用于内燃机气缸外壳的缸径及由该缸径和活塞组成的装置
摘要：
本发明涉及一种缸径(10、110)，其具有用于内燃机的气缸外壳的气缸运行表面(14、114)。在所述缸径(10、110)中限定上折返点(OS)和下折返点(US)。在所述缸径(10、110)中上下移动并且具有活塞环(21)和活塞轴(22)的活塞(20)当电动机运转时在折返点处达到几乎为零的速度(V0)，并且所述活塞(20)当电动机运转时在所述上折返点(OS)与所述下折返点(US)之间的区域(15、115)中达到最大速度(Vmax)。本发明的特征在于，在所述区域(15、115)内形成至少两个圆周凹陷(18a、18b；118a、118b、118c)，并且所述凹陷的直径(D2a、D2b、D2c)大于所述区域(15、115)上方的所述缸径(10、110)的直径(D1)并且大于所述区域(15、115)下方的直径(D3)。
摘要（英）：

The invention relates to a cylinder bore (10, 110) with a cylinder running surface (14, 114) for a cylinder housing of an internal combustion engine. An upper reversal point (OS) and a lower reversalpoint (US) are defined in the cylinder bore (10, 110). A piston (20) which is moved up and down in the cylinder bore (10, 110) and has piston rings (21) and a piston shaft (22) reaches a speed (V0) which is almost zero at the reversal points when the motor is being operated, and the piston (20) reaches a maximum speed (Vmax) in a region (15, 115) between the upper reversal point (OS) and the lowerreversal point (US) when the motor is being operated. The invention is characterized in that at least two circumferential depressions (18a, 18b; 118a, 118b, 118c) are formed within the region (15, 115), and the diameter (D2a, D2b, D2c) of the depressions is greater than the diameter (D1) of the cylinder bore (10, 110) above the region (15, 115) and greater than the diameter (D3) below the region(15, 115).
