Definitions
- the present invention relates to a chain saw with a motor, which is attached to a housing and has an inlet channel, which inlet channel for decoupling vibrations via an elastic Intake hose is connected to a carburetor that is in turn mounted on the housing with the aid of fastening means.
- Such a chainsaw is e.g. known from the document DE-A1-42 34 483.
- the carburetor one by an internal combustion engine (usually one high-speed 2-stroke engine) powered chainsaw has an essential Influence on the operating behavior of the device. vibrations that come from the moving piston of the engine and onto the carburetor act, can lead to an irregular fuel supply, which endangers trouble-free engine operation. This is why it is known for engines that are equipped with a carburetor Connect the carburetor to the engine using an elastic intake pipe and in addition an elastic suspension of the carburetor in the housing to accomplish. Such elastic suspensions can by some Types of elastic members, usually rubber, are provided become. Such elements allow efficient vibration isolation to reach the carburetor. However, it is a disadvantage such a suspension that sufficient for vibration isolation allow elastic elements too large movements of the carburetor.
- An elastic inlet pipe is e.g. from DE-GM 1 762 310 or SE-PS 8 6022 481-7 known.
- the known articulated connection has several disadvantages: On the one hand, such a connection is comparatively complex and complicated to set up because parts are manufactured with articulated holes and the hinge connections are equipped with corresponding hinge bolts Need to become. On the other hand is the assembly and service-related Disassembly is expensive because the hinge pins in the hinge connections assembled and secured or unlocked and dismantled with a lot of effort Need to become. Finally, the articulated connection allows only a limited one Mobility of the carburetor, namely in the direction transverse to Articulation. An agility towards the articulation on the other hand, can only be realized with a lot of effort if the hinge pins be formed elastically.
- a first preferred embodiment of the chain saw according to the invention is characterized in that a recording from the housing an elastic material, in particular an elastic sleeve Rubber, is attached, and that the carburetor with a snap-in part in the Recording or elastic sleeve is releasably engaged.
- the carburetor leaves in this way by simply snapping it into the holder assemble or disassemble by snapping out of the holder.
- the snap-in part is designed as a spherical head. By doing without the snap-in part can be comparatively small on snap-in edges Resistance engage or unlock.
- the ball head also works like a ball joint.
- a pin can also be formed, which is pushed through the sleeve (not shown).
- the sleeve can be made even more generous (eg air chamber ) in order to achieve a special damper characteristic and at the same time to ensure a "fixed” adjustment (fastening).
- Another embodiment of the elastic sleeve leaves one essential more elastic design of the damping element. Due to the very elastic The configuration is the assembly process of the damping element not possible together with the intake flange. That's why it will Damping element separated from the intake flange and in the order of assembly be used beforehand. The intake flange is retrofitted engaged.
- the damping element can by the elipsoid Shape in the direction of the carburetor base reached a very "soft" characteristic become.
- the spring characteristic turn out harder. This can make the entire intake system soft be stored, but still be kept axially secure.
- the engine 101 which has a cylinder 10 with a Inlet channel 11 and an outlet channel 12, and a piston 14 comprises, with its crankcase 13 on the bottom 20 of a housing 102 screwed on.
- the housing 102 at least surrounds the motor 101 partially and is closed at the top by a hood 24.
- Within the Housing 102 is an adjacent by a vertical partition 23 the engine 101 lying suction space 19 separated by the above a (removable) cover 22 is closed, and in which one Carburetor 16, in particular in the form of a membrane gasifier, housed is.
- the carburetor 16 is on the output side by an elastic Intake hose 15 connected to the inlet duct 11 of the engine 101.
- the suction hose 15 passes through an opening in the partition 23 and is snapped there.
- the carburetor 16 goes in on the input side an intake manifold 17 which bends upward into an air filter 18 flows into.
- a spherical head 25 is formed on the underside, which engages in an elastic sleeve 21 made of rubber.
- the elastic In turn, sleeve 21 has lugs or pegs, with which they are in one (or more) opening (s) located in the base 20 are inserted in a snap-in manner or can be inserted.
- the ball head 25 can of course have a differently shaped nose or a cone Undercut can be used in an appropriately shaped Opening in the elastic sleeve or a comparable elastic Recording can be inserted or pushed through.
- the ball head 25 has, however the particular advantage that it is particularly easy to insert and also acts as a ball joint.
- Sleeve (receptacle) 21 mounted in the bottom 20 of the housing 102, then then the intake manifold 17 with the carburetor attached to it 16. Disassembly is carried out in the reverse order. Tool not required for this.
- FIG. 2 shows a further embodiment of an elastic sleeve 26, with an elastic annular damping body 27 with fastening parts 28, 29 formed thereon for fastening to the housing base 20 and on the intake manifold 17.
- the damping body 27 is by choosing the diameter of the ring 27a and the cross section body in terms of the desired suspension damping behavior adjustable.
- the fastening parts 28, 29 can be designed differently.
- the fastening part 28 has one rod-shaped holding arm 30 with an end stop button 31 while the fastening part 29 has a rod-shaped holding arm 32 with a Has locking connection 33.
- the locking head 31 is in a corresponding shaped locking receptacle 34 inserted on the intake manifold 17 while the holding arm 32 in a corresponding (not shown) recess is snapped into the housing base 20.
- FIG 3 shows a further embodiment of a sleeve 26, the Holding arm 34 with the discharge end piece 35 in the housing base 20 is inserted.
- the invention results in a chain saw with an internal combustion engine, with the simple, inexpensive and easy to assemble and service Way of carburetor largely harmful Vibrations is decoupled.
