    • In a press with a plunger which is supported by an elastically deformable support structure so as to be linearly movable but otherwise rigidly engaged and with a drive arrangement for the controlled movement of the plunger, the drive arrangement includes no friction or antifriction support joints so that the plunger guide structure is not affected by position errors generated by oil films in bearings or wear of bearings generated by the high press forces effective during operation of the press which could squeeze oil films out of bearing gaps.
    • 在具有柱塞的压力机中,该柱塞由可弹性变形的支撑结构支撑,以便可直线移动但是以其它方式刚性地接合,并且具有用于柱塞受控运动的驱动装置,该驱动装置不包括摩擦或减摩支撑接头, 柱塞导向结构不受由轴承中的油膜产生的位置误差或由压力机操作期间有效的高压力产生的轴承磨损的影响,这可能会将油膜挤压出轴承间隙。
