The present invention discloses a hydraulic fluid accumulator comprising a housing having an interior subdivided into three chambers, with the first chamber being filled with a gas and separated from the second chamber by a first media separation element, the second chamber being filled with a fluid and separated by a second media separation element from the third chamber that is also filled with a fluid and connected to a hydraulic port. To safeguard an effective separation of media within the hydraulic fluid accumulator and, thus, a significant increase in its functional safety, the present invention arranges for the second media separation element to be embodied by a metal piston delimiting a chamber that can be vented in the housing.

Hydraulic fluid accumulator

The present invention discloses a pressure fluid accumulator with a housing having its interior subdivided into two chambers by a media-separating element, the first chamber being filled with a gas and the second chamber being filled with a liquid, and wherein in a hydraulic port a bottom valve is provided whose closure member is operable by the media-separating element and which permits filling the second chamber with liquid and prevents complete evacuation of the second chamber. In order to prevent a damage of the bottom valve and an inadvertent escape of fluid and, thus, ensure a considerable increase in the reliability in operation, according to the present invention, the closure member can be moved by the media-separating element to adopt a position in which it fulfils the function of a hydraulic piston.

Pressure means storage device

The present invention relates to a pressure sensor unit, in particular for a pressure control device, comprising a carrier housing for holding several pressure sensors, wherein the carrier housing accepts the pressure sensors as a modular assembly that can be preliminarily tested and forms an independent subassembly preferably arranged between a first and second housing of the pressure control device.

Electronically adjustable brake actuation system

Electronically controllable brake operating system

The present invention discloses a magnetic valve for liquid and gaseous working media, in particular for hydraulic brake systems in automotive vehicles, which includes a first cylindrical housing part that is encompassed on its outside by a magnetic coil and has a cylindrical recess inside which extends in an axial direction to accommodate and guide an axmature, a tappet which is displaceable by the armature in an axial direction in opposition to a resetting spring, a second cylindrical housing part which is arranged coaxially to the first housing part and includes a cylindrical recess extending in an axial direction, the said recess being in connection to outside valve ports and in which a valve seat cooperating with the tappet is arranged. According to the present invention, the first and second housing parts form a housing which is made in one piece of a ferromagnetic material and encompasses the armature over at least part of its longitudinal extension in the shape of a sleeve whose walls are sufficiently thick to reduce the magnetic short-circuit but are not thicker than required to reliably accommodate mechanical stresses.

Magnetic valve

The present invention relates to a pressure fluid accumulator which includes a housing with a pressure fluid port and a body which is movably arranged in the housing and isolates at least two chambers in the pressure fluid accumulator from one another. The body is configured as a metal pleated bellows which is movable in the housing and encloses the one chamber.
