| 摘要 |
The present invention encompasses a pneumatic system (6) with a pressure source (8) adapted for generating a medium under pneumatic pressure, a control valve (2) coordinated with the pressure source, via a first conduit (A), a piston-cylinder arrangement or a "motor" (1), whose working chamber (1e) is coordinated, via a second conduit (B), with said control valve (2) and whose low-pressure or return chamber (1f) is coordinated, via a third conduit (C), with one side of a coupling arrangement (10A') whose other side is coordinated, via a fourth conduit (D), with said pressure source (8). Said coupling arrangement (10A') is in the form of a unit (10A) coordinated with the piston-cylinder arrangement (1) but discrete or separated from the piston-cylinder arrangement (1), Within said unit (10A) and extending between connections associated with the unit there is disposed at least one direct or indirect coupling-in of a high-pressure regulator (11) and a low-pressure regulator (12). |
