  • Patent number: 4730652
    Abstract: The fuel filling system includes double pipe fuel delivery and tank venting plumbing. Both fuel delivery pipe and tank venting pipe are flexible and communicate with the gas tank through normally closed check valves. An inlet housing defines a vent cut-off chamber which communicates with the tank venting pipe, and also includes an annular nozzle embracing seal for isolating the end of the gas pump nozzle from the vent cut-off chamber. The gas tank is thus fully sealed by the check valves during driving, so that fuel will not spill from the tank should the filling system plumbing become ruptured or should the vehicle become overturned as a result of a collision. Fuel is introduced into the tank under positive pressure provided by the filling station fuel pump. Under pumping pressure, the check valves opens to permit the inflow of fuel and the outflow of air displaced from within the tank.

  • Patent number: 4723581
    Abstract: A process and apparatus for drawing off deformable masses containing air, such as sausage masses. The mass is transferred in a stream from a supply space into a filling cylinder where a vacuum is generated relative to the space to remove air from the mass, and the transferred mass is then ejected from the filling cylinder by means of a piston. To transfer the mass quickly and remove air from it completely, the mass stream is guided, during its transfer into the filling cylinder in such a way that, as it enters the filling cylinder, it first moves towards the cylinder wall at an angle to the direction of the piston. Moreover, during filling the level of mass in the filling cylinder is maintained at an essentially constant filling height so that a constant volume of free space remains above the mass in the filling cylinder.
