摘要： A recoil starter comprising a housing (1) that is stationary mounted relative to an engine; a moving unit rotatable about a stationary axis (8) of rotation in the housing, the moving unit comprising a line pulley (2) onto which a pulling line (3) is winded, an inner end of the pulling line being anchored near a centre of the line pulley (2) and an outer, free end of which reaches through an aperture formed through a wall of the housing (1); a return spring (4) connected to the line pulley (2), said return spring arranged to be stretched by the line pulley when the line pulley is rotated about said axis (8) in result of pulling the pulling line (3) off from the line pulley, and which is operative upon return to rewind the pulling line onto the line pulley; a carrier (6) driven by said line pulley for rotation about said stationary axis (8); a swinging pawl (5) supported on the carrier (6), said pawl driven by said carrier in rotation to engage a crank shaft of the engine for transferring upon said crank shaft the rotation of said carrier (6), and which pawl returns to a non-engaging position on said carrier when the rotational speed of the crank shaft exceeds the rotational speed of the carrier upon ignition of the engine. The carrier is shiftable from contra-rotation to co-rotation with the line pulley and vice versa, and the carrier carries at least two pawls, each of which is operative in one of said co-rotational and contra-rotational directions.
