A suction apparatus includes a suction apparatus housing, including a filter for cleaning a suction flow, wherein the suction apparatus housing has at least one filter fastening element for securing the filter to the suction apparatus housing, and including a filter cleaning device for mechanically cleaning the filter. The filter, the filter fastening element and the filter cleaning device are arranged within the suction apparatus housing. The filter cleaning device includes an actuation device and a hammer device. The actuation device and the hammer device interact such that the hammer device can be actuated by using the actuation device and, when actuated, the hammer device applies at least one pulse to the filter securing element.

Suction apparatus having a filter cleaning device

A suction apparatus includes a housing, at least one cyclone chamber, a collection container configured to as to be releasably connectable to the housing, and having a filter element. The suction apparatus further includes at least one positioning device within the cyclone chamber and configured for positioning at least one collection element within the cyclone chamber.

Suction apparatus

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

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.

Handheld work apparatus

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.

Manually guided implement

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.

Internal combustion engine

A portable handheld work apparatus includes a drive motor configured as an internal combustion engine (). The work apparatus includes an air filter case () arranged in the intake channel of the engine (). The work apparatus further includes a cover () and a locking device () for releasably holding the cover (). An actuating element () of the locking device () is configured as a slider () which is guided so that it is essentially linearly movable.

Portable handheld work apparatus

A portable handheld work apparatus such as a motor-driven chain saw () includes a housing () wherein an internal combustion engine () and a carburetor () are mounted. A throttle lever () is provided which is pivotally journalled on a handle (). The handle () is connected to the housing () via at least one antivibration element (). A vibration gap () is configured between the handle () and the housing (). A transmitting unit () is provided for transmitting the pivot movement of the throttle lever () to the carburetor (). The transmitting unit includes a rigid transmitting element () which bridges the vibration gap (). A simple configuration and a substantial decoupling of the relative movement between the housing () and the handle () from the actuating movement of the carburetor is achieved in that the transmitting element () is rotatably journalled and the pivot movement of the throttle lever () is transmitted as a rotation about a rotational axis () lying transverse to the vibration gap ().
