va Liquid feed valve unit and liquid ejection device By www.freepatentsonline.com Published On :: Tue, 26 May 2015 08:00:00 EDT A liquid feed valve unit is configured to switch between a releasing mode for forcibly opening a valve and a blocking mode for closing the valve, and the valve can therefore be opened and closed in a short time as needed. Since the releasing mode is implemented by pushing the peripheral part and the pressure-receiving part of the flexible member, the flexible member can be prevented from flexing toward the outside of the liquid accommodating chamber even in the case that the pressure-receiving part is pushed. In this case, since a residual pressure can be prevented from forming in the liquid accommodating chamber, there is no need to suspend operation, and it is possible to immediately proceed to the next operation. A fast-operating liquid feed valve unit can thereby be obtained. Full Article

va Method for varying oscillation frequency of high frequency oscillator By www.freepatentsonline.com Published On :: Tue, 19 May 2015 08:00:00 EDT The switching element is provided in a state of being electromagnetically coupled to the cavity resonator of the high frequency oscillator; the bias voltage applying terminal is connected to one electrode of the switching element; another electrode of the switching element is electrically connected to the cavity resonator (the anode shell in FIG. 1); the metal plate having a size enough for reflecting an electric wave to be transmitted before and after the switching element in a high-frequency manner is provided at any one end of the switching element; and by applying a bias voltage to the switching element and varying that, a reactance of the switching element is changed and a resonance frequency of the cavity resonator is varied. By this method, an oscillation frequency can be varied greatly relative to a small change in a bias voltage. Full Article

va Solenoid valve having air tap structure By www.freepatentsonline.com Published On :: Tue, 05 May 2015 08:00:00 EDT A solenoid valve includes a plunger, an actuating device, and an air tap assembly. The plunger is connected to the actuating device. The air tap assembly is secured to the actuating device and has a cavity. The air tap assembly includes a main body, and first and second tubes. The first tube protrudes from the main body and defines a first through hole. The main body defines a second through hole communicated with the first through hole and the cavity. The second tube defines a third through hole. The main body defines a fourth through hole extended from the third through hole and a fifth through hole extended from the fourth through hole to the cavity. The fifth and second through holes are parallel. The plunger head is used to seal the second and fifth through holes. Full Article

va Butterfly valve By www.freepatentsonline.com Published On :: Tue, 05 May 2015 08:00:00 EDT A butterfly valve (100) is provided. The butterfly valve (100) includes a valve body (103) including a valve bore (109) passing through the valve body (103), with the valve bore (109) including an upstream valve bore portion (109U) and a downstream valve bore portion (109D), a shaft bore (112), a valve shaft (121) located in the shaft bore (112) and extending substantially across the valve bore (109), and a valve flap (107) affixed to the valve shaft (121) and configured to be rotated by the valve shaft (121). The valve flap (107) is configured to rotate between a closed orientation blocking the valve bore (109) and an open orientation. The valve flap (107) is affixed on an upstream valve bore portion side of the valve shaft (121), wherein incoming fluid presses the valve flap (107) against the valve shaft (121). Full Article
va Hard seal plug valve By www.freepatentsonline.com Published On :: Tue, 05 May 2015 08:00:00 EDT The invention provides a hard seal plug valve, comprising a valve body, wherein a tapered plug is arranged in the valve body, a bonnet is arranged at an upper part of the valve body, a drive valve rod penetrates the bonnet, an elastic hold-down mechanism is sheathed on the drive valve rod and arranged on a plug bearing seat, the plug bearing seat is connected with the tapered plug, and the plug bearing seat is held down when the elastic hold-down mechanism extends; and the hard seal plug valve characterized in that a telescopic mechanism is sheathed on the drive valve rod, the plug bearing seat is pushed upward when the telescopic mechanism extends, a valve rod bearing seat is arranged at the bottom of the drive valve rod, ends of the valve rod bearing seat pass through a planetary reduction mechanism, and the tapered plug is connected with the planetary reduction mechanism and rotates with the drive valve rod by the planetary reduction mechanism. In the invention, the tapered plug can reliably float and rotate under any circumstances. The drive torque of the plug valve is at least 7 times less than that of a general plug valve, therefore, when a motor is used, a general valve requires 2 minutes from opening to closing, and the valve of the invention only requires 3.8 seconds.
