Abstract

Vorgeschlagen wird ein Betätigungszylinder, vorzugsweise für druckluftbetriebene Bremsanlagen. Dieser weist ein Zylindergehäuse (6) mit darin auf einer gemeinsamen Längsachse hintereinander angeordneten ersten und zweiten Druckräumen (8, 9) auf. Die Druckräume sind jeweils mit einer diese an einer Seite axial begrenzenden beweglichen Wand (3, 4; 12, 13) versehen. Eine Feder (14) beaufschlagt die bewegliche Wand (12, 13) des zweiten Druckraums (9). Zur Aufhebung der Wirkung der Feder ist ferner ein Schraubelement (30) mit einem mit der Druckplatte (13) mechanisch koppelbaren Verbindungsabschnitt (31) sowie einem aus einer Abschlußwand (15) des Zylindergehäuses (6) herausführenden Gewindeabschnitt (33) vorhanden. Auf dem Gewindeabschnitt ist eine sich von außen gegen die Abschlußwand (15) abstützende Gewindemutter (35) schraubbar. Zur Unterbringung des Schraubelementes (30) bei Nichtbenutzung wird vorgeschlagen, daß der Verbindungsabschnitt (31) des Schraubelements (30) über lediglich einen Teil seines Umfangs mit mindestens einer radialen Erweiterung (31a, 31b) versehen ist. Der Rand der der Hindurchführung des Schraubelements (30) dienenden Öffnung in der Abschlußwand (15) erstreckt sich zumindest über einen Teilsektor (37a, 37b) seines Gesamtumfangs bis nahe an den Gewindeabschnitt (33). An der Innenseite des Teilsektors (37a, 37b) ist eine Abstützfläche ausgebildet, an der sich die radiale Erweiterung (31a, 31b) des Schraubelements (30) bei dessen Nichtgebrauch abstützen kann.
