Make pressure C (brake pressure) and is reported to electronic control unit 5.During brake inspection, by pressure sensing devices
Or examine whether anti-skidding valve gear 27 runs well by the sensor signal S thus exported.
For shown in Fig. 1 and 2, the first form of implementation of pressure system according to the invention, pressure safety device 7 sets
Count into the pressure safety part of insurance sheet form irreversibly to work.
Safety plate 7 directly prevent be more than the fixation of operating pressure C maximum value, mode is the disposable diaphragm plate 7a of safety plate
Fixed maximum value C is equivalent in responsemaxSafety plate pressure when rupture and going out into outdoor (enter atmosphere) be consequently formed
Mouth 7b.
If controlled therefore at runtime for example due to the failure in pre-control unit 21, one of 22 or relay valve 26
Brake-cylinder pressure C is promoted to maximum value Cmax, then the disposable diaphragm plate 7a of safety plate is irreversibly damaged and is entered by exhaust
Atmosphere causes enduringly to protect adjacent customer BE.Safety plate must be replaced after response (rupture).But because safety plate
It is only responded in failure, so the consuming of this replacement is reasonable.Safety plate is basic advantageously during its entire use
Upper freedom from repairs and the inspection (inspection) manually or automatically for safeguarding and also simplifying pressure system FD.By using especially insuring
The pressure safety device 7 of sheet form especially can produce caliper, brake(-holder) block and brake disc to avoid the component to brake unit
Raw irremediable damage, so that this component needs the replacement of Expenses Cost and time.Used safety plate can be from one
It is freely selected in the available safety plate of group, the safety plate is different from each other in terms of its respective response pressure value.Such as use guarantor
Dangerous piece is designed by its structure operating pressure C being determined as one between 1 to the value between 6Bar.
Second form of implementation of pressure system according to the invention shown in Fig. 3 is only distinguished in terms of pressure safety device
In the first form of implementation.
For the second form of implementation shown in Fig. 3 of pressure system according to the invention, pressure safety device 28 is designed to
By the pressure safety part 29 of insurance sheet form irreversibly to work and the pressure safety part of safety valve form reversibly to work
30 combinations constituted, the safety valve connect behind the pressure safety part 29 irreversibly to work.The pressure etc. of safe response valve
In or lower than preferred safety plate 29 response pressure Cmax.If therefore operating pressure C is promoted to maximum value C in operationmax, then protect
The disposable diaphragm plate 29a of dangerous piece 29 ruptures so that safety valve 30 followed at present also responsive to and formed into outdoor
Outlet, so that operating pressure C quickly declines.
Different from safety plate 29, safety valve 30 returns to its initial position after ventilation, without replacing.
When carrying out functional check to pressure system FD, the shape of safety plate 7 or 29 is checked in a manner of not shown further
State.The state and safety plate 7 or 29 of anti-skidding valve gear 27 especially can be checked in the anti-skidding test run of brake inspection
State.Here, safety plate 7 or 29 (that is need not promote operating pressure until maximum value especially by normal pressure
Cmax) tested in terms of its function or in terms of the thus reaction of caused pressure system FD.
The present invention is not limited to forms of implementation shown in fluid-pressure system.Another customer, for example, car door equipment or
Toilet facility especially can be applied operating pressure in the inlet of its actuator, and the operating pressure is in correspondingly different designs
The exit of control device is controlled.It is also important that the pressure safety device for especially insuring sheet form is connected to fluid hose
In the branch of section and the maximum value of the fixation more than operating pressure is prevented, the branch makes outlet and the customer of control device
Actuator entrance connection.
