    • A dry-shaving apparatus comprises a shear-shaving section having a first head member formed by an arcuate flexible shear foil providing a working surface, such shear-shaving section including a plurality of reciprocatingly drivable cutters co-operating with the flexible shear foil. Included is a comb-shaving section having a second head member constructed as a rigid trough-shaped part fixedly and permanently connected to the flexible shear foil and provided with a working surface, such comb-shaving section including a reciprocatingly drivable rigid cutter co-operating with the rigid trough-shaped part. The first head member and the second head member together constitute a head-member unit. A cutter unit co-operates with the head-member unit and includes a reciprocatingly drivable support for supporting and driving the cutters of the respective shaving sections. The working surface of the comb-shaving section adjoins the working surface of the shear-shaving section and projects laterally therefrom, the plane defined by the working surface of the comb-shaving section forming an obtuse angle with the plane tangent to the working surface of the shear-shaving section at the location where the two shaving sections adjoin each other. The rigid cutter of the comb-shaving section is supported by the cutter unit support by means of at least one spring.
    • 干剃刮装置包括剪切剃须部分,其具有由提供工作表面的弓形柔性剪切箔形成的第一头部构件,所述剪切剃须部分包括与柔性剪切箔合作的多个可往复驱动的切割器。 包括的梳子部分具有第二头部构件,该第二头部构件被构造为刚性槽形部分,固定地并永久地连接到柔性剪切箔并设置有工作表面,这种梳理部分包括可往复驱动的刚性切割器 与刚性槽形部分。 第一头部构件和第二头部构件一起构成头部构件单元。 切割器单元与头部构件单元配合,并且包括可往复驱动的支撑件,用于支撑和驱动各个剃须部分的切割器。 梳齿切割部分的工作表面与剪切部分的工作表面相邻并且从侧面突出,由梳齿切割部分的工作表面限定的平面与工作表面的切线面成钝角 在两个剃须部彼此相邻的位置处的剪切部分。 梳形剃须部分的刚性切割器通过至少一个弹簧由切割器单元支撑件支撑。

    • A piston has an upper crown portion with an upper combustion wall against which combustion forces act and a lower crown portion with a pair of pin bosses spaced for receipt of a small end of a connecting rod therebetween. The upper crown portion and the lower crown portion form an outer oil gallery and a central oil gallery in fluid communication with one another. The central oil gallery is formed in part by an annular flange extending radially inwardly from the outer oil gallery and upwardly toward the upper combustion wall to a free edge spaced from the upper combustion wall. The free edge forms an opening about a central axis of the piston and has a non-planar uppermost surface with depressions aligned diametrically opposite one another across the opening to improve the oil flow throughout the central oil gallery.
    • 活塞具有上冠部,其具有燃烧力作用的上燃烧壁和具有一对销凸起的下冠部,其间隔开以容纳连接杆的小端。 上冠部和下冠部形成外部油道和中心油画廊,彼此流体连通。 中央油库部分地由从外油道径向向内延伸的环形凸缘形成,并且朝向上燃烧壁向上延伸到与上燃烧壁间隔开的自由边缘。 自由边缘围绕活塞的中心轴线形成开口,并且具有不平坦的最上表面,其凹陷沿开口对齐地彼此沿径向相对,以改善贯穿中央油画廊的油流。
