An automatic compression releasing device intended for reducing the pressure inside the combustion chamber of the four cycle engine at the start by opening and closing the intake or exhaust valve of the combustion chamber actuated by the cam on the cam shaft through the tappet. A single moving piece mounted, on the side of the gear integrated with the cam shaft, as enclosing the cam shaft, can slide over the side of the gear in a given direction, guided by two slots opened in the moving piece and two pins planted on the gear side. A tappet lifting arm is extended from the moving piece to such a position as to push up the tappet. At the start, the centrifugal force on the moving piece is designed not to exceed the opposing force, thus keeping the tappet lifting arm projected out of the cam base circle, and also retaining the returning force of the moving piece acting on the tappet lifting arm through the tappet being supported by the guide slots and pins. During the normal rpm, the centrifugal force on the moving piece overcomes aforesaid opposing force to slide the moving piece along said guide slots, bringing the tappet lifting arm level with or further down into the cam base circle.

Automatic compression releasing device for four-cycle engine

A suction air passage of the side-valve type of internal combustion engines is composed of a pipe-shaped portion which is integrated into the cylinder, for example by means of metal mold, and is opened at its outside, and a cover which is fixed to the pipe-shaped portion to close the opening thereof.

Suction air passage of internal combustion engine

A fuel supply system for a small engine including a constant level fuel chamber for receiving fuel from a fuel tank through a fuel drawing pipe to eject the fuel into a carburetor through a main nozzle after temporarily storing the fuel therein. A cover is provided to enclose the fuel drawing pipe and the constant level fuel chamber to separate the fuel drawing pipe and the constant level fuel chamber from a fuel storing section in the fuel tank, to enable fuel of a constant flow rate to be fed to the carburetor through the main nozzle irrespective of variations in the liquid level in the fuel storing section.
