Abstract: The invention relates to a controller for a hydraulic press, comprising a pressing cylinder (1), a reservoir (2), a valve group (3), a pressure medium reservoir (7) and a hydraulic pump (6), connected together by means of a cylinder line (4), a reservoir line (5) and a tank line (8). According to the invention, a pressure converter (9) is arranged on the valve group (3), which may operate as a pressure amplifier or pressure reducer. The particular mode of action of said controller is achieved whereby the valve group (3) comprises a pre-press valve (11), a low-pressure chamber outlet valve (12), a low-pressure chamber inlet valve (13), a main press valve (14), a closing valve (15), a pressure release valve (16) and a 3-way valve (17), which may be operated by a particular control sequence. Said invention is applicable in hydraulic presses and of particular advantage in presses for the forming of ceramic pieces such as tiles.

Abstract: The invention relates to a press for ceramic formed parts, in particular tiles, whereby there is disposed within an upper beam of the press an oil storage container in the form of a storage volume chamber integrally incorporated in the upper beam. A filling valve is provided between the storage volume chamber and the main press cylinder which is also integrally incorporated in the upper beam. The main press cylinder is formed as a main press chamber and has the filling valve which is mounted on the chamber wall by way of holding flange. A press of the aforedescribed construction is downtime-friendly and maintenance-friendly and has a rapid cycling time and a high output. Moreover, it manufactures a good quality of pressed parts.
