摘要： PURPOSE:To shorten the overall length of a valve and to improve the maintenance characteristic of a filter by arranging a valve hole and the filter in the state of lining up both in the diametral direction of an injection flow passage and openably and closably providing the valve with an aperture capable of attaching and detaching the filter in a direction intersecting with the injection flow passage. CONSTITUTION:The valve hole 17 of the piston valve 6 which is opened and closed by movement of a piston valve body 18 toward a central axis X direction is arranged perpendicularly to the direction where its central axial line X intersects with the injection flow passage 2. The injection flow passage 2 and an introducing flow passage 4 are communicated and connected in the back and forth direction of the diametral direction of the infection flow passage 2 clamping the valve hole 17. A valve seat 19 is formed at the front end face of a valve hole forming member 13 and many slit flow passages 20 are formed at the base part of this valve hole forming member 13, by which the filter 21 of the high-pressure water flowing into the injection flow passage 2 is constituted. A valve seat fitting 14 and a plug 15 are freely attachably and detachably screwed to both ends of the valve body 16 to make both ends of the valve body 16 freely openable and closable. As a result, the filter 21 is made freely attachable and detachable.

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 provide a full cone nozzle, in which the precision of the flow rate of a jetted liquid is improved. SOLUTION: A liquid is introduced into a 1st liquid supply part 2, which is formed between a nozzle body 1 and a core 6, and a 2nd liquid supply part 20, which is formed in the central part side of the core 6 in the diameter direction, by forcibly charging the core 6 into a hollow part 5 formed in the nozzle body 1 to communicate with a liquid jetting port 4 of the nozzle body 1, and is jetted conically from the liquid jetting port 4 to flow while being turned and fluidized. A part 7 of the tip side of the core 6 formed into a conical taper shape to decrease the diameter toward the tip side is engaged with a part 8 of the hollow part formed into a conical taper shape to decrease the diameter toward the side nearer the liquid jetting port 4 and a prescribed number of liquid supply grooves 9 to jet the liquid so as to flow rotatably from the 1st liquid supply passage 2 by the engagement are provided on the core part 7.

摘要： PURPOSE:To reduce the thickness of the jet flow injected from an injection port and to increase the collision force per unit area so as to efficiently remove scale by providing flow regulating passages of the same diameter or approximately the same diameter over the entire length in the mid-way positions in the axial central direction of throttling passages on the same center over the length longer than the diameter of the flow regulating passages. CONSTITUTION:The two throttling passages B, C which are gradually smaller in diameter toward the injection port C1 side are provided on the same center between the flow regulator-contg. passage A in which the flow regulator 4 is mounted and the injection port C1. The flow regulating passages D, E of the same diameter or approximately the same diameter over the entire length are provided on the same center between these throttling passages B and C over the length longer than the diameter of these passages D, E. Consequently, the fluid regulated by passing the flow regulator- contg. passage is prevented from causing turbulence again at the time of passing the throttling passages while the flow velocity of this fluid is increased by the throttling passages. The thickness of the jet flow injected from the injection port is reduced in this way, by which the collision force per unit area is increased and the scale is efficiently removed.

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.
