MODULAR ZUSAMMENSETZBARES DRUCKLUFTAUFBEREITUNGSSYSTEM FUER EINE PNEUMATIK

摘要

The invention relates to a modularly assemblable compressed air preparation system for a pneumatic mechanism with at least two mutually interchangeable connectable modules (10, 10', 10''), especially valve, filter, oiler or line connection modules having a basic member (14; 14') with module-specific components, whereby the basic member (14; 14') has an air channel (24; 24') which interconnects an inlet aperture (20; 20') of a first lateral surface (26; 26') and at least one outlet aperture (22; 22') in another lateral surface (28; 28') preferably opposite the first (26, 26') and for each lateral surface (26, 28; 26', 28') with an aperture (20, 22; 20', 22') has two tension springs (32, 34; 32', 34') with an inclined tension surface (33, 35; 33', 35') which are diametrically opposite the relevant aperture (20, 22; 20', 22') and with two tension bodies (52, 80) per pair of modules (10, 10'; 10', 10'') which have V-shaped tension counter-surfaces (60, 61; 85, 86) inclined towards one another in which the corresponding tension springs (32, 34; 32', 34') of adjacent basic members (14; 14') fit and can be mutually tensioned in the diametrical direction in relation to the apertures (20, 22; 20', 22') so that the mutually allocated tension surfaces (33, 35; 33', 35') slide on the tension counter-surfaces (60, 61; 85, 86) and the basic members (14; 14') are mutually tensioned axially in relation to the apertures (20, 22; 20' 22') and releasably interconnected, whereby an airtight connection with the air guide channels (24, 24') is formed via at least one seal (68). In order to facilitate simple ad more rapid securing of two modules together, the basic member (14; 14') bordering the mutually directed lateral surfaces (28; 26') passes through and has a securing projection (70), the second tensioning body (80) has a tensioning shoe (82) and a pivotable eccentric lever (102) which can be engaged with the securing projection (70) and which works with a guide surface (94) of the tensioning shoe (82) and the eccentric lever (102) can be pivoted from an engaged position in which the second tension body (80) can be separated from the first into a tensioning position in which the second tension body (80) is secured to the first with the clamping of the basic member (14; 14').
