    摘要: A vale unit includes a valve frame and two valve plates. The valve frame defines a valve opening. The valve plates are formed with protrusions. Each of the valve plates has a connecting end that is formed with a notch. The connecting ends are connected to each other. The protrusions protrude from peripheries of the notches. Each of the protrusions has a contact end. The contact ends cooperatively define a gap therebetween. The valve plates are co-rotatable about an axis between a closed position, in which the valve plates substantially close the valve opening, and an opening position, in which the valve plates open the valve opening. The gap has a width varying in response to co-rotation of the valve plates between the opening position and the closed position.

    摘要: A nozzle device includes a nozzle body and at least one second electrode. The nozzle body extends along a longitudinal axis, and has a top surface, a bottom surface for confronting a first electrode of a workpiece, a recess provided in the bottom surface, and a longitudinal channel extending downwardly from the top surface along the longitudinal axis to be in fluid communication with the recess. The longitudinal channel has an upper section and a lower tapered section which is tapered downwardly to form a lower communication port. The least one second electrode is disposed in the recess for being spaced apart from the first electrode.
