摘要： A fuel injection apparatus comprises a first storing device for temporarily storing cut-off fuel drained after the termination of a fuel injection, a second storing device of changeable volume for temporarily storing fuel for intake, the second storing device having a movable member which is movable in response to the quantity of fuel introduced therein, a detector for producing a detection signal showing an actural position of the movable member and a clamping device responsive to an electric signal for clamping the movable member. The clamping device is actuated to clamp the movable member in response to the detection signal when the desired amount of fuel is stored therein. The adjusted quantity of fuel stored in the second storing device is supplied to a high pressure chamber together with the cut-off fuel stored in the first storing device during the next fuel intake stroke of a fuel injection pump. As a result, extremely high accuracy control of fuel quantity can be realized.

摘要： A suction space is disposed to selectively communicate with a pump working chamber defined at one end of a plunger via a first communication passageway in which a solenoid valve is arranged, or with suction ports formed in the plunger and communicating with the pump working chamber via a second communication passageway having a restriction therein. The solenoid valve alternately opens and closes for ordinary fuel injection during operation of the engine other than at the start thereof. A selector valve keeps the first communication passageway closed and simultaneously keeps the second communication passageway opened for fuel injection through collaboration of the suction ports with the second communication passageway, in place of the alternate opening and closing of the solenoid valve.

摘要： A pair of cut-off ports are formed in a plunger and a plunger barrel at a predetermined axial location and registrable with each other to spill pressurized fuel into a zone under lower pressure. A communication passageway communicates a pump working chamber defined by the plunger at one end thereof with the zone under lower pressure. A solenoid valve is arranged across the communication passageway for blocking same. Control means controls the solenoid valve to cause same to selectively assume an open position and a closed position. While the plunger moves toward the pump working chamber, the solenoid valve is closed by the control means to start injection of fuel present in the pump working chamber, and upon registration of the cut-off ports with each other, the fuel injection is terminated.

摘要： A bypass controller (30) controls ON/OFF of a three-way electromagnetic valve (62) according to a detection value of a cam chamber sensor (12a). When the cam chamber sensor (12a) detects a viscosity of lubricant exceeding a predetermined allowable value, the three-way electromagnetic valve (62) is controlled to turn ON so that the output side of an oil separator (13) communicates with a bypass route (61). The pressure in the cam chamber (12) is reduced to or below the atmospheric pressure by suction of a compressor (16) with a check valve (14) regulating the pressure in the cam chamber (12) to the atmospheric pressure or above in the bypassed state. When the detection value of the viscosity of the lubricant output by the cam chamber sensor (12a) has become the predetermined allowable value or below, the three-way electromagnetic valve (62) is controlled to turn OFF so that the output side of the oil separator (13) communicates with the check valve (14) and the bypass route (61) is cut off.

摘要： A hydraulic circuit for a working machine is provided which prevents a decrease in the working speed of a clamshell bucket upon expansion of an expansion arm, so that improvement of the operability can be achieved. A hydraulic circuit for a working machine is configured such that a clamshell bucket is attached to a tip end of an expansion arm and the expansion arm and the clamshell bucket are operated by pressure oil supplied from a common pressure source. The operating pressure is reduced for driving the expansion arm to the expansion side based on the operating pressure for opening the clamshell bucket. By the configuration, the clamshell bucket can be opened rapidly, and improvement of the operability is achieved.

摘要： Since an aspirator 7 is disposed at a position lower than a fuel gallery 11 and an overflow fuel pipe 81, DME fuel remaining in the fuel gallery 11 and the overflow fuel pipe 81 can be more efficiently retrieved to a fuel tank 4 by a combined force of gravity and suction force produced in a suction port 7c of the aspirator 7. Since the vapor-phase pressure delivery pipe opening/closing solenoid valve 74 is disposed at a position higher than the fuel gallery 11, DME fuel in a liquid state remaining in the fuel gallery 11 and the overflow fuel pipe 81 is forcedly delivered under pressure to the suction port 7c of the aspirator 7 by a combined force of gravity and the pressure of a vapor phase 4b in the fuel tank 4. Accordingly, time taken to retrieve the DME fuel in an injection system to the fuel tank after the stop of a diesel engine.

摘要： In an injection pump element 2, a communication route for communicating an injection pipe 3 connected to a fuel liquid outlet 212 and an inner peripheral surface of a plunger barrel 25 is formed by a purge passage 242 formed in a delivery valve seat 24, a purge passage 252 formed in the plunger barrel 25, and a purge port 253. When the injection pump element 2 is in a non-injection state, the plunger 26 is rotated circumferentially to such a rotational position that a purge groove 265 formed in an outer peripheral surface of the plunger 26 and a purge port 253 formed in an inner peripheral surface of the plunger barrel 25 are communicated to each other. The purge groove 265 is communicated to a fuel gallery 11 via a hole 263 and a notch 262. When the injection pump element 2 is in the non-injection state, the injection pipe 3 is communicated to the fuel gallery 11 even if the delivery valve 23 is closed.

摘要： A distributor-type fuel injection pump of the type including a magnetic valve disposed on the head portion of a pump body, wherein a pair of oil seals is disposed on opposite sides of the feed pump, and a bypass passage bypasses the cam chamber and connects a discharge side of the feed pump and an inlet side of the magnetic valve. With this construction, the fuel is delivered without passing through the cam chamber. On the other hand, the lubrication oil is introduced into the cam chamber through clearances between the drive shaft and the bearings and through passageways defined in the drive shaft. The cam assembly or other movable components are lubricated exclusively with the lubrication oil, so that the fuel injection pump operates stably over an extended period of time.
