Embodiment Construction

[0048] in figure 1 The compressed air supply device 1 shown in is installed on a commercial vehicle and is used to supply compressed air consumers, such as pneumatic or electro-pneumatic service brakes, parking brakes, air suspension devices and / or door controls The device supplies compressed air.

[0049] The compressed air supply device 1 has an air drying device 2 with an air drying cylinder 4, which is detachably and replaceably fixed on a first housing 6, which contains other components of the air drying device 2 , Such as the check valve not visible here.

[0050] The first housing 6 is made of aluminum, for example, and is produced by a die-casting method. The air drying cylinder or the air drying core 4 is detachably fixed on the first housing 6 by means of a fixing device 8 such as a bayonet locking mechanism. The components of the bayonet-type locking mechanism are also made of metal, and all interfaces of the first housing 6 are the same as the interface 10 of a compre...

Abstract

The invention relates to a compressed air supply device (1) for a vehicle compressed air installation, comprising at least one air drying device (2) with an air drying cylinder (4), a valve device with a multi-circuit protection valve ( 26), pressure limiter, open-loop control and closed-loop control electronics (60) as a structural component and comprising a plurality of housings (6, 20, 22, 36, 62), in which the aforementioned structures are arranged components. The invention provides that at least one housing (20, 22, 36, 70) of the plurality of housings is made of plastic. As a result, the compressed air supply device has a lower weight and is easier to manufacture.

Description

Technical field [0001] The present invention relates to a compressed air supply device for vehicle compressed air equipment, which includes at least one air drying device with an air drying cylinder, a valve device with a multi-circuit protection valve and other valves when necessary, a pressure limiter or The voltage regulator, the open-loop control and the closed-loop control electronic device are used as components or structural components and include a plurality of housings or housing components in which the aforementioned components or structural components are arranged. [0002] In addition, the present invention relates to a vehicle compressed air equipment supplied with compressed air by the compressed air supply device. Background technique [0003] For example, DE 198 61 222 B4 discloses a compressed air supply device. There, an electro-pneumatic pressure regulator, a four-circuit protection valve, a plurality of electromechanical pressure control devices, a pressure sen...
