Abstract: A shaving apparatus having at least one cutting unit with an external cutting member and a rotatable internal cutting member each the external and internal cutting members having cooperating cutting edges forming bearing surfaces of a first bearing, and a second bearing with bearing surfaces. To minimize the friction between the cutting edges, a support device having visco-elastic properties is provided between the two bearings. During operation, the distance between the bearing surfaces of the first bearing adjusts to the distance between the bearing surfaces of the second bearing. During cutting of hairs, the support device behaves as a stiff element whereas during periods in which no hairs are cut, the support device behaves relatively soft so that the cutting gaps between the cutting edges are closed.

Abstract: Shaving apparatus having at least one cutting unit with an external cutting member and a movable internal cutting member. An energy-dissipating system is provided between mutually movable parts of the internal or an external cutting member to reduce the bouncing effect between the internal and external cutting member after cutting a hair. Such an energy-dissipating system may for example be an element with visco-elastic properties.

Abstract: 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.

Abstract: Shaving apparatus having at least one cutting unit (3) with an external cutting member (4) and a movable internal cutting member (6). To reduce the bouncing effect between the internal and external cutting member after cutting a hair, an energy-dissipating system (22) is provided between mutually movable parts of the internal (6) or external cutting member (4). Such an energy-dissipating system can for example be an element (22) with visco-elastic properties.

Abstract: A shaving apparatus with an external cutting member (4) and an internal cutting member which can be driven into rotation relative to the external member. The external cutting member (4) has an annular region (8) with hair-trapping apertures (5) and a skin support region (9) in a central area surrounded by the annular region. To improve the shaving performance, the skin support area is provided with ridges 10.

Abstract: System of two types of shaving apparatus, each having a housing (1) on which a holder (2) for at least one cutting unit (3) can be mounted, which cutting unit comprises an external cutting element (4) and an internal cutting element (5) rotatably driven relative to the external cutting element, which cutting unit (3) can be detachably mounted in an opening (8) of the holder (2). The external cutting element (4) of only one of the two types of shaving apparatus is provided with at least one recess (11), and the holder (2) of the type of shaving apparatus in question is provided with at least one cam (12) which corresponds to the recess (11) of the external cutting element (4).

Abstract: Shaving apparatus with an external cutting member (4) and an internal cutting member which can be driven into rotation relative thereto, said external cutting member (4) having an annular region (8) with hair-trapping apertures (5) and a skin support region (9) inside the annular region. To improve the shaving performance, the skin support area is provided with ridges 10.
