摘要： The invention related to a two-stroke internal combustion engine (1 ), comprising a crankcase (2), which has an air intake (3), and at least one cylinder (4), which is connected to the crankcase (2) and which, together with a piston (5) arranged therein, defines a combustion chamber (6). The cylinder (4) has at least one air inlet (7), which via an air duct (8) communicates with the crankcase (2), in which a mixture of air and lubricating oil and fuel, if any, is contained. The air duct (8) is connected to the crankcase (2) via a separator (10) for cleaning of air coming from the crankcase (2) from lubricating oil and fuel, if any. The separator (10) has a centrifugal chamber (11 ), in which the lubricating oil and the fuel, if any, in a circulating motion are thrown outwards to a circumferential wall (12) and thus substantially cleaned air is passed, through a chamber outlet (13), which with respect to said circulating motion is a radially inner outlet, to said air duct (8) to be supplied to the combustion chamber (6) through the air inlet (7).

摘要： The invention relates to a fuel-powered breaker machine (1) which has a cylinder (2, 2.3, 2.4) with two pistons (3, 4) disposed therein. The first of the pistons (3) is adapted to opening and closing at least an inlet aperture (5, 6) on an inlet side (I) in a cylinder shell wall (7), and an outlet aperture (8) on an opposite outlet side (O) in the cylinder shell wall (7), and, when the apertures (5, 6, 8) are closed, to compressing against the second piston (4), which acts as the working piston of the breaker machine (1), an ignitable air/fuel mixture which is admitted via the inlet aperture/apertures (5, 6). The first piston (3) has a crown (11) which is shaped correspondingly to a crown (10) of the second piston (4) and which on said inlet side (I) has a recess (12) which serves, when the first piston (3) is at an upper dead centre position, as a combustion chamber into which a spark plug (16) protrudes via the cylinder shell wall (7) on the inlet side (I), and, when the first piston (3) is at a lower dead centre position, as an inlet chamber into which the inlet aperture/apertures (5, 6) leads/lead.
摘要翻译：本发明涉及一种具有设置在其中的两个活塞（3,4）的气缸（2,2.3,2.4）的燃料供给的断路器机器（1）。活塞（3）中的第一个适于打开和关闭至少一个在气缸壳壁（7）中的入口侧（I）上的入口孔（5,6）和相对的出口孔（8）在气缸壳壁（7）中的出口侧（O），并且当孔（5,6,8）闭合时，压靠作为断路器机器的工作活塞的第二活塞（4） 1），可通过入口孔/孔（5,6）进入的可燃空气/燃料混合物。第一活塞（3）具有相应于第二活塞（4）的表冠（10）成形的冠部（11），并且在所述入口侧（I）上具有凹部（12），所述凹部（12）用于当第一活塞活塞（3）处于上死点位置，作为燃烧室，火花塞（16）经由入口侧（I）上的气缸壳壁（7）突出，并且当第一活塞（3）位于较低的死点位置，作为入口孔，入口孔/孔（5,6）引导/引导入入口室。
