Abstract: The invention relates to an electromagnetic valve having a valve housing (2) and a valve opening (29) with a valve seat (8) and an electric drive coil (3) and a magnetic yoke (11) and a longitudinal centre axis (14). The magnetic yoke (11) is assigned a metallic plate armature (5) which is mounted movably and has an armature disc (48). The armature disc (48) lies sealingly with a sealing surface (9) against the valve seat (8) in a first switching position of the valve, and opens the valve seat (8) in a second switching position of the valve. According to the invention, the valve seat (8) is configured on a valve component (18), wherein the valve component (18) has at least one valve opening (29) which lies at a radial spacing (r) from the longitudinal centre axis (14). The valve seat (8) of the valve opening (29), which valve seat (8) corresponds with direct body contact with the sealing surface (9) of the armature disc (48) of the plate armature (7), consists of metal.

Abstract: The invention relates to a handheld work apparatus having a handle. A throttle trigger and a throttle trigger lock are arranged on the handle. An operating-mode selector having an off position, an operating position and a starting position is provided. The selector, trigger lock and the trigger are pivotally mounted. A first latching element is provided on the selector and a second latching element is provided on the trigger element, which coact in the starting position of the selector and the starting position of the trigger and hold the trigger in its starting position. To ensure that the starting position of the selector can only be engaged when the trigger is actuated, the second latching element lies outside of the pivot path of the first latching element in the non-actuated position of the trigger.

Abstract: A manually guided implement having a tool driven by an internal combustion engine, which draws combustion air in via an air filter disposed on an air filter base. The air filter is secured to the implement via a releasable securement device that includes a first securement element, and a second securement element that cooperates with the first securement element. The securement elements can be released from one another, or connected to one another, by means of a rotational movement about an axis of rotation. To achieve easy handling of the air filter, the first securement element is fixedly connected to the air filter.

Abstract: An internal combustion engine having an intake channel for supply of fuel and combustion air, and divided over a portion of its length into a mixture channel, and into a supply channel for supply of largely fuel-free air. A simple manufacture of the engine and a simple construction are achieved if a portion of the intake channel is guided in an elastic intake adapter, whereby the intake adapter has a partition that extends over at least a portion of the length of the intake adapter and divides the intake channel into a mixture channel and a supply channel.

Abstract: A portable handheld work apparatus has a housing (2) having at least two housing parts. At least one spring clamp (6, 26, 36, 46, 56) is provided for the releasable attachment of the one housing part to the other housing part. The spring clamp (6, 26, 36, 46, 56) is provided to clamp the two housing parts. A wear protector (8) is effective between the two housing parts in the clamping direction (9). A simple configuration and few individual parts are achieved when the spring clamps (6, 26, 36, 46, 56) have the wear protector (8).
