摘要： A handheld work apparatus has a drive motor (8) that is held in a motor housing (2). At least one handle (4) is provided, with a vibration gap (12) being formed between the handle (4) and the motor housing (2). The vibration gap (12) permits a relative movement between handle (4) and motor housing (2). The handle (4) is connected to the motor housing (2) via at least one anti-vibration device (13, 14, 15, 16, 31, 49, 50, 63) that bridges the vibration gap (12). The anti-vibration device (15, 16, 31, 49, 50, 63) has a longitudinal center axis (23, 24). The anti-vibration device (15, 16, 31, 49, 50, 63) bridges the vibration gap (12) via at least one tension element. The anti-vibration device (15, 16, 31, 49, 50, 63) also has a spring (17, 32, 33, 51, 55, 72, 73) arranged functionally in series with the tension element.

摘要： A handheld work apparatus has a housing (2) wherein an internal combustion engine (10) and a fuel-metering unit for the engine (10) are mounted. A throttle lever (6) is provided which is pivotally journalled on a handle (3). The handle (3) is connected to the housing (2) via at least one antivibration element (33). A vibration gap (9) is formed between the handle (3) and the housing (2). A transmitting unit (13) is provided for transmitting the pivot movement of the throttle lever (6) to the fuel-metering unit. The transmitting unit (13) includes a rigid transmitting element (17, 77) which bridges the vibration gap (9). The transmitting element (17, 77) is rotatably journalled on at least one bearing (18, 19, 59) and transmits the pivot movement of the throttle lever (6) as a rotation about a rotational axis (22) lying transversely to the vibration gap (9). A first bearing (19, 59) of the transmitting element (17, 77) is located on the fuel-metering unit.

摘要： In an internal combustion engine (2) of a portable handheld work apparatus, the cylinder (3) is provided with cooling ribs (4, 4′). A cooling airflow is generated by the fan wheel (13) and is guided over the cooling ribs. A carburetor (9) is temperaturized as required by the heated cooling air. A control of the cooling airflow to the carburetor (9) takes place in that an opening (11), which passes the heated cooling air, is selectively closed or opened via a closure element (12). In order to obtain improved cooling of the cylinder during summer operation as well as during winter operation, the closure element (12) is provided with at least one air guide wall which extends essentially transversely to the cooling airflow and causes this cooling air to be partially backed up and deflected.

摘要： A carburetor (1) for an internal combustion engine has an intake channel section (3) wherein a throttle element and a choke element are supported to pivot about respective rotational axes (34, 35). The carburetor (1) has a starter unit which has an operating position, an off position and at least one start position. In the start position, the starter unit fixes defined positions of the throttle element and the choke element. A simple manipulability and a multifaceted operational use of the carburetor (1) are achieved when the starter unit includes an actuating lever (29, 69) and an intermediate lever (18, 68) having respective rotational axes (28, 37) which are at a distance (c) to each other at least at the elevation of the intermediate lever (18, 68) and when the actuating lever (29, 69) acts on the throttle element via the intermediate lever (18, 68).
