摘要： The invention is directed to an internal combustion engine for a portable handheld work apparatus with an intake pipe or induction elbow being attached to the cylinder. The engine can be a two-stroke engine having an inlet opening in the cylinder for the combustion mixture. A cylinder flange is provided at the inlet opening for connecting the induction elbow for conducting the combustion mixture. The induction elbow is made of rubber-elastic material and fits over the cylinder flange in a form-tight manner and is fixed thereto. The connecting end of the induction elbow is provided with an inner annular shoulder which engages an outer annular slot of the cylinder flange which is adapted with respect to volume and is reliably held by a clamp ring having a fixed diameter. The rubber-elastic material of the connecting end is compressed in the annular slot by the clamp ring thereby seating the induction elbow on the cylinder flange in such a manner that it cannot become disconnected.

摘要： The invention is directed to a motor-driven chain saw wherein a sprocket for a saw chain and a drive wheel for an oil pump are rotatably journalled on the crankshaft. The oil pump pumps oil for lubricating the saw chain and guide bar. The sprocket and the drive wheel are driven via a clutch drum. In this arrangement, a detachable resilient connecting member is provided to connect the drive wheel of the oil pump to the clutch drum at the peripheral wall of the latter. The resilient connecting member protects the drive wheel and the oil pump from excessive wear.

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.
摘要翻译：本发明涉及一种便携式手持电动链锯1的马达单元2和手柄单元9之间的防振装置。防振装置包括一个套筒形弹性基体6，其中一个端部36位于插座20中电机单元2的另一端46和手柄单元9的插座90中。基体的端部（36,46）通过轴向接合插塞（31,41）固定在插座（20,90）中，在末端部分（30,40）中。电动链锯的引导特性不受受损或软化的基体的影响。这是因为止动件31中的至少一个具有联接构件50，其联接插塞（31,41）之间的轴向间隔（z）并且突出到另一个插头41中并且被闩锁，使得其不能与其轴向分离。当基体撕裂时，手柄单元和马达单元之间保持机械连接。

摘要： The invention relates to a portable handheld tool such as a motor chain saw, cutoff machine or the like having a motor arranged in a housing. The motor drives a work tool via a drive pinion. The portable, handheld tool is provided with a handle arrangement for holding and guiding the tool with the handle arangement being decoupled from the motor system by antivibration elements. Soft antivibration elements are required to obtain high isolation; whereas, the antivibration elements have to be as stiff as possible in order to reliably guide and hold the handheld tool. The antivibration elements holding the handle arrangement on the side of the drive pinion are arranged to lie approximately in a common plane. This arrangement makes it possible to use softer antivibration elements without the required stiffness for guiding and holding becoming too low.

摘要： A portable motor chain saw with a safety braking device to protect against kick-back, recoil or centrifugal movements of the saw. The saw includes a handle supported against the motor housing by damping elements, and also includes a locking device which on the one hand is connected with the handle, and on the other hand engages against a hand guard in such a way that it is released under the influence of relative movement, of the motor housing with respect to the handle, caused by a kick-back or centrifugal movement, consequently releasing the hand guard. The locking device has an abutment surface extending transverse to the direction of centrifugal movement, and this abutment surface cooperates with a projection directed against it.

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.
