A pulsation damper for damping pressure medium vibrations in a hydraulic system, has a membrane within a bore of a housing, which membrane is exposed to the pressure medium on its one side and faces a gas-filled cavity inside the housing on its other side, the bore of which is closed by means of a plug. The membrane, in conjunction with the plug and a hollow-cylindrical support body, forms an independently handleable, functionally pre-testable assembly, for which purpose the membrane is substantially cup-shaped, and the support body extends into it.

A hydraulic unit for a slip-controlled braking system includes a housing body provided with a flange surface into which at least one additional bore joins. The bore, in addition to a cable through bore arranged in the housing body, is covered by an electromotor and/or a control device. The additional bore is either a leakage receiving bore or a noise reducing chamber.

Hydraulic unit

A hydraulic system for a slip-regulated dual circuit braking system includes two separating valve receiving holes disposed between a plurality of wheel brake connections which open up into the receiving body and the valve receiving holes of a first valve series include a plurality of inlet valves.

Hydraulic system

A hydraulic unit for slip-controlled braking systems has a plurality of receiving holes for transport devices associated with a plurality of hydraulic circuits bundled into groups, wherein the receiving holes are disposed at a distance from each in parallel with the upper side and a drive shaft having eccentrics located at the plane spacing for driving the transport devices. In order to provide a compromise optimized for manufacturing a small, convenient hydraulic unit, it is proposed that three theoretical planes (E, E, E) are arranged in parallel to the upper side, each receiving two V-shaped receiving holes for transport devices disposed at an angle to each other, and that the drive shaft includes three separate eccentrics for driving the transport devices.

A trailer device for driving stabilization of vehicle combinations is provided. In order to design a device for driving stabilization of passenger vehicle trailers in a cost-effective and simple manner, a brake system for braking the trailer by an overrun brake and for stability regulation is designed so as to have separating valves, switching valves, inlet and outlet valves and a pressure build-up pump. A stabilizing coupling is also connected by means of a second pressure medium pump to actuators which can vary the clamping force of the stabilizing coupling between the trailer and tractor vehicle if the second pressure medium pump conveys pressure medium from the storage tank into or out of the actuators.

An electrohydraulic unit assembly for a motor vehicle includes a receiving body defining a sealing face and at least two connectors fastened to the receiving body of the unit, oriented substantially parallel one to another and separated by a defined distance from one another. Each connector is configured for connecting a fluid conduit to the unit. Each connector includes a screw fitting for fastening the respective hydraulic connection to the receiving body of the unit such that a sealing face of the screw fitting or a sealing face of the fluid conduit is seated on the sealing face of the receiving body. Each screw fitting is rotatably connected to the body and includes two spanner flat portions having different spanner widths.

A conveying device for a vehicle brake system, to convey pressure fluids into at least one vehicle brake, or to convey pressure fluids into a pressure fluid accumulator, or to convey pressure fluids into a master brake cylinder with at least one moveable piston () in a receptacle () to displace pressure fluids from a working chamber ('), has at least one non-return valve (&#x2032;) to vent the working chamber () and to temporarily separate a hydraulic connection between the working chamber () and a hydraulic channel, whereby the non-return valve () must have at least one valve seat () and one valve body (). To achieve the simplest possible assembly of the non-return valve (), the valve seat () is assembled from several special valve seat segments ().

Conveying device

The invention relates to an electrohydraulic assembly for an electronically controlled brake system with an accommodating member which includes accommodating bores for electrohydraulic valves, accommodating bores for hydraulic supply devices and an accommodating bore for at least one roller bearing, and with hydraulic channels and pressure fluid ports, as well as with an electric motor comprising a rotor with a shaft that is mounted with the roller bearing in the associated accommodating bore in the accommodating member and used to drive the supply devices, and with an electronic control unit being connected to the electric motor by means of a plug penetrating a through-bore in the accommodating member. The objective is to provide a safe and comfortable operating characteristics even in consideration of extreme environmental influences. This object is achieved because the electrohydraulic assembly includes at least two brake circuits and at least two supply devices per brake circuit, and because the accommodating bores for the supply devices are arranged on top of each other along a first imaginary plane that extends in parallel to the shaft.

Electrohydraulic assembly for an electronically controlled brake system

The present invention related to a piston pump, in particular for controllable brake systems such as ABS or ESP, wherein a working chamber of the pump in front of a piston is delimited by a pressure valve, and a resetting spring with its one end is supported on a valve seat carrier of the pressure valve and with its other end resets said piston into its bottom dead center position. An object is to render the assembly of the mass-produced pumps as inexpensive and simple as possible. To achieve this object, the present invention discloses that the resetting spring be adapted to be attached directly or indirectly to the valve seat carrier in addition.

Piston pump

In a piston pump, in particular for pressure medium delivery in slip-controlled hydraulic brake systems, including a suction valve and a delivery valve, external preassembly and possibilities of external testing of the delivery and suction valves result from providing the suction valve and the delivery valve within a component which can be handled independently. The component preferably includes a delivery valve provided radially to the center line and a valve seat member, with a valve body of the delivery valve being prestressed by a tongue of a clamp, placed onto the valve seat member, against a valve seat formed within the valve seat member.

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.
