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： 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.

摘要： A diaphragm carburetor for a combustion engine having a manual starter has a housing and a control chamber arranged in the housing and filled with fuel. A suction channel is arranged in the housing and has a venturi section. A throttle flap is rotatably supported in the suction channel downstream of the venturi section in the flow direction of combustion air sucked into the suction channel. A main valve path connects a control chamber to the venturi section. An idle valve path connects the control chamber to the suction channel and opens into the suction channel at a location downstream of the throttle flap in the flow direction. A choke flap is rotatably supported in the suction channel and positioned upstream of the venturi section. The choke flap has identical cold start and warm start positions and allows a flow volume of combustion air into the suction channel sustaining engine operation after the engine has been started.

摘要： A closure arrangement of a container has fill socket with an inner thread and a closure cap with a cylindrical base body having an outer thread matching the inner thread of the fill socket of the container. The cylindrical base body has an annular flange adjacent to the outer thread. An annular seal, connected to one side of the annular flange facing the outer thread, is provided for sealingly resting on the rim of the fill socket when the closure cap is threaded into the fill socket. The outer thread has a resilient tongue extending in the circumferential direction of the cylindrical body and has a radial projection cooperating with the abutment of the matching inner thread. The radial projection, when the closure cap is threaded into the fill socket, catches in a catch position behind the abutment before a fully closed position of the closure cap in the fill socket is reached.

摘要： A two-stroke engine is disclosed which is controlled by a carburetor throttle valve and has a crankcase subjected to continuously alternating overpressure and underpressure. A pneumatic control member responsive to a signal dependent on the rotational speed of the engine is in pressure communication with the inner chamber of the crankcase via a valve. The output member of the pneumatic control member is connected with the throttle flap of the carburetor. The valve provided between the crankcase and the pneumatic control member is responsive to a signal for controlling the pressure in the pneumatic control member. This valve can be configured as a resonance control valve fixedly mounted to the housing of the engine. The resonance control valve has a mass oscillator which, at a correspondingly high engine speed and as a result of the vibration frequency associated therewith, acts upon a sealing diaphragm in the resonance control valve to open a pass-through opening communicating with the pneumatic control member.

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.
