    摘要: A portable handheld suction/blower apparatus includes a motor-driven blower (1) and at least one air guide tube (3) connected to the blower (1) at a connecting location (2) to conduct flow. The connecting location (2) is configured at least as a double-winding connection (9) which has pairs of outer thread sections (4) of an outer winding (5) and inner thread sections (7) of an inner winding (8). The pairs are distributed about the periphery of the threaded connection. The periphery of the connecting location (2) is subdivided by the number of pairs of thread sections (4, 7) into a corresponding number of angular segments (10). The sum of angular extents (α, β) of a pair of individual thread sections (4, 7) is in total less than an angular extent (γ) of the corresponding angular segment (10).

    摘要: A two-cycle engine in a portable, manually-guided implement, such as a power chain saw, a cut-off machine, a brush cutter, or the like, is provided. The cylinder has a combustion chamber that is delimited by a reciprocating piston that via a connecting rod drives a crankshaft that is mounted in a crankcase so as to be rotatable about a crankshaft axis. The cylinder has an outlet for conveying exhaust gases out of the combustion chamber, with the outlet having an axis of the channel thereof. The cylinder also has an inlet for supplying a fuel/air mixture to the crankcase. By means of at least two transfer channels, the fuel/air mixture is conveyed out of the crankcase and into the combustion chamber, with the transfer channels being disposed symmetrically relative to the axis of the channel of the outlet. When viewed in the direction of the longitudinal axis of the cylinder, the axis of the channel of the outlet is disposed at an angle of less than 90° relative to the longitudinal central axis of the crankshaft.

    摘要: A carburetor arrangement for an internal combustion engine including a two-stroke engine in a portable handheld work apparatus includes an intake channel section (2) which is formed in the carburetor housing (34). A throttle flap (3) is arranged in the intake channel section and is rotatably held by a throttle flap shaft (4). Fuel-conducting channels open into the intake channel section (2) in the region of the throttle flap. A choke flap (5) is mounted upstream of the throttle flap (3) in the intake channel section (2). The choke flap (5) is held by a choke shaft (6) so as to be rotatable. The throttle flap (3) is displaced in a closing direction from an opening position into a closed position and in an opening direction from the closed position into the open position. The same applies to the choke flap (5). The choke flap (5) and the throttle flap (3) are mechanically coupled. The choke shaft (6) is actuable by an operator-controlled element. A choke lever (9) is mounted on the choke shaft 6 so that it cannot rotate relative thereto and a throttle lever (8) is mounted on the throttle shaft (4) so that it cannot rotate relative thereto. The choke lever (9) and the throttle lever (8) are in mutual engagement in a pregiven angular range of the position of the choke shaft (6) and an assigned angular range of the position of the throttle shaft (4).

    摘要: A valve drive mechanism is provided for an internal combustion engine, especially a four-stroke engine in a power chain saw. The implement housing is spanned by a front handle, the tubular grip of which is adjacent to the cylinder head of the engine and extends from one longitudinal side of the implement to the other longitudinal side thereof. A rocker arm of a valve control is pivotably mounted on the cylinder head between the ends of the rocker arm, with the rocker arm being pivotable about a pivot axis disposed transverse to the rocker arm. Push rods of a control mechanism engage one end of the rocker arm to actuate a poppet valve, on the valve stem of which the other end of the rocker arm acts. To be able to guide the tubular grip close to the center of gravity of the implement, the longitudinal axis of the rocker arm is disposed approximately parallel to the adjacent portion of the tubular grip.

    摘要: An actuating device for a decompression valve of an internal combustion engine with a cable starter, wherein the decompression valve is positioned within the cylinder of the internal combustion engine and comprises a valve member biased into its closed position, has a transmission lever having a longitudinal extension and being rotatable about its longitudinal axis. The transmission lever has a first and a second end. A cable drum for receiving the starter cable of the cable starter is provided. The cable drum has an axis of rotation about which the cable drum is rotated when the starter cable is pulled. The longitudinal axis of the transmission lever is perpendicular to the axis of rotation of the cable drum and spaced from the rotational plane of the cable drum. The cable drum entrains the first end of the transmission lever in the direction of rotation and thereby rotates the transmission lever about its longitudinal axis such that the second end of the transmission lever performs an adjusting movement for moving the decompression valve from the closed position into the open position.

    摘要: The invention is directed to a control system for a two-stroke engine for limiting a control quantity thereof such as the rotational speed. For this purpose, a pressure line including a valve is connected to the crankcase and leads to a pneumatic controlling member which is responsive to a mechanical or electrical signal (vibrations or electric pulse from the ignition system). By means of suitable transmission means, the movement of the controlling member is transmitted to the carburetor throttle, for example.

    摘要: A back carried work apparatus has a back carrier (2) with a back carrier plate (15). The back carrier plate (15) extends in an upward direction (21) and in a lateral direction (41) when the back carrier (2) is arranged on the back of an operator (14). A drive motor (8) is arranged on the back carrier (2) and rotatably drives a blower wheel (9) about a rotational axis (11) arranged transversely to the back carrier plate (15). The blower wheel (9) moves an air flow through the blower spiral (10) and blower tube (12) connected to the blower output (23) of the blower spiral (10). A simple configuration results when the blower tube (12) is pivotally mounted about a pivot axis (25) which extends in the lateral direction (41) of the back carrier plate (15).
