Abstract (en)
[origin: EP0310842A1] In this piston press for pressing liquid out of a material for pressing, especially out of a batch (14) of wet textiles, by means of a press ram (13) which can be moved onto the material for pressing by the piston of a pressure cylinder (10), the cylindrical casing (15) receiving the material for pressing can be closed off at the bottom by a perforated pressure plate (16). In this cylindrical casing (15), into which the material for pressing and the press ram (13) can be introduced in succession from above, the press ram (13) is connected to the orifice edge (17) of a pot-shaped elastically flexible cushion body (18). Furthermore, the press ram (13) has a connection piece (27) which can be connected to a water system in order to introduce water into the cushion body (18), the bottom of which forms a diaphragm (35) which can be pressed against the material for pressing. A line (28, 31) connects the connection piece (27) permanently to the water system, and there is a valve device (32, 33) which can be actuated from a location outside the path of movement of the press ram (13) and which can be switched selectively for the supply of water or for the removal of air. <IMAGE>
