VALVE AND SUPPLYING DEVICE FOR FILLING A MOULDING CAVITY WITH A POLYMERISABLE MATERIAL

摘要

The inventive valve comprises a dosing chamber (20) connected to a dispenser (16) provided with input and output orifices (7, 8) which are connected to said dosing chamber (20) when the dispenser (16) is in a position (21), an injection orifice (9) being isolated. When the dispenser (16) is in a position (23), the input and output orifices (7,8) are isolated from the dosing chamber (20) and from an injection orifice (9) which are connected to each other. In addition, said device comprises a source of polymerisable material which is provided with a container (5), a continuous pump (6) and a control unit (3) for control elements (19, 24) of the valve (2).
