In the case of a pressure capsule for delivering assembly foams, in particular one-component polyurethane foam, the surround of which has a cylinder, a preferably turned-in bottom and a dome-like upper part with a closure, fitted into which is a valve for delivering the capsule filling comprising a blowing agent and foaming agent, to restrict the escape of blowing agent into the atmosphere and to make the application technology easier, it is proposed to guide in the interior on the wall of the cylinder of the surround the skirt of a piston in overhung arrangement, which piston floats on the blowing agent and foaming agent filling, accommodated in separate capsule spaces, and separates the blowing agent space, enclosed by the capsule bottom and a variable lower length of the cylinder wall, from the space which lies above, receives the foaming agent and is enclosed by the piston head and the remaining length of the cylinder and the closure. |
