摘要： PURPOSE:To obtain a nozzle not lowered in injection capacity even when an injection amount is altered and controlled to a large extent by providing a reduced pressure flow path supplying the liquid from a supply path to a revolving chamber while making the pressure thereof than the supply pressure in the supply path to a leading end part. CONSTITUTION:The leading end part 3a of a flow path forming member 3 is allowed to enter the conical revolving chamber-forming hole 2a of a nozzle forming body 2 and pressed to the nozzle forming body 2 by the clamping force of a supply and discharge member 5 to form a revolving chamber R. The kerosene supplied from a liquid supply pipe 6 under pressure through a filter 4 and the liquid supply path 8 formed by the liquid supply and discharge member 5 is supplied to the revolving chamber R under pressure by slitted supply paths 9. The kerosene from the supply paths 9 are revolved in a spiral state within the revolving chamber R to be injected from the jet orifice 10 of the nozzle forming body 2 in a mist form. As a result, an injection amount can widely be controlled.

摘要： PROBLEM TO BE SOLVED: To provide a fluid spouting device having a structure capable of generating a nozzle rotation by the hydraulic pressure and further, miniaturizing the driving part of a fluid supply pump or the like to a chamber and reducing the operation cost. SOLUTION: A washing water spouting device 40 is provided with an upper side through-hole 6A recessed so as to form an edge-shape and a recess 43 with a bottomed round hole shape. In the nozzle 4, the shrunk diameter part 7 at the extremity side of the nozzle is inserted in the upper side through-hole 6A and the lower end part 44 is inserted in recess 43 to assemble the spout device. The washing water spout 5 is exposed to the outside of the through-hole in the upper side through-hole 6A and made freely rotatable and the positional alternation of the nozzle in the nozzle axial center O direction is allowed. The nozzle can revolve around the central axis in the oblique posture to the center axis P of the upper side through-hole 6A. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To miniaturize a driving part such as a pump for supplying fluid to a chamber and to reduce operation costs by adopting a structure in which a nozzle is rotated by the pressure of the fluid. SOLUTION: A cleaning water ejection apparatus 40 has an upper side through hole 6A formed in the shape of an edge in the ceiling of the chamber 2 and a recessed part 43 in the shape of a bottomed round hole in the bottom surface. In the nozzle 4, a contraction part 7 on the tip side of the nozzle is inserted into the through hole 6A, and a lower end part 44 is inserted into the recessed part 43 to be incorporated. The nozzle 4, in the through hole 6A, makes a cleaning water ejection port 5 face the outside of the through hole 6A, and the position of the nozzle 4 is allowed to change freely rotatably and in the nozzle axis O direction. The nozzle 4 can rotate around the central axis in a posture inclined to the central axis P of the through hole 6A.

摘要： PROBLEM TO BE SOLVED: To propose a washing nozzle capable of efficiently rotating discharge water at high speed with little energy in the washing nozzle rotating the discharge water, and a sanitary washing device of a high sensation of washing even with a small quantity of wash water by rotating the discharge water at such a high speed that the private parts of a human body cannot sense. SOLUTION: The wash water supplied to this washing nozzle 6 flows into a swirling chamber 9 in the increased state of kinetic energy by the flow velocity increased by a swirling chamber flow straightening part 8 wherein the area of a water passage is narrower than that of a supply channel 7. The swirling chamber flow straightening part 8 is constituted to allow the wash water to flow into the swirling chamber 9 from a tangential direction. The wash water flowing into the swirling chamber 9 thereby swirls in the swirling chamber 9 and rotates a movable body 10 inserted in the swirling chamber 9, by imparting a part of the kinetic energy to blades 12 provided at the movable body 10. Then the wash water is jetted and discharged through a water supply port 13 and a discharge port 11 provided at the movable body 10.
