FUEL PRESSURE REGULATING MECHANISM FOR FUEL INJECTION DEVICE |
摘要 |
PROBLEM TO BE SOLVED: To properly hold a pressure in a fuel gallery chamber in spite of a temperature change by providing a temperature compensating device to regulate the opening of a communication passage according to temperature, a coupling part through which a fuel gallery chamber formed in the body of a fuel injection device and a fuel lead-out pipe outside a body are intercoupled. SOLUTION: The angle of advance control mechanism of a fuel injection pump controls a fuel suction time through control of the position of a spill sleeve fitted in a fuel gallery chamber 1a. The device body 3 of a temperature compensating device Al is screwed in a fuel injection device body 1, and a return spring 6 is fitted internally of a stopper 7 in the valve chamber 3a of the device body 3. A control valve 5 having an orifice opening and a heat- sensitive element are fitted externally thereof. The heat-sensitive element is filled with a heat-sensitive agent, the volume of which is expanded togetherwith the increase of temperature, throughout a portion extending from the interior of a heat-sensitive part 4a to a body part 4b. The opening of an orifice 3b is regulated through slide displacement of a control valve 5 through a piston rod 4c along with volume expansion of the heat-sensitive agent. |
