Filed: 2000-12-14
Abstract: A compression chamber (14) is formed in a housing (2) around a closing piston (5), and defined upstream by the end wall of the housing and downstream by a peripheral sealing gasket (7) carried by the piston. The closing piston has an internal passage (9) which has an inlet (9a) open into the compression chamber, and an outlet (9b) communicating with an injection outlet. The injection outlet of the connector is located downstream from the gasket which is carried by the rigid and non-deformable piston. The housing is defined in a case (1) and accessible through an injection inlet duct (3) open into the housing through the housing end wall. The housing communicates with the injection outlet. The inlet duct is designed to enable the injection head to be inserted with lateral sealing into the duct towards the housing. The piston can move in the housing and inlet duct between upstream position and downstream position. A spring (12) urges the piston towards the upstream position. The compression chamber is accessible to the liquid injected by the injection head, and communicates with the outlet of the connector. The volume of the compression chamber varies with the displacement of the closing piston so that the withdrawing of the injection head causes the volume of the compression chamber to reduce and excess liquid in the chamber is expelled towards the injection outlet.

Abstract: The invention relates to two-component polyurethane systems, consisting of one polyol component and one isocyanate component. Said polyol component contains at least two amines A1 and A2, the reactivity R1 of amine A1 with isocyanate being considerably greater than the reactivity R2 of amine A2 with isocyanate. As a result, two time-delayed reactions take place. This gives the inventive systems the desired low level of viscosity, and the thixotropic properties which prevent even thick layers from sliding off of vertical surfaces. The inventive two-component polyurethane systems can be used for producing cubing models, master models and similar in the automobile industry and for producing structured bodies and thick films and sealing beads.
