Definitions
- the invention relates to a pneumatic or hydraulic switching arrangement.
- Electronically controlled systems for compressed air preparation generally convert the control commands from the control electronics via solenoid valves. Such systems are known for example from DE 10 2006 034 762 B3.
- the valve may overheat. If the inner resistance is too great, the current is too low, so that no sufficient switching force can be exercised. Especially in vehicles, the
- a solenoid valve is mounted close to the controlling control unit, it can be controlled in terms of percentage clocked, so that the effective
- Voltage supply can be adjusted independently of the supply voltage. However, then the supply line from the controller to the device valve as an antenna that emits a high level of electromagnetic interference. Therefore, one is clocked control of solenoid valves often not possible. Solenoid valves that have both a large torque and are designed for continuous operation are expensive. Task and solution
- This arrangement comprises at least one device which is switchable by pressurizing a pneumatic or hydraulic control input from a first operating state to a second operating state.
- control input is preceded by a control volume for a pressure medium.
- This control volume is connectable by a first solenoid valve and / or by a series connection of this first solenoid valve with a second solenoid valve with a source of pressure medium. Furthermore, it has at least one by a second solenoid valve and / or by the
- Pressure medium wherein optionally also one and the same outlet both by a second solenoid valve controlled, as well as can be throttled.
- the control volume is otherwise completed.
- the first solenoid valve and / or its series connection with the second solenoid valve can be converted into an impermeable for the pressure in the control volume switching position.
- the first solenoid valve is a 2/2-way valve and only responsible for the connection of the control volume with the source of the pressure medium.
- the second solenoid valve is then also a 2/2-way valve and only for the control of the outlet of the
- the solenoid valves are designed as monostable valves. Then they are automatically returned to a defined position in case of failure of the electrical supply. Starting from this defined position, for example, pneumatic back-up circuits can be planned.
- Solenoid valves must be subjected to power only for much shorter times than in the prior art:
- the control volume has been filled by the first solenoid valve and / or by the series connection with the pressure medium and it has only outlets, which are controlled by solenoid valves may be through the first solenoid valve and / or through the
- Compressed air treatment plants the duty cycle of the solenoid valves not determinable in advance. For example, it depended on the ones to be followed
- ABS Antiblockiersy stars
- Scarf tanix is not installed in a compressed air treatment plant. On the one hand, compressed air is available everywhere and, on the other hand, does not have to be returned to a reservoir after use.
- control volume has a throttled outlet for the pressure medium, which is not blocked by a further solenoid valve, the device by single activation of the first solenoid valve and / or by the
- Solenoid valve with the second solenoid valve and the control volume arranged in the direction of the control volume pressure relief valve. Then, the first solenoid valve and / or the series connection can be relieved of pressure without the set switching state is lost.
- Solenoid valve and / or its series connection with the second
- Solenoid valve connected in the regeneration path of a compressed air supply system.
- the solenoid valve or the series connection can then be in the open state, a return flow of compressed air, which from the through the System supplied by at least one facility to
- This device may in particular be an air dryer.
- the regeneration path can, for example, bridge a check valve, which otherwise allows air flow only from the air dryer into the supplied area and not vice versa.
- the switchable device comprises a in the compressed air supply system promoting compressor and / or a vent valve for the volume in which promotes the compressor. In this way it can be avoided that the
- Compressed air treatment is hindered by a built-up by the compressor backpressure. After the first solenoid valve, or his
- the control air is included in the control volume before the control inputs of the compressor and / or the vent valve.
- the compressor can therefore be prevented for as long as possible to promote compressed air in the compressed air supply system, without the constant need for a solenoid valve must be active. Conversely, no permanent activation of a solenoid valve is necessary when at high
- Compressed air consumption constantly compressed air must be conveyed into the system.
- a solenoid valve must be active only briefly, if the promotion of compressed air to be switched on or off or if a regeneration of the device for
- the compressed air supply system is advantageously designed so that the compressor promotes compressed air into the system during a maximum of 50% of the total operating time and the device for compressed air treatment during a maximum of 10% of
- control volume has a leak
- delivery of the compressed air is switched on again as soon as the pressure in the control volume has fallen below a certain level.
- means for refilling pressure medium in the are advantageous
- Control volume for securing a pressure enclosed in the control volume provided.
- These means may be, for example, in a control of the first solenoid valve or its series connection with the second solenoid valve, which in the pressurized state of the control volume of this first
- This embodiment is particularly advantageous when the switching arrangement is used to control an electropneumatic parking brake.
- a parking brake is usually designed as a spring-loaded brake, i. It is applied by a spring force and released by applying the spring brake cylinder with a release pressure.
