    摘要： The invention relates to an antivibration device between a motor unit 2 and a handle unit 9 of a portable handheld motor-driven chain saw 1. The antivibration device includes a sleeve-shaped elastic base body 6 having one of its ends 36 in a receptacle 20 of the motor unit 2 and the other end 46 in a receptacle 90 of the handle unit 9. The ends (36, 46) of the base body are fixed in the receptacles (20, 90) by axially engaging plugs (31, 41) in the end sections (30, 40). The guiding characteristics of the motor-driven chain saw are not affected by base bodies which become damaged or soft. This is so because at least one of the stops 31 has a coupling member 50 which bridges an axial spacing (z) between the plugs (31, 41) and projects into the other plug 41 and is latched so that it cannot be axially separated therefrom. A mechanical connection remains between the handle unit and the motor unit when the base body tears off.

    摘要： An anti-vibration element has a tubular elastic base body with a first and a second end for connecting parts in a vibration-damping manner. A dumbbell-shaped bolt has a connecting element and a first and a second clamping element connected to opposite ends of the connecting element. The dumbbell-shaped bolt is inserted into the base body such that the dumbbell-shaped bolt has limited axial displacement. The connecting element can be made of a substantially rigid or a substantially elastic material. In a preferred embodiment, the first clamping element is axially fixed relative to the longitudinal axis of the base body and the second clamping element is axially displaceable relative to the longitudinal axis of the base body.

    摘要： The invention relates to a portable handheld work apparatus such as a motor-driven chain saw. The apparatus includes an internal combustion engine as a drive motor for a work tool. The engine is mounted in a housing. The engine draws combustion air from the clean compartment of a filter case via an intake channel. The clean compartment is partitioned from a dirt compartment of the filter case by an air filter. The filter case itself is closed by a hood. The cover is configured as a hood of the motor housing and is pivoted about a pivot axis which is held to the motor housing by at least one bearing. In this way, the air-filter case can be cleaned in a simple manner without a tool. When the hood is flipped open, the filter case is freely accessible so that the necessary maintenance of the air filter or cleaning of the filter case is possible.
