摘要：

A dripless atomizing nozzle may include a nozzle body having a liquid orifice in fluid communication with a liquid inlet, a gas orifice in communication with a gas inlet, and a liquid passage connecting the liquid inlet and the liquid orifice, and a piston body having a piston passage communicating with the gas inlet; the nozzle body may include a connecting portion shaped to enable the piston body to be selectively removed from and attached to the nozzle body. A piston positioned in the piston passage may include a stem and a bias element connected to move the piston and stem within the piston passage such that the presence of gas above a predetermined pressure in the piston passage overcomes a force of the bias element to displace the piston to move the tip away from the liquid orifice to open the liquid orifice.