- a fluid-actuated valve which has an outlet for the
- Pressure fluid from the control volume opens when the pressure at at least one other location in the scarf tanix a predetermined value or
- the switchable device is switched back from the second operating state to the first operating state.
- the switching arrangement is installed, for example, in a compressed air supply system and controls the control volume of the compressor and / or a venting valve for the volume in which the compressor, the shading is preferably selected so that the compressor at normal pressure control volume normal air in the
- Compressed air supply system promotes. If the control volume through the first solenoid valve, or by its series connection with the second
- Solenoid valve filled with compressed air, the promotion of compressed air is suppressed. So that important compressed air consumers, such as the brake system, even in case of failure of the electrical supply continue to receive compressed air, monitors the control input of the pressure-medium valve advantageously a location in the supplied area of the compressed air supply system. For this purpose, for example, the prevailing at this location pressure can be applied via the control input against the action of the valve spring. There is sufficient supply in the supplied area
- the pressure-actuable valve is thereby held in the closed position, and the control air remains trapped in the control volume. If the pressure in the supplied area drops, the spring force predominates and switches this
- the closing pressure of the pressure-medium valve is lower than the pressure, from which the delivery of the compressor is reactivated when the electrical supply is functioning.
- Control volume is then a pure back-up for failures of the electrical
- the vent valve has a second control input which, when pressurized above a predetermined value, opens the vent valve and which is connected to the volume into which the compressor delivers or to the area supplied by the compressed air supply system. Then it fulfills a dual function and not only allows the interruption of the
- Compressed air delivery by driving the first solenoid valve or the
- Solenoid valve designed such that
- the first solenoid valve and the second solenoid valve each provide at least the functionality of a 3/2-way valve
- the second solenoid valve connects its output connected to the input of the first solenoid valve in a first switching position with a vent and in a second switching position with the source of the pressure medium;
- the first solenoid valve has at least two outputs, which are connected to two independent control volumes for the control of different control inputs, wherein the first solenoid valve in each switching position connects at least one control volume to the input and shuts off at least a second control volume.
- the second solenoid valve in its first switching position, one of the control volumes is vented. Which control volume is vented is selected by switching the first solenoid valve. On the other hand, if the second solenoid valve is in its second switching position, one of the control volumes is pressurized by the pressure medium source.
- Control volume is pressurized, by switching the first
- Solenoid valve selected.
- This control volume can for example control a vent valve, so that whenever the regeneration path is opened, the air flowing back through the air dryer and moisture laden air can flow through this vent valve to the outside.
- the output of the second solenoid valve with that control volume which is shut off in the de-energized state of the first solenoid valve of this first solenoid valve, connected via a first solenoid valve bypassing in the opening in the direction of this control pressure relief valve is arranged.
- this control volume regardless of whether the first solenoid valve is energized, be filled by energizing the second solenoid valve with pressure medium. If both solenoid valves are energized, both control volumes can be filled simultaneously with pressure medium. If a pressure-medium-actuated valve is provided which opens an outlet for the pressure medium from the control volume connected twice (via the first solenoid valve and via the first solenoid valve bridging pressure relief valve) depending on the pressure at at least one other location in the switching arrangement, this outlet is at a Failure of the electrical supply also act simultaneously on the second control volume, since the first solenoid valve in his first switching position falls back and thus releases a path from the second control volume to the connection between the two solenoid valves.
- Solenoid valve designed such that
- the first solenoid valve and the second solenoid valve each provide at least the functionality of a 3/2-way valve
- the second solenoid valve connects its output connected to the input of the first solenoid valve in a first switching position with a vent and in a second switching position with the source of the pressure medium;
- the first solenoid valve in the energized state its input with at least one control volume connects and in the de-energized state part of a regeneration path for the regeneration of a compressed air treatment device of a

- FIG. 1 compressed air supply system with an embodiment of
- FIG. 2 realization of a pneumatic back-up for the one shown in FIG.
- Figure 1 shows a compressed air supply system S, in which a pneumatic scarf tan Aunt invention is integrated.
- a compressor 1 delivers into a volume V to which an air dryer cartridge 9 connects.
- the air dryer cartridge 9 dries the compressed air supplied by the compressor.
- Via a check valve 5a the dried compressed air enters the area 5 supplied by the compressed air supply system S.
- the promotion of compressed air is controlled by an electronic control unit 14.
- a solenoid valve 4 is activated. This introduces compressed air from the supplied area 5 via a check valve 8 in
- Control volume 3 This control volume 3 is both with a pneumatic control input la of the compressor 1 and with a pneumatic
- Control input 2a of a vent valve 2 connected, which vents the volume V, in which the compressor 1, via an outlet E vented. Is located
- Regeneration path (A-B-C-D-E) in the rearward direction through the air dryer 9 passed. This dry compressed air is released via a throttle 10. she leads
- the check valve 11 ensures that the control volume 3 is pressurized only via the solenoid valve 4 and not over the part (CB) of the regeneration path.
