摘要： A liquid injection apparatus includes an injection unit attached to a liquid injection space which is formed by, for example, an intake pipe of an internal combustion engine, and a pressure pump for pressurizing liquid fed from a liquid storage tank to a pressure enabling injection, and for feeding the liquid to the injection unit. In order to atomize the liquid fed from the pressure pump, the injection unit includes a plurality of chambers, each of which has a piezoelectric/electrostrictive element fixed to its wall surface, and a plurality of liquid discharge nozzles. A force which is induced by liquid pressure in the chambers and imposed on the piezoelectric/electrostrictive elements via the walls of the chambers is almost completely canceled by a counterforce induced by liquid pressure in counterforce source chambers. The liquid pressure in the counterforce source chambers is substantially equal to that in the chambers.

摘要： A liquid injection apparatus 10 comprises an injection device 15, and an electro-magnetic injection valve 14 for ejecting pressurized fuel into the injection device. An ejection hole in the electro-magnetic injection valve is connected to a hollow cylindrical hermetically sealed space, which in turn is connected to a liquid ejection nozzle, through a liquid filling port, a liquid supply passage, and a chamber which are included in the injection device. By means of allowing the electro-magnetic injection valve to eject the pressurized fuel at an angle of inclination relative to the center axis of the hollow cylindrical hermetically sealed space, flows of fuel are produced across a wide area in the hermetically sealed space so that large-sized air bubbles are prevented from being formed in the hermetically sealed space. The injection device adds to the liquid an oscillation energy based on a change of volume of the chamber caused by the piezoelectric/electrostrictive element, for atomizing the liquid to be injected.

摘要： The liquid droplet ejection apparatus includes a liquid supply path, a plurality of mutually independent pressurizing chambers, a plurality of liquid introduction bores for establishing communication between the corresponding pressurizing chambers and the liquid supply path, and a plurality of ejection nozzles for establishing communication between the corresponding pressurizing chambers and the exterior of the liquid droplet ejection apparatus. An ejection bore formed at the end portion of the ejection nozzle has a hollow cylindrical form and the inside diameter thereof increases toward an ejection opening. When a potential difference is applied between two electrodes of a piezoelectric/electrostrictive element, a ceramic sheet forming the upper wall of the pressurizing chamber deforms to thereby cause a change of the volume of the pressurizing chamber. Thus, liquid pressure within the pressurizing chamber increases to thereby cause simultaneous ejection of a plurality of liquid droplets from the ejection opening.

摘要： A liquid injection apparatus includes an injection unit having piezoelectric/electrostrictive elements; a solenoid-operated on-off discharge valve for discharging fuel under pressure into the injection unit; and an electrical control unit. The electrical control unit sends a solenoid valve on-off signal to the solenoid-operated on-off discharge valve on the basis of operating conditions of an engine, whereby liquid fuel is fed under pressure to the injection unit from the solenoid-operated on-off discharge valve. When liquid pressure in the injection unit detected by a liquid feed path pressure sensor is judged to be in the process of increasing or lowering, the electrical control unit activates the piezoelectric/electrostrictive elements, thereby atomizing injected fuel. When the detected liquid pressure in the injection unit is judged to be a constant, low pressure, the electrical control unit inactivates the piezoelectric/electrostrictive elements, thereby reducing electrical consumption.
