Abstract: A container includes a container main body including a housing part and an opening, and a lid configured to close the opening and including an insertion part configured to be inserted to the opening. The outer peripheral surface of the insertion part includes first and second protrusions and first and second recesses. The inner peripheral surface of the opening includes third and fourth protrusions and third and fourth recesses. When the insertion part is temporarily inserted to the opening, the third protrusion presses the first recess in a state where the first protrusion is housed in the third recess. When the insertion part is fully inserted to the opening, the third protrusion presses the second recess and the fourth protrusion presses the first recess in a state where the first protrusion is housed in the fourth recess and the second protrusion is housed in the third recess.

Abstract: An emitter includes a water intake part, a pressure-reducing flow path part, a first flow-rate adjusting part, a second flow-rate adjusting part, and a discharge part. The first flow-rate adjusting part includes a first valve seat, a first communication hole, a first diaphragm part, and a valve body. The valve body is disposed between the first diaphragm part and an opening of the first communication hole. The valve body moves toward the first communication hole as the first diaphragm part approaches the first valve seat. The shape of the valve body is such that, when the traveling distance of the valve body is less than or equal to a predetermined value, the gap decreases as the valve body moves and such that, when the traveling distance of the valve body exceeds the predetermined value, the gap increases as the valve body moves.

Abstract: This emitter (120) comprises: a first flow rate adjustment unit which adjusts the flow rate of an irrigation liquid according to the deformation of a first diaphragm (160); and a second flow rate adjustment unit which adjusts the amount of irrigation liquid ejected (discharged) from the emitter (120) according to the deformation of a second diaphragm (170). The first diaphragm (160) has a projection spaced apart by a space from a hole which is a flow path for the irrigation liquid. The projection has an inverted truncated cone shape and is formed so that the space widens as the projection goes into the hole.

Abstract: A nozzle hole of a nozzle plate is connected to a fuel injection nozzle of a fuel injection unit through a swirl chamber and first and second fuel guide grooves opened to the swirl chamber. The swirl chamber is an oval recess provided with the nozzle orifice in its center. A first fuel guide groove is opened to one end side of a major axis of the oval recess, and a second fuel guide groove is opened to the other end side of the major axis of the oval recess. The first and second fuel guide grooves are formed such that the same amount of fuel flows to the swirl chamber. The same amount of fuel flowing from the first and second fuel guide grooves to the swirl chamber is guided to the nozzle orifice at the same time while revolving inside the swirl chamber in the same direction.

Abstract: A metal valve body having a fuel injection port includes a nozzle plate accommodation part accommodating a nozzle plate of synthetic resin and aligning a center of the nozzle plate with a central axis of the valve body. A front end surface abutting against the nozzle plate is accommodated in the nozzle plate accommodation part. A swage projection fixes the nozzle plate to the front end side on which the fuel injection port is formed. The nozzle plate is swage-fixed in the state in which a spring action part is elastically deformed on the front end side of the valve body by the swage projection, and a nozzle hole formation part is constantly pushed against the front end surface of the valve body by the elastic force of the spring action part.

Abstract: In a nozzle plate, a portion of fuel flowing out from a fuel injection port of the fuel injection device is atomized by impinging on an interference body. At the same time, the flow of the portion of fuel is sharply bent and impinges on fuel which straightly advances and passes through a nozzle hole and an orifice thus turning the flow of fuel into a turbulent flow. Further, both end portions of the orifice form non-rounded sharpened corner portions. Hence, a liquid film of fuel injected from the corner portions and areas in the vicinity of the corner portions of the orifice is formed into a thin sharpened and pointed state whereby an end portion of the liquid film of fuel injected from the orifice is easily atomized due to a friction between the end portion of the liquid film of fuel and air.
Abstract translation: 在喷嘴板中，从燃料喷射装置的燃料喷射口流出的燃料的一部分通过撞击在干涉体而被雾化。 同时，燃料部分的流动急剧地弯曲并撞击直接前进并通过喷嘴孔和孔口的燃料，从而将燃料流转向湍流。 此外，孔的两个端部形成非圆形的锐角部。 因此，从角部和喷嘴的角部附近的区域喷射的燃料的液膜形成为薄的尖锐状态，从喷嘴喷出的燃料的液膜的端部容易雾化 由于燃料的液体膜的端部与空气之间的摩擦。

Abstract: A nozzle plate is to be attached to a fuel injection port of a fuel injection device and injects fuel from the fuel injection port into an intake pipe through nozzle holes. The outlet side openings of the nozzle holes are partially blocked by interference bodies to determine the fuel injection directions and form orifices for reducing flows of the fuel at the outlet side openings. The plurality of orifices have different fuel injection directions, fuel fine particles in sprays draw ambient air, and the drawn air is provided with kinetic momentum to generate a spiral air flow. The nozzle plate is formed by cooling and solidifying molten resin having filled the cavity of a die.
