Abstract (en)

[origin: WO2020016383A1] The invention relates to a compressed-air-operated expulsion device (10) for expelling objects (14) or fluid materials from a reservoir by means of a drive piston (18), which can be impinged upon by a gas volume compressible in a compression chamber (23). The drive piston (18) has a drive device for compressing the gas volume and a release device for decompressing the compressed gas volume. The compression chamber (23) has a venting device for temporarily venting the compression chamber (23) and a filling device (41) for filling the vented compression chamber (23) with compressed air.
