Patent JP-S63253129-A (JP)
Title: Fuel injection controller for internal combustion engine
Inventor: TAGUCHI ATSUSHI
IPC: F02D1/08
Filed: 1987-04-07
Abstract: PURPOSE:To flush and remove foreign substances as well as to prevent any hindrance of fuel injection from occurring by dividing a spool storage chamber to be interconnected to a pump pressure chamber into a spill chamber and a transformer chamber, and connecting a spill passage, leading to the pump pressure chamber, to the spill chamber. CONSTITUTION:At the time of fuel injection, a solenoid valve 100 is closed, pressure in a pump pressure chamber 19 goes up whereby fuel is sprayed out of a fuel injection nozzle 20. At the time of stopping the fuel injection, the solenoid valve 100 is opened, and a transformer chamber 115 is opened as well. A spool 110 is moved by a pressure drop in the transformer chamber 115 and thereby fuel in the pump pressure chamber 10 is split into a pump low pressure chamber 5 by way of a spill chamber 125 and a spill passage 126, thus the fuel injection comes to an end. At this time, pressure in this spill chamber 125 is equal to that in the pump low pressure chamber 5, while the transformer chamber 115 is interconnected to a lower pressure part than the pump low pressure chamber 5 via the opening. Consequently, spill's displacement becomes large enough by a pressure differential between the spill chamber 125 and the transformer chamber 115 so that foreign substances held between an end face of the spool 110 and a seat surface of the spill chamber 125 can be flushed and removed.

Title: Rotation controller for expansion turbine
Inventor: ASAKURA HIROSHI
IPC: F25B9/06
Filed: 1988-04-08
Abstract: PURPOSE:To control in a wide extent the temperature range of a braking gas within a loop, to enlarge a control range and to effect the sufficient rotation control for an expansion turbine by controlling a refrigerant flow rate in a loop heat exchanger interposed on the way of a control loop for a brake blower, in proportion to the number of rotations of the expansion turbine. CONSTITUTION:When the number of rotations of an expansion turbine 2 increases, a flow rate control valve 30 is opened in proportion to the increased number of its rotations, and a refrigerant flow rate in a loop heat exchanger 18 is increased. According to this increase of the refrigerant flow rate, a braking gas within a brake loop 3 is cooled down and its density becomes high, thereby exhibiting a great braking force. If liquid nitrogen is used as refrigerant (low- temperature fluid) in this case, the inlet temperature in a brake blower 4 can be lowered to the temperature (-196 deg.C) of the liquid nitrogen, so that a great braking force is obtainable. Thus, the temperature of the braking gas within the loop can be controlled in a range of -196-0 deg.C by the adjustment of the flow rate control valve 30, and as a result, a control range is widened by 30-100% and the rotation of the turbine 2 can be sufficiently controlled.
