    • A toothbrush is provided having two housing sections (1, 2) which are pivotable relative to one another, of which a first housing section (1) serves as a handle and accommodates a drive unit (4) for driving a drive shaft (5), and of which a second housing section (2) carries a brush-head (3), which is drivable by the drive shaft, which second housing section (2) is pivotable relative to the drive shaft (5) about a pivot (6). To warn the user against an excessive brushing pressure the toothbrush has a spring device with at least one spring (14) which acts between the second housing section (2) and the drive shaft (5), the second housing section (2) being pivotable relative to the first housing section (1) about the pivot (6) against a pressure exerted by the spring (14) during use of the toothbrush, which spring snaps when a given pressure threshold is exceeded and which pivot is disposed in the second housing section and also forms at least a part of a mechanical coupling between the drive shaft and the second housing section.
    • 一种牙刷设置有两个相对于彼此枢转的壳体部分(1,2),其中第一壳体部分(1)用作手柄并且容纳用于驱动驱动轴(5)的驱动单元(4) ,并且其中第二壳体部分(2)承载可由驱动轴驱动的刷头(3),该第二壳体部分(2)可相对于驱动轴(5)围绕枢轴(6)枢转 )。 为了警告用户避免过度的刷牙压力,牙刷具有弹簧装置,其具有至少一个弹簧(14),弹簧(14)作用在第二壳体部分(2)和驱动轴(5)之间,第二壳体部分(2)可枢转 相对于在使用牙刷期间由弹簧(14)施加的压力而围绕枢轴(6)相对于第一壳体部分(1),当超过给定的压力阈值时,该弹簧卡扣,并且哪个枢轴设置在第二壳体 并且还形成驱动轴和第二壳体部分之间的机械联接的至少一部分。

    • A toothbrush comprises two parts (2, 3) which are pivotable relative to one another, of which a first part (2) serves as a handle and of which a second part (3) carries a brush-head (5), a spring (7) being arranged between the parts and having one end (8) fixedly connected to one (2) of the parts and having another end (9) which engages with a wall portion (11) of the second part (3), the second part (3) being pivotable relative to the first part (2) against a pressure exerted by the spring (7) during use of the toothbrush, which spring snaps when a given pressure threshold (P.sub.d) is exceeded, after which the second part (3) is subjected only to a bending load in the absence of a pressure (Q) directed in the longitudinal direction of the spring (7) and exerted by the wall portion (11), and resumes its original position when the pressure has decreased.
    • 牙刷包括相对于彼此可枢转的两个部分(2,3),其中第一部分(2)用作手柄,并且第二部分(3)承载着刷头(5),弹簧 (7)布置在所述部件之间并且具有固定地连接到所述部件的一个(2)的一个端部(8),并且具有与所述第二部分(3)的壁部分(11)接合的另一端部(9) 第二部分(3)相对于第一部分(2)抵抗在使用牙刷期间由弹簧(7)施加的压力可枢转,当超过给定的压力阈值(Pd)时,弹簧卡扣,之后第二部分 (3)仅在没有朝向弹簧(7)的纵向方向施加的压力(Q)的情况下受到弯曲载荷,并被壁部分(11)施加,并且当压力降低时恢复其初始位置 。

    • 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。
