Abstract

DC60 (11/05/60) The actuator switches the position of the main part of the switching pin between first and second position by adding pressure to the main parts of the commutator pin in the axial direction of the camshaft At least the main part of the pin The commutator is overlapped with the cover cover when viewed from the axial direction of the camshaft. The actuator is arranged on the opposite side of the cam chain chamber relative to the camshaft in Axial direction of the camshaft The actuators are arranged outside the engine. The actuators are positioned more towards the cover than the tip of the cylinder head.

Disclaimer (all) which will not appear on the advertisement page: Revised 11/5/2017 1. The engine (1), which is a single cylinder engine, consists of a cylinder body (5), a cylinder head (6), as well as a combustion chamber (11) and a cam chain chambers (16). The direction perpendicular to the cylinder axis (Ax1) of the cylinder body (5) for the combustion chamber (11), where the cylinder head (6) is attached to the cylinder body (5), the cover (7), as well as the tip (701) is Aligned facing the end (601) of the cylinder head (6), where the cover (7) is attached to the cylinder head (6), the cam chain (15) is arranged in the cam chain chamber (16) camshaft. (14) is linked to the cam chain (15), where the camshaft (14) is supported by the cylinder head (6) the bell shaft (33) is supported by the cylinder head (6), where the bell shaft (33) is parallel to the camshaft. (14) The first valve (36) is supported by the bell shaft (33) The second bell (37) is supported by the bell shaft (33) where the second bell (37) is arranged in line with the valve bell. At one (36) in the axial direction of the cam (14), the main part of the commutator pin (35) is configured to move in the direction. Along the axis of the camshaft (14), where the main part of the commutator pin (35) is configured to move between the first position where the first valve bell (36) and the second valve bell (37) are linked, and The second position where the first valve (36) and the second bell (37) are not linked. Which main parts of The commutator pin (35) is configured so that the first valve bell (36) and the second valve bell (37) are positioned at the first position, and the actuator (39) is configured so that the position of the main parts is switched. of The commutator pin (35) between the first and the second position by increasing the pressure. To the main part of the commutator pin (35) in the axial direction of the thumb cam (14), where at least the main part of the commutator pin (35) overlaps with the cover (7) as viewed from The axial direction of the camshaft (14), the actuator (39) is arranged on the opposite side with the cam chain chamber (16) for the camshaft (14) the axial directional filament of the camshaft (14) and the actuator. (39) is arranged on the outside of the engine (1), whose special feature is the actuator (39), is positioned more towards the bonnet side than the tip (601) of the cylinder head (6).