- the vent valve 2 has a second pneumatic control input 2b. This is connected to the volume V, in which the compressor 1 promotes. If too much pressure builds up there, this will be reduced by the outlet E.
- Figures 1 to 3 are in addition to the electrical control lines for
- Solenoid valves 4 and 6 the lines belonging to the control volume 3 lines drawn as dashed lines.
- the drawn as a dashed line rectangle encloses all elements that are involved in the installation of the invention
- FIG. 2 is supplemented with respect to FIG. 1 by a back-up system which maintains emergency operation in the event of a power failure.
- a pressure medium operable valve 12 is connected between the control volume 3 and an outlet 13. By tapped from the point A in the region 5 supplied by the system S pressure, the valve 12 is held against the force of the valve spring in the closed position. If this pressure falls below a predetermined value, this is a sign that in area 5 more compressed air is needed. In this case, it should be ensured that even in case of failure of the electrical supply, the promotion of
- valve 12 Compressed air is activated.
- the valve 12 is switched at decreasing control pressure at point A by the force of the valve spring in the open position and vent the control volume 3.
- the vent valve 2 is closed, and the compressor 1 is started.
- a safeguard against the build-up of a dangerous overpressure is still given, since in such a case the
- the control line to the control input of the valve 12 is operatively connected to the electrical control lines of the solenoid valves 4 and 6 to the effect that the valve 12 is a back-up for the failure of these lines. It also works together functionally with the control volume 3 by this if necessary. is vented. To illustrate this relationship, it is shown in dashed lines in Figures 2 and 3.
- FIG. 3 is supplemented with respect to FIG. 2 to the effect that electronic pressure sensors 15a and 15b are additionally provided.
- the sensor 15a monitors the pressure in the region 5 supplied by the compressed air supply system S.
- the pressure sensor 15b monitors the pressure in the control volume 3.
- the signals of the pressure sensors 15a and 15b are fed to the central control unit 14 via control lines, which are not shown for reasons of clarity.
- the first solenoid valve 4 is formed differently. In its closed position, its work is depressurized. This causes the pressure drop at the check valve 11 is maximum and this valve closes very tight. If the control volume 3 pressurized, that works too
- FIG. 4 shows a further embodiment of the invention. It differs from the embodiment shown in Figure 1 in that a series connection of two 3/2-way valves 4 and 6 is responsible for both the loading and for the venting of two independent control volumes 3a and 3b.
- the pressure in the control volume 3 a controls the control input 1 a of the compressor 1.
- the pressure in the control volume 3b controls the pneumatic control input 2a of the venting valve 2.
- the division into two independent control volumes 3a and 3b enriches the compressed air supply system by two additional functions.
- the compressor 1 can be switched off by pressurizing the control volume 3a without the venting valve 2 being opened at the same time and the pressure already built up by the compressor 1 in the volume V being lost ("supply line closing"), but on the other hand it is also possible , by Druckbeauf suppression of the control volume 3b to open the vent valve 2, while the compressor 1 remains turned on. The compressor 1 then promotes through the vent E to the outside, the extracted air waste heat of the
- compressor 1 Compresses compressor 1 and so the air path heats ("pneumatic heating"). Since these airways are in front of the air dryer 9 and the air can still be humid here, this heating can be a freezing of the airways are prevented.
- the switching state of the second solenoid valve 6 decides whether a
- Control volume is pressurized or vented.
- Control volume (3a or 3b) acts this measure respectively is determined by the
- the regeneration path A-B-C-D-E leads through the control volume 3b.
- this regeneration path and the vent valve 2 can be opened simultaneously.
- the user has a free choice as to whether the compressor 1 is switched off beforehand by enclosing a pressure in the control volume 3a or can be conveyed to the outside for the purpose of pneumatically heating the air passages. This can be made dependent on the outside temperature, for example.
- FIG. 5 The embodiment shown in Figure 5 is compared to the embodiment of Figure 4 to a bypass line 15 with a check valve 15a extended, which bridges starting from the connection between the two solenoid valves 4 and 6, the first solenoid valve 4 and into the control volume 3a.
- the check valve 15a opens in the direction of this control volume 3a.
- Solenoid valve 4 is de-energized, the second solenoid valve 6, however, still energized, the regeneration path is opened and the air dryer 9 rinsed.
- the advantage over the embodiment shown in Figure 1 is that the series connection is more compact build and that at the same time
- A, B, C, D, E points along the regeneration path
