FLUDIC APPARATUS SUCH AS SPRINKLER FOR FLUCTUATING OR CHANGING VELOCITY OF FLUID FLOWING OUT FROM NOZZLE AT SPECIFIC CYCLE OR PERIOD

摘要

PURPOSE: Provided is a fluidic apparatus being able to oscillate with stability even when it is made small in the sizes. CONSTITUTION: The fluidic apparatus includes a fluid inflow opening(1), a connector duct(2), and a fluid jet nozzle. The fluid within the connector duct is driven by pressure difference at the fluid jet nozzle portion. The jet nozzle portion is reversed in the pressure difference as a result thereof. The jet nozzle portion is driven and oscillating. The connector duct is constructed with a plural number of flow passages. The connector duct is made of two pieces of flow passages and is symmetric with each other. The fluid inflow opening and the fluid jet nozzle are disposed in a center between those two pieces of the of flow passages. The connector conduct is constructed with a curved surface, or a wind guiding plate is provided within the connector duct.
