The present invention relates to a method for pre-filling a low-pressure storage device (14) of a motor vehicle braking system (17), having a changeover valve (8), a hydraulic pump (9), an outlet valve (13), and a low-pressure storage device (14) situated in a suction line of the hydraulic pump (9). The low-pressure storage device (14) can be pre-filled in a particularly simple and low-noise manner if the actuation of the foot brake pedal (1) is monitored using a sensor mechanism and, when there is an actuation, the changeover valve (8) is closed in order to lock in the braking pressure acting on the wheel brake (11), and at least one of the outlet valves is opened in order to release the braking pressure into the low-pressure storage device (14).

The invention relates to a cylindrical filter element, which has a longitudinal slot in order to be able to expand the filter element elastically for the purpose of fitting in a circumferential groove. To prevent any fluid from being able to pass unfiltered through the longitudinal slot, the invention proposes to configure end faces, which delimit the longitudinal slot, such that they run in the secant direction or in the peripheral direction. This has the advantage that the end faces overlap and therefore the longitudinal slot is closed when the filter element is installed.

The invention relates to a hydraulic assembly of a vehicle brake system with traction control. Hydraulic assemblies include a housing block, which is to be fitted with hydraulic components, and an electronic control unit for activating the components. It is known for a hydraulic connection for a pressure sensor to be provided on a housing block and for the signal of the pressure sensor to be taken into consideration for brake pressure regulation in the control unit. The invention proposes an advantageous arrangement of at least one second hydraulic connection for a second pressure sensor on the housing block in combination with blind bores of the hydraulic connections. The blind bores can be positioned in a variable fashion and formed with different lengths during the production of the housing block. In this way, it is possible for the pressure in different hydraulic partial regions of a vehicle brake system to be sensed in an application-specific manner. The number of such hydraulic connections for pressure sensors has no influence on the external dimensions of the housing block.

A pump unit for a hydraulic vehicle brake system with traction control has an electric motor driving a radial piston pump. A rotor shaft of the pump unit has a hollow shaft with two standardized, hardened cylindrical pins that are press-fitted into the ends of the hollow shaft. The rotor shaft can be produced simply, economically, and without metal-cutting machining. The hollow shaft has high bending and torsional strength. The rotor shaft has a small diameter at the bearing points, which makes a small bearing diameter and thus a small installation space for the pump unit possible.

A multi-part filter combination is received in a stepped bore of a fluid-carrying component. A larger-diameter filter part is associated with a larger-diameter bore portion, and a smaller-diameter filter part is associated with a smaller-diameter bore portion. The two filter parts of the filter combination are connected by a connecting part. When the two filter parts are joined in their respective final position in the bore, this connecting part is detachable by means of a die to be introduced into the bore. The filter combination can be used in a valve block serving to receive a magnet valve.

摘要:
A pump housing for a hydraulic unit in a motor vehicle, includes a body that is provided with openings for accommodating components of an associated pump. One of the external surfaces of the body is designed such that a motor can be mounted thereon. A cutting process is not used to machine the external surface for mounting the motor.

A pressure fluid reservoir for a traction-controlled vehicle brake system; a reservoir unit including a plurality of pressure fluid reservoirs; and a method for producing a pressure fluid reservoir are disclosed. The pressure fluid reservoir with its structural size unchanged, has a larger installation space for a restoring element cooperating with a reservoir piston and at the same time can be produced economically. To that end, as the reservoir piston, a component reshaped in non-metal-cutting fashion from a sheet-metal material is proposed, on whose circumference an encompassing receptacle for a piston seal is integrally formed, likewise in non-metal-cutting fashion. The reservoir piston can be produced by deep drawing; the receptacle for the piston seal can be produced by roller-burnishing. Both method steps can be performed economically in one combined operation.
