Abstract
A spray-coating system includes a spraying implement (2) affixable to a support (4) by a tightening element (26) which is affixed to one of the implement and the support (2, 4) so as to be rotatable relative to both parts (2, 4).
Claims26
A spray-coating system, comprising:
- a spraying implement having first fluid-transmitting ducts;
- a support to which said spraying implement may be detachably affixed, said support having second fluid-transmitting ducts running therein;
- clamping means for detachably affixing said spraying implement to said support;
- fluid-transmitting duct ends of said second fluid-transmitting ducts running in the support being configured opposite fluid-transmitting duct ends of said first fluid-transmitting ducts in the spraying implement in order to transmit fluid between said first and second fluid-transmitting ducts when the spraying implement is affixed to the support;
- and
- seals at the fluid-transmitting duct ends to mutually seal the support and the spraying implement, the spraying implement being clampable by the clamping means against the support and, thereby, said seals being compressible between the spraying implement and the support;
- wherein
- the clamping means comprise a tightening element which is affixed to and rotatable about one of the spraying implement and the support and which comprises a first clamping surface;
- a second clamping surface is provided by the other of the spraying implement and the support;
- the axis of rotation of the tightening element runs in the direction of clamping in which the spraying implement and the support can be clamped;
- and
- by rotating the tightening element relative to said spraying implement and said support, the first clamping surface clamping the second clamping surface is rotated jointly with the tightening element in order to clamp the spraying implement against the support, thereby compressing the seals between the spraying implement and the support.

A spray-coating system, comprising:
- a spraying implement having at least one first fluid-transmitting duct;
- a support having at least one second fluid-transmitting duct;
- a tightening element which is rotatably attached to one of the spraying implement and the support for detachably affixing said support to said spraying implement, said tightening element comprising a first clamping surface, the other of the spraying implement and the support comprising a second clamping surface;
- said first and second fluid-transmitting ducts having first and second fluid-transmitting duct ends, respectively, said first fluid-transmitting duct ends being configured opposite said second fluid-transmitting duct ends, when said spraying implement is affixed to said support by said tightening element, to allow fluid transmission between said first and second fluid-transmitting ducts;
- and
- at least one seal between said first and second fluid-transmitting duct ends to mutually seal the support and the spraying implement, said seals being compressible between the spraying implement and the support when said spraying implement is affixed to said support by said tightening element;
- wherein
- the tightening element has an axis of rotation and is rotatable about said axis of rotation between an angular position of separation and an angular position of clamping;
- and
- a movement of said tightening element from said angular position of separation to said angular position of clamping brings the first and second clamping surfaces towards each other in the direction of said axis of rotation, so as to clamp the spraying implement against the support, thereby compressing the seal between the spraying implement and the support.
