Valve

摘要

A valve includes: a first chamber; a second chamber adjacent to the first chamber, and having a fuel discharge opening from which the fuel is discharged; an opening/closing hole configured to communicate the first chamber with the second chamber; an opening/closing member configured to open and close the opening/closing hole; a first contact spring having one end contacting an end of the opening/closing member at a side of the first chamber; a first control knob mounted to another end of the first contact spring; a diaphragm mounted to an end of the opening/closing member at a side of the second chamber; a second contact spring having one end connected to the diaphragm; and a second control knob coupled to another end of the second contact spring.

1. A valve, comprising:
a first chamber having a fuel supply opening configured to supply fuel for ignition; a second chamber adjacent to the first chamber, and having a fuel discharge opening from which the fuel is discharged; an opening/closing hole configured to communicate the first chamber with the second chamber; an opening/closing member configured to open and close the opening/closing hole; a first contact spring having one end contacting one end of the opening/closing member at a side of the first chamber, and configured to apply a first contact force to the opening/closing member; a first control knob mounted to the other end of the first contact spring, and configured to control the first contact force of the first contact spring; a diaphragm mounted to the other end of the opening/closing member at a side of the second chamber, and configured to open and close the opening/closing member; a second contact spring having one end connected to the diaphragm, and configured to apply a second contact force to the diaphragm in an opposite direction to the first contact force of the first contact spring; and a second control knob coupled to the other end of the second contact spring, and configured to control the second contact force of the second contact spring, wherein the opening/closing member includes: a bar installed to be linearly-movable through the opening/closing hole; and a sealing ring installed at the bar and configured to open and close the opening/closing hole at a side of the first chamber, a first locking protrusion configured to lock the sealing ring, the first locking protrusion being formed in the bar and adjacent to the sealing ring to be inclined from the sealing ring toward the second chamber, and wherein the opening/closing member is configured to control opening of the opening/closing hole by linearly moving toward or backward from the second chamber, according to a pressure inside the first chamber due to a supply pressure of fuel supplied from the fuel supply opening of the first chamber.
