Carburetor having a coupling element and a coupling element for connecting an actuating element to an adjusting element

Abstract

A carburetor (1) has an adjusting element which is mounted in an intake channel (3). An actuating element (19) is provided for actuating the adjusting element. The carburetor (1) has a coupling element for connecting the actuating element (19) to the adjusting element. The coupling element has a receptacle (23, 43) for the actuating element (19). In the receptacle (23, 43), the actuating element (19) is held moveable in its longitudinal direction opposite to the actuating direction (35). The coupling element has an access opening which makes the receptacle (23, 43) accessible at the periphery. An unintended unhooking of the actuating element (19) out of the coupling element is avoided when the access opening has an access slot (26) which extends at an angle to the receptacle (23) up to the receptacle (23). The access slot (26) is connected to the receptacle (23) via at least one connecting slot (31, 32).

Claims

1. A carburetor comprising: an intake channel;an adjusting element mounted in said intake channel;an actuating element for actuating said adjusting element when said actuating element is activated in a predetermined actuating direction;said actuating element defining a longitudinal direction;a coupling element for connecting said actuating element to said adjusting element;said coupling element having a receptacle for receiving said actuating element therein so as to moveably hold said actuating element in said longitudinal direction opposite said actuating direction;said coupling element having an access slot for facilitating access to said receptacle;said access slot extending at an angle to said receptacle; and,said coupling element further having at least one connecting slot for connecting said access slot to said receptacle.

2. The carburetor of claim 1, wherein said connecting slot extends in a radial direction to said receptacle and at an angle to said access slot.

3. The carburetor of claim 2, wherein said receptacle has a side lying opposite to said connecting slot; and, said receptacle is configured to be closed at said side lying opposite to said connecting slot.

4. The carburetor of claim 3, wherein said connecting slot is a first connecting slot and wherein said coupling element has a second connecting slot.

5. The carburetor of claim 1, wherein said actuating element has a stop for limiting the movement of said actuating element in said receptacle in said actuating direction.

6. The carburetor of claim 1, wherein said actuating element has a region having an enlarged diameter (d) with said region being disposed in said receptacle; and, said access slot has a minimal width (a, c) less than said enlarged diameter (d) of said actuating element.

7. The carburetor of claim 1, wherein said coupling element defines a rotational axis perpendicular to said actuating direction and said coupling element is rotatable about said rotational axis relative to said adjusting element.

8. A carburetor comprising: an intake channel;an adjusting element mounted in said intake channel;an actuating element for actuating said adjusting element when said actuating element is activated in a predetermined actuating direction;said actuating element defining a longitudinal direction;a coupling element for connecting said actuating element to said adjusting element;said coupling element having a receptacle for receiving said actuating element therein so as to moveably hold said actuating element in said longitudinal direction opposite said actuating direction;said coupling element having an access opening for facilitating access to said receptacle;said actuating element being guided away from said carburetor in a first direction which lies at an angle to said actuating direction on said coupling element; and,said access opening, when viewed in said actuating direction, and said first direction conjointly defining an angle (α) of less than 450°.

9. The carburetor of claim 8, wherein said angle (a) is less than 30°.

10. The carburetor of claim 8, wherein said receptacle has a side lying opposite said access opening; and, said receptacle is configured to be closed at said side lying opposite said access opening.

11. The carburetor of claim 8, wherein said access opening is configured as an access slot which extends parallel to said actuating direction of said actuating element.

12. The carburetor of claim 11, wherein said coupling element is a cylindrical base body in which said receptacle is formed; and, said access slot extends from the periphery of said base body to said receptacle.

13. The carburetor of claim 8, wherein said actuating element has a stop for limiting the movement of said actuating element in said receptacle in said actuating direction.

14. The carburetor of claim 8, wherein said actuating element has a region having an enlarged diameter (d) with said region being disposed in said receptacle; and, said access slot has a minimal width (a, c) less than said enlarged diameter (d) of said actuating element.

15. The carburetor of claim 8, wherein said coupling element defines a rotational axis perpendicular to said actuating direction and said coupling element is rotatable about said rotational axis relative to said adjusting element.

16. A coupling element for connecting an actuating element to an adjusting element, said coupling element comprising: a base body having a receptacle formed therein for accommodating said actuating element;said base body having an access opening formed therein via which said receptacle is accessible from the periphery of said base body;said access opening including an access slot which extends at an angle to said receptacle;at least one connecting slot; and,said access slot being connected to said receptacle via said connecting slot.

17. The coupling element of claim 16, wherein said connecting slot extends in a radial direction to said receptacle and at an angle to said access slot.
