Claims

[Scope of Claim for Utility Model Registration] A pulsation pressure operating chamber 6 of a fuel supply pump 5 is communicated with the crank chamber 1 of the overhead valve engine E via a push rod chamber 2, a communication port 3, and a communication pipe 4, and the communication port 3 In the pulsating pressure intake device for driving the fuel supply pump of the engine, which is configured by opening at the lower part 8 of the side wall 7 of the push rod chamber 2, the chamber portion 10 facing the communication port 3 in the push rod chamber 2 is oil-proofed. Cover with the upper part 13 of the cover 12,
The communication port 3 is communicated with the push rod chamber 2 through the oil-proof space 14 in the oil-proof cover 12, and the boss outer circumferential gap between the lower circumferential wall 15 of the push rod chamber 2 and the outer circumferential wall 17 of the tappet boss 16 facing the push rod chamber 2 is provided. 18, the lower part 19 of the oil-proof cover 12
the locking tool 20 from the upper part 13 of the oil-proof cover 12.
for driving a fuel supply pump for an engine, characterized in that the locking tool 20 is configured to project toward the oil-proof space 14 side, and the distal end 21 of the locking tool 20 is inserted into the communication port 3 in such a manner as to prevent upward movement. Pulse pressure intake device.
