摘要： PROBLEM TO BE SOLVED: To provide a fluid controlling solenoid valve, preventing foreign matter contained in blow-back gas from an engine due to change with the passage of time from being deposited in a volume chamber through a communication hole formed in the valve or blocking up the communication hole.
SOLUTION: This fluid controlling solenoid valve includes: a solenoid part 1 disposed in the interior of an intake pipe where the air flows to generate electromagnetic attractive force; a valve part 2 integrated with the solenoid part 1 and having a valve 10 brought into contact with and separated from a seat part 18 formed on the inner wall surface of the intake pipe by the electromagnetic attractive force; and a contractable bellows 12 constituting a volume chamber with the valve 10, communicated with the engine side through a communication hole 13 formed in the valve 10 and canceling the pressure difference between the upstream side and the downstream side of the valve 10. The valve part 2 is provided with air circulating means 11, 30 allowing air to flow from the upstream side to the downstream side of the valve 10 through the communication hole 13.

摘要： PROBLEM TO BE SOLVED: To obtain a proportional solenoid valve for improving oscillation resistance by reducing the self-excited oscillation region of a valve element.
SOLUTION: A drain side passage 15d comprises at least four even-numbered exhaust passage holes 15e arranged with an equal interval one another in the peripheral direction of a valve sheet member 15. The sectional areas of respective exhaust passage holes 15e are equal one another. Additionally, the total of the sectional area of all exhaust passage holes 15e is set to 1 to 2 times larger than the sheet area of a sheet section 15b.

摘要： PROBLEM TO BE SOLVED: To prevent a seal defect caused by foreign matter jammed between plates so as to prevent lowering of a flow rate of a pump, by providing foreign matter collection grooves formed on faces that are surfaces of a first plate and a second plate and are contact with a reed valve. SOLUTION: Collecting grooves 29, 30 for collecting foreing matter are respectively provided to plates 13, 14 that sandwich a reed valve 15 therebetween. When a piston is down, fuel flows into a pump chamber through an intake valve 15a of the reed valve 15. When the piston is up, the intake valve 15a is closed and a discharge valve 15b is opened so that the fuel in the pump chamber is discharged. If the foreign matter is jammed between the reed valve 15 and the plates 13, 14 sandwiching the reed valve 15 therebetween, the foreign matter is moved, by vertical motion of the reed valve 15, the interior in a wedged-manner to be collected in the collecting grooves 29, 30. Since the foreign matter is collected in the collecting grooves 29, 30, time to jam the foreign matter between the reed valve 15 and the plates 13, 14 is lessened. Accordingly, deformation of the reed valve 15 and deposition of the foreign matter are prevented so that a seal property of the reed valve 15 is maintained.

摘要： PROBLEM TO BE SOLVED: To provide a variable delivery fuel system capable of maintaining variation of fuel pressure in a delivery pipe and injection quantity from injection valve small, and of a simple control method. SOLUTION: This variable delivery fuel supply system is provided with a relief fuel passage 6 connecting a suction side of a fuel pump 4 and a pressurizing camber 4e over a suction valve 4a of the fuel pump 4, a solenoid valve 7 provided on the relief fuel passage 6 and controlling delivery of the fuel pump 4 by opening during a designated period in a delivery stroke of the fuel pump 4, and a control unit 108 controlling a open timing of the solenoid valve 7. In open and close actions of the solenoid valve 7, a timing of turning on electricity is fixed on a designated timing against suction and delivery strokes of the fuel pump 4, the control unit 108 changes a timing of turning off electricity to control delivery of the fuel pump 4.
