Abstract

a. Cylindre à membrane pour dispositifs de commande fonctionnant par pression, comprenant un boîtier et une membrane en forme de pot, en caoutchouc ou en un matériau semblable à du caoutchouc, pourvue d'un rebord périphérique de serrage et mobile librement avec un disque à membrane. b. Le boîtier 2 de ce cylindre présente sur sa périphérie un diamètre sensiblement constant pour réduire ou minimiser la surface d'appui de la membrane sur le boîtier. La course maximale du cylindre à membrane est supérieure au double de la hauteur H de celle-ci plus son épaisseur de paroi. Or cette membrane 3, qui se supporte au moins partiellement dans la zone de la course maximale, s'appuie entre le rebord de serrage 4 et le disque 7 et pratiquement seulement sur ce disque c. Ce cylindre à membrane peut être utilisé en particulier dans des installations de freinage à air comprimé pour véhicule automobile.at. Diaphragm cylinder for pressure-operated control devices, comprising a housing and a pot-shaped diaphragm, made of rubber or a rubber-like material, provided with a peripheral clamping rim and freely movable with a diaphragm disc. b. The housing 2 of this cylinder has on its periphery a substantially constant diameter to reduce or minimize the bearing surface of the membrane on the housing. The maximum stroke of the membrane cylinder is greater than twice the height H thereof plus its wall thickness. Now this membrane 3, which is supported at least partially in the zone of the maximum stroke, rests between the clamping flange 4 and the disc 7 and practically only on this disc c. This membrane cylinder can be used in particular in compressed air braking systems for motor vehicles.
