A hydraulic part of a magnet valve is received in a bore of a valve block. The hydraulic part is secured to the valve block with a calked heel of a securing bush that is slipped onto a guide sleeve of the hydraulic part. The securing bush rests on an annular shoulder of the guide sleeve and engages a jacket wall of the guide sleeve with a press fit, and one edge of the securing bush is adapted to a rounded-out throat between the jacket wall and an end wall of the annular shoulder by means of plastic deformation. A valve sleeve engages a portion of the bore of the valve block with a press fit. The calked heel, the plastically deformed edge of the securing bush, and the press fit of the valve bush seals that seal off against fluid are achieved without using additional rubber-elastic sealing means.

Magnet valve, in particular for a traction-controlled hydraulic vehicle brake system

A brake system for vehicles, in particular for motor vehicles, has electrically controlled hydraulic final control elements, integrated in a hydraulic block; a pressure sensor with a plurality of pressure measuring elements for measuring the hydraulic pressure controlled by the individual final control elements; and a control circuit for controlling the final control elements. For the sake of simple and secure mounting of the hydraulic block, pressure sensor and control circuit, the control circuit and pressure sensor are accommodated in a common housing of an add-on electronic control unit (ECU), from whose underside the pressure measuring elements protrude with smaller-diameter plug-in tubes. When the add-on ECU and hydraulic block are installed, and that the housing is mounted on the hydraulic block and solidly joined to it by insertion of the plug-in tubes into the fluid conduits, present in the hydraulic block, in a fluid-tight manner.

Electromagnetic valve housing containing throttle and check valve which

A structurally simplified 2/2-way shutoff valve having a parallel-connected pressure limiting valve. The shutoff valve has a first closing body that cooperates with a first valve seat. The first valve seat is embodied on a second closing body pierced by a conduit, which second closing body, under the influence of a spring, engages a second valve seat attached firmly to a wall which is secured to the housing. The biasing force of this spring is greater than a closing force exerted by an armature upon the first closing body and oriented in the opposite direction from the biasing force. The second closing body and the second valve seat form a pressure limiting valve, which is disposed in the housing of the shutoff valve. The invention is applicable to hydraulic motor vehicle brake systems having an anti-skid and traction control apparatus.

Electromagnetically-actuated 2/2-way valve, for hydraulic motor vehicle

A structurally simplified brake system which increases its functional reliability. The brake system has a brake pressure line extending between a master brake cylinder and a wheel brake. A shutoff valve is connected in parallel with a pressure limiting valve disposed in the brake line. A high-pressure pump toward the wheel brake side is capable of feeding pressure fluid into the line when the shutoff valve is closed. If a response pressure of the pressure limiting valve is exceeded, the pressure fluid can be diverted back to the master cylinder. The shutoff valve has a valve seat toward the wheel brake and a closing member toward the master cylinder which closing member is capable, by the action of a magnetic force on an armature of engaging the valve seat. A compression spring is disposed between the armature and the closing member and in the valve closing position exerts a closing force, adapted to the response pressure, upon the closing member. The shutoff valve and the pressure limiting valve are thus attained in a single valve unit.

Hydraulic brake system for motor vehicles

An apparatus for motor vehicles having traction control and/or anti-lock brakes. In a known apparatus, a distinction can be made between an unregulated and a regulated operating stage. In the regulated operating state, the position of a control device is determined by means of a control motor. In the unregulated operating state, a position of an operating element is transmitted to a control device with the aid of the transmission device. When the operating element is adjusted and the control device is restored by a restoring spring, however, a rotor of a control motor is adjusted along with them. This requires great actuation forces and a strong restoring spring. In this system, a third rotary element is provided. In the unregulated operating state, the third rotary element returns to a position of repose. In that case there is then no longer any operative connection between the transmission device and the control motor. The control device can thus be adjusted by the operating element with relative slight actuating forces. Nor is a relatively strong restoring spring necessary. Even if an electronic control system should fail, the control device can be adjusted without problems via the operating element. The apparatus is particularly suitable for motor vehicles having traction control and/or anti-lock brakes.

Apparatus having a control motor for intervention into a transmission

The invention relates to an apparatus for varying the position of a fuel control device that controls the output of an internal combustion engine and is connected to an operating element via a transmission device. In such an apparatus, a control motor can be operatively connected via a gear with a first rotary element connected to the control device and rotatably supported relative to a coaxial second rotary element connected to the operating element. The two rotary elements are prestressed by a spring that forces an arm each to contact one another at stops facing one another. To limit the control motor intervention to the regulated operating state, the invention provides a gear assembly that has at least one drive wheel operatively connected to the control motor, which drive wheel can be shifted from a position of repose, in which the operative connection with the first rotary element is interrupted, into a working position, in which the operative connection with the first rotary element is established to control the fuel control device.
