Problems solved by technology

[0006] However, it is unsatisfactory in this state of the art that such directional valves can become stuck and then a reliable switching to the relevant pressure can no longer be guaranteed
In addition, the reversing valve is a valve that requires additional piping, which requires a certain cost

Embodiment Construction

[0042] exist figure 1 An excerpt from a schematic circuit diagram of an electropneumatic service brake device 1 as a preferred embodiment of the compressed air device according to the invention is given in . For the electropneumatic service brake system 1 , for example in the form of an electronically regulated brake system (EBS) with a brake pressure regulator, a single-channel pressure regulator, here for example a front axle of a commercial vehicle, is shown for reasons of scale. Module 2 and one foot brake module 4. The pressure regulation module 2 is assigned to the two wheels of the front axle and regulates the pneumatic brake pressure in the two pneumatic brake cylinders 6 of the front axle in parallel.

[0043] The pressure regulation module comprises a relay valve arrangement 8, for example in the form of a double relay valve, two reservoir ports 10, 12, two check valves 14, 16, a valve with inlet valve 20 and outlet valve 22 respectively as two Inlet / discharge-sole...

Abstract

The invention relates to a compressed-air device for vehicles, comprising an at least double-circuit pneumatic or electro-pneumatic brake mechanism (1) that includes at least one relay valve mechanism (8), an operating connection (26) of which is directly or indirectly connected to at least one pneumatic brake cylinder (6) of a first braking circuit, and a supply connection (38) of which is connected to at least a first compressed-air supply (36) associated with said first braking circuit.

Description

technical field [0001] The invention relates to a compressed air device for vehicles according to the preamble of claim 1, comprising an at least two-circuit pneumatic or electropneumatic braking device with at least one relay Valve device, the working port of the relay valve device is directly or indirectly connected to at least one pneumatic brake cylinder of a first brake circuit and the reservoir port is connected to at least one first compressed air reservoir assigned to the first brake circuit device connection. Background technique [0002] A compressed air device of this type is known, for example, from DE 199 32 470 A1 and is embodied there as a compressed air-operated vehicle brake system for commercial vehicles. In this case, the first electropneumatic service brake circuit acts as the rear axle brake circuit for the two wheels of the rear axle and the second electropneumatic service brake circuit acts as the front axle for the two wheels of the front axle - bra...
