Abstract

PURPOSE:To prevent the erroneous operation caused by vibration in a diaphragm operation control valve to control the pressure of injection fuel by restraining the movement of a diaphragm by a frictional force without disturbing normal operation. CONSTITUTION:The fuel sent under pressure is injected from an injection device 5 by the signal of a computer, and the excessive fuel is introduced into a chamber A of a pressure control device 9. When its pressure is higher than a set pressure, it is conducted through a gap between a valve 7 and a seat 6, and returned to a fuel tank via a passage 3. A member 11 with a proper length in the direction of operation is fast fixed on a diaphragm 8, and fitted to a plastic member 12 fixed on a cover 13 to be slided with a small friction of operation. The member 12 is provided with a hole 12a not to change the effective diameter of the diaphragm 8. This construction permits to restrain vibration, prevent the erroneous operation caused by the vibration, and improve the durability of the diaphragm.
