往复活塞式内燃机和用于往复活塞式内燃机的往复活塞
摘要：
本发明涉及往复活塞式内燃机和用于往复活塞式内燃机的往复活塞，具体而言涉及带有至少一个气缸(42)和至少一个往复活塞(10)的往复活塞式内燃机，其中，往复活塞(10)在往复活塞式内燃机(12)的运行期间在轴向上沿着气缸轴线(Z)往复运动，其中，往复活塞(10)具有带有活塞顶(16)和在活塞顶(16)的背侧构造的活塞下侧(18)的基体(14)，且其中，往复活塞(10)经由活塞销与连杆相连接，其中，设置有至少一个用于产生环形流体流(38)的器件，其中，环形流体流(52)环状地围绕活塞销延伸且流经在活塞下侧(18)与活塞销之间的区域。本发明同样涉及用于往复活塞式内燃机(12)的往复活塞(10)。
摘要（英）：

The invention relates to a reciprocating piston internal combustion engine and a reciprocating piston for the reciprocating piston internal combustion engine. The invention relates in particular to areciprocating piston internal combustion engine with at least one cylinder (42) and at least one reciprocating piston (10), wherein the reciprocating piston (10) reciprocates in the axial direction along a cylinder axis (Z) during operation of the reciprocating piston internal combustion engine (12), wherein the reciprocating piston (10) has a main body (14) with a piston crown (16) and a piston underside (18) formed on the rear side of the piston crown (16), wherein the reciprocating piston (10) is connected to the connecting rod via a piston pin, wherein at least one means for generating anannular fluid flow (38) is provided, and wherein the annular fluid flow (52) extends annularly around the piston pin and flows through a region between the piston underside (18) and the piston pin. The invention also relates to a reciprocating piston (10) for the reciprocating piston internal combustion engine (12).
