摘要： The invention is directed to a pressure compensating valve for a fuel tank of a work apparatus such as a portable handheld work apparatus equipped with an internal combustion engine. The fuel tank has a tank wall and the pressure compensating valve includes a housing cap defining an inner space and is impermeable to air. A pressure compensating stub is provided on the tank wall and terminates within the housing cap. Pressure compensating apertures are formed in the tank wall to open into the stub and a valve is provided for controlling the apertures for venting and ventilating the fuel tank. A passage connects the inner space of the cap with the atmosphere. A finely porous filter element is fixedly held in the stub and the apertures open into the filter element. The housing cap is mounted on the filter element and is held on the filter element.

摘要： An internal combustion engine having an intake channel that opens into a crankcase. A first fuel channel opens into the intake channel to supply fuel thereto as a function of underpressure in the intake channel. An auxiliary channel opens into a transfer channel that fluidically connects a crankcase to the combustion chamber. A second fuel channel opens into the auxiliary channel and is connected to a storage reservoir for fuel. At least one valve controls the quantity of fuel to be supplied to the engine via the auxiliary channel. Largely fuel-free air is supplied to the engine via the intake channel during idling. During a first revolution of the crankshaft, fuel is supplied via the auxiliary channel, so that a combustible mixture can form in the combustion chamber. During a second revolution, largely fuel-free air is supplied via the auxiliary channel and the combustion chamber is scavenged with largely fuel-free air.

摘要： A method is for controlling the metering of fuel in a fuel system (30) of an internal combustion engine (1) which is to be started manually. This control is with a currentless open electromagnetic valve (21). The electromagnetic valve (21) is only switched into the closed state when a supply voltage (Uv) is applied and current flows. Within a blocking time (47), which is pregiven by an engine control (13), a supply voltage (Uv) is switched onto the excitation coil of the electromagnetic valve (21) only and the valve (21) is supplied with current only when an underpressure is present in the intake channel (11) of the fuel system (30); whereas, in the remaining time span (50) of the blocking time (47), wherein no underpressure is present, the control unit (20) switches off the supply voltage (Uv) and the valve (21) is in the currentless open state.

摘要： An electromagnetic valve (1, 21) includes a coil (2) which is fixedly connected to an iron core (3). An armature plate (5) is movably journalled in the direction of the coil longitudinal axis (22) relative to the iron core (3). At least two flow channels (8, 9; 26, 27, 28, 29) open at the armature plate (5) and are fluidly separated from each other when a current flows in the coil (2). A small structural size with a simple manufacture of the electromagnetic valve (1, 21) is achieved in that a flow channel (8; 26, 27, 28) opens in the peripheral region (32) of the armature plate (5) at the end (33) of the armature plate (5) facing toward the coil (2).

摘要： A carburetor arrangement is provided for an internal combustion engine that is to be started with a pull cord. A fuel channel that is connected with a fuel-filled storage space opens into and supplies fuel to an intake channel portion as a function of the underpressure in the intake channel portion. The underpressure in the intake channel portion is increased during the start-up process via a start-up mechanism. To keep the engine ready to run with the start-up mechanism engaged, a control valve is disposed between the storage space and where the fuel channel opens into the intake channel portion. The control valve is opened or closed by a control unit as a function of the speed of the internal combustion engine.

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.
