The apparatus ensures that the pressure of the synthetic resin components, in particular polyurethane-forming components, is kept constant. This is achieved by a device which generates or makes available a constant force, which is then used for the purpose of keeping the pressure constant in each component line. This compensates for pressure fluctuations, which can occur, in particular during mixi...
