    摘要: A dental syringe employs a single thumb or finger operated control member mounted on the syringe for regulating the flow of air or water or spray. The single control moves axially and vertically with respect to the syringe. Axial movement either forward or rearward from a rest position, initiates and controls the quantity of flow of air or water. Vertical movement of the control member initiates the flow of both air and water to produce a spray.

    摘要: A fluid flow control valve uses a solenoid to control flow wherein the fluid path extends axially through the core of the solenoid. Flow is variable over the range of 0 to maximum flow and varies linearly with the voltage applied to the solenoid coil.
