    摘要： A fuel injection system comprising a fuel injection pump, at least one fuel injection nozzle connected thereto, and a control device for varying the rate of injection of the system according to varying engine parameters. The control device has a variable volume chamber, the volume of which is varied by a piston located by a piezoelectric actuator. The variable volume chamber and a pumping chamber of the pump is intermittently connected by a passage which is specifically designed in such a manner that the fluid communication between the chambers, during the delivery stroke of a pump plunger, is provided only for an initial stage of the delivery stroke. A rate of injection is controlled in the initial stage to perform a pilot injection. In the subsequent stage, in which there is no need for rate-of-injection control, the variable volume chamber is isolated from the pumping chamber in order to relieve the piezoelectric actuator from an excessively high fuel pressure that would cause degradation of the piezoelectric elements.

    摘要： A piezoelectric flow control valve comprising a slidable closure member (22) for controlling a flow of fluid through a fluid passage (42) between a fluid inlet (40) and a fluid outlet (32). The closure member (22) is biased toward a normally closed position by a plunger (70) responsive to a hydraulic pressure in a pressure chamber (78) which is in fluid communication with the fluid inlet (40) through a restriction and with a pumping chamber (96) of a piezoelectric pump (72). In order to prevent fluid leakage under situations wherein the fluid pressure at the fluid inlet (40) is not high enough to ensure closure of the member (22), the present invention provides spring biased pressure mechanism (106) for biasing the closure member (22) toward the normally closed position and override means (130) for overriding the pressure mechanism (106) in response to a predetermined pressure at the fluid inlet (40).

    摘要： An electronically controllable, ultra-high pressure fuel injector comprises a differential pressure type injection nozzle which is opened and closed by an actuating element operated by a hydraulic power cylinder including a piston received in a working chamber. Working fuel to the working chamber of the power cylinder is ON/OFF controlled by an electronically controllable solenoid valve which when energized releases the pressure in the working chamber to open the injection nozzle. In order to ensure that the power cylinder is controlled by a compact, high response solenoid valve, the construction of the power cylinder and the injection nozzle is such that the force applied to the power cylinder piston by the working fuel pressure in the working chamber is substantially greater than the force applied to the actuating element by the fuel pressure in the pressure chamber in the injection nozzle or the fuel pressure in the passage for supplying the working fuel. Preferably, the fuel injector is provided with an injection rate control arrangement such as a flow control arrangement for limiting the flow rate of working fuel as it enters the working chamber and for increasing the flow rate of the working fuel as it is released therefrom, so that the rate of injection increases gradually at the outset of fuel injection but rapidly drops at the completion of the injection.

    摘要： A multiitem indicating device for indicating a title of a desired item, its units and a detected electrical value corresponding to the desired item comprises a pair of drums around which a plurality of titles and their units are indicated respectively, and which are coaxially connected by a connecting shaft so as to be rotated integrally about an axis thereof. An angular position detecting means includes a code plate and a code sensor for detecting an angular position of the two drums and producing electric signals corresponding to said angular position and a figure indicator disposed in a groove surrounded by the two drums and the connecting shaft. Since the title and the detected value and the unit which correspond to the title can be detected on the same straight line on the same plane, the obtained data can be easily and precisely observed.
