Abstract: PURPOSE: To arrange so that a high-pressure injection may be realized in a short period of time, by providing a pressure amplification mechanism to increase the pressure of fuel introduced into a fuel chamber and at the same time, installing a pressure accumulation nozzle which opens when a fuel pressure in above a prearranged pressure level, on a fuel injection valve body.  
     CONSTITUTION: In the process of metering where a spool valve 2 of a control valve 28 is at an uppermost position, a fuel supply channel 3 is open into a passage 4 through the intermediary of a through groove 13 and a low-pressure fuel is fed into a fuel chamber 18 on a pressure amplification mechanism A. Simultaneously fuel upward of an amplification piston 16 is caused to leak from a leakage passage 7 through a passage 6 and a through groove 15, so that the amplification piston 16 and a plunger 17 are moved upward. Then a spool valve 2 is brought down by means of a solenoid 1 at an electric signal. For this reason, a low-pressure fuel flows into a passage 5 from the through groove 13 and following the downward movement of the piston 16 and the plunger 17, fuel in the fuel chamber 18 enters a pressure accumulation chamber 21 for a pressure accumulation nozzle B through a check valve 19.

Title: Trouble detecting method for inverter air conditioner and protection operation method
Inventor: UNITA HIROYUKI
IPC: F24F11/02
Filed: 1990-06-26
Abstract: PURPOSE:To enable detection of accurate information without depending upon the delivery temperature of a compressor and the piping temperature of a heat exchanger as in a conventional method by a method wherein, provided a source current value detected by a current transformer is below a given current value when the working frequency of a compressor exceeds a given frequency, it is decided that the current transformer has failed. CONSTITUTION:By detecting that a current value detected by a current detecting circuit 7 is below a given current value when the working frequency of a compressor 15 exceeds a given frequency, disconnection of a current transformer 8 is detected. By deciding that disconnection occurs after a lapse of a given time starting from the starting of a compressor, disconnection of the current transformer 8 is more reliably decided without being influenced by behavior of a current during the rise of running of the compressor. It may be theoretically detected that the comparing value of a detecting current value is higher than zero ampere. However, since a current can not be detected from a constitutional point of view of the current detecting circuit 7 until a current matching a voltage value exceeding the forward voltage of a diode bridge 9 flows, decision at a value near a zero ampere is impracticable, and decision to a detectable value is carried out in consideration of the noise margin of a circuit.
