のデリバリバルブ。[Claims for Utility Model Registration] 1. In a delivery valve of a fuel injection pump in which the valve opening pressure is set by a delivery spring disposed between the plunger of the fuel injection pump and the injection valve, A delivery valve for a fuel injection pump, characterized in that an auxiliary spring is formed in series with a temperature sensitive member and whose spring pressure changes depending on the temperature, and the opening pressure is corrected depending on the fuel oil temperature. . 2. The temperature sensitive member is a shape memory alloy member.
A delivery valve for a fuel injection pump according to claim 1 of the utility model registration claim. '3 When the fuel oil temperature is below a predetermined temperature, the auxiliary spring expands with a spring pressure greater than the spring pressure of the delivery spring to achieve the pre-paris. Utility model registration claim 1, characterized in that the valve opening pressure is increased by compressing a spring, and when the predetermined temperature is exceeded, the spring pressure becomes smaller than the spring pressure of the delivery spring, thereby lowering the valve opening pressure. Delivery valve of the fuel injection pump according to item 1.
