Title: Pressure accumulation type fuel injection device
Inventor: GOTSUTOROOPU HAAGU
IPC: F02M45/00
Filed: 1990-01-31
Abstract: PURPOSE: To prevent a supply pump from being overloaded, by releasing suction with a minimum demand volume in a suction pipe of a pump through a throttle when the pressure in an accumulator reaches a maximum value, and by partially communicating the pressure pipe with the suction pipe. CONSTITUTION: A supply pump sucks up fuel from a suction pipe 15 through the rotation of an eccentric cam 14, and supplies pressurized fuel into an injection nozzle 7 through operation of a magnet valve 8 through a check valve 5, an accumulator 3, a pressure pipe 4 and a supply pipe 6. In a maximum charge condition of the accumulator 3, although the accumulator piston 17 ascends overcoming a sprint 18, a passage 20 in a spool valve 19 ensures a minimum cross-sectional area of the suction pipe 15 so as to partly communicate the pressure pipe 4 with the suction pipe 15 in order to prevent the pump from racing. Further, when the accumulator piston 7 comes to a position where a maximum accumulating pressure is obtained, the flow-out cross- sectional area 22 is opened, and fuel in a minimum discharge volume flows out through a return pipe 23 so as to cope with heating operation when the injection volume approaches zero, in order to prevent the temperature from being abnormally increased. Thereby it is possible to prevent the supply pump from being overloaded.

Title: Airtightness inspecting apparatus for double pipes
Inventor: NAGANO SHIGEFUMI
IPC: G01M3/26
Filed: 1985-02-04
Abstract: PURPOSE:To ensure the examination of the airtightness of doubles pipes by a simple method, by arranging an inner tube in a hollow body in an airtight manner, sealing compressed air into the hollow body, in which the double pipes to be examined are inserted, and measuring the pressure change. CONSTITUTION:Both opening ends of an elastic inner tube 4, which is inserted in a hollow body 1, are folded outward and sealed by caps 5 in an airtight manner. Both end parts of a flexible inner pipe 2a and an outer pipe 2b are sealed by a bonding material 2c in an airtight manner and double pipes are formed. The double pipes 2 are placed at a specified position in the hollow body 1. When compressed air is sealed in the hollow body 1 through an injecting port 7, the inner tube 4 is expanded and compresses the outer pipe 2a. When the double pipes 2 are airtight, the volume of a hollow part 2d is not changed. The pointer of a pressure gage 11 is not changed after a specified time has elapsed. Therefore, the airtightness of the double pipes can br readily examined without destruction. The examination can be performed regardless of the material of the outer pipe of the double pipes and the sealing means of the inner pipe.
