摘要： A fuel injection pump including a valve opening and closing an overflow passage formed in a body of the pump to connect a high pressure chamber to a low pressure chamber. The low pressure chamber is provided for reserving low pressure fuel, and the high pressure chamber is provided for pressurizing fuel sent from the low pressure chamber and for discharging the pressurized fuel to fuel injectors. A plunger has intake grooves which open the feed passage to communicate the high pressure chamber with the low pressure chamber on an intake action of the pump. The body of the pump has a feed passage formed therein which connects the high pressure chamber to a control chamber. The pressure in the control chamber is changed by the expansion and contaction of a piezoelectric actuator, and the pressure in the control chamber urges the valve in a direction in which the valve closes the overflow passage. A start and end of a fuel injection period, and a fuel injection ratio (a pilot fuel injection), can be controlled by the opening and closing of the valve.

摘要： Disclosed is a piezoelectric control valve which is arranged midway in a passage for supplying a high-pressure fuel to a fuel injection valve, and opens and closes this passage according to expansion and contraction of a piezoelectric element laminate. The valve body of the piezoelectric control valve is slidably held in a bore into which a high-pressure fuel passage connected to the fuel injection valve and a low-pressure fuel passage communicating with a fuel storage portion are opened. An annular groove is formed on the peripheral surface of the valve body, and the high-pressure fuel passage and the low-pressure fuel passage can communicate with each other through this annular groove. A piston moving reciprocatively according to expansion and contraction of the piezoelectric element laminate is provided, and a pressure chamber is formed between the piston and the valve body. The pressure in the pressure chamber is increased and decreased by the reciprocative movement of the piston, and by this increase and decrease of the pressure in the pressure chamber, the valve body is moved to connect the high-pressure fuel passage and the low-pressure passage to each other or to disconnect these passages from each other.

摘要： A piezoelectric actuator comprises a housing having an inside cavity in which is mounted a column of piezoelectric elements having interleaved electrodes. The column of piezoelectric elements is mounted within a sealed enclosure which divides the inside cavity of the housing into an inner space receiving the column of piezoelectric elements and an outer space. The inner space is filled with a flowable, electrically insulative, thermally conductive material such as silicone oil held in direct contact with and in a heat transfer relationship with the column of piezoelectric elements. The silicone oil serves to isolate the column of piezoelectric elements and the electrodes from moisture and other foreign materials that would otherwise affect an insulation breakdown voltage. A cooling liquid is adapted to be circulated through the outer space surrounding the enclosure to absorb heat transferred thereto from the column of piezoelectric elements through the flowable thermally conducting material. The piezoelectric actuator may be incorporated with a fuel injection nozzle to form a pump injector which pressurizes and injects fuel at each energization of the column of piezoelectric elements.

摘要： A hydraulic control valve having a piezoelectric actuator comprises an expansible sleeve loosely received within a bore of the valve housing, with one end thereof being fixedly or stationarily mounted relative to the housing and the other end thereof being expansibly mounted within the bore. A slidable first piston is mounted within the bore of the valve housing and is urged against the other end of the expansible sleeve. This first piston floatingly supports one end of the piezoelectric actuator, the other end of which is supported by a second piston which is slidably mounted within the sleeve and is coupled to a valve member operable to cooperate with a valve seat to open and close an inside fuel passage communicating an inlet port with an outlet port. The linear expansion of the sleeve due to a change in the ambient temperature causes the first piston to displace in one direction together with the piezoelectric actuator supported thereby so that the linear expansion of the piezoelectric actuator occurring in the opposite direction due to a similar ambient temperature change is counterbalanced whereby the second piston, serving as an output member of the piezoelectric actuator, is maintained at a constant distance with respect to the valve member regardless of change in the ambient temperature. Such a temperature compensation structure enabling precise positioning of the second piston ensures improved injection timing and injection quantity control of a fuel injection system for an internal combustion engine.

摘要： A flow control device advantageously used in a fuel injection system for a diesel engine. The flow control device includes a spool valve defining on its sides first and second chambers which are connected with each other by means of a throttle. The second chamber is connected to a high pressure pipeline connecting a fuel pump with a fuel injector, while the first chamber is selectively opened to a relief line by means of an electrically operated valve. A cylinder has an annular groove opened to the relief line. When the valve is opened, the first chamber is opened to the relief line. A pressure difference is thus created between the first and the second chambers so as to move the spool valve to open. Thus fuel injection is stopped.

摘要： A piezoelectric actuator comprising a tubular casing and an elongated piezoelectric member disposed in the casing. The piezoelectric member has axially spaced ends, one of which abuts the shoulder of the casing. The piezoelectric member expands and contracts in response to an applied voltage, another end effecting a pumping operation. The piezoelectric member forms first and second longitudinal surfaces extending along substantially the entire length of axis. The piezoelectric member is formed as a lamination of a plurality of piezoelectric plates, to each of which is applied an electrode element on one of lateral surfaces. The electrode elements protrude on the first or second surfaces, alternately. First and second electrode members are located at the first and second surfaces, respectively. The first surface may be a surface of an opening which extends through the piezoelectric member, and the second surface may be a surface of an outer cylindrical surface of the piezoelectric member. Since the outer cylindrical surface is kept in contact with the inner surface of the casing, no flashover occurs between the surfaces. The second surface also may be a surface of another opening which extends through the piezoelectric member. In this embodiment, since the outer cylindrical surface has no electrode element, no flashover occurs between the outer cylindrical surface and the inner surface of the casing. A valve apparatus having the above-mentioned actuator and a method of manufacturing a piezoelectric member are also disclosed.
