摘要： A fuel supply system for small two-stroke internal combustion engines for e.g. chain saws, line trimmers and similar hand-held power-tools including a diaphragm carburetor (20) equipped with a purging system (80a, 81a) or priming system (80b, 81b) for facilitating starting of the engine (1). Downstream of the diaphragm (30), the carburetor has a fuel valve (60) with a fuel cavity (73), which when the valve is not closed being connected via a fuel conduit (37) to a fuel nozzle (35, 36) in a main air passage (21) in the carburetor. The purging system or priming system including a fuel line (80a; 80b), which is provided with a manually operated pump (81a; 81b) and is connected between a fuel tank (26) and either the fuel cavity (73) or the fuel conduit (37).

摘要： An adaptor includes a body having a cap portion, a bottle portion and an optional collar between the cap portion and the bottle portion. A supply fitting and a return fitting are coupled to the cap portion of the body. The adaptor may be coupled to a liquid fuel bottle, such as a white gasoline container, to form a removable fuel tank that may be used with a portable generator having a carbureted internal combustion engine.

摘要： A starting device for feeding a quantity of fuel from the fixed-quantity fuel chamber to an intake passage during start-up having a manually operated primary pump for suctioning/pumping fuel and arranged on a fuel introduction path connected along a fuel-feeding path; and a fixed-quantity fuel chamber for temporarily storing fuel delivered from the primary pump. An internal wall of the fixed-quantity fuel chamber undergoes elastic displacement, allowing its internal capacity to expand/shrink within a predetermined range; the fixed-quantity fuel chamber is connected to a fuel delivery path that communicates with the intake passage side and has a manually operated open/close valve; the valve is opened in a state in which, due to the primary pump being operated, the fixed-quantity fuel chamber is filled with a predetermined quantity of fuel while enlarging its internal capacity, whereby it shrinks due to an elastic contraction force and the fuel.

摘要： A starting element (100) for use, for example, in a drivetrain of a motor vehicle, includes a piston (310) which divides a first volume (560) that can be filled with a fluid from a second volume (570) that can be filled with a fluid, wherein the piston (310) comprises at least one fluid passage (640) which allows the fluid at least occasionally to pass through the piston (310) from the first volume (560) into the second volume (570) and/or from the second volume (570) into the first volume (560). The at least one fluid passage (640) comprises a passage component part (650) and a receiving opening (660) in the piston (310). The passage component part (650) is inserted into the receiving opening so that at least one passage opening (670) is formed which allows the fluid to pass through at least occasionally.

摘要： A carburetor provides a supplemental fuel supply to an engine and includes a body, a fuel metering diaphragm and a fluid pump. The fuel metering diaphragm defines part of a fuel metering chamber and a reference chamber and has at least a portion that is movable relative to the body to increase and decrease the volume of the fuel metering chamber to control fuel flow in the fuel metering chamber. The fluid pump is carried by the carburetor or another component upstream of the carburetor and has an outlet in fluid communication with the metering reference chamber and an actuator arranged to discharge fluid through the outlet to increase the pressure within the metering reference chamber and thereby increase the fuel flow rate from the fuel metering chamber to the air-fuel passage to provide a supplemental fuel supply to the engine.
