Abstract
This invention has an object to provide a fuel pressurizing apparatus which is light, compact, durable and inexpensive whereby a working machine can be operated even on a slope without difficulty. In order to achieve this object, a pressure adjusting chamber is formed in a portion of a passage in a breather device of an engine, and a pipe conduit is provided to communicate the pressure adjusting chamber with a fuel tank. A check valve which does not allow fuel from the fuel tank to pass is provided in a portion of this pipe conduit. A vent hole which is constantly open is provided in the fuel tank, and a cross-sectional area of the vent hole is set to maintain balance of a pressure from the pressure adjusting chamber with a pressure required for the fuel tank. A space is formed in an upper portion of the fuel tank so as to project therefrom. The fuel tank is shaped like a triangular flask, and the pipe conduit from the pressure adjusting chamber is connected to the projecting space in the upper portion of the fuel tank. Thus, the fuel tank pressurizing apparatus can be operated more reliably.
