摘要:
A high-pressure pump having a housing containing at least one pump element that has a pump piston driven by a drive shaft; the piston is guided so that it can slide in a cylinder bore of a housing part and delimits a pumping chamber therein. A support element supports the pump piston against the drive shaft; and a prestressed return spring acts on both the pump piston and the support element in the direction toward the drive shaft. The support element is guided so that it can slide in a receptacle, which is contained in the housing part that also contains the cylinder bore, in the direction of the longitudinal axis of the pump piston, but cannot rotate around the longitudinal axis.

A high-pressure pump has at least one pump element including a pump piston defining a work chamber and driven at least indirectly by a drive shaft in a reciprocating motion, counter to the force of a restoring spring. The pump piston is braced on the drive shaft at least indirectly via a sleevelike tappet, and the restoring spring engages at least the pump piston. A support element in the tappet braces the pump piston toward the drive shaft and is braced at least indirectly on the drive shaft. The restoring spring, via a spring plate, engages the pump piston and the tappet. The spring plate is elastically deformable in the direction of motion of the pump piston in such a way that as a result of its elastic deformation, deviations in the position of its contact faces on the pump piston and on the tappet are compensated for.

A web unit for planet gear sets for the mounting of planet gears including a first web element and a second web element, which are tightly connected and can be tensioned in axial direction by transmission or connecting elements progressing in axial direction and describing a theoretical connecting axis. Each transmission or connecting element has regions of differing radial dimensions, the front faces of the regions, thus formed and facing the individual web elements, form a first and a second contact surface, resting either directly or through an intermediate element against the contact surfaces in contact regions, formed by the front faces of the web elements facing each other. At least one element forming a contact surface of a contact region includes a profile. The profile is characterized in the radially external region by at least one region of greater axial extension in the direction of the theoretical connecting axis.

In a method for influencing the roll behavior of a motor vehicle having at least one axle with wheels at opposite sides of the motor vehicle, vehicle body movements caused by transverse forces acting at the center of gravity are reduced in that for each vehicle axle wheel, a stabilizer with a hydraulic actuator generating a controllable force is provided and the stabilizer force is transmitted to the respective wheels and vehicle body for counteracting the vehicle body roll movements so as to improve the roll behavior of the vehicle with respect to accuracy and reaction speed.

In a suspension of a vehicle wheel on a vehicle body, including a spring element for accommodating the compressive forces acting between the vehicle wheel and vehicle body and with a linear actuator for adjusting the kinematics and the distance between the vehicle wheel and the vehicle body, the spring element and the linear actuator include at least one tubular contraction element with at least one hydraulic or pneumatic or hydropneumatic pressure chamber enclosed in a casing, which is designed in such a way that a pressure rise in the pressure chamber widens the casing radially and shortens it axially.

A casing for accommodating an operating pull for the purpose of attaching the operating pull to a bicycle gear, especially to a multiple-gear hub with a shifting wheel. The shifting wheel is placed, coaxially to the hub axis, at one of the ends of the hub. The shifting wheel is in contact with a control device that can be operated by the bicyclist during operation of the bicycle. The control device can include a remote-handling device that can be used by the bicyclist. The remote-handling device has a cable pull and a cable cover. The cable cover supports itself on the casing extension by an adjusting screw. The casing has a drive casing, for covering the shifting wheel, and a tubular casing extension, for accommodating the cable pull and an operating pull. The drive casing is connected to the casing extension by a joint with a cable guide. A spring storage and a coupling can be accommodated in the casing extension.

An intake filter for a hair dryer connectable to the housing of the hair dryer comprising a screen and a retaining element in the form of a cage structure adapted to fit in a ring. The retaining element forms at least one chamber, air-permeable in an axial direction, into which fragrant spheres can be inserted.

The present invention relates to a high-pressure pump, particularly for delivering fuel for a common rail fuel injection system, having a pump body in which at least one cam drive having a cam shaft is received. The cam shaft is pivotally supported about a cam shaft axis in the pump body and/or in a flange body by at least one bearing arrangement. The bearing arrangement includes a radial bearing bush extending in the direction of the cam shaft axis, and an axial bearing washer, which is integrally formed on the radial bearing bush. The axial bearing washer extends in a radial extension direction of less than 90 degrees relative to the cam shaft axis in the non-installed state. The radial extension direction is directed toward the radial bearing bush and can be brought into an axial bearing plane extending at an angle of 90 degrees to the cam shaft axis in the installed state by elastic deformation of the axial bearing washer.

A disk-packet unit comprising a pre-tensioned disk packet for mounting on guide elements in a transmission component. The packet comprises at least two adjacent elements that form frictional surfaces, which can be intercoupled in a frictional engagement by means of an intermediate element that forms a frictional surface and comprises an auxiliary mounting device. At least one spring device is located between at least two adjacent elements that form frictional surfaces. The auxiliary mounting device comprises a sleeve element and a tensioning device. The elements that form frictional surfaces are carried on the sleeve element and the latter comprises a stop. The tensioning device can be detachably connected to the sleeve element and produces a force for pre-tensioning the disk packet.
