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.

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.

A handheld work apparatus has a fuel supply system and a pump for delivering fuel from the fuel supply system. The pump has an elastic pump bellows which can be actuated by the operator. The pump bellows has a fastening section at which the pump bellows is fastened to a housing. The pump bellows has a main section and a roof section, wherein the roof section has a dome-shaped section adjoining the main section and a cap which adjoins the dome-shaped section and closes off the dome-shaped section. In order to achieve a rapid return of the pump bellows from the actuated position into the unactuated position, even at low temperatures, it is provided that the smallest wall thickness (g) of the main section is at least 10% greater than the smallest wall thickness (h) of the dome-shaped section.

A garden tool includes a gasoline engine and a power source, the gasoline engine including a fuel supply system and an ignition system. The garden tool may further include a control system with at least one sensor used for collecting a working condition signal of the gasoline engine and a controller used for receiving the working condition signal and controlling the fuel supply system and/or the ignition system according to the working condition signal received. The power source may provide a power supply for the fuel supply system, the ignition system, and the control system through the controller.

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.

An apparatus for delivering a fuel-air mixture to an engine is provided. The apparatus includes: a carburetor having one or more passages and one or more chambers, wherein at least some of the passages and chambers are in communication with one another; and a fluid pump communicated with the carburetor and pumping fluid into or out of the carburetor to influence an fuel-to-air ratio of a fuel and air mixture delivered from the carburetor.

This present invention relates to the field of carburetor, in particular, relates to a fuel enrichment simple starting device and method of carburetor, using pre-injection technology to achieve engine fuel enrichment start, That is, in the first step squeeze the purge bulb, pre-inject the quantitative fuel, and then use the choke of the large volume air to achieve simple start, steps: the first step, squeeze the purge bulb; the second step, close the choke; the third step, pull the engine starter to the engine running; the fourth step, increase and decrease the throttle to normal running. If using the fuel enrichment simple starting device and method of carburetor in the present invention, the engine can be started completely by above four steps, the starting device has the advantages of simple operation, less starting times and easy to start at low temperature (such as 0 C.).
