formed in the nozzle body () by means of a sealing surface () formed at the end of the nozzle needle on the combustion chamber side and thereby controls the flow of fuel from the pressure chamber () to at least one injection opening (). A sleeve () accommodates the end of the nozzle needle () facing away from the nozzle seat and bounds a control chamber (). By means of the pressure of the control chamber, a hydraulic force is applied to the nozzle needle () in the direction of the nozzle seat (). A closing spring () is arranged in the control chamber (). The closing spring is arranged between the sleeve () and the nozzle needle () under compressive preload.
