Problems solved by technology

However, such a valve arrangement with pilot control requires a relatively large installation space in order to arrange all the components
[0006] In addition, undesired structure-borne sound effects and / or noises occur in the compressed air storage tank due to switching processes in the solenoid valve or the alternating magnetization energy

Embodiment Construction

[0057] figure 1 A schematic sectional view through the valve device 2 according to the invention is shown, which prepares and supplies compressed air according to the three-point function according to the electrical control signal that occurs.

[0058] The valve device 2 has a housing which is composed of a first housing part 4 and a second housing part 6 , wherein the housing parts 4 , 6 are sealed relative to each other by a sealing element 8 . A valve piston guide 10 extends in the first housing part 4 , on which a valve piston 12 is arranged movably along a valve piston axis 14 .

[0059] figure 1 shows the valve device 2 according to the invention in the exhaust position, in which compressed air is guided from the working chamber 16 via the bushing 18 axially fixed by the retaining ring 17 into the exhaust chamber 20 . The bushing 18 is here pneumatically sealed against the housing by means of a sealing ring 19 . On the side facing away from the retaining ring 17 , the...

Abstract

The invention relates to a valve device (2) for a compressed-air system, comprising a pressure-medium inlet (50) that can be connected to a pressure-medium source, at least one pressure-medium outlet (46) that can be connected to a consumer, and at least one vent (48) leading to the atmosphere. The valve device (2) also has a valve piston (12), which is movably arranged in a housing (4) and which moves an aeration piston (24) arranged separate from the valve piston (12) in order to open and close an inlet valve (38). The valve piston (12) is moved by means of an electromechanical linear drive (41), which linearly drives the valve piston (12) in accordance with an electrical control signal fed to the linear drive (41) in order to control pressures present at the pressure-medium outlet (46), e.g., brake pressures in a brake system. The invention further relates to a pressure control module for a compressed-air system of a motor vehicle having at least one valve device (2), and a motor vehicle, e.g., utility vehicle, having at least one valve device (2) and / or at least one pressure control module.

Description

technical field [0001] The invention relates to a valve arrangement for a compressed air system, a pressure regulation module having the valve arrangement and a motor vehicle having the pressure regulation module and / or having the valve arrangement. Background technique [0002] Compressed air systems in motor vehicles, in particular commercial vehicles, are used, for example, for systems such as the Electronic Brake System (EBS). In this case, the pressure of the compressed air system is influenced by means of an electronic regulator. For this purpose, when the brake pedal is actuated, the driver's braking desire is sent as an electrical signal to the control electronics, which communicates with the valve device, which adjusts the braking force in the brake cylinder according to the driver's braking desire. brake pressure. For example, in the case of an anti-lock braking system (ABS) or an anti-skid system (ASR), the valve unit must meet certain requirements regarding the...
