とを特徴とするポンプ装置。 A valve housing hole is formed in the housing, a flow rate adjustment valve is fitted into the valve housing hole, and the flow rate adjustment valve is slid to adjust the pressure fluid discharged from the discharge port to a substantially constant flow rate, thereby forming a discharge port. In the pump device, in which the excess flow is bypassed to the pump suction port through a bypass passage opened in the valve housing hole, the housing includes a bypass passage extending in a direction perpendicular to the bypass passage and the bypass passage extending in a direction perpendicular to the bypass passage. a fluid supply path that opens into the bypass passage at a position eccentrically outward relative to the fluid supply passage; and a fluid supply passage that extends parallel to the fluid supply passage and opens into the bypass passage on the opposite side of the fluid supply passage across the bypass passage. A pump device characterized in that a fitting hole is formed, and a guide rod that deflects the fluid flowing through the bypass passage toward the fluid supply path is fitted into the fitting hole.
