  • Patent number: 9931464
    Abstract: An injection device (10) for administering a liquid has a barrel (12) with an outlet (20) for the liquid, and a piston (14) arranged in the barrel (12). The piston is designed to force the liquid out from the outlet (20) by displacement into the barrel (12). The injection device (10) has an overpressure protection with a sensor (24) and with an actuator (26). The sensor (24) detects the pressure of the liquid in the barrel (12) directly or indirectly. The actuator (26) prevents a further increase in the pressure of the liquid.

  • Patent number: 5180538
    Abstract: Device and method for feeding molten metal for the pressure casting of metal products.The device for feeding molten metal to a mould 1 of a continuous pressure-casting installation comprises a vessel 2 equipped with a cover 7 carrying a spout 3, the said vessel resting on a frame 4 and comprising a framework 9 for supporting a ladle 10 of molten metal, means for weighing the said ladle and means 20 for raising the said framework.The casting method implementing this device is characterized in that, during the cast, when the quantity of metal in the ladle 10 is greater than a specific quantity, the ladle is held in a low position (position according to reference 32) and, when the quantity of metal becomes less than the said specific quantity, the ladle is raised (position 32') so as to hold the lower end 31 of the spout below the level of the metal contained in the ladle.
