Abstract
A flame gun with a flow control ring includes a body with a gas outlet assembly disposed therein. The gas outlet assembly includes a flow regulator being rotatable about an axis. A flow controller is coupled to and operably rotatable relative to the body. The flow controller is configured to drive the flow regulator rotationally and includes a connecting portion connected to the flow regulator. The flow controller includes an input portion disposed in a spaced relationship with the connecting portion and includes at least one link arm interconnecting and extending between the connecting portion and the input portion. The input portion is disposed circumferentially and surrounds at least half an outer periphery of the body.
Claims17
A flame gun with a flow control ring comprising:
- a body having a grip portion and a flame head portion and including a gas outlet assembly disposed therein with a first end connected to and in fluid communication with a fuel canister and a second end connected to and in fluid communication with a passage of the flame head portion, and wherein the gas outlet assembly includes a flow regulator being rotatable about an axis to adjust the size of an opening between the fuel passage and the fuel canister;
- and
- a flow controller coupled to and operably rotatable relative to the body, wherein the flow controller is configured to drive the flow regulator rotationally and includes a connecting portion connected to the flow regulator, wherein the flow controller includes an input portion disposed in a spaced relationship with the connecting portion and includes at least one link arm interconnecting and extending between the connecting portion and the input portion, and wherein the input portion is disposed circumferentially and surrounds at least half an outer periphery of the body,
- wherein the input portion and the grip portion are arranged along the axis.
