Abstract: Hand-held blower devices with vacuum function are provided. In this regard, a representative device includes: a housing defining an interior, an intake and an exhaust; an impeder mounted within the interior and being operative to rotate such that air is drawn into the interior through the intake and expelled from the interior through the exhaust; a locking mechanism mounted to the housing, the locking mechanism being movable between an unlocked position and a locked position; and a vacuum tube assembly having an inlet end and an outlet end and defining an air passageway between the inlet end and the outlet end, the outlet end being operative to engage the intake of the housing for the vacuum mode of operation; the locking mechanism being operative to interface with the vacuum tube assembly to retain the outlet end of the vacuum tube assembly in engagement with the intake of the housing for the vacuum mode of operation.

Abstract: A mechanical breather system for a four-stroke engine includes a rotating member. The rotating member can have at least one inlet channel in fluid communication between an outer perimeter of the rotating member and an inner region of the rotating member. A breather housing having an air receiving chamber formed therein is fluidly coupled to the at least one inlet channel of the rotating member. A passage can be formed through a wall of the breather housing is in fluid communication with the air receiving chamber and an exterior of the breather housing.

Abstract: A rope-pull starting device for an internal combustion engine including a hub, rope pulley, rope and torsion damper spring. The hub configured to drivingly engage an engine when the hub is rotated in a first direction. The rope pulley interconnects with the hub by a torsion damper spring. The torsion damper spring coupled at a first end to the hub and at a second end to the rope pulley, wherein the torsion damper spring is coiled from the first end connected to the hub, toward the rope pulley, in a second direction opposite to the first direction, and whereby the rope pulley is rotated in the first direction when the rope is unwound therefrom and the torsion damper spring responsively urges the hub to rotate in the first direction.
