    • Shaving apparatus having at least one cutting unit (3) with an external cutting member (4) and a rotatable internal cutting member (6) each having cooperating cutting edges (8,9) forming bearing surfaces of a first bearing, said external and internal cutting member (4,6) having a second bearing with bearing surfaces (14,17). To minimize the friction between the cutting edges (8,9), means (13) with visco-elastic properties are provided between the two bearings, so that during operation the distance between the bearing surfaces (8,9) of the first bearing adjusts oneself to the distance between the bearing surfaces (14,17) of the second bearing. During cutting of hairs the means with visco-elastic properties behave as a stiff element whereas during periods in which no hairs are cut these means behave relatively soft so that the cutting gaps between the cutting edges are closed.
    • 剃须装置具有至少一个具有外部切割构件(4)和可旋转内部切割构件(6)的切割单元(3),每个切割单元具有形成第一轴承的支承表面的协作切割边缘(8,9),所述外部和内部 切割构件(4,6)具有带有支承表面(14,17)的第二轴承。 为了使切割边缘(8,9)之间的摩擦最小化,在两个轴承之间设置具有粘弹特性的装置(13),使得在操作期间第一轴承的轴承表面(8,9)之间的距离调节 自己与第二轴承的轴承表面(14,17)之间的距离。 在切割毛发期间,具有粘弹性的装置表现为刚性元件,而在没有毛发切割的期间,这些装置表现出相对较软,因此切割边缘之间的切割间隙关闭。
