    摘要: The present invention provides a motor drive apparatus which improves a trade-off relation between a stable position detection and noise at its driving. A sensorless drive operation circuit calculates by operation a zero cross point (point p) of a voltage of a position detection phase at the next interval, using time information measured based on an output signal from a comparison circuit at the previous interval and the present interval. After the point p has been calculated, points a and b are detected by interrupting a predetermined time drive current.

    摘要: According to the present invention, a fuel injection apparatus includes a casing having a control pressure chamber for storing fuel supplied from fuel passage, a needle valve to which fuel stored in the control pressure chamber applies pressure in the valve closing direction, a valve device for interrupting communication between the fuel passage and the control pressure chamber to seal fuel in said control pressure chamber, and volume changing device for expanding volume of the control pressure chamber after fuel is sealed in the control pressure chamber by the valve device. According to the above fuel injection device, pressure in the control pressure chamber is reduced while the fuel is stored therein by the volume changing device, the nozzle needle is lifted, and injection is started. For this reason, it is not necessary to supply surplus fuel in addition to the injection fuel during the fuel injection. In this way, the fuel supply pump is made smaller in size, and efficiency for use of supplied fuel can be improved. Further, since high-pressure fuel is not discharged from the fuel injection apparatus, pulsation within the common rail can be suppressed, and fuel injection can be stabilized.

    摘要: To provide a fuel injection pump which can sufficiently and stably supply fuel to a fuel pressurization chamber during a fuel intake stroke, a plunger chamber, a spill port and a spill passage are mutually communicable, while a reflux passage, an intake gallery, an intake passage, an intake port and the plunger chamber are mutually communicable. A reflux passage communicates with a damping chamber through a communication passage. The spill passage and the reflux passage communicate with each other, and when a spill valve opens, high-pressure fuel within the plunger chamber spills from the spill valve and into the intake gallery through the reflux passage, causing pulsation having a pressure level difference to the spill fuel. When the pulsation wave passes through the damping chamber, as the level difference in the pulsation wave is reduced, a sufficient quantity of fuel can stably be supplied from the intake gallery to the plunger chamber.
