Abstract: PROBLEM TO BE SOLVED: To provide urea water supply equipment reducing the clogging of a jet hole due to the accumulation of deposits and reducing the jetting of urea water to improper directions by reducing the deposition of the deposits to an outlet side of the jet hole, and removing the deposits even when there is deposition of deposits. SOLUTION: A water jetting nozzle 35 is provided facing a jetting nozzle 25 jetting out urea water. Then, the water jetted out from the water jetting nozzle 35 is sprayed on the outlet side of the jet hole 28 of the jetting nozzle 25. Thus, the urea water adhered to the outlet side of the jet hole 28 is washed by the sprayed water. Deposition and accumulated deposits on the outlet side of the jet hole 28 is dissolved no only by the sprayed water, but destroyed by the physical energy of the sprayed water. As a result, the deposition of deposits on the outlet side of the jet hole 28 is reduced, and the deposits are removed even when there is deposition of deposits. COPYRIGHT: (C)2010,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a urea water injection system for securing sure injection of urea water, by reducing clogging of a nozzle port caused by deposit of urea. SOLUTION: This injection system 11 has a valve member 22 and a cylindrical member 21 slidable in the axial direction, on the outer peripheral side of the valve member 22 for opening the nozzle port 37 on an outer wall 36. The cylindrical member 21 opens-closes the nozzle port 37 by moving in the axial direction. Thus, even if a crystal 40 of the urea is deposited on the valve member 22 around the nozzle port 37, the deposited crystal of the urea is removed by the movement of the cylindrical member 21 when injecting the urea water or stopping injection. Thus, the sure injection of the urea water is secured by reducing the clogging of the nozzle port 37 caused by the deposit of the urea. COPYRIGHT: (C)2010,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a urea water pump for ensuring reliable operation of a pump part and supplies of urea water by reducing the precipitation of urea crystals even when the urea water left reduced, and also to provide a urea water injection system using the same. SOLUTION: A suction pipe part 50 has an upper curved portion 54 as an uppermost portion located above a pump discharge portion 27 of the pump part 21. Thus, even when the liquid level of the urea water in a urea water tank 11 is lowered, the liquid level position of the urea water in the pump part 21 at the side of a pump suction portion 26 beyond the upper curved portion 54 of the suction pipe part 50 is located at the same level as a lower end 56 of the upper curved portion 54. The pump part 21 is then immersed in the urea water independently of the liquid level position of the urea water in the urea water tank 11. As a result, an impeller 24 and a casing 23 of the pump part 21 are immersed in the urea water to reduce the precipitation of urea crystals on the impeller 24 and the casing 23.

Abstract: PROBLEM TO BE SOLVED: To provide a fuel injector having a configuration capable of switching the lift characteristics of a valve member depending on the operating conditions, and capable of controlling a lift independently from the variably controlling injection timing and injection period. SOLUTION: The fuel injector has two pressure control chambers 1p1, 1p2 as back-pressure chambers dealing with the operation of a valve member 1b for opening and closing an injection hole 1aa, and lifts the valve member 1b at two levels by controlling the fuel pressure of the two pressure control chambers 1p1, 1p2. The one pressure control chamber 1p1 is connected to a first solenoid valve 8 the opening and closing of which is switchable based on injection start and stop signals while the other pressure control chamber 1p2 is connected to a second solenoid valve 9 the opening and closing of which is switchable based on a signal of the operating condition. The opening and closing of the second solenoid valve 9 switches the fuel pressure status of the pressure control chamber 1p2. COPYRIGHT: (C)2004,JPO

Abstract: PROBLEM TO BE SOLVED: To facilitate opening/closing a needle valve by reducing pressure applied to a needle valve back part when the needle valve is opened, and inject fuel at high injection pressure with good controllability without increasing attraction force, in an injector using a method for directly driving the needle valve by an electromagnetic drive part.
SOLUTION: In the injector I, an armature part 1a is integrally provided in a base end part of the needle valve 1 stored in a bar-shaped body 2, and attraction is enabled by a solenoid 5 in the electromagnetic drive part. In the armature part 1a, back pressure of a pressure control chamber 7 communicated with a high-pressure fuel supply passage is applied, and a control valve 6 for opening/closing a space between the pressure control chamber 7 and a low-pressure fuel outflow passage is attracted and driven by the solenoid 5. When the back pressure of the pressure control chamber 7 is declined to predetermined pressure, the needle valve 1 is lifted by the attraction force of the solenoid 5.

Abstract: PROBLEM TO BE SOLVED: To decrease variation in injection properties or seat ability among individual injectors 1 and to suppress difference in the injection properties even in the same individual injector 1 in the injector opening/closing an outlet 16 by a flat surface 32 while holding a spherical valve element 27 rotatably.
SOLUTION: The spherical valve element 27 is pressed in a storage space 33 from below and held rotatably by this injector 1. When a valve element holding structure is constructed by press fitting of the spherical valve element 27 in this way, variation in a valve element holding parameter is decreased compared to that in a valve element holding structure with caulking work. Thus, the variation in the injection properties or seat ability among the individual injectors 1 can be decreased, and moreover, the difference in the injection properties even in the same individual injector 1 can be suppressed.
