Definitions

  • the invention relates to a carburetor of the type specified in the preamble of claim 1.
  • the invention has for its object to provide a carburetor of the generic type, which is simple and has a small size.
  • the coupling element has a hook-shaped portion which is elastic.
  • the hook-shaped design high elasticity is achieved.
  • the hook-shaped portion also forms a favorable contour for a locking of the two coupling elements.
  • the elastic coupling element is at least partially, in particular completely made of plastic.
  • Advantageous is the plastic POM.
  • the other coupling element is advantageously dimensionally stable in the usual forces during operation. The elastic coupling element is thereby deformed by the dimensionally stable coupling element. Because one of the coupling elements is dimensionally stable, one or more detent positions can be defined comparatively precisely.
  • the first, connected to the throttle shaft coupling element is elastic and the second, connected to the choke shaft coupling element is dimensionally stable.
  • the coupling elements are in particular designed as levers.
  • the operator first gas, so must open the throttle element and then insert the choke, so the choke can pivot.
  • the first coupling element has a locking contour which cooperates with a locking portion of the second coupling element and the second coupling element blocks when the throttle element is closed and prevents rotation of the choke shaft in the opening direction.
  • a simple structure results when the hook-shaped portion forms the locking contour.
  • the coupling elements are usually subject to manufacturing tolerances.
  • a device for compensating the manufacturing tolerances is provided.
  • an intermediate lever is rotatably mounted on the choke shaft, and that the second coupling element is rotatably mounted on the choke shaft and is coupled to the intermediate lever via a coupling device.
  • the coupling device allows for a limited mobility of the second coupling element relative to the intermediate lever in at least one direction. As a result, it can be ensured, on the one hand, that a detent position between the two coupling elements is always achieved, even with unfavorable manufacturing tolerances. On the other hand, it can be ensured that the choke element is safely closed when the choke is engaged.
  • the coupling device limits the mobility of the second coupling element relative to the intermediate lever in both directions of rotation.
  • the second coupling element takes the intermediate lever with when the choke is inserted.
  • counter-rotation direction entrainment of the second coupling element via the intermediate lever is desirable in order to allow iced-away choke element or the like.
  • a simple structural design results when the coupling device is formed by a pin which projects into an opening, wherein the extent of the pin in the circumferential direction of the choke shaft is smaller than that of the opening. The game between pin and opening in the circumferential direction ensures the limited mobility of the second coupling element relative to the intermediate lever.
  • the pin is formed on the second coupling element and the opening on the intermediate lever.
  • a coupling spring is arranged in the effective direction between the second coupling element and the intermediate lever.
  • the choke element can be safely closed, in the context of the limited mobility that allows the coupling device, regardless of existing manufacturing tolerances.
  • the coupling spring secures the intermediate lever in the axial direction. As a result, an additional securing element can be omitted.
  • the intermediate lever and the second coupling element made of a dimensionally stable material, in particular made of metal or of a dimensionally stable plastic.
  • Dimensionally stable plastic as the material for the intermediate lever and / or the second coupling element is particularly advantageous in order to achieve favorable sliding pairings with other components such as, for example, a selector shaft.
  • the first coupling element is fixed to the throttle shaft via a fastening screw.
  • the fastening screw extends advantageously in an approximately radial direction to the axis of rotation of the throttle shaft.
  • Fig. 1 shows as an exemplary embodiment of a hand-held implement a power saw 1.
  • carburetor can also be used in other internal combustion engine driven hand-held implements such as cutters, brushcutters or the like.
  • the power saw 1 has a housing 2, on which a rear handle 3 and a handle tube 4 are arranged via anti-vibration elements, not shown.
  • a guide rail 5 from, on which a saw chain 6 is arranged.
  • the saw chain 6 is driven in rotation by a combustion engine 8 arranged in the housing 2.
  • the internal combustion engine 8 is advantageously a two-stroke engine, in particular a two-stroke engine operating with a scavenging charge.
  • a hand guard 7 is arranged on the housing 2.
  • the internal combustion engine 8 is connected to a carburetor 9 via an intake passage 10.
  • the internal combustion engine 8 is designed as a two-stroke engine operating with a rinsing template.
  • the intake passage 10 is divided by a partition wall 26 into an air passage 27 and a mixture passage 28.
  • a mode selector 11 is pivotally mounted on the housing 2 in the direction of arrow 12.
  • the throttle lever 13 and a throttle lock 14 are also arranged.
  • the mode selector 11 has a plurality of positions, namely a stop position, an operating position and at least one starting position.

  • the throttle lever 23 can pivot freely from choke lever 24 and intermediate lever 25.
  • the mode selector 11 was pivoted from the operating position to the starting position, after the throttle lever 13 is pressed and thereby the throttle lever 23 in the in Fig. 5 shown position was brought.
  • the choke valve 17 is completely closed.
  • the throttle valve 19 is in a middle position and closes the intake passage 10 partially. In this position, the throttle lever 23 and the choke lever 24 are locked together in a locking position 42.

As the figures show, open throttle 19 and choke 17 in the same direction, namely in the figures in a clockwise direction.
  • FIGS. 7 to 9 show the blocking position of the throttle lever 23 and choke lever 24.
  • the choke lever 24 has a locking portion 38 which is formed as the hook-shaped portion 72 facing the short leg 37 engages behind nose and hooks into the hook-shaped portion 72 and thus prevents further opening of the choke 17.

After deformation, the throttle lever 23 thus returns to its original shape. If the choke lever 24 is pivoted in the direction of the arrow 30, then the detent recess 36 presses against the short leg 37 of the throttle lever 23 and deforms the hook-shaped section 72 in the direction of the arrow 39, as in FIG Fig. 10 indicated by the dot-dash line.

  • the two levers are connected to each other via a coupling device 31, which allows a limited relative movement between the two levers.
