Abstract
(DE)
Die Erfindung betrifft eine Schalteinheit zum miteinander Verschalten einer ersten pneumatischen Einheit und einer zweiten pneumatischen Einheit eines pneumatischen Systems, wobei die Schalteinheit einen Grundkörper mit einer sich durch den Grundkörper erstreckenden Kanalstruktur, einem ersten und einem zweiten Einlass zum Einleiten eines Drucks in die Kanalstruktur, einem ersten und einem zweiten Auslass zum Ausleiten zumindest eines Teils des Drucks aus der Kanalstruktur sowie einem ersten und zweiten Ventil, wobei der erste Einlass über einen ersten Kanal mit dem ersten Auslass durch Einstellen einer ersten Schaltstellung des ersten Ventils oder über einen zweiten Kanal mit dem zweiten Auslass durch Einstellen einer zweiten Schaltstellung des ersten Ventils in eine Druckaustauschverbindung bringbar ist, und wobei der zweite Einlass über einen dritten Kanal mit dem ersten Auslass durch Einstellen einer ersten Schaltstellung des zweiten Ventils oder über einen vierten Kanal mit dem zweiten Auslass durch Einstellen einer zweiten Schaltstellung des zweiten Ventils in eine Druckaustauschverbindung bringbar ist.
(EN)
The invention relates to a switching unit for connecting a first pneumatic unit and a second pneumatic unit of a pneumatic system together, the switching unit comprising a main body having: a duct structure which extends through the main body; a first and a second inlet for introducing a pressure into the duct structure; a first and a second outlet for discharging at least some of the pressure from the duct structure; and a first and a second valve; wherein the first inlet can be brought into a pressure-exchange connection to the first outlet via a first duct by setting a first switch position of the first valve or to the second outlet via a second duct by setting a second switch position of the first valve, and wherein the second inlet can be brought into a pressure-exchange connection to the first outlet via a third duct by setting a first switch position of the second valve or to the second outlet via a fourth duct by setting a second switch position of the second valve.
(FR)
L'invention concerne une unité de commutation permettant d'interconnecter une première unité pneumatique et une seconde unité pneumatique d'un système pneumatique. L'unité de commutation comprend un corps de base comportant une structure de canal qui s'étend à travers le corps de base, une première et une seconde entrée pour l'introduction d'une pression dans la structure de canal, une première et une seconde sortie pour l'évacuation d'au moins une partie de la pression de la structure de canal, ainsi qu'une première et une seconde soupape. La première entrée peut être amenée en liaison d'échange de pression avec la première sortie par l'intermédiaire d'un premier canal, en réglant une première position de commutation de la première soupape ou avec la seconde sortie par l'intermédiaire d'un deuxième canal, en réglant une seconde position de commutation de la première soupape, et la seconde entrée peut être amenée en liaison d'échange de pression avec la première sortie par l'intermédiaire d'un troisième canal, en réglant une première position de commutation de la seconde soupape ou, avec la seconde sortie par l'intermédiaire d'un quatrième canal, en réglant une seconde position de commutation de la seconde soupape.
