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 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 braking device, for stopping the saw chain during recoil, and with a release, for the braking device, which in the release position is operatively connected with a locking mechanism of the braking device. The release is an inertial mass which is freely movable along an acceleration path, with the kinetic energy of the inertial mass in the release position being greater than the resistance force of the locking mechanism. The release is held in the ready position by at least one holder, preferably a spring which extends between the saw housing and the release.

摘要： The invention relates to internal combustion engines and especially to two-stroke engines for portable handheld work tools such as motor-driven chain saws or the like. Material made of light metal alloys is used in two-stroke engines for portable handheld tools in order to save weight. Thus, the crankshaft bearing is made of steel while the bearing covers holding the bearing are made of a magnesium alloy. Heating causes the bearing cover to expand by an amount greater than the crankshaft bearing whereby the press fit of the crankshaft bearing can become endangered and, in an extreme case, a clearance can develop between the crankshaft bearing and the bearing cover. According to the invention, the press fit between the crankshaft bearing and the bearing cover is maintained by placing a plastic annular segment therebetween having a thermal expansion coefficient so selected that it compensates for the different thermal expansions of the bearing cover and the bearing.
摘要翻译：本发明涉及内燃机，尤其涉及用于诸如电动链锯等的便携式手持式工作工具的二冲程发动机。由轻金属合金制成的材料用于便携式手持工具的二冲程发动机，以节省重量。因此，曲轴轴承由钢制成，而保持轴承的轴承盖由镁合金制成。加热使得轴承盖膨胀的量大于曲轴轴承，由此曲轴轴承的压配可能变得濒危，并且在极端情况下，曲轴轴承和轴承盖之间可以产生间隙。根据本发明，曲轴轴承和轴承盖之间的压配合通过在其间设置具有如此选择的热膨胀系数的塑料环形部分来维持，以补偿轴承盖和轴承的不同热膨胀。

摘要： The invention is directed to an air-intake arrangement for a two-stroke engine for use in hand-guided, engine-driven apparatus such as motor-driven chain saws. The air-intake arrangement includes an air filter and a baffle wall for guiding fuel particles that are buffeted back out of the air induction channel by the engine. The baffle wall has a curvature to define a deflector to redirect the fuel particles in a largely gaseous state towards the carburetor. The arrangement provides an optimum air-fuel mixture which is not overrich and a trouble-free operation of the engine.

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.
