The device (10) for the release of material (202) for
processing, comprises an
actuator device (800), by means of which a guide rod (1), mounted for
axial displacement, provided on the front thereof with a threaded pin (12) for connection to a
piston (5), may be introduced into a cylinder (9; 309), such that the
piston (5) acts on the material (202) for
processing in the cylinder (9; 309) and forces the same from the cylinder (9; 309). According to the invention, the
piston (5) comprises two opposing faces (5A, 5B), the first face (5A) of which acts on the material (202) for
processing, housed in a bag (200), introduced into the cylinder (9) and the second face (5B) of which acts on material (202) for processing housed in the cylinder (309) in a
cartridge (300) introduced into the device (10). The device (10) thus permits, after corresponding
assembly of the piston (5), the processing of a bag introduced into the cylinder (9), or a
cartridge (300) which may be inserted in the device (10).
