Abstract
A rapid-action connection element for a compressed air hose (3) includes a filter (5) located in the discharge casing (4) for sealing a flow cross-section, a flow-through pressure piston (7) extending, at least partially into the discharge casing (4) and displaceable, within limits between outward position remote from the filter (5) in which the pressure piston (7) is sealed with respect to the discharge casing (4), and an inward position adjacent to the filter (5) in which the pressure piston (7) is open with respect to the discharge casing (4) for flow therebetween, and a flow-through rapid-action coupling member (6a) connected with the pressure piston (7).
Claims7
A rapid-action connection element for a compressed air hose (3), comprising a flow-through discharge casing (4);
- a filter (5) located in the discharge casing (4) for sealing a flow cross-section with a compressed air flow being filtered therethrough;
- a flow-through pressure piston (7) extending, at least partially into the discharge casing (4), displaceable, within limits, in opposite directions, and having an outward position remote from the filter (5) in which the pressure piston (7) is sealed with respect to the discharge casing (4), and an inward position adjacent to but spaced from the filter (5) in which the pressure piston (7) is open with respect to the discharge casing (4) for flow of the medium therebetween;
- and a flow-through rapid-action coupling member (6a) connected with the pressure piston (7).
