Abstract

A fuel powered paint marker having a first stage and a second stage comprising: a housing; a combustion chamber; a piston; a compression chamber; a fuel system; an oxidizing system; an oxidizing agent; a fuel assembly included in the fuel system; a separation assembly included in the fuel system and separating the oxidizing agent from the fuel assembly in the first stage; a bolt drive system; a fuel nozzle included in the fuel system for injecting fuel into the combustion chamber during the second stage; and, an ignition for igniting the fuel and oxidating agent in the combustion chamber driving the piston forward and compressing a gas in the compression chamber thereby ejecting a projectile wherein the fuel and oxidizing agent are separated during the first stage and mixed in the combustion chamber.

Dependent claims

A fuel powered paint marker having a first stage and a second stage comprising:

a housing having a cavity defined in the housing;
a piston received in the housing;
a combustion chamber defined by the housing and a first side of the piston;
a compression chamber defined by the housing and a second side of the piston;
a fuel system carried by the housing and in fluid communications with the combustion chamber;
an oxidizing system included in the fuel system having an oxidizing input for receiving an oxidizing agent wherein the oxidizing agent enters the oxidizing system during the first stage;
an oxidizing output included in the oxidizing system;
a fuel assembly included in the fuel system having a fuel input wherein fuel enters the fuel assembly during the first stage;
a separation assembly included in the fuel system and separating the oxidizing agent from the fuel assembly in the first stage;
a bolt drive system carried by the housing having a bolt piston, bolt drive rod and a bolt;
a first oxidizing input included in the bolt drive system in fluid communication with the oxidizing output wherein the oxidizing agent is inserted into a bolt piston chamber driving the bolt piston forward thereby closing the bolt;
a second oxidizing input included in the bolt drive system in fluid communication with the oxidizing output wherein the oxidizing agent is inserted into a bolt reservoir chamber during the first stage and the oxidizing agent is injected into the combustion chamber during the second stage;
a fuel nozzle included in the fuel system for injecting fuel into the combustion chamber during the second stage;
and,
an ignition for igniting the fuel and oxidizing agent in the combustion chamber driving the piston forward and compressing a gas in the compression chamber thereby ejecting a projectile.

a housing having a cavity defined in the housing and a piston received in the housing;
a combustion chamber defined by the housing and a first side of the piston;
a compression chamber defined by the housing and a second side of the piston;
a fuel system carried by the housing and in fluid communications with the combustion chamber adapted to receive fuel from a fuel source during the first stage and inject the fuel into the combustion chamber during a second stage;
an oxidizing system carried by the housing adapted for receiving an oxidizing agent from an oxidizing agent source wherein the oxidizing agent enters the combustion chamber during the first stage;
a separation assembly carried by the housing and adapted to separate the oxidizing agent from the fuel system during the first stage;
a bolt drive system carried by the housing having a bolt piston, bolt drive rod and a bolt and in fluid communications with the oxidizing system wherein the bolt drive system receives the oxidizing agent into a bolt reservoir chamber during the first stage and into a bolt piston chamber driving the bolt piston forward thereby closing the bolt during the second stage and injecting the oxidizing agent into the combustion chamber during the second stage;
an ignition for igniting the fuel and oxidizing agent in the combustion chamber driving the piston forward and compressing a gas in the compression chamber thereby ejecting a projectile.
