摘要： This invention relates to a flexible intake system for a crankcase scavenged two-stroke internal combustion engine (10) having an additional air supply to its transfer ducts. The intake system comprises a flexible intake duct (22) connecting a fuel supply unit (21) e.g. a carburetor with an engine cylinder (11) and at least one flexible air duct (40) connecting a valve housing (42) for additional air with the engine cylinder. The end portion of the flexible intake duct (22) and at least one air duct (40) is secured to the cylinder by means of a baffle (23) made of a stiffer material than the ducts (22, 40) themselves.

摘要： A portable working machine comprising a tool unit (1) with a circular, disc-shaped tool (3), which can be rotated about an axis of rotation (4), which is horizontal in the normal upraised position of the machine, and a machine unit (2), which includes at least a filter system (10), which is at least partly accommodated in a top part of the machine unit, an internal combustion engine (11) with an engine cylinder (13) with bore (12) having a centre line (30), a crankshaft (14) and a crankcase (15), an assembly (16) comprising members for supplying air and fuel to the engine, a fuel tank (17), a muffler (18), handles (19,20), controls (21,22), and preferably supports (23, 24) on the underside of the machine unit for allowing upright positioning of the machine on a flat ground, and a power transmission between the machine unit and the tool unit. Especially the cylinder bore (12) is inclined forwards in a direction towards the tool unit, such that the centre line (30) of the cylinder bore forms a tilt angle (α) larger than zero, in said direction, to a perpendicular to any or both of the following lines: a) a base line (33) , which is a line coinciding with a horizontal surface on which the machine is resting in an upright position, when said supports on the underside of the machine unit contact said surface, and b) a tangential line (33’) extending from a peripheral point of the tool, on the lower part of the tool when the machine has an upright position, to the bottom side of a rear support (24) of the machine unit.

摘要： A cover (30) for concealing one or more components (20) of a power tool (10) presented herein. The cover (30) can include a through recess (52) between an inner surface (702) and an outer surface (708). The through-recess (52) being arranged for receiving a threaded member (80) protruding from the tool (10) and extending between an inner opening (704) at the inner surface (702) and an outer opening (706) at the outer surface (708). A threaded nut (60) for engaging the threaded member (80) for tightening the cover (30) to the tool (10) can be included. Additionally, the threaded nut (60) can be attached to the cover (30). The nut (60) can include a radially protruding portion (70) with a larger radius than the inner opening (704) and outer opening (706). The cover (30) can have opposing first and second shoulder portions (712, 714) surrounding the inner opening (704) and outer opening (706).
摘要翻译：盖（30）用于隐藏本文所呈现的动力工具（10）的一个或多个部件（20）。盖（30）可以包括在内表面（702）和外表面（708）之间的通孔（52）。通孔（52）布置成用于接收从工具（10）突出并且在内表面（702）处的内开口（704）和外表面（702）处的外开口（706）之间延伸的螺纹构件表面（708）。可以包括用于接合螺纹构件（80）以将盖（30）拧紧到工具（10）的螺纹螺母（60）。另外，螺母（60）可以连接到盖子（30）上。螺母（60）可以包括具有比内开口（704）和外开口（706）更大半径的径向突出部分（70）。盖（30）可具有围绕内开口（704）和外开口（706）的相对的第一和第二肩部（712,714）。

摘要： The present invention relates to a portable power tool (1) arranged for driving a rotatable cutting tool (2). The power tool (1) comprises a motor (5) and a transmission part (4) that is arranged to transfer power from the motor (5) to a tool holder (10), and comprises a first arm part (11; 11′) and a second arm part (12; 12′). The first arm part (11; 11′) comprises a first belt pulley (13) and the second arm part comprises a second belt pulley (14), the arm parts (11, 12; 11′, 12′) being slidably connected to each other. The belt pulleys (13, 14) are spaced apart by a certain distance (d-i, d2). The transmission part (4) further comprises a tensioning device (20) with a rod (21), a pre-tensioned resilient device (22), a linkage arrangement (25) and a rotatable part (26). The rotatable part (26) is rotatable between a first, released, state where the belt pulleys (13, 14) are spaced apart by a first distance (d-i), and a second, tightened, state where the belt pulleys (13,14) are spaced apart by a second distance (d2) that exceeds the first distance (d-i), the resilient device (22) being more compressed in the second state than in the first state.
