A powered wheel assembly for use in connection with a wheelbarrow includes in one embodiment a frame that includes support members, a wheel assembly that includes a wheel, an axle, and axle housing, and a pin for connecting the axle and axle housing, and a drive assembly that includes a primary gear drive and a final chain drive. Upon retrofit to an existing wheelbarrow, the powered wheel assembly permits an operator to selectively operate the wheelbarrow in a powered and non-powered mode of transport.

The invention is directed to a membrane fuel pump for an internal combustion engine equipped with a membrane carburetor. The engine is that of a working apparatus and especially a handheld portable tool such as a motor-driven chain saw or the like. The membrane pump includes a drive chamber charged with the pressure inside the crankcase of the engine and a pump chamber separated from the drive chamber by a membrane. The pump chamber is connected at its suction end to a fuel tank via a first check valve and is connected to a pressure controller of the membrane carburetor at its pressure end via a second check valve. The pressure end of the membrane pump is connected with the suction end thereof via a bypass and a throttle is mounted in this bypass. With the throttle bypass between the pressure end and the suction end, the pumped volume is reduced at idle and the pump pressure is smoothed. Disturbances at the membrane carburetor are avoided.

A system for controlling a gas fuel flow in a fuel delivery system includes an on-demand pressure regulator. The pressure regulator includes an internal diaphragm configured to provide the gas fuel flow from an outlet port of the pressure regulator within a desired pressure range and a cut-off valve selectively blocking the gas fuel flow through the pressure regulator.
