Abstract

PURPOSE:To prevent a valve seating sound by preventing oil in an oil chamber of a plunger from passing through at a time of stop of an engine by providing an oil guide in the plunger so that air is not sucked at a restart of the engine when a pressure chamber acts a sucking operation. CONSTITUTION:In case an oil hole 24' of a plunger 16 is located at the top while an engine stops, the oil in the inside of an oil guide rib 30 which is connected with the oil hole 24' and the oil in an oil chamber 19 are not led out at all. When the oil hole 24' is located at the bottom, the oil in the inside of the oil guide rib 30 passes through first, but further extraction at the oil in the oil chamber 19 is inhibited through levels of an inlet 32a of a notch 31a side and an outlet 32b at a notch 31b side of a helical groove 32 extending over length of three quarters of the circumference. With this, passing of the oil while the engine stops can be prevented and a valve seating sound can be excluded as well.
