Abstract (en)
[origin: US4694977A] A vacuum-tight and pressure-tight closed storage space in a container is constructionally combined with a thrust piston pump projecting thereinto and a drag piston slidably guided therein and in the initial position of the thrust piston pump is hermetically sealed by an exhaust valve mechanically closed in forcibly controlled manner. The drag piston is adapted to the thrust piston pump in such a way that the storage space can be emptied substantially free with the thrust piston pump.
