The valve member is an integral body having a left tube, a right tube, and a connection tube between the left tube and the right tube in a single member. The valve member further has a gas channel therein extended from the left tube, the connection tube to the right tube in sequence and a first bore on the left tube to be communicated with the gas channel. The connection tube has an inlet to be connected to an external gas supply. The first sealing member may be moved to seal the first bore of the gas channel. The present invention has many advantages including strong structure, high precision, and easy for fabrication and assembly. | 11-05-2009 |
20090206291 | GAS FLOW RATE CONTROL VALVE - A gas flow rate control valve includes a lower valve block defining a gas flow passage, and an upper valve block having a tube disposed ill communication with the gas flow passage, and a solenoid coil assembly surrounding the tube for generating a magnetic field. A magnetic column has a magnetic portion inserted into the tube and axially movable by the magnetic field generated by the solenoid coil assembly, and a stopper movable with the magnetic portion to change the open cross-sectional area of the gas flow passage so as to control the flow rate of the fuel gas passing through the gas flow passage. A spring member is provided at one of the top and bottom sides of the magnetic column to keep the magnetic column in balance and to provide a return force to the magnetic column after displacement of the magnetic column. | 08-20-2009 |
