Problems solved by technology

[0006] Since the sealing element, typically a square seal ring, when fastened between the cartridge bottom plate and the housing of the compressed air production unit as is known from practice, must rotate together during tightening, due to different frictional influences during tightening Large fluctuations in the torque occur and damage or twisting of the sealing element occurs, which in turn leads to leakage

Embodiment Construction

[0028] figure 1 An enlarged detail view of a section of a desiccant cartridge according to an exemplary embodiment of the invention is shown here. figure 1 In particular, an enlarged section of the region of the desiccant cartridge 1 lying radially on the outside and below is shown. The interior of the desiccant cartridge 1 can be constructed in a manner known per se, for example as described in the laid-open documents DE 10 2013 103 066 A1, DE 10 2012 105 137 A1 and DE 10 2007 034 435 A1. For example, the reference numeral 14 designates an oil filter formed by a fleece and the reference numeral 15 designates an inner container for a desiccant, of which only a small part can be seen.

[0029] The cartridge housing of the desiccant cartridge has, in a manner known per se, a basin-shaped or cup-shaped cover 2 and a support element 3 , for example in the form of a bottom plate, which caps the cartridge housing upwardly, the support element Restrain the cartridge housing downwar...

Abstract

The invention relates to a desiccant cartridge for detachable fastening on a compressed air production system of a vehicle, in particular a commercial vehicle. The invention also relates to a device for releasably fastening a desiccant cartridge on a housing of a compressed air production device of a vehicle. The desiccant cartridge comprises a cartridge housing containing the desiccant, with a cover that constrains the cartridge housing upwards, and a bracket element that constrains the cartridge housing downwards, and the cartridge housing is in an assembled position is releasably fastened to the housing of the compressed air production system. The desiccant cartridge also comprises a sealing groove arranged at the underside of the support element, a sealing element arranged in the sealing groove and a fluid connection between the sealing groove and the pressure-loaded space inside the desiccant cartridge, through which the fluid The connection can act on the sealing element in the assembled position of the desiccant cartridge with the system pressure of the compressed air production system.

Description

technical field [0001] The invention relates to a desiccant cartridge for detachable fastening on a compressed air production system of a vehicle, in particular a commercial vehicle. The invention also relates to a device for releasably fastening a desiccant cartridge on a housing of a compressed air production device of a vehicle. Background technique [0002] In particular, compressed air systems in commercial vehicles require so-called compressed air preparation systems, hereinafter also referred to as air preparation systems, if they are connected downstream of an air compressor. In particular, the air is dried and filtered, and the oil components are separated off. These processes all take place in so-called desiccant cartridges, roughly speaking, consisting of a bottom plate with openings for the flow of air through and a cup-shaped or basin-shaped cover, the bottom plate and The covers are fixedly connected to each other. Moisture-adsorbing granules are present the...
