摘要： A portable handheld work apparatus such as a motor-driven chain saw (1) includes a housing (2) wherein an internal combustion engine (10) and a carburetor (11) are mounted. A throttle lever (6) is provided which is pivotally journalled on a handle (3). The handle (3) is connected to the housing (2) via at least one antivibration element (33). A vibration gap (9) is configured between the handle (3) and the housing (2). A transmitting unit (13) is provided for transmitting the pivot movement of the throttle lever (6) to the carburetor (11). The transmitting unit includes a rigid transmitting element (17, 37) which bridges the vibration gap (9). A simple configuration and a substantial decoupling of the relative movement between the housing (2) and the handle (3) from the actuating movement of the carburetor is achieved in that the transmitting element (17, 37) is rotatably journalled and the pivot movement of the throttle lever (6) is transmitted as a rotation about a rotational axis (22) lying transverse to the vibration gap (9).

摘要： A hand-held working tool has a housing and an internal combustion engine arranged in the housing and comprising a crankshaft and an air filter. A tool is driven by the crankshaft of the internal combustion engine. A fan housing is attached to the engine housing and has an air inlet. A fan wheel is arranged in the fan housing and is driven by the crankshaft of the internal combustion engine to supply cooling air, sucked in through the air inlet, to the internal combustion engine. The fan housing has a bottom extending radially to the crankshaft. The bottom and a side of the fan wheel facing the bottom define a chamber in the fan housing. The bottom has a combustion air outlet. A combustion air channel is connected to the combustion air outlet and to the air filter. The combustion air outlet is axially supplying combustion air from the chamber through the combustion air channel into the air filter of internal combustion engine. The fan housing has a channel wall having a bottom portion connected to the face of the bottom remote from the fan wheel and covering the bottom partially to form a double-walled bottom. The end face portion of the combustion air channel is defined by the bottom and the bottom portion of the channel wall. In an alternative embodiment the combustion air channel is provided in a hollow beam of a support that supports the drive unit of the working tool.

摘要： An arrangement for decanting liquids includes a tubular-shaped support (1) having a flow channel (2). The flow channel (2) is blocked by a valve plate (3) which is coupled via axial connecting elements (4, 4′) to the relative movement of an inner sleeve (5) and an outer sleeve (6) of the support (1). The outer sleeve (6) lies in overlapment and the axial connecting elements (4, 4′) extend into the interior of the support. The valve plate (3) can be lifted from its valve seat against a spring force engaging at the inner sleeve (5) and at the outer sleeve (6). A radial flange collar (13) is formed on the outer sleeve (6). To ensure an accurate metering at the highest possible volume flow of the discharged liquid at low manufacturing costs, the valve plate (3) is mounted at a free end (9) of the support (1) and the axial connecting elements are configured as tension rods (4, 4′) and are arranged next to an edge of the valve plate (3).

摘要： The invention is directed to a tensioning arrangement for saw chains of motor-driven chain saws which include a device for longitudinally displacing the guide bar. The clamped guide bar is released so that the adjusting arrangement can be actuated for the longitudinal displacement of the guide bar. By rotating a disc having a spiral slot, a slide piece, which is coupled to the guide bar, is displaced in the longitudinal direction. Assembly is simplified and handling facilitated when the tension in the saw chain is adjusted. This is achieved by making the slide piece on the spiral disc so that it is not released therefrom but instead is held so as to be rotationally and longitudinally displaceable. The slide piece is fixedly connected to the guide bar by using appropriate attachment devices.

摘要： The invention is directed to a tensioning arrangement for a saw chain of a motor-driven chain saw. The saw chain runs on a guide bar mounted on the motor housing of the chain saw. The tensioning arrangement includes a rotatable disc having a spirally-shaped guide slot in which a lug of a slide piece engages. The longitudinal displacement of the guide bar is provided by rotating the disc. The guide slot in the disc extends over a rotational angle of at least 270.degree.. A still lesser slope of the guide slot is provided with a rotational angle in the range of 360.degree. to 450.degree.. The tensioning arrangement is especially suitable for adjusting the guide bar in motor-driven chain saws thereby adjusting the tension in the saw chain.

摘要： The invention is directed to a braking arrangement for a chain saw having a housing and a guide bar mounted on the housing for accommodating a saw chain thereon. The brake arrangement includes a brake drum operatively connected to the saw chain with a brake band disposed in surrounding relationship thereto. A brake member is connected to the brake band and moves between a ready position whereat the brake band is disposed in spaced relationship to the brake drum and a released position whereat the brake band is drawn tightly around the brake drum. A brake spring resiliently biases the brake member to cause the brake member to pull the brake band tightly about the brake drum when in the released position. A latch arrangement holds the brake member in the ready position against the force of the brake spring. A cam connected to the drive motor rotates through a predetermined path. A release device opens the latch arrangement to permit rotational movement of the brake member to the released position and releases a tensioning member for movement into the path of the cam when the brake member is in the second position whereat the tensioning member follows the cam in a movement that causes the tensioning member to again coact with the latch arrangement to return the brake member to the ready position and to reclose the latch arrangement whereby the latter again holds the brake member in the ready position against the force of the brake spring.
