Abstract
A one-step starting carburetor system includes a body, a middle body, a fuel inlet pipe, a fuel outlet pipe, a lower cover and a temperature controller which is connected to the lower cover. The fuel inlet pipe pumps fuel from an oiler through the pipe. The fuel outlet pipe connects with an oil pumping unit through a pipe. The body connects with a pulse generator through a pipe, wherein the pulse generator comprises a pulse generating chamber, a cover, and a solenoid valve.
Claims21
A one-step starting carburetor system, comprising:
- a body, a middle body, a fuel inlet pipe, a fuel outlet pipe, a lower cover and a temperature controller which is connected with the lower cover,
- wherein the fuel inlet pipe pumps fuel from an oiler through a pipe;
- the fuel outlet pipe connects with an oil pumping unit through a pipe;
- the body connects with a pulse generator through a pipe, wherein the pulse generator comprises a pulse generating chamber, a cover, and a solenoid valve;
- and
- wherein the temperature controller includes a copper base in which a paraffin is disposed, a diaphragm disposed between a fluid medium and the paraffin, a plunger slidable in a hollow chamber, a top pole comprised of an elongate part having a diameter less than the hollow chamber so that air from an air vent can enter the hollow chamber, and a return spring to bias the top pole to a position where air flow through the air vent is closed off.

- the fuel outlet pipe connects with an oil pumping unit through a pipe;
- the body connects with a pulse generator through a pipe, wherein the pulse generator comprises a pulse generating chamber, a cover, and a solenoid valve;
- wherein the oil pumping unit and the pulse generator are both put up along a magneto of an engine;
- wherein a flywheel is put up on the magneto, and a pulse chamber of the pulse generator inhales and exhales when the flywheel is operating;
- wherein the flywheel has magnets and the pulse generator has a magnet, and wherein the magnets of the flywheel and the magnet of the pulse generator attract or repel each other when the flywheel is operating;
- wherein the pulse generating chamber inhales when the magnets of the flywheel and the magnet of the pulse generator attract each other;
- wherein an inhalation pulse and an exhalation pulse generated by the magnets of the flywheel and the magnet of the pulse generator, only the exhalation pulse can enter into a chamber of the lower cover of the carburetor through a crowding pipe due to a one-way valve;
- more fuel is sprayed out from the main nozzle of the carburetor by pushing a metering diaphragm when a solenoid valve is open, and mixed gas is concentrated in a mixing chamber to start the engine easily;
- and
- wherein the temperature controller includes a copper base in which a paraffin is disposed, a diaphragm disposed between a fluid medium and the paraffin, a plunger slidable in a hollow chamber, a top pole comprised of an elongate part having a diameter less than the hollow chamber so that air from an air vent can enter the hollow chamber, and a return spring to bias the top pole to a position where air flow through the air vent is closed off.
