Abstract
An injection nozzle for blowing air or injecting solvents reduces noise level and facilitates cleaning of injection passages. The injection nozzle includes a nozzle body provided with an opening and an inlet passage communicating with the opening. A plurality of grooves are provided on top and bottom sides of the nozzle body respectively. The nozzle body is also provided with upper and lower cover members, which can be selectively opened or closed. When the cover members are closed, an expansion chamber is defined by the opening and injection passages are defined by the grooves. The fluid to be injected from the inlet passage is expanded once in the expansion chamber and is then distributed through the injection passages for injection. Such expansion and contraction produces an effect of reducing noise level at the time of injection. Furthermore, the insides of the expansion chamber and the injection passages can be cleaned with ease by opening the cover members.
