<p>PROBLEM TO BE SOLVED: To improve the flow of liquid between a valve seat and a valve body in an intake valve, in a forcible valve-type triple piston pump. SOLUTION: A liquid guide 44 is fixed on the peripheral part on the upstream side end of a valve body 40 and provided with a recessed bent surface 66 more projecting in the upstream direction on the outer side in the radial direction on the upstream side. Liquid allowed to flow through the outer side in the radial direction of a seat valve 28 in opening of an intake valve 46 collides with the recessed bent surface 66, restrained from being splashed toward the valve seat 28, and guided to the inner side in the radial direction along the recessed bent surface 66.</p> |
