Abstract: An injector has an orifice plate formed with plural orifices. At a radially outward position of the orifice plate is disposed a wall at least partially. It is preferable that the wall be disposed at a lower position in the direction of gravity. In the wall is formed a guide hole toward an area on the orifice plate where a strong negative pressure is developed. A portion of fuel injected from the injector adheres as adhered fuel to the orifice plate or the wall. Under the action of a negative pressure on the orifice plate the guide hole sucks in the adhered fuel and returns it onto the surface of the orifice plate. The adhered fuel flows from the wall onto the surface of the orifice plate and again joins a fuel jet injected from the orifices. By utilizing a negative pressure developed near the plural orifices, the adhered fuel can be recovered and again injected. Consequently, it is possible to decrease the amount of adhered fuel.

Abstract: An annular body has an outer wall member and an inner wall member. A hollow space is present between these two wall members. A connector in the outer wall member provides for a communication between the hollow space and a source of induced draught. The inner wall includes perforations and through holes which form a communication between the space surrounded from the inner wall and the hollow space and finally the connector to the source of induced draught. A rib is located at the lower end of the annular body. If the apparatus is placed on an area of a material, against which cleaning fluids are sprayed, the inner wall limits a spreading of the liquid bouncing away from the material. The liquid flowing down the inner wall is transported off specifically through the perforations. Liquid spreading on the material is transported off by further through holes located at the rib.
