摘要： A four stroke engine (100) having a mechanical breather system (135) includes a crankshaft (110) supported by at least one bearing (120), a rotating member (140) coupled to the crankshaft (110). The rotating member (140) can have at least one inlet channel in fluid communication between an outer perimeter of the rotating member (140) and an inner region of the rotating member (140). A breather housing (155) having an air receiving chamber (150) formed therein is positioned adjacent to a portion of the at least one inlet channel (310) of the rotating member (140). A passage (165) formed through a wall (153) is in fluid communication with the air receiving chamber (150) and an exterior of the breather housing (155).

摘要： A four stroke engine (100) having a mechanical breather system (135) includes a crankshaft (110) supported by at least one bearing (120), a rotating member (140) coupled to the crankshaft (110), a breather bearing (145) positioned adjacent to the at least one rotating member (140), an air receiving chamber (150)positioned on the breather bearing (145) and opposite from the rotating member (140), and a passage (165) through a wall (155) of the air receiving chamber (150). The rotating member (140) can have at least one inlet channel in fluid communication between an outer perimeter of the rotating member (140) and an inner region of the rotating member (140). The breather bearing (145) can have an inner race and an outer race. The passage (165) is in fluid communication with an interior of the air receiving chamber (150) and an exterior of the air receiving chamber (150).

摘要： 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 impeller 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.
