A chainsaw includes a housing, a guide bar, projecting from the housing, and one or more handles. The guide bar has a main direction of extension defined by its center-line. The housing comprises an outer shell made of plastic, which has at least a first outer groove filled with a contrasting plastic material, wherein the groove at least partly extends straight in a transverse direction that deviates less than 3 degrees from a direction perpendicular to the main direction of extension of the guide bar. This provides an indication that facilitates precise and safe felling of trees.

The present disclosure relates to a starter pulley arrangement for an internal combustion engine. The arrangement comprises a cord drum () configured to house a starting rope wound thereon, a driver () configured to interact with a flywheel () or other part connected to an engine crankshaft, and a torsion spring () connecting the cord drum () to the driver (), such that the cord drum can resiliently urge the engine crankshaft via the driver. The torsion spring () is tensioned in a resting position where the driver does not influence the crankshaft. This provides an improved resistance against wear on the parts of the starter pulley arrangement.

Herein a sealing valve arrangement () for a fluid container is disclosed. The sealing valve arrangement () comprising a valve body (), a flexible sealing valve (), and a supporting element (). The flexible sealing valve () comprises a sealing surface () and is situated in the second longitudinal portion () between an intermediate surface () and the supporting element (). A centrally arranged recess () of the flexible sealing valve () forms a blind hole and the sealing surface () abuts against the intermediate surface (), such that the flexible sealing valve () enables a fluid flow thought the through hole () only in a direction from the first longitudinal portion () to the second longitudinal portion () and the channel (). Further a fuel tank for a hand-held power tool comprising a sealing valve arrangement is disclosed.

The present disclosure refers to a crankshaft bearing arrangement for an internal combustion engine. The bearing arrangement comprises: a bearing arranged at a crankshaft of an internal combustion engine; a bearing seat for housing the bearing; and a sealing arrangement for sealing against the crankshaft and the bearing seat. The at least one part of the bearing seat has a reinforcement arranged in the bearing seat, and a surface of the at least one part of the bearing seat, which surface bears against the bearing, is made from a plastic material.

Crankshaft bearing arrangement of a combustion engine

A portable handheld power tool (), such as a chain saw or a power drill, having a receiving device () arranged on a body portion () of the power tool (). The receiving device () is arranged for connecting/disconnecting to the portable handheld power tool () either a flexible elongated member, such as a rope, or a fastening device secured to the elongated member or to an operator of the portable handheld power tool (). The receiving device () has a receiving portion () for receiving and leading the flexible elongated member therethrough. The receiving portion () extends substantially in a plane (P). Furthermore, the receiving device () has an attachment portion () which is arranged to connect the receiving device () to a body portion () of the portable handheld power tool () by means of a pivot assembly (). The pivot assembly () defines a pivot axis (PA), permitting the receiving portion () to move between a resting position, wherein the plane of the receiving portion () is essentially parallel to the pivot axis (PA), and an operating position. In the operating position, the receiving portion () is movable about the pivot axis (PA), and the plane (P) of the receiving portion is essentially perpendicular to the pivot axis (PA).

Portable hand-held power tool

A handle for a hand held engine powered tool may include at least one lever or button for controlling the tool. The handle is made of at least two handle sections joined together. The lever or button for controlling the tool is however only secured in one of the handle sections in order to reduce the required grade of precision between the handle sections without affecting the performance of the lever or button.

The claimed invention relates to an engine powered portable tool comprising a working tool placed on a working tool carrier clamped to a tool casing (). In order to increase the strength in the section where the working tool carrier is clamped to the tool casing () is the working tool carrier clamped to a protruding part () of the crankcase () provided with a component () embedded in the crankcase () wall when the crankcase () is casted. The component () is made of a material with higher E-module than the material in the rest of the crankcase ().
