<p>A fuel feed pump capable of compactly forming a fuel pressurizing means, reducing a contact load at an area where a rotating power is converted to a reciprocating one, and changing a contacting form to a surface contact so as to provide high efficiency and reliability, wherein an oscillating cylinder and an oscillating piston are combined with each other so as to form a crank pin drive, a spring for pressing the piston against a cam in an intake stroke is eliminated, and an intake path is formed in a crank pin and the oscillating piston so as to provide an action as an intake valve to open and close a communication between the crank pin intake path and the piston intake path.</p> |
