Abstract
PURPOSE:To improve the stability of the injection performance by forming pressure equalizing passages on a plunger barrel and forming a pressure equalizing groove communicated to a reservoir section and capable of communicating to the pressure equalizing passages is formed on a plunger. CONSTITUTION:Pressure equalizing passages 18, 20 communicated to the valve holder chamber 24a of each delivery valve 22 respectively are formed on a plunger barrel 4. A pressure equalizing groove 31 communicated to a reservoir section 3 and communicated to the delivery valve 22 of other cylinder during the distribution operation to one cylinder and capable of communicating to the pressure equalizing passages 18, 20 is formed on a plunger 5. The valve holder chamber 24a of the delivery valve 22 and the reservoir section 3 of a pump casing 1 are communicated at the certain time after the injection is completed, thereby the residual pressure in an injection tube after each injection is made equal to the internal pressure of a pump. The stability of the injection performance can be improved accordingly.
