Plunger valve for a propane carburetor

A propane carburetor, the propane carburetor comprising:

• an air intake, wherein the air intake allows air to enter the carburetor;
• a propane intake, wherein the propane intake:
• allows propane to enter the carburetor;
• and
• includes a plunger valve, wherein the plunger valve includes:
• a body, wherein the length of the body is between 13 and 20 millimeters;
• a set of flutes on the body configured to reduce wedging during operation and eliminate flutter when connected to a diaphragm between the fuel chamber and an external environment, wherein the set of flutes:
• includes at least four flutes;
• and
• are each symmetrically spaced about the axis of the body;
• and
• a conical tip, configured to create a secure seal and prevent propane leakage;
• a mixing chamber, wherein the propane entering the carburetor through the propane intake and the air entering the carburetor through the air intake are mixed in the mixing chamber;
• a passage connecting the propane intake to the mixing chamber;
• a disk actuator in the air intake, wherein the disk actuator includes:
• a disk;
• a plug, wherein the plug is connected to the disk such that rotation of the disk causes rotation of the plug and wherein the plug includes:
• a channel, wherein the channel is configured to regulate the flow of air into the carburetor;
• a base, wherein:
• the plug is capable of rotating relative to the base;
• rotation of the plug changes the distance between the plug and the base;
• a compressed spring wherein the compressed spring is configured to keep the plug in its furthest position from the base absent an external force;
• and
• a needle valve, wherein:
• the needle valve includes a needle-shaped plunger which regulates the flow of propane into a mixing chamber of the carburetor;
• at least a portion of the needle-shaped plunger is located within the plug;
• and
• the needle-shaped plunger includes a tip configured to be inserted into the end of the passage in the mixing chamber;
• the fuel chamber, wherein the fuel chamber is configured to store propane prior to mixing;
• the diaphragm between the fuel chamber and an external environment;
• a disk attached to the diaphragm, wherein the disk is configured to engage a first end of the lever;
• wherein the plunger valve is activated by a second end of the lever;
• a spring, wherein the spring is:
• in contact with the lever;
• and
• configured to bias the lever to hold the plunger valve in a closed position;
• and
• a cover over the diaphragm, wherein the cover includes an aperture.

A four stroke engine configured to operate using propane as a fuel source, the four stroke engine comprising:

• is configured to receive a propane air mixture;
• allows the propane/air mixture to undergo combustion;
• and
• output mechanical power;
• and
• a propane carburetor, the propane carburetor including:
• an air intake, wherein the air intake allows air to enter the carburetor;
• a propane intake, wherein the propane intake:
• allows propane to enter the carburetor;
• and
• includes a plunger valve, wherein the plunger valve includes:
• a body, wherein the length of the body is between 13 and 20 millimeters;
