摘要:
In a pump housing (56) of a motor vehicle hydraulic unit which has at least one side surface (18), at least one main cylinder connection opening (44; 46), at least one pump element opening (28, 30) and a connecting line (58; 60) which connects the at least one main cylinder connection opening (44; 46) to the at least one pump element opening (28; 30) and is designed as a blind bore into the pump housing (56), the blind bore of the connecting line (58; 60) extends, according to the invention, from the at least one side surface (18) initially through the at least one pump element opening (28; 30) and subsequently into the at least one main cylinder connection opening (44; 46).
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.

The invention relates to a hydraulic braking system having a device for controlling brake slip, drive slip, and/or the driving stability of a vehicle. Among other things, such devices use pumps, valves, and reservoirs to control brake pressure in the wheel brakes in accordance with wheel slip occurring at the particular wheels. These components are in contact with each via a hydraulic circuit. The hydraulic circuit is built into a hydraulic block that has spaces for installing the components and channels for hydraulic contact. The invention makes possible a particularly compact and reduced-weight design of the hydraulic block and at the same time low manufacturing costs. For this purpose an advantageous layout and sealing of channels relative to each other and to the surrounding area is provided.

A device for damping pressure pulsations, in electronically regulatable vehicle brake systems for damping the pressure pulsations that are caused by pressure generators in a hydraulic circuit connected to it. The device has a housing which encloses a damping chamber and also has at least one hydraulic connection opening into the damping chamber, and a throttle device. The housing and throttle device are embodied as a compact damping unit that can be preassembled, is economical, and can be anchored in only a few work steps to the hydraulic block of an electronically regulatable vehicle brake system.

The invention relates to a housing block in an anti-lock hydraulic vehicle brake system, including a plurality of bores, conduits or holes intended for the function of the anti-lock arrangement. The invention provides that of these function-specific bores, conduits or holes, at least one bore (8), one conduit, or one hole is provided with an engagement face (14) for the positive engagement of a clamping means (16) of a machine tool. As a result, the production of separate clamping bores can be dispensed with.

A device for vibration-damping mounting of a vehicle brake system fluid assembly in a receiving opening includes a stay bolt, an elastic damping element in the form of a sleeve through which the stay bolt passes, a clamping sleeve guided by the stay bolt, and a screw element having an internal thread. The stay bolt comprises a connecting pin and a threaded shank having an external thread onto which the screw element can be screwed in order to move the clamping sleeve axially on the stay bolt towards the elastic damping element. The clamping sleeve and the screw element are in the form of a one-piece clamping element having a bearing shoulder, wherein the axial force generated by the clamping element as a result of the screwing-on movement acts via the bearing shoulder on the elastic damping element. A fluid assembly includes at least one such device for vibration-damping mounting.
摘要:
A piston pump for an electronically controllable vehicle brake system including a particularly simple, inexpensive, and space-saving throttle, and a filter hydraulically upstream of it, which prevents the throttle from becoming clogged with impurities. The pressure fluid outlet is routed at least partway along the circumferential surface of the bushing and, in the region of this section, the filter and throttle are embodied in one piece with the circumferential surface of the bushing.
摘要:
Pressure pulsations are damped in and a hydraulic unit by a device including a housing with an inlet and an outlet having a throttle and a filter preceding the throttle. The filter and the throttle are combined into a one-piece function element, which can be produced without metal-cutting machining and which can be fixed in the interior of the housing. This preceding filter prevents clogging of the throttle by contaminants in the pressure fluid, without requiring additional expense for parts or assembly. The function element can be produced economically in a minimum number of work steps, can be manipulated without problems, and in an advantageous refinement makes it possible to avoid unwanted accumulations of air in the device.
