Inventor: SUZUKI SHINICHI
IPC: G03B7/26
Filed: 1994-09-06
Abstract: PURPOSE: To hold an insulating member so as to be prevented from falling off even when a battery is inserted in any way by arranging folded parts in both ends of a battery contact piece and inserting the folded parts into an opening part, formed in the insulating member so as to be engaged. CONSTITUTION: An insulating member 5 is fitted and engaged in a battery contact piece 4 for the purpose of reverse conduction prevention. On both sides of the insulating member 5, an opening part 5a and an end edge 5b are formed. Therefore, an end edge in a folded part and the end edge 5b in the opening part 5a are brought into contact with each other. When a battery 11 is correctly loaded, a projection 11b of a plus electrode is higher than the gap between the insulating member 5 and the projection of the battery contact piece 4 while the outside diameter of the projection 11b is smaller than the inside width of the insulating member 5, so that conduction with the battery contact piece 4 is carried out.  On the other hand, in case of erroneous loading, the outside diameter of the battery 11 is larger than the inside width of the insulating member 5, so that a minus electrode is interrupted by means of the insulating member 5, and consequently, the conduction with the battery contact piece 4 is prevented.

Title: Fuel injection device
Inventor: MATSUMOTO SHUICHI
IPC: F02M47/00
Filed: 1995-08-22
Abstract: PROBLEM TO BE SOLVED: To enable fuel to be injected even when injection starvation of fuel is quick and fuel supplying pressure is low, and also to miniaturize a device. SOLUTION: A pressure control chamber 65 is provided on the opposite nozzle hole side of a control piston 22 to be reciprocated together with a needle valve. An annular clearance 64 is formed between a fuel passage 62 communicated with a high-pressure fuel passage and the pressure control chamber 65 by the outer peripheral wall of the control piston 22 and the inner peripheral wall of an injector body 13. Since fuel is easily allowed to flow in the annular clearance 64 in the high rotation of the engine in which common rail pressure Pc becomes high pressure, quick fuel injection starvation can be realized by facilitating inflow of fuel to the pressure control chamber 65. Moreover, since pressure of the pressure control chamber 65 is to be easily decreased when the common rail pressure Pc is low, fuel can be injected also in the low pressure.
