摘要： A dry-shaving apparatus comprises a housing; a longitudinally extending shear plate; a holder for the shear plate, the holder being removable from the housing; and a longitudinally extending cutter rotatable relative to the shear plate. The cutter includes a carrier having cutting elements movable in a substantially radial direction relative to the carrier. Each cutting element has a cutting edge at its radial end, such radial ends being in contact with the shear plate during only a part of a revolution of the cutter and being clear of other parts of the apparatus during another part of the cutter revolution. A guide wall provided on the housing adjoins the shear plate, the radial ends of the cutting elements also being in contact during a further part of the cutter revolution with such guide wall.

摘要： The disclosure relates to a shaving apparatus having a shear plate with hair entry apertures and a drivable cutting unit with at least one cutting element provided with a cutting edge. Owing to the presence of the shear plate a shaving apparatus of this type does not allow the hairs to be shaved as closely to the skin as a shaving apparatus without such a shear plate, where the cutting element is in direct contact with the skin. In order to eliminate this drawback a construction is proposed in which the cutting element is provided with a hair pulling element which leads in the direction of the driving and which is immobile relative to the cutting element.
摘要翻译：本公开涉及具有具有毛发进入孔的剪切板的剃刮装置和具有至少一个具有切割边缘的切割元件的可驱动切割单元。由于剪切板的存在，这种类型的剃须装置不允许毛发像剃须装置一样像皮肤一样被剃光，而没有这种剪切板，其中切割元件与皮肤直接接触。为了消除这个缺陷，提出了一种结构，其中切割元件设置有在驱动方向上引导并且相对于切割元件不动的牵引元件。

摘要： A dry-shaving apparatus comprising a housing supporting a cutter for rotation is provided in which the cutting elements of a rotatable cutter follow a constrained path defined by the shear plate and, when the elements are clear of the shear plate, follow a free path in the form of a first circular arc as part of a revolution during rotation of the cutter. The shear plate includes peripheral portions wherein the first peripheral portion is proximate to the point where the free path changes into the constrained path and the second peripheral portion is proximate to the point where the constrained path changes into the free path, the peripheral portions adjoining the housing and a central portion which in a sectional view transverse to the axis of rotation to the cutter is curved in conformity with a second circular arc which is concentric with the first circular arc and in which the centers of the two circular arcs coincide but in which the radius of the second circular arc is smaller than the radius of the first circular arc.To avoid collision, undesired vibrations and damage to parts during the change from the free path to the constrained path, the shear plate also comprises a curved transition portion adjoining the first peripheral portion and the central portion which is given a curved shape with a radius of curvature larger than the radius of curvature of the central portion.
摘要翻译：提供了一种包括支撑用于旋转的切割器的壳体的干燥剃须装置，其中可旋转切割器的切割元件遵循由剪切板限定的约束路径，并且当元件离开剪切板时，沿着自由路径第一圆弧的形式作为在切割器旋转期间的旋转的一部分。剪切板包括周边部分，其中第一周边部分靠近自由路径变成约束路径的点，并且第二周边部分靠近受约束路径变为自由路径的点，周边部分邻接壳体和在与切割器的旋转轴线横切的剖视图中的中心部分与第一圆弧弧形地弯曲，该第二圆弧与第一圆弧同心，并且其中两个圆弧的中心重合，但其中第二圆弧的半径小于第一圆弧的半径。为了避免在从自由路径到约束路径的变化期间碰撞，不期望的振动和对零件的损坏，剪切板还包括邻接第一周边部分和中心部分的弯曲过渡部分，该弯曲过渡部分被赋予具有半径为曲率大于中心部分的曲率半径。

摘要： A separator device (3) provided with a cyclone chamber (11, 79) for separating solid and/or liquid particles from a gas flow. The cyclone chamber (11, 79) has an upper wall (49) in which an outlet opening (15) is present, and a substantially rotationally symmetrical side wall (47, 81) in which an inlet opening (13) is present adjacent the upper wall (49). A discharge opening (17, 85) for the separated solid and/or liquid particles is present at a side (55, 83) of the cyclone chamber (11, 79) remote from the upper wall (49). According to the invention, a rotatable annular centrifugal unit (61, 87) is arranged in the cyclone chamber (11, 79) around the outlet opening (15) near the upper wall (49), by means of which unit a short-circuit flow running directly from the inlet opening (13) to the outlet opening (15) in the cyclone chamber (11, 79) is prevented. The efficiency of the separator device (3) is considerably improved thereby. In a first embodiment, the centrifugal unit (61) comprises a rotatable annular disc (65) positioned adjacent and parallel to the upper wall (49). In a second embodiment, the centrifugal unit (87) comprises a rotatable rim of blades (89) which is partly countersunk into a recess (95) in the upper wall (49). The separator device (3) can be used in a cyclone vacuum cleaner (1).
摘要翻译：一种设置有用于从气流分离固体和/或液体颗粒的旋风室（11,79）的分离器装置（3）。旋风室（11,79）具有其中存在出口开口（15）的上壁（49）和基本上旋转对称的侧壁（47,81），在该侧壁中存在入口开口（13）上壁（49）。用于分离的固体和/或液体颗粒的排出口（17,85）存在于远离上壁（49）的旋风室（11,79）的侧面（55,83）处。根据本发明，可旋转的环形离心机组（61,87）在靠近上壁（49）的出口开口（15）周围设置在旋风室（11,79）内，借助于该单元，短路防止在旋风室（11,79）中直接从入口（13）流到出口（15）的流动。因此，分离装置（3）的效率大大提高。在第一实施例中，离心单元（61）包括邻近并平行于上壁（49）定位的可旋转环形盘（65）。在第二实施例中，离心单元（87）包括可旋转的边缘（89），其部分地埋入上壁（49）中的凹部（95）中。分离器装置（3）可用于旋风式真空吸尘器（1）。
