摘要： In the DME fuel supply device for a diesel engine, the time necessary to retrieve DME fuel remaining in the injection system after stopping the diesel engine into the fuel tank can be reduced. In a non-injection state, a three-way valve (71) is controlled to be OFF to form a communication passage in the direction indicated by the arrow B and a two-way valve (72) is controlled to be ON. DME fuel delivered from a feed pump (5) is delivered to an aspirator (7), passed from an inlet (7a) to the outlet (7b) thereof and returned to a fuel tank (4). That is, the DME fuel circulates via the aspirator. A vapor-phase pressure delivery pipe switching solenoid valve (75) is controlled to be ON and opened so that flow can pass through a vapor-phase pressure delivery pipe (73) connecting the vapor-phase (4a) in the fuel tank (4) and the inlet of the fuel gallery (11). DME fuel in a liquid state remaining in the fuel gallery (11), an overflow fuel pipes (8) and (9) is delivered under pressure to a suction port (7c) by the high pressure of the vapor-phase (4a).

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： In a state in which a high-pressure control solenoid valve is driven to control the pressure in a common rail (refer to Step S100), when the pressure in the common rail exceeds a predetermined value (refer to Step S104), a driving current determined by a prescribed value map that defines the correlation between the pressure in the common rail and the driving current of the high-pressure control solenoid valve is corrected based on an actual pressure in the common rail and the driving current of the high-pressure control solenoid valve at the actual pressure (refer to Steps S106, 108, S110, 112), and the corrected driving current is passed to the high-pressure control solenoid valve, thereby ensuring appropriate and stable injection control even when there exists a variation in operational characteristics among pressure control valves.

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： A fuel feed pump is provided that has a fuel flow-rate regulating valve, on the inlet side. The fuel flow-rate regulating valve includes a housing with a fuel inlet port and a fuel outlet port, a valve mechanism for controlling the flow rate of the fuel from the inlet port to the outlet port, and a regulating mechanism for regulating a backpressure to control the position of a needle valve of the valve mechanism in response to a system pressure, to thereby control the flow rate by controlling the fuel flow through an opening provided in a valve chamber. This arrangement makes it difficult for contamination to accumulate, and also enables a low-cost implementation.

摘要： In a negative pressure boosting device of the present invention, upon depression of a pedal at a normal speed, an input shaft 11 and a valve plunger 10 move forward to close a vacuum valve 15 and open an atmospheric valve 16 and a power piston 5, a valve body 4, and an output shaft 24 move forward. In the initial stage of operation, hooks 27c and 31a are not engaged with each other so that a cylindrical member 27 does not move forward, thereby shortening the stroke of the input shaft 11 as compared to a conventional one. Upon rapid depression of the pedal, a press face 10a presses a pressed face 27e so as to deform an engaging arm portion 27b, thereby disengaging the hooks 27c and 31a from each other. The cylindrical member 27 is moved backward by a spring 30 to push a vacuum valve portion 12b so that the atmospheric valve portion 12a is spaced apart from the atmospheric valve seat 14 more rapidly than that of the service braking, thereby increasing the jumping amount and thus rapidly intensifying the output.

摘要： A sun gear 6 is concentrically, rotatably disposed inside an internal gear 4. Plural planet gears 8, carried by a planetary carrier 10, are disposed between and in meshing engagement with the internal gear 4 and the sun gear 6. The planetary carrier 10 is connected to a shaft extending from an engine while the internal gear 4 and the sun gear 6 are connected to output shafts. The internal gear 4 is molded by a plastic working, followed by a thermal treatment including soft-nitriding, a nitriding and a carburizing hardening step. The inner surface of the internal gear 4 is formed with internal gear teeth 4b, except for an axial portion 4d, while a spline groove 4a is formed on the outer surface of the internal gear 4 at a location corresponding to the portion 4d where no internal teeth 4b are formed for engagement with a spline 2a on a housing 2. The internal gear 4 is reduced in size while improving the mechanical strength thereof.

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.
