A piston of a hydraulic power unit of a hydraulic power vehicle braking system including slip control is guided directly, without a cylinder liner, in a cylinder bore of a hydraulic block. The piston is rotatably fixedly and axially displaceably held in a bushing with the aid of an anti-rotation mechanism, which in turn is rotatably fixed at the hydraulic block. A pivot bearing of a worm gear for displacing the piston is fixed at the bushing.

A pedal travel simulator for a hydraulic powered vehicle braking system. In order to realize a 'jump-in,' a first piston spring is provided that, after a first displacement path, loads a simulator piston of the pedal travel simulator with a spring force that is higher by a multiple than that of a second piston spring that loads the simulator piston during the first displacement path.

Pedal travel simulator, and hydraulic block comprising a pedal travel simulator

A pedal travel simulator for a hydraulic power vehicle braking system. For the purpose of adapting to different main brake cylinders and of changing a spring characteristic curve, a stop is provided to be pressed into a piston of the pedal travel simulator. A pressing-in depth of the stop delimits a piston stroke.

Pedal travel simulator and hydraulic block including a pedal travel simulator

A hydraulic block includes pedal travel simulator for a hydraulic power-assisted vehicle braking system includes a piston that is displaceable in a cylinder, a piston spring that acts on the piston against the displacement, and a stroke limiter limiting the displacement. A characteristic curve of such a pedal travel simulator is set.

A hydraulic block is described for a braking system of a vehicle including at least one check valve, which is situated in a check valve receiving bore extending partially through the hydraulic block, including a valve seat and a valve body, the check valve receiving bore being formed as a stepped recess into the hydraulic block including a first subarea having at least one minimum diameter and an inner second subarea having at most one maximum diameter smaller than the minimum diameter; the valve seat is inserted onto and/or into the check valve receiving bore in a direct contact with at least one inner wall of the check valve receiving bore; and the valve body being inserted cageless and adjustable within the first subarea of the check valve receiving bore. A braking system for a vehicle and a manufacturing method for a hydraulic block for a braking system of a vehicle including at least one check valve are also described.

A hydraulic block of a slip regulation of a hydraulic vehicle power brake system that has a master brake cylinder bore and forms a master brake cylinder. In order to prevent a hard impact of a piston of the master brake cylinder against an end stop when the master brake cylinder is released, in particular when there is an abrupt release, for example when the foot slides off a foot brake pedal, a hydraulic return damper that is integrated in the piston is provided.

A pedal travel simulator for a hydraulic vehicle power braking system with a cup-shaped cylinder cover in which a piston spring is accommodated, which is held by an orifice disk as a stop for a piston of the pedal travel simulator in the cylinder cover. Recesses are provided in an outer edge of the orifice disk, through which the piston is able to displace brake fluid on its rear side out of a cylinder of the pedal travel simulator through a circumferential groove into a return.

A screw drive for an electromechanical brake booster of a braking system of a motor vehicle includes: a threaded nut; and a threaded spindle engaged with the threaded nut. The threaded nut includes an outer section which is connectable to a drive unit for driving the threaded nut, and an inner section having a thread for accommodating the threaded spindle. The inner section and the outer section of the threaded nut are connected by a damping unit for damping the torsion of the threaded nut.

An electromechanical brake booster for a brake system of a vehicle includes: a booster housing; and a valve element, which is situated in a continuous receiving opening of the booster housing in a manner that allows an adjustment in relation to the booster housing, and which has a continuous central opening within which a valve piston is positioned or able to be positioned in a manner that allows an adjustment in relation to the valve element such that a driver-applied brake force is transmittable via an input rod to an output rod. In addition, a ball segment is situated or developed on the valve element, which contacts a conical seat of a disk of the electromechanical brake booster situated between the ball segment and the booster housing so as to allow an adjustment in relation to the booster housing.

A magnet valve has a core sleeve in which a valve element is longitudinally movably arranged and has at least one housing sleeve overlaying the core sleeve which is connected to the core sleeve by welding from the outside. The weld is designed via a circumferential section or a plurality of circumferential sections of the housing sleeve forming at least one weld-free zone. A method for welding such a core sleeve of a magnet valve to the housing sleeve is also disclosed. The weld is made via a circumferential section or a plurality of circumferential sections of the housing sleeve, leaving at least one weld-free zone.

A valve module, in particular a solenoid valve for a brake system of a motor vehicle, is disclosed. The valve module includes an essentially cylindrical-shaped valve base body in which a valve needle is arranged in an axially displacable manner, and a housing cap which closes the valve base body on one end. The cap is maintained on the valve base body by at least one holding device. The maintaining device includes at least one recess on the outer surface of the cover of the valve base body into which plastically deformed material of the housing cap is introduced. A method for producing this type of valve module is also disclosed.

Disclosed is a solenoid valve having a magnet unit and a valve cartridge having a capsule, an armature guided longitudinally in the capsule and connected to a sealing pin guided longitudinally inside a valve insert, and a valve body with a sealing seat; a magnetic force generated by the magnet unit moves the armature together with the sealing pin from an initial position toward the valve body counter to the force of a return spring, causing the sealing pin to move into and close the sealing seat in an end position, where the initial position represents a maximum volumetric flow between a valve inlet and a valve outlet. A spring support is embodied and situated so that the return spring is supported outside the volumetric flow and presses the armature into the initial position against the capsule, and the inlet and outlet are embodied and situated so that the direction of the volumetric flow assists the closing motion of the armature with the sealing pin.
