摘要:
A valve having a magnetic armature, which is moved longitudinally in a valve dome; a valve tappet of this armature carries a closing member of a seat valve, which is open when in the rest position. The seat valve is disposed in a valve chamber, from which two pressure fluid conduits lead to face ends of the magnetic armature, which is sealed on its circumference side. When the seat valve is partially open, a pressure is produced in a partial valve chamber by means of a shaping of the valve seat as a hollow cone and of the closing member as a flattened end ball. In the control chamber remote from the closing member, this pressure leads to a movement of the magnetic armature against the tension of a restoring spring, which results in a reduction of the through flow cross section of the seat valve. The valve is particularly useful in slip-controlled hydraulic brake systems of motor vehicles.
摘要:
An electromagnetically actuated valve which achieves the setting of a reduced cross section of flow following a closed position of the valve. The solenoid valve has a seat valve which is surrounded by a sleeve which is secured pressure-tightly on a valve body. In the closed position of the seat valve, a tappet engages in the sleeve, forming a small radial gap. From the interior of the sleeve, a first pressure-medium passage leads to an end face of a magnet armature, said end face being remote from the seat valve. Outside the sleeve, a second pressure-medium passage leads to that end face of the magnet armature which is close to the seat valve. In the case of a pressure drop between the pressure-medium inlet and the pressure-medium outlet of the solenoid valve, the seat valve can assume a partially open position following a closed position of said valve since, due to the gap, which acts as a restriction, a pressure disequilibrium arises at the magnet armature and valve opening forces are compensated. The valve can be employed in slip-controlled hydraulic brake systems of motor vehicles.

[The aim is to] A solenoid valve which achieves a setting of a reduced flow area which is active after a closed position of the valve is disclosed. The solenoid valve has a seat valve in a valve chamber. A magnet armature for actuating the seat valve is provided on its end face remote from the seat valve with an axially expandable hollow part whose interior, acting as a control chamber, is connected to a valve sub chamber through a pressure fluid channel. A [D]dynamic pressure is generated in the partly open position of the seat valve in the valve subchamber and is capable through expansion of the hollow part in the control chamber of causing a force which acts on the magnet armature against the force of a resetting spring and on the basis of which the seat valve maintains its partly open position. The valve can be used in slip-controlled hydraulic brake systems of motor vehicles.

An arrangement of two elements to be connected to each another of thermoplastic material is proposed. For instance, an annular coil (7) is disposed in a tight housing; the housing (8) and the coil body (1) comprise the thermoplastic material with different melting points, and the two intermesh with one another via grooves. The housing (8) sheathes a coil end plate (3), in the form of an extension, almost completely on at least one side, that is, the side on which the coil end plate is disposed. On the other face end (4) and on the outer circumference of the coil end plate (3), the coil end plate (3) has annular grooves (5, 6), into which the thermoplastic material of the housing (8) can be introduced during the sheathing in a hardening manner.

In a connection arrangement between a sensor and connection leads, only a small installation space is required. To this end, the connection arrangement has a signal amplifier, which is electrically contacted by means of bond connections with the sensor and the connection leads. This is achieved by means of connecting elements, which are designed as thin sheet-metal shaped parts and are fixed with tab-shaped end sections in a housing of plastic, in which the signal amplifier is also inserted. The end sections, the signal amplifier, and the bond connections are arranged in a space-saving manner in roughly one plane. The connection arrangement is especially suited for sensors used to measure the speed of motor vehicles.

A vehicle hydraulic brake system having brake pressure modulation valve assemblies, between a dual-circuit master cylinder and wheel brakes of vehicle wheels. The pump device is embodied as a low-pressure pump with the brake pressure modulation valve assemblies be assigned a first and second return pump and that in the automatic braking mode the first pressure chamber is made to communicate with a first return pump and the second pressure chamber is made to communicate with the second return pump, on the inlet side in both cases. The low-pressure pump, in the automatic braking mode, generates charge pressure for the return pumps that is substantially below a maximum brake pressure, and the return pumps generate the maximum projected brake pressure and serve, in the additionally possible anti-lock mode, to return pressure fluid from the wheel brakes to the master cylinder. The vehicle brake system is an inexpensive low-pressure pump that offers a high possible capacity of the return pumps in the automatic braking mode.
